到上述荷重。另一方面，上述荷重的方向，是使V溝表面 14c與V溝表面14d的間隔變窄的方向，所以在其周面分 別與V溝表面14c與V溝表面14d接觸的滾動滾子15L， 承受幾乎所有上述荷重。 相反地，當荷重從下方（第4圖記載的箭頭1 b沿著所 示的方向）施加於桿部2 2b時，其荷重的方向，是將V溝 表面14c與V溝表面14d的間隔加寬的方向，所以在其周 面分別與V溝表面14c與V溝表面14d接觸的滾動滾子 15L，幾乎沒有承受到上述荷重。另一方面，上述荷重的 方向，是使V溝表面14a與V溝表面14b的間隔變窄的方 向，所以在其周面分別與V溝表面14a與V溝表面14b接 觸的滾動滾子15H，承受幾乎所有上述荷重。 在直線移動導引單元22，當荷重從上方施加於桿部 2 2b時，在圖中在下側的導引通路i3l所收容的複數個滾 動滾子15L，承受幾乎所有上述荷重，而當荷重從下方施 加於桿部22b時，在圖中在上側的導引通路13H所收容的 複數個（與滾動滾子15L同樣數量）滾動滾子15H，承受幾 乎所有上述荷重。於是，直線移動導引單元22，不管是在 -8 - 201206614 從上方及下方的任一方將荷重施加於桿部22b的情況，顯 示相等的耐荷重性。因此，直線移動導引單元22，當安裝 於各種機械裝置時，不需要考慮施加於桿部22b的荷重的 方向，所以能簡單地使用。 可是，在將直線移動導引單元22安裝於各種機械裝 置之後，通常會有較大的荷重從上方及下方的任一方繼續 施加於桿部22b。例如，當較大的荷重繼續從上方施加於 桿部22b時，上述荷重幾乎全部繼續施加於在導引通路 13L所收容的複數個滾動滾子15L，另一方面，上述荷重 幾乎沒有施加於在導引通路13H所收容的複數個滾動滾子 15H »因此，與導引通路13H的V溝表面14a、14b相比 ，與滾動滾子15L的周面接觸的導引通路13L的V溝表 面14c、14d會大幅磨耗。 於是，習知的直線移動導引單元22，當藉由長時間的 使用而讓其中一方的導引通路的直線狀V溝極端磨耗時， 即使另一方的導引通路的直線狀V溝幾乎沒有磨耗，也必 須要更換成其他的直線移動導引單元》 直線移動導引單元22，用能將施加於桿部22b的荷重 分散到更多數量的滾動滾子，則能發揮越優異的耐荷重性 。如上述，當較大的荷重從上方及下方的任一方繼續施加 於桿部22b時，上述荷重幾乎全部繼續施加於在其中一方 導引通路所收容的複數的滾動滾子。於是，另一方的導引 通路的複數個滾動滾子，幾乎沒有承受上述荷重，而無法 有效地發揮耐荷重性。 -9 201206614 本發明的課題，要提供一種直線移動導引單元，能防 止其中一方的導引通路的直線狀V溝的極端磨耗情形，因 此能發揮優異的耐久性。 本發明的課題，要提供一種直線移動導引單元，除了 上述優異的耐久性之外，也能發揮優異的耐荷重性。 [用以解決課題的手段] 本發明者，發現：在具備有兩條以上用來收容滾動滾 子的導引通路的直線移動導引單元，藉由將收容於各導引 通路的滾動滾子的配置方式進行設計，則可使施加於桿部 的荷重分散到在各導引通路所收容的滾動滾子，藉此則可

201206614 在本發明的直線移動導引單元，由於將施加於桿部的 荷重分散到各導引通路的滾動滾子，所以可防止其中~方 的導引通路的直線狀V溝的極端磨耗的情形。藉由將各導 引通路的滾動滾子配置向預定的方向，則在施加於桿部的 荷重的方向也能發揮因應的優異耐荷重性。 【實施方式】 首先，使用附圖來說明本發明的直線移動導引單元（ 平行配置型）。第6圖，是將在本發明的直線移動導引單 元（平行配置型）所使用的滾動滾子15H、15L予以保持的 保持板16的構成例子的顯示圖。第7圖是顯示使用有將 第6圖所示的保持板16的本發明的直線移動導引單元的 構造的剖面圖。 直線移動導引單元3 1，是由：互相鄰接的兩條桿部 31a、31b、與將圓柱狀的滾動滾子15H、15L予以保持的 保持板1 6所構成。 在兩條桿部3 1 a、3 1 b的互相相對向的側面，沿著上 述桿部的長度方向且相對向形成有：互相平行的兩條直線 狀V溝。也就是說，在桿部3 1 a的側面形成有兩條直線狀 V溝1 1 a、1 1 b，且在桿部3 1 b的側面也形成有兩條直線狀 V溝12a、12b。直線狀V溝1 la與直線狀V溝12a，互相 相對向而形成導引通路1 3 Η。同樣地，直線狀V溝1 1 b與 直線狀V溝12b，互相相對向而形成導引通路13L。 保持板16，保持著：在上述導引通路13H串列（在導 -14- 201206614 引通路的長度方向排成一列的狀態）且可滾動地所收容的 三個以上的圓柱狀的滾動滾子15H、以及在上述導引通路 13L串列且可滾動地所收容的三個以上的圓柱狀的滾動滾 子 1 5L。 滾動滾子15H的周面，分別接觸於：導引通路13H 的相對向的V溝表面14a、14b。同樣地，滾動滾子15L 的周面，分別接觸於：導引通路13L的相對向的V溝表面 14c ' 14d » 爲了將三個以上（合計爲η個）的滾動滾子15H互相區 別，在顯示滾動滾子的圖號1 5Η的右側記載有1、2、… 、（η-1)、η的圖號。同樣地，爲了將三個以上（合計爲η 個）的滾動滾子15L互相區別，在顯示滾動滾子的圖號 1 5 L的右側記載有1、2.....(η-1 )、η的圖號。通常收容 於各個導引通路的滾動滾子的數量（也就是上述η的値）， 設定在2〜100個，較佳爲3〜80個，尤其爲5〜60個的 範圍內》 本發明的直線移動導引單元3 1，其兩條導引通路13Η 、13L的滾動滾子15H、15L，其特徵是符合下述的（1)及 (2)的要件的配置方式。 (1) 其中一方的導引通路13L的全部的滾動滾子15L(也就 是滾動滾子15L,、15L2.....151^·,)、15Ln)，配置成將 各中心軸朝互相相同的方向》 (2) 另一方的導引通路13H的滾動滾子15H之中，至少一 個的滾動滾子（例如滾動滾子15H2)，配置成將其中心軸朝 -15- 201206614 向與上述（1)的滾動滾子15L的中心軸的方向相同的方向 ’而且另外至少兩個的滾動滾子（例如兩個滾動滾子15H! 、15Hn)，配置成將各中心軸朝向與上述（1)的滾動滾子 15L的中心軸的方向交叉的方向，且互相沒有鄰接。 針對配置滾動滾子15H、15L的理由，在以下來說明 〇 首先，在第4圖及第5圖所示的習知的直線移動導引 單元22的情況，當荷重從上方（沿著第4圖所記載的箭頭 1 a所示的方向）施加於桿部22b的情況，該荷重幾乎都沒 有施加於導引通路13H的滾動滾子15H，而幾乎都施加於 導引通路13L的滾動滾子15L。因此，習知的直線移動導 引單元22，在長時間使用的情況，會讓其中一方的導引通 路13L的直線狀V溝極端地磨耗。 另一方面，如第6圖及第7圖所示，導引通路13H的 滾動滾子15H之中，將至少一個滾動滾子，例如滾動滾子 15H2,配置成將其中心軸朝向與導引通路13L的滾動滾子 1 5L的中心軸的方向相同的方向的話，則當荷重從上方（沿 著第7圖記載的箭頭la所示的方向）施加於桿部31b時， 該荷重會分散施加到：導引通路13L的滾動滾子15L(也 就是滾動滾子15L,、15L2.....15L(n·,)、15Ln)、與導引 通路13H的滾動滾子15H2。因此，本發明的直線移動導 引單元3 1，即使維持長時間使用，也能防止：其中一方的 導引通路1 3 L的直線狀V溝的極端的磨耗情形。 由於上述荷重施加的滾動滾子的數量增加，所以對於 -16- 201206614 從上方施加到桿部31b的荷重的耐荷重性也提升。 如第6圖及第7圖所示，導引通路13H的滾動滾子 15H之中，除了上述至少兩個滾子（例如兩個滾動滾子 151^、15Hn)之外的剩下的全部滾動滾子（也就是15H2、… 、15Η(η.η)，配置成將其中心軸朝向與導引通路13L的滾 動滾子1 5 L的中心軸的方向相同的方向的話，則對於從上 方施加到桿部31b的荷重的耐荷重性會更提升。 與上述不同的至少兩個滾動滾子，例如兩個滾動滾子 15H】、15 Hn，配置成將各中心軸朝向與滾動滾子i5L的中 心軸的方向交叉的方向，且互相並不鄰接的話，則能防止 桿部31b朝上下方向的並不適當的微動。 假設兩條導引通路的全部滾動滾子，配置成將各中心 軸朝與第6圖所示的滾動滾子15L的中心軸的方向相同的 方向的話，藉由該滾動滾子，雖然能承受從上方施加於桿 部31b的荷重而能支承桿部31b，可是無法承受從下方施 加於桿部31b的荷重而支承桿部31b。因此，例如，當藉 由從外部施加的振動或衝擊，從下方施加荷重時，桿部 31b朝上方微動，接著從上方施加荷重時，桿部31b朝下 方微動，會有讓桿部3 1 b的直線前進性降低的情形。 因此，在本發明的直線移動導引單元31，如上述爲了 抑制桿部31b的朝上下方向的微動，所以使用兩個滾動滾 子15H!、15Hn，能承受從下方施加於桿部31b的荷重而 能支承桿部3 1 b。 如上述，配置成將中心軸朝向與導引通路13L的滾動 -17- 201206614 滾子15L的中心軸的方向交叉的方向的滾動滾子的數量爲 一個（或者即使滾動滾子的數量爲兩個，將兩個滾動滾子 配置成互相鄰接）的話，例如藉由從外部施加的振動或衝 擊，以上述一個滾動滾子（或者配置成互相鄰接的兩個滾 動滾子）爲中心，桿部31b會稍微傾斜移動（上下微動），會 使桿部31b的直線前進性降低。 爲了有效地防止桿部的上下方向的微動，上述要件（2) 的兩個滾動滾子15山、151^，如第6圖所示，是在導引 通路所收容的滾動滾子15H之中配置在兩端的滾動滾子較 佳。 上述要件（2)的兩個滾動滾子，也就是配置成將中心軸 朝向與導引通路13L的滾動滾子15L的中心軸的方向交叉 的方向的兩個滾動滾子之中，其中一方的滾動滾子，也可 具備於與鄰接於上述滾動滾子15H,的滾動滾子15H2爲相 同的位置，另一方的滾動滾子，也可具備於與鄰接於上述 滾動滾子15Hn的滾動滾子15H(n-n爲相同的位置。例如， 上述其中一方的滾動滾子，具備於與滾動滾子15Η,爲相 同的位置，另一方的滾動滾子，具備於與滾動滾子15Η(η.υ 爲相同的位置。 在以上的說明，如第6圖及第7圖所示，以將荷重從 上方施加於直線移動導引單元3 1的桿部3 1 b的情況爲例 ，針對對於從上方施加於桿部31b的荷重的耐荷重性的提 升效果加以說明。相反地，在荷重從下方施加於桿部3 1 b 的情況，如果將上述直線移動導引單元31的上下方向逆 -18- 201206614 向使用的話，則可使對於從方施加於桿部31b的荷重的耐 荷重性提升。 在上述第6圖及第7圖所示的本發明的直線移動導引 單元31，是讓導引通路13L的滾動滾子15L符合上述要 件（1)的配置方式，且讓導引通路13H的滾動滾子15H符 合上述要件（2)的配置方式。相反的，本發明的直線移動導 引裝置，也可作成讓導引通路13H的滾動滾子15H符合 上述要件（1)的配置方式，且讓導引通路13L的滾動滾子 15L符合上述要件（2)的配置方式。 第8圖是將在本發明的直線移動導引單元（平行配置 型）所使用的滾動滾子予以保持的保持板的其他構成例子 的顯示圖。在第8圖所示的保持板16，在上述要件（2)的 兩個滾動滾子15H!、15Hn之間，配置有：將中心軸朝向 與該滾動滾子151、15Hn的中心軸的方向相同的方向的 兩個以上（滾動滾子15H的三個中有一個的比例的數量）的 滾動滾子。 如果使該滾動滾子（例如滾動滾子15H4)的數量增加的 話，則能有效地防止如上述的桿部的朝上下方向的微動， 而能使對於從下方施加於桿部的荷重的耐荷重性提升。 第9圖是將在本發明的直線移動導引單元（平行配置 型）所使用的滾動滾子予以保持的保持板的另外構成例子 的顯示圖。在第9圖所示的保持板16，上述要件（2)的另 —方的導引通路的全部滾動滾子15H，配置成將各中心軸 朝向與鄰接的滾動滾子的中心軸的方向交叉的方向。 -19- 201206614 例如，滾動滾子1 5H2，配置成將其中心軸朝向與鄰 接的滾動滾子15Η,、15Η3的中心軸的方向交叉的方向。 同樣地，滾動滾子1 5Η3，配置成將其中心軸朝向與鄰接 的滾動滾子15Η2、15心的中心軸的方向交叉的方向。 被保持板16所保持的各滾動滾子的配置，是藉由在 保持板1 6的開口部所具備的突起1 7所固定。 如第9圖所示，在直線移動導引單元的其中一方的導 引通路所收容的全部滾動滾子15L，配置成將各中心軸朝 向互相相同的方向，且在另一方的導引通路所收容的全部 滾動滾子15Η，配置成將各中心軸朝向與鄰接的滾動滾子 的中心軸的方向交叉的方向的話，則容易製造長度不同的 直線移動導引單元。 也就是說，如果要預先製作保持著滾動滾子15Η、 15L的長度的較長保持板16的話，藉由將該保持板16切 斷成因應於直線移動導引單元的長度，則能簡單地製造出 長度不同的直線移動導引單元。 接著針對本發明的直線移動導引單元（交叉配置型）來 說明》 交叉配置型的直線移動導引單元的構造，除了保持板 所保持的滾動滾子的配置方式的不同之外，與上述平行配 置型的直線移動導引單元的構造相同。在以下，針對交叉 配置型的直線移動導引單元的構造，節省與上述說明重複 的說明，僅針對與平行配置型的直線移動導引單元的差異 點，也就是針對保持著滾動滾子的保持板的構造進行說明 -20- 201206614 第10圖是將在本發明的直線移動導引單元（交叉配置 型）所使用的滚動滾子予以保持的保持板的構成例子的顯 示圖。 本發明的直線移動導引單元（交叉配置型），其兩條導 引通路的滾動滾子15H、15L，其配置方式符合下述（1)及 (2 )的要件。 (1)另一方的導引通路的滾動滾子15H之中，至少兩個滾 動滾子（例如兩個滾動滾子15H!、15H(n-U)，配置將各中 心軸朝向互相相同方向，且互相不鄰接，且配置有：將中 心軸朝向與上述至少兩個滾動滾子的中心軸的方向交叉的 方向的另外至少一個的滾動滾子（例如滾動滾子15H2)。 針對以該方式配置滾動滾子15H、15L的理由，如以 下說明。 首先，另一方的導引通路的滾動滾子15H之中，至少 兩個滾動滾子，例如兩個滾動滾子15H!、1 ，配置 將各中心軸朝向互相相同方向，且互相不鄰接的話，則該 兩個滾動滾子15H,、15H(n.n，與第6圖所示的平行配置 型的直線移動導引單元具備的兩個151、15Ηη —樣，能 發揮防止桿部朝上下方向的微動的功能。 另一方面，配置有：將中心軸朝向與上述兩個滾動滾 子151、的中心軸的方向交叉的方向的另外至少 一個的滾動滾子，例如滾動滾子15H2、15H4…的話，則 從上方施加到桿部的荷重，會分散施加到：上述的滾動滾 -21 - 201206614 子1 5H2、1 5H4…、與上述其中一方的導引通路的滾動滾 子15L之中，配置.成將中心軸朝向與滾動滾子15H2的中 心軸的方向相同的方向的滾動滾子 > 例如滾動滾子15L!、 15L3…》因此，如第1〇圖所示的具備有將滾動滾子15H 、15L保持的保持板16的本發明的直線移動導引單元（交 叉配置型），也能防止其中一方的導引通路的直線狀V溝 的極端磨耗情形。 在第10圖所示的保持板16，上述要件（1)的其中一方 的導引通路的全部的滾動滾子15L，是配置成將各中心軸 朝向與鄰接的滾動滾子的中心軸的方向交叉的方向，而上 述要件（2)的另一方的導引通路的全部滾動滾子15H，也配 置成將各中心軸朝向與鄰接的滾動滾子的中心軸的方向交 叉的方向。 於是，在兩條導引通路所收容的將中心軸朝向其中一 方配置的滾動滾子（也就是15H!、15L2、15H3、…）的總數 、與配置成將中心軸朝向與上述方向交叉的方向的滾動滾 子（也就是15L,、15H2、15L3、…）的總數，是互相相等。 因此，第10圖所示的具備有將滾動滾子15H、15L保 持的保持板1 6的本發明的直線移動導引單元，例如，各 種荷重（例如力矩荷重、徑向荷重、或軸向荷重）施加於直 線移動導引單元時的耐荷重性、與當施加與上述荷重的方 向相反方向的荷重時的耐荷重性，大致相等。也就是說達 成不會受到各種荷重的方向影響的具有平衡性的耐荷重性 ，所以能發揮優異的通用性。 -22- 201206614 第11圖是將在本發明的直線移動導引單元（交叉配置 型）所使用的滾動滾子予以保持的保持板的其他構成例子 的顯不圖。 在第11圖所示的保持板16，另一方的導引通路的滾 動滾子15H之中，兩個滾動滾子15Ηι、15Hn，配置成將 各中心軸朝向互相相同的方向，且互相不鄰接。該兩個滾 動滾子151、151，發揮用來防止桿部朝上下方向的微 動的功能。 爲了有效地防止桿部的上下方向的微動，如第11圖 所示，上述兩個滾動滾子15H!、15Hn的各個，是在導引 通路所收容的滾動滾子15H之中配置在兩端的滾動滾子較 佳。 另一方面，配置有將其中心軸朝向與上述兩個滾動滾 子15H!、15Hn的中心軸的方向交叉的方向的其他至少一 個滾動滾子，例如配置有滾動滾子15H2…、15Η(η.1}的話 ，則從上方施加到桿部的荷重，會分散施加到：上述的滾 動滾子15Η2…、1511(^,)、與上述其中一方的導引通路的 滾動滾子15L之中，配置成將中心軸朝向與滾動滾子 1 5 Η2的中心軸的方向相同的方向的滾動滾子，例如滾動滾 子15L!、15L3…、151^^)。因此，如第1 1圖所示的具備 有將滾動滾子15H、15L保持的保持板16的本發明的直線 移動導引單元（交叉配置型），也能防止其中一方的導引通 路的直線狀V溝的極端磨耗情形。 而在兩條導引通路的滾動滾子15H、15L以第11圖所 -23- 201206614 示配置的情況，在兩條導引通路所收容的將中心軸朝向其 中一方配置的滾動滾子（也就是151、15Hn、15L2、15L4 …、15Ln)的總數、與配置成將中心軸朝向與上述方向交 叉的方向的滾動滾子（也就是15H2.....15H(„.,) ' 15L, ' 151〇、…15L(n.i>)的總數，是互相不同。 於是，第11圖所示的具備有將滾動滾子15H、15L保 持的保持板16的本發明的直線移動導引單元（交叉配置型） ，與如第4圖及第5圖所示的習知的直線移動導引單元22 的情況相比，承受從上方施加於桿部的荷重而支承桿部的 滾動滾子（也就是，15H2.....15H(n-n、15L,、15L3、… 1 5 L^.u)的數量較多，所以讓對於上述荷重的耐荷重性提 升。 第12圖是將在本發明的直線移動導引單元（交叉配置 型）所使用的滾動滾子予以保持的保持板的另外構成例子 的顯示圖。在第8圖所示的保持板16，在第8圖所示的保 持板16，在上述要件（2)的兩個滾動滾子15H,、15Hn之間 ，配置有：將中心軸朝向與該滾動滾子的中 心軸的方向相同的方向的兩個以上（滾動滾子15Η的三個 中有一個的比例的數量）的滾動滾子。 如果使該滾動滾子（例如滾動滾子15Η4)的數量增加的 話，則能有效地防止如上述的桿部的朝上下方向的微動， 而能使對於從下方施加於桿部的荷重的耐荷重性提升。 第13圖是將在本發明的直線移動導引單元（交叉配置 型）所使用的滾動滾子予以保持的保持板的另外構成例子 -24- 201206614 的顯示圖，是顯示將滾動滾子的其中一個從保持板 下的狀態。 如第13圖所示，也可分別藉由不同的保持板 16L來保持各導引通路的滾動滾子15H、15L。 例如，如果預先準備幾個滾動滾子的配置方式 保持板，則藉由將其中兩片保持板組合使用，則能 在短時間製造出因應於所要求的耐荷重性的直線移 單元。 作爲本發明的直線移動導引單元的保持板，可 與習知的直線移動導引單元的保持板相同的構造。 ，以第13圖所示的保持板16L爲例，針對滾動滾 持板的安裝方法加以說明》 如第13圖所示，在保持板16L，形成有：用 各滾動滾子16L的複數的開口部19。開口部19的 設定成大致橢圓形。例如，滾動滾子1 5L2，以讓其 c與保持板16L大致正交的配置方式，將其插入於 19。將該滾動滾子傾斜移動成讓配置在保持板16L 的端面朝向上方，而傾斜配置成如圖所示的滾動滾· 時，由於其周面接觸於開口部19的緣部，所以無 步傾斜移動。在該狀態，將設置於開口部1 9的上 突起1 7斂縫（使其塑性變形），將各突起1 7接觸於 子15L2的各端面使其卡合。藉此，滾動滾子15L2 朝與上述傾斜移動的方向相反的方向移動。藉由這 序，將複數的滾動滾子，以可旋轉的狀態分別保持 16L卸 16H、 不同的 簡單且 動導引 以使用 在以下 子朝保 來保持 形狀， 中心軸 開口部 的前側 ψ 1 5L4 法進一 下的各 滾動滾 也無法 樣的順 於保持 -25- 201206614 板16L的各開口部19。 第14圖是顯示本發明的直線移動導引單元的其他構 造例子的剖面圖。第15圖是從圖的右側觀察將第14圖的 直線移動導引單元41的滾動滾子15H、15M、15L予以保 持的保持板16H、16M、16L的圖面。 在直線移動導引單元41，在桿部41a形成有三條直線 狀V溝11a、lib、11c，在桿部41b形成有三條直線狀V 溝 12a、 12b ' 12c° 直線狀V溝11 a與直線狀V溝12a，互相相對向，形 成導引通路13H。同樣地，直線狀V溝lib與直線狀V溝 12b，互相相對向，形成導引通路13M。同樣地，直線狀 V溝11c與直線狀V溝12c，互相相對向，形成導引通路 1 3L 〇 保持板16H，將在上述導引通路13H所收容的三個以 上的圓柱狀的滾動滾子15H予以保持。同樣地，保持板 16M，將在上述導引通路13M所收容的三個以上的圓柱狀 的滾動滾子15M予以保持。同樣地，保持板16L，將在上 述導引通路13L所收容的三個以上的圓柱狀的滾動滾子 15L予以保持。 第15圖的保持板16H所保持的滾動滾子15H(也就是 15H, ' 15H2.....1 、1 5Hn)的配置，與第 6 圖的保 持板16保持的滚動滾子15H的配置相同。第15圖的保持 板16M所保持的滾動滾子15M(也就是15M!、15M2..... 15M(n.n、15Mn)的配置，與第6圖的保持板16保持的滾 201206614 動滾子15L的配置相同。 也就是說，第14圖所示的直線移動導引單元41’是 具有：在具備有兩條導引通路的並排配置型的直線移動導 引單元，進一步增加將在導引通路13L配置的滾動滾子 15L保持的保持板16L的構造。 在直線移動導引單元41，在荷重從上方施加於桿部 41b的情況，以讓該荷重分散施加於各導引通路的滾動滾 子的方式，讓增加的保持板16L的滾動滾子15L之中，至 少一個滾動滾子，例如滾動滾子15L2.....15L(n-U，配 置成將各中心軸朝向與導引通路13M的滾動滾子15M的 中心軸的方向相同的方向。 在直線移動導引單元41，從上方施加於桿部41b的荷 重，是分散施加於：導引通路13H的滾動滾子15H2、… 、、導引通路13M的滾動滾子15Mi.....15Mn、 以及導引通路13L的滾動滾子1 5L2.....15L(n-"，所以 能有效地防止各導引通路的直線狀V溝的磨耗。 由於承受從上方施加於桿部41b的荷重而支承桿部 41b的滾動滾子的數量變多，所以對於上述荷重的耐荷重 性更加提升。 導引通路13L的兩個滾動滾子15L!、15Ln，配置成將 各中心軸朝向與滾動滾子15M的中心軸的方向交叉的方向 ，且互相不鄰接，所以能更有效地防止桿部41b的朝上下 方向的微動。 形成於各桿部的直線狀V溝的數量，通常設定爲2〜 -27- 201206614 5條，最好是2條或3條。當直線狀V溝的數量爲3條以 上時，則三條以上的直線狀V溝，等間隔地配置在：形成 有直線狀V溝的桿部的側面的寬度方向較佳。 在本發明的直線移動導引單元，各桿部的各直線狀V 溝的寬度的總計，是在形成有直線狀V溝的桿部側面的寬 度的1/2〜1/5 (50〜20%)的範圍較佳。藉此，各桿部的直 線狀V溝的形成的空間部的容積變小，讓各桿部的剛性增 加，所以防止直線移動導引單元的長度方向的彎曲（彈性 變形）。也就是說，讓直線移動導引單元的長度方向的耐 力矩荷重性提升。例如，在第7圖所示的直線移動導引單 元3 1，各直線狀V溝的寬度的總計，設定成桿部側面的 寬度的約34%。 在本發明的直線移動導引單元，在各桿部形成有兩條 直線狀V溝的情況，該兩條直線狀V溝，分別從形成有 直線狀 V溝的側面的端部，位於該側面的寬度的1 /5〜 1/3(20〜33%)的範圍的位置較佳。藉此，在兩條導引通路 所收容的滾動滾子列的間隔較寬，所以能防止直線移動導 引單元的寬度方向的彎曲（彈性變形）。也就是說，讓直線 移動導引單元的寬度方向的耐力矩荷重性提升。例如，在 第7圖所示的直線移動導引單元3 1，各直線狀V溝，從 形成有直線狀V溝的側面的端面，位於其側面的寬度的約 24%的位置。上述直線狀V溝的位置，代表直線V溝的深 度最大的位置（也就是V溝頂點的位置。 第16圖是使用本發明的直線移動導引單元的直線移 -28- 201206614 動導引裝置的剖面圖。 第16圖的直線移動導引裝置50，例如在基台56隔介 著複數個例如兩個的本發明的直線移動導引單元51、52 而可直線移動地連結著滑動台57。直線移動導引單元51 、52的各構造，除了使用第1〇圖所示的將滾子15H、15L 保持的保持板16的方式以外，與第7圖所示的直線移動 導引單元31的構造相同。 直線移動導引單元51的其中一方的桿部51a,固定在 基台56，且另一方的桿部51b固定在滑動台57。同樣地 ，直線移動導引單元52的其中一方的桿部52a固定在基 台56，且另一方的桿部5 2b固定在滑動台57。 直線移動導引裝置50.，例如依照以下的順序組裝。首 先，將直線移動導引單元51的桿部51a、及直線移動導引 單元52的桿部52a，藉由將分別螺入於基台56的螺栓孔 56a的螺栓59a旋緊，而將其固定在基台56的互相相對向 的側面。接著，在直線移動導引單元51、52上配置滑動 台57。將螺栓59b旋入到該滑動台57的各穿孔57a，而 嵌合於桿部51b、51b的各螺栓孔5 8b。在該狀態，將螺栓 59c旋入到滑動台57的側面的螺栓孔57b而旋緊的話，則 直線移動導引單元51的桿部51a與桿部51b、以及直線移 動導引單元52的桿部52a與桿部52b，分別互相緊固而被 加壓（被施加預壓）。藉此讓各直線移動導引裝置的兩條桿 部與配置在之間的複數滾動滾子，無間隙地緊貼。最後藉 由將各螺栓59b旋緊，則將桿部51b、52b固定於滑動台 -29 - 201206614 57 〇 第17圖是顯示使用有第16圖的直線移動導引裝置50

Jsp> [Description of the Invention] 201206614 [Problem to be Solved by the Invention] In the linear movement guide unit 22 shown in Fig. 4, the load is applied from above (in the direction indicated by the arrow la shown in Fig. 4). In the case of the rod portion 22b, the direction of the load is a direction in which the interval between the V groove surface 14a and the V groove surface 14b is widened, so that the rolling roller 15H which is in contact with the V groove surface 14a and the V groove surface 14b on the circumferential surface thereof, respectively , almost did not bear the above load. On the other hand, since the direction of the load is a direction in which the interval between the V groove surface 14c and the V groove surface 14d is narrowed, the rolling roller 15L that is in contact with the V groove surface 14c and the V groove surface 14d on the circumferential surface thereof, Withstand almost all of the above loads. Conversely, when the load is applied to the rod portion 2 2b from below (the arrow 1 b shown in Fig. 4), the direction of the load is the interval between the V groove surface 14c and the V groove surface 14d. In the wide direction, the rolling roller 15L which is in contact with the V groove surface 14c and the V groove surface 14d on the circumferential surface thereof hardly receives the above load. On the other hand, since the direction of the load is a direction in which the interval between the V groove surface 14a and the V groove surface 14b is narrowed, the rolling roller 15H which is in contact with the V groove surface 14a and the V groove surface 14b on the circumferential surface thereof, Withstand almost all of the above loads. In the linear movement guide unit 22, when the load is applied to the rod portion 2 2b from above, the plurality of rolling rollers 15L accommodated in the lower guide passage i3l in the drawing are subjected to almost all of the above-mentioned loads, and when the load is from When the lower portion is applied to the rod portion 22b, the plurality of rollers (the same number as the rolling rollers 15L) are accommodated in the upper guide passage 13H in the drawing, and the roller 15H is rolled to receive almost all of the above-described load. Then, the linear movement guiding unit 22 exhibits an equal load-bearing property regardless of whether or not the load is applied to the rod portion 22b from either of the upper side and the lower side at -8 - 201206614. Therefore, the linear movement guide unit 22 does not need to consider the direction of the load applied to the rod portion 22b when it is attached to various mechanical devices, so that it can be easily used. However, after the linear movement guide unit 22 is attached to various mechanical devices, a large load is usually applied to the rod portion 22b from either the upper side or the lower side. For example, when a large load continues to be applied to the rod portion 22b from above, the load is almost always applied to the plurality of rolling rollers 15L accommodated in the guide passage 13L, and on the other hand, the load is hardly applied to The plurality of rolling rollers 15H accommodated in the guide passage 13H. Therefore, the V groove surface 14c of the guide passage 13L that is in contact with the circumferential surface of the rolling roller 15L is smaller than the V groove surfaces 14a and 14b of the guide passage 13H. 14d will be greatly worn. Therefore, in the conventional linear movement guide unit 22, when the linear V-groove of one of the guide passages is extremely worn by long-term use, even if the linear V-groove of the other guide passage is hardly The wear must also be replaced with another linear movement guide unit. The linear movement guide unit 22 can achieve a superior load resistance by dispersing the load applied to the rod portion 22b to a larger number of rolling rollers. Sex. As described above, when a large load is continuously applied to the rod portion 22b from either of the upper side and the lower side, the load is almost always applied to the plurality of rolling rollers accommodated in one of the guide passages. Therefore, the plurality of rolling rollers of the other guide passage are hardly subjected to the above-described load, and the load resistance cannot be effectively exerted. -9 201206614 An object of the present invention is to provide a linear movement guide unit capable of preventing extreme wear of a linear V-groove of one of the guide passages, thereby exhibiting excellent durability.

The above-mentioned "cylindrical rolling roller" is not a rolling roller which represents a strict cylindrical shape. As the above-mentioned cylindrical rolling roller, a rolling roller used in a conventional linear movement guide unit can be used. (For example, a structure in which the peripheral edge of each end surface of the cylinder is chamfered, and a structure having a too drum-like shape in which the circumferential surface of the cylinder protrudes). Alternatively, the side surface of the linear V groove may be deformed (for example, in a curved shape) in accordance with the shape of the rolling roller. [Effect of the invention] -13 - 201206614 The linear movement guide unit of the present invention is applied to the rod Since the load of the portion is dispersed to the rolling rollers of the respective guide passages, it is possible to prevent the extreme wear of the linear V-grooves of the guide passages. By arranging the rolling rollers of the respective guide passages in a predetermined direction, it is possible to exhibit an excellent load resistance in the direction of the load applied to the rod portion. [Embodiment] First, a linear movement guide unit (parallel arrangement type) of the present invention will be described with reference to the drawings. Fig. 6 is a view showing a configuration example of a holding plate 16 for holding the rolling rollers 15H and 15L used in the linear movement guide unit (parallel arrangement type) of the present invention. Fig. 7 is a cross-sectional view showing the structure of the linear movement guide unit of the present invention using the holding plate 16 shown in Fig. 6. The linear movement guide unit 31 is composed of two rod portions 31a and 31b adjacent to each other and a holding plate 16 for holding the cylindrical rolling rollers 15H and 15L. On the side faces of the two rod portions 3 1 a and 3 1 b facing each other, two linear V-grooves which are parallel to each other are formed in the longitudinal direction of the rod portion. That is, two linear V-grooves 1 1 a and 1 1 b are formed on the side surface of the rod portion 3 1 a, and two linear V-grooves 12a and 12b are formed on the side surface of the rod portion 3 1 b. The linear V-grooves 1 la and the linear V-grooves 12a are opposed to each other to form a guide passage 13 Η. Similarly, the linear V groove 1 1 b and the linear V groove 12b face each other to form the guide passage 13L. The holding plate 16 holds three or more cylindrical rolling rollers that are rotatably accommodated in the series of the guide passages 13H (in a state in which the guide passages are arranged in the longitudinal direction of the guide-14-201206614). 15H and three or more cylindrical rolling rollers 15L that are accommodated in the above-described guide passage 13L and are rollably accommodated. The circumferential surface of the rolling roller 15H is in contact with the opposing V groove surfaces 14a and 14b of the guide passage 13H. Similarly, the circumferential surface of the rolling roller 15L is respectively in contact with the opposite V groove surface 14c' 14d of the guide passage 13L » In order to distinguish three or more (total of n) rolling rollers 15H from each other, The figure number of the scroll wheel 1 is displayed on the right side of the figure 5, and the figure numbers of 1, 2, ..., (η-1), and η are described. Similarly, in order to distinguish three or more (total of n) rolling rollers 15L from each other, 1, 2 is indicated on the right side of the figure number 15 L indicating the rolling roller. . . . . (η-1), the figure number of η. Usually, the number of rolling rollers (that is, the above-mentioned η) accommodated in each of the guide passages is set in the range of 2 to 100, preferably 3 to 80, particularly 5 to 60. The linear movement guide unit 3 1, the rolling rollers 15H, 15L of the two guide passages 13A, 13L, are characterized by the arrangement of the requirements of the following (1) and (2). (1) All of the rolling rollers 15L of one of the guide passages 13L (that is, the rolling rollers 15L, 15L2. . . . . 151^·,), 15Ln), arranged in the same direction as each of the central axes, (2) at least one of the rolling rollers 15H of the other guide passage 13H (for example, a rolling roller) 15H2), configured to have its central axis toward -15-201206614 in the same direction as the direction of the central axis of the rolling roller 15L of the above (1) and at least two other rolling rollers (for example, two rolling rollers) 15H! and 15Hn) are arranged such that the respective central axes are oriented in a direction intersecting the direction of the central axis of the rolling roller 15L of the above (1), and are not adjacent to each other. The reason for arranging the rolling rollers 15H and 15L will be described below. First, in the case of the conventional linear movement guiding unit 22 shown in FIGS. 4 and 5, when the load is from above (along the fourth) In the case where the direction indicated by the arrow 1 a shown in the figure is applied to the rod portion 22b, the load is hardly applied to the rolling roller 15H of the guide passage 13H, and the rolling roller is applied to the guide passage 13L almost exclusively. 15L. Therefore, in the case where the conventional linear movement guide unit 22 is used for a long period of time, the linear V-groove of the one of the guide passages 13L is extremely worn. On the other hand, as shown in FIGS. 6 and 7, among the rolling rollers 15H of the guide passage 13H, at least one rolling roller, for example, the rolling roller 15H2, is disposed such that its central axis is oriented and guided. When the direction of the central axis of the rolling rollers 15L of the passage 13L is the same, when the load is applied to the rod portion 31b from above (in the direction indicated by the arrow 1a in the seventh diagram), the load is dispersedly applied. To: the rolling roller 15L of the guiding passage 13L (that is, the rolling roller 15L, 15L2. . . . . 15L (n·,), 15Ln), and the rolling roller 15H2 of the guide passage 13H. Therefore, the linear movement guide unit 31 of the present invention can prevent the extreme wear of the linear V-groove of one of the guide passages 1 3 L even if it is used for a long period of time. Since the number of rolling rollers applied by the above load is increased, the load resistance of the load applied to the rod portion 31b from above is also increased for -16 - 201206614. As shown in FIGS. 6 and 7, the remaining rolling of the rolling rollers 15H of the guide passage 13H except for the at least two rollers (for example, the two rolling rollers 151^, 15Hn) Roller (that is, 15H2, ..., 15Η (η. η) is arranged such that the center axis thereof is oriented in the same direction as the direction of the central axis of the rolling roller 15 L of the guide passage 13L, and the load resistance applied to the load applied from the upper portion to the rod portion 31b is further enhanced. . At least two rolling rollers different from the above, for example, two rolling rollers 15H], 15 Hn, are arranged such that the central axes are oriented in a direction crossing the central axis of the rolling roller i5L, and are not adjacent to each other. Therefore, it is possible to prevent an improper fine movement of the rod portion 31b in the vertical direction. Assuming that all the rolling rollers of the two guiding passages are arranged in the same direction as the direction of the central axis of the rolling roller 15L shown in FIG. 6, the rolling roller can withstand The rod portion 31b can be supported by the load applied to the rod portion 31b from above, and the rod portion 31b can be supported without being able to bear the load applied to the rod portion 31b from below. Therefore, for example, when a load is applied from below by vibration or impact applied from the outside, the rod portion 31b is slightly moved upward, and when a load is applied from above, the rod portion 31b is slightly moved downward, and the rod portion 3 1 b is caused. The situation in which the straightness is reduced. Therefore, in the linear movement guide unit 31 of the present invention, as described above, in order to suppress the vertical movement of the rod portion 31b in the vertical direction, the two rolling rollers 15H!, 15Hn can be used to withstand the load applied to the rod portion 31b from below. It is possible to support the rod portion 3 1 b. As described above, the number of rolling rollers arranged to cross the central axis in the direction intersecting the direction of the central axis of the roller -17-201206614 roller 15L of the guide passage 13L is one (or even if the number of rolling rollers is two) If the two rolling rollers are disposed adjacent to each other, for example, by the vibration or impact applied from the outside, the above-described one rolling roller (or two rolling rollers arranged adjacent to each other) is centered, the rod portion 31b The tilting movement (slight up and down) will slightly reduce the linear advancement of the rod portion 31b. In order to effectively prevent the vertical movement of the rod portion in the vertical direction, the two rolling rollers 15 of the above-mentioned requirement (2) are 151, as shown in Fig. 6, which are among the rolling rollers 15H accommodated in the guiding passage. It is better to configure the rolling rollers at both ends. The two rolling rollers of the above requirement (2), that is, two rolling rollers arranged to cross the central axis in the direction intersecting the direction of the central axis of the rolling roller 15L of the guiding passage 13L, one of the two rolling rollers The rolling roller may be provided at the same position as the rolling roller 15H2 adjacent to the rolling roller 15H, and the other rolling roller may be provided with the rolling roller adjacent to the rolling roller 15Hn. 15H (nn is the same position. For example, one of the rolling rollers described above is provided at the same position as the rolling roller 15Η, and the other rolling roller is provided with the rolling roller 15Η (η. υ is the same location. In the above description, as shown in FIGS. 6 and 7, the case where the load is applied from the upper side to the rod portion 3 1 b of the linear movement guide unit 3 1 is taken as an example, and is applied to the rod portion 31b from above. The effect of the load-bearing load on the load is explained. On the other hand, when the load is applied to the rod portion 3 1 b from below, if the vertical direction of the linear movement guide unit 31 is reversed from -18 to 201206614, the slave portion 31b can be applied to the rod portion 31b. The load resistance of the load is increased. The linear movement guide unit 31 of the present invention shown in the sixth and seventh embodiments is such that the rolling roller 15L of the guide passage 13L conforms to the above-described requirement (1), and the guide passage 13H is provided. The rolling roller 15H conforms to the configuration of the above requirement (2). On the contrary, the linear movement guide device of the present invention can also be configured such that the rolling roller 15H of the guide passage 13H conforms to the above-described requirement (1), and the rolling roller 15L of the guide passage 13L conforms to the above requirements ( 2) Configuration method. Fig. 8 is a view showing another example of the configuration of the holding plate for holding the rolling rollers used in the linear movement guide unit (parallel arrangement type) of the present invention. In the holding plate 16 shown in Fig. 8, between the two rolling rollers 15H! and 15Hn of the above-described requirement (2), the central axis is oriented in the direction of the central axes of the rolling rollers 151 and 15Hn. Rolling rollers of two or more in the same direction (the number of the ratio of one of the three of the rolling rollers 15H). If the number of the rolling rollers (for example, the rolling rollers 15H4) is increased, it is possible to effectively prevent the vertical movement of the rod portion as described above, and to withstand the load applied to the load from the lower portion. Sexual improvement. Fig. 9 is a view showing another example of the configuration of a holding plate for holding a rolling roller used in the linear movement guide unit (parallel arrangement type) of the present invention. In the holding plate 16 shown in Fig. 9, all of the rolling rollers 15H of the other guide passages of the above-described requirements (2) are arranged such that the respective central axes are oriented in the direction of the central axis of the adjacent rolling rollers. The direction. -19- 201206614 For example, the rolling roller 15H2 is arranged such that its central axis is oriented in a direction intersecting the direction of the center axis of the adjacent rolling roller 15Η, 15Η3. Similarly, the rolling rollers 15 5 are arranged such that their central axes are oriented in a direction intersecting the direction of the central axes of the adjacent rolling rollers 15 Η 2, 15 . The arrangement of the respective rolling rollers held by the holding plate 16 is fixed by the projections 17 provided in the opening of the holding plate 16. As shown in Fig. 9, all of the rolling rollers 15L accommodated in one of the guide passages of the linear movement guide unit are arranged such that the central axes are oriented in the same direction and the other guide passage is provided. When all the rolling rollers 15 accommodating are arranged such that the respective central axes are oriented in a direction intersecting the direction of the central axis of the adjacent rolling rollers, it is easy to manufacture linear movement guide units having different lengths. That is, if the long holding plate 16 holding the length of the rolling rollers 15A, 15L is to be prepared in advance, by cutting the holding plate 16 into a length corresponding to the linear movement of the guiding unit, it is possible to simply A linear movement guide unit having different lengths is manufactured. Next, the configuration of the linear movement guide unit of the cross-arrangement type will be described with respect to the linear movement guide unit (cross-arrangement type) of the present invention, and is parallel to the above except for the arrangement of the rolling rollers held by the holding plate. The configuration of the linear motion guiding unit of the configuration is the same. In the following, for the configuration of the cross-arranged linear movement guide unit, the explanation overlapping with the above description is saved, and only for the difference point of the linear movement guide unit with the parallel arrangement type, that is, for maintaining the retention of the rolling roller. Description of the structure of the plate -20-201206614 Fig. 10 is a view showing a configuration example of a holding plate for holding a rolling roller used in the linear movement guide unit (cross-arrangement type) of the present invention. In the linear movement guide unit (cross-arrangement type) of the present invention, the rolling rollers 15H and 15L of the two guide passages are arranged in accordance with the requirements of the following (1) and (2). (1) Among the rolling rollers 15H of the other guiding passage, at least two rolling rollers (for example, two rolling rollers 15H!, 15H (nU) are arranged such that the central axes are oriented in the same direction and mutually Not adjacent, and is provided with at least one other rolling roller (for example, rolling roller 15H2) that faces the center axis in a direction crossing the direction of the central axes of the at least two rolling rollers. For configuring the rolling roller in this manner The reason for the sub-ports 15H and 15L is as follows. First, at least two rolling rollers, for example, two rolling rollers 15H!, 1 among the rolling rollers 15H of the other guiding passage, are arranged for each central axis. When facing in the same direction and not adjacent to each other, the two rolling rollers 15H, 15H (n. n, similar to the two 151, 15Ηη provided in the linearly-arranged guide unit of the parallel arrangement type shown in Fig. 6, can function to prevent the lever portion from being slightly moved in the vertical direction. On the other hand, if at least one of the rolling rollers that are oriented in a direction intersecting the direction of the central axis of the two rolling rollers 151, for example, the rolling rollers 15H2, 15H4, etc., is disposed from above. The load applied to the rod portion is distributed and applied to: the rolling roller 21 - 201206614 sub 1 5H2, 1 5H4 ..., and the rolling roller 15L of one of the above-mentioned guiding passages. Rolling rollers that are oriented in the same direction as the direction of the central axis of the rolling roller 15H2 > for example, the rolling rollers 15L!, 15L3, ..." Therefore, as shown in Fig. 1, there are provided rolling rollers The linear movement guide unit (cross-arrangement type) of the present invention of the holding plate 16 held by 15H and 15L can also prevent extreme wear of the linear V-groove of one of the guide passages. In the holding plate 16 shown in Fig. 10, all of the rolling rollers 15L of the guide passages of one of the above-mentioned requirements (1) are arranged such that the respective central axes are oriented in the direction of the center axis of the adjacent rolling rollers. In the direction of intersection, all of the rolling rollers 15H of the other guide passage of the above-described requirement (2) are also arranged such that the respective central axes are oriented in a direction intersecting the direction of the central axis of the adjacent rolling rollers. Then, the total number of rolling rollers (that is, 15H!, 15L2, 15H3, ...) in which the central axis is disposed in one of the two guide passages and the direction in which the central axis is oriented to intersect with the above direction is arranged.

In the case where the rolling rollers 15H and 15L of the two guide passages are arranged as shown in Fig. 11-23-201206614, the rolling rollers accommodated in the two guide passages with the central axis oriented toward one of them are also That is, the total number of 151, 15Hn, 15L2, 15L4, ..., 15Ln) and the rolling roller arranged in the direction in which the central axis is oriented in the above direction (that is, 15H2. . . . . 15H („. ,) '15L, '151〇,...15L(n. The total number of i>) is different from each other. Then, the linear movement guide unit (cross arrangement type) of the present invention including the holding plate 16 holding the rolling rollers 15H and 15L shown in FIG. 11 and the habits shown in FIGS. 4 and 5 In the case of the known linear movement guide unit 22, the rolling roller that supports the rod portion is received by the load applied to the rod portion from above (that is, 15H2. . . . . 15H (n-n, 15L, 15L3, ... 1 5 L^. The number of u) is large, so the load resistance for the above load is increased. Fig. 12 is a view showing another example of the configuration of a holding plate for holding a rolling roller used in the linear movement guide unit (cross-arrangement type) of the present invention. In the holding plate 16 shown in Fig. 8, in the holding plate 16 shown in Fig. 8, between the two rolling rollers 15H, 15Hn of the above-mentioned requirement (2), a central axis is oriented and Rolling rollers of two or more (the number of the ratio of one of the three rolling rollers 15Η) in the same direction of the center axis of the rolling roller. If the number of the rolling rollers (for example, the rolling rollers 15Η4) is increased, it is possible to effectively prevent the vertical movement of the rod portion as described above, and to withstand the load applied to the load from the lower portion. Sexual improvement. Fig. 13 is a view showing a further configuration example of the holding plate for holding the rolling rollers used in the linear movement guide unit (cross-arrangement type) of the present invention - 24,066,066, which is a display of the rolling roller. A state from under the retaining plate. As shown in Fig. 13, the rolling rollers 15H, 15L of the respective guide passages may be held by the different holding plates 16L, respectively. For example, if a plurality of rolling roller arrangement retaining plates are prepared in advance, by using two of the retaining plates in combination, a linear shifting unit that responds to the required load resistance can be manufactured in a short time. The holding plate as the linear movement guide unit of the present invention can have the same configuration as the holding plate of the conventional linear movement guide unit. The holding plate 16L shown in Fig. 13 is taken as an example, and the mounting method of the rolling rolling plate will be described. As shown in Fig. 13, in the holding plate 16L, a plurality of openings each of the rolling rollers 16L are formed. Part 19. The opening 19 is set to be substantially elliptical. For example, the rolling roller 15L2 is inserted into the arrangement so that c is substantially orthogonal to the holding plate 16L. The rolling roller is tilted so that the end surface of the holding plate 16L faces upward, and when it is inclined so as to be arranged as shown in the figure, since the circumferential surface thereof contacts the edge of the opening 19, Step tilt to move. In this state, the upper projections 7 provided in the opening portion 19 are caulked (plastically deformed), and the respective projections 17 are brought into contact with the respective end faces of the sub-ports 15L2 to be engaged. Thereby, the rolling roller 15L2 moves in a direction opposite to the direction in which the above-described tilting movement is performed. By this sequence, the plurality of rolling rollers are respectively held in a rotatable state by 16L and 16H, and different simple and dynamic guides are used to maintain the shape in the following sub-back, the front side of the central shaft opening portion ψ 1 5L4 Each of the rolling rolls of the method is not able to follow the opening portions 19 of the plate 16L of the -25-201206614. Fig. 14 is a cross-sectional view showing another configuration example of the linear movement guide unit of the present invention. Fig. 15 is a view showing the holding plates 16H, 16M, and 16L holding the rolling rollers 15H, 15M, and 15L of the linear movement guide unit 41 of Fig. 14 as viewed from the right side of the figure. In the linear movement guide unit 41, three linear V grooves 11a, 11b, 11c are formed in the rod portion 41a, and three linear V grooves 12a, 12b' 12c are formed in the rod portion 41b. Linear V grooves 11a and straight lines are formed. The V-shaped grooves 12a are opposed to each other to form a guide passage 13H. Similarly, the linear V groove lib and the linear V groove 12b face each other to form the guide passage 13M. Similarly, the linear V groove 11c and the linear V groove 12c face each other to form the guide passage 13L 〇 holding plate 16H, and three or more cylindrical rolling rollers housed in the guide passage 13H. 15H will be maintained. Similarly, the holding plate 16M holds three or more cylindrical rolling rollers 15M housed in the above-described guide passage 13M. Similarly, the holding plate 16L holds three or more cylindrical rolling rollers 15L accommodated in the above-described guide passage 13L. The rolling roller 15H held by the retaining plate 16H of Fig. 15 (that is, 15H, '15H2. . . . . The configuration of 1, 5Hn) is the same as that of the rolling roller 15H held by the holding plate 16 of Fig. 6. The rolling roller 15M held by the holding plate 16M of Fig. 15 (that is, 15M!, 15M2. . . . . 15M (n. The arrangement of n, 15Mn) is the same as the arrangement of the roll 201206614 moving roller 15L held by the holding plate 16 of Fig. 6 . That is, the linear movement guide unit 41' shown in Fig. 14 has a linear movement guide unit of a side-by-side arrangement type having two guide passages, and further increases the rolling which will be arranged in the guide passage 13L. The structure of the holding plate 16L held by the roller 15L. In the linear movement guide unit 41, when the load is applied to the rod portion 41b from above, the rolling roller 15L of the added holding plate 16L is allowed to be distributed so that the load is distributed to the rolling rollers of the respective guide passages. Medium, at least one rolling roller, such as a rolling roller 15L2. . . . . 15L (nU) is arranged such that each central axis is oriented in the same direction as the direction of the central axis of the rolling roller 15M of the guide passage 13M. In the linear movement guide unit 41, the load applied to the rod portion 41b from above is dispersed. Applied to: the rolling roller 15H2 of the guiding passage 13H, the rolling roller 15Mi of the guiding passage 13M. . . . . 15Mn, and the rolling roller of the guiding passage 13L 1 5L2. . . . . 15L (n-", it is possible to effectively prevent the wear of the linear V-grooves of the respective guide passages. Since the load applied to the rod portion 41b from above is increased, the number of rolling rollers supporting the rod portion 41b is increased. The load resistance of the load is further improved. The two rolling rollers 15L!, 15Ln of the guide passage 13L are arranged such that the respective central axes are oriented in a direction intersecting the direction of the central axis of the rolling roller 15M, and are not adjacent to each other. Therefore, it is possible to more effectively prevent the vertical movement of the rod portion 41b in the vertical direction. The number of linear V grooves formed in each rod portion is usually set to 2 to -27 - 201206614 5 pieces, preferably 2 or 3 pieces. When the number of the linear V-grooves is three or more, three or more linear V-grooves are arranged at equal intervals in the width direction of the side surface of the rod portion in which the linear V-grooves are formed. In the linear movement guide unit, the total width of each of the linear V grooves of each of the rod portions is in the range of 1/2 to 1/5 (50 to 20%) of the width of the side surface of the rod portion in which the linear V groove is formed. Preferably, the volume of the space portion formed by the linear V-groove of each rod portion is thereby obtained. Small, the rigidity of each rod portion is increased, so that the bending (elastic deformation) in the longitudinal direction of the guide unit is prevented from moving linearly. That is, the torque load resistance in the longitudinal direction of the linear movement guide unit is improved. For example, The total width of each of the linear V-grooves shown in Fig. 7 is set to be about 34% of the width of the side surface of the rod portion. In the linear movement guide unit of the present invention, each rod portion is provided. When two linear V-grooves are formed, the two linear V-grooves are located at the end of the side surface on which the linear V-groove is formed, and are located at 1/5 to 1/3 of the width of the side surface (20 to 33). The position of the range of %) is preferable, whereby the interval between the rolling roller rows accommodated in the two guide passages is wide, so that the bending (elastic deformation) in the width direction of the linear movement guide unit can be prevented. It is said that the torque load resistance in the width direction of the linear movement guide unit is improved. For example, in the linear movement guide unit 3 1 shown in Fig. 7, each of the linear V grooves is formed from the side where the linear V groove is formed. End face, located at the width of its side 24% of the position. The position of the linear V-groove represents the position where the depth of the straight V-groove is the largest (that is, the position of the apex of the V-groove.

The linear movement guiding device 50 of Fig. 16 is linearly movable, for example, on the base 56 with a plurality of, for example, two linear moving guide units 51, 52 of the present invention interposed therebetween. The slide table 57 is coupled to each other. The respective structures of the linear movement guide units 51 and 52 are the same as those shown in Fig. 7 except that the holding plates 16 for holding the rollers 15H and 15L shown in Fig. 1 are used. The configuration of the movement guide unit 31 is the same. One of the rod portions 51a of the linear movement guide unit 51 is fixed to the base 56, and the other rod portion 51b is fixed to the slide table 57. Similarly, one of the rod portions 52a of the linear movement guide unit 52 is fixed to the base 56, and the other rod portion 52b is fixed to the slide table 57. Linear movement guiding device 50. For example, assembled in the following order. First, the rod portion 51a of the linear movement guide unit 51 and the rod portion 52a of the linear movement guide unit 52 are fixed by screwing the bolts 59a screwed into the bolt holes 56a of the base 56, respectively. On the opposite sides of the base 56. Next, the slide table 57 is disposed on the linear movement guide units 51, 52. The bolts 59b are screwed into the respective through holes 57a of the slide table 57, and are fitted to the respective bolt holes 58b of the rod portions 51b and 51b. In this state, when the bolt 59c is screwed into the bolt hole 57b on the side surface of the slide table 57, the rod portion 51a of the guide unit 51 and the rod portion 51b and the rod portion of the linear movement guide unit 52 are linearly moved. The 52a and the rod portion 52b are fastened to each other and pressurized (preloading is applied). Thereby, the two rod portions of the linear movement guides and the plurality of rolling rollers disposed therebetween are brought into close contact without any gap. Finally, by tightening the bolts 59b, the rod portions 51b and 52b are fixed to the slide table -29 - 201206614 57. Fig. 17 is a view showing the configuration of the linear motion stage using the linear movement guide device 50 of Fig. 16. In the plan view of the example, Fig. 18 is a cross-sectional view of the linear movement stage 70 cut along the line III-III of the cutting line shown in Fig. 17. The linear motion stage 70 has a structure in which the lower surfaces of the platen 71 are supported by the plurality of (for example, four in total) linear movement guides 50 of Fig. 16 at intervals. Each of the linear movement guides 50 is disposed on a top surface of the support 73 that is erected on the base 72. The base 56 of each linear movement guide 50 is fixed to the stay 73, and the slide table 57 is fixed to the table 71. In order to linearly move the platen 71, a linear movement driving device 74 is provided on the base 72. The linear movement driving device 74 is composed of a motor 75 and a conveying screw 76. The conveying screw 76 is composed of a screw shaft 76a connected to a rotating shaft of the motor 75 and a nut 76b fitted around the motor. The linear movement driving device 74 is connected to the platen 71 by a nut seat 77 fixed around the nut of the conveying screw. When the rotation shaft of the motor 75 of the linear movement driving device 74 is rotated, the nut 7 6b of the conveying screw 76 is attached. It moves in the longitudinal direction of the screw shaft 76a. Thereby, the platen 71 connected to the nut 76b via the nut holder 77 is precisely directed to the linear movement guide assembled by the linear movement guides 50 together with the slide table 57 of each linear movement guide 50. The longitudinal direction of the rod portion of the lead-in unit (the left-right direction in FIGS. 17 and 18) is linearly moved, and the linear movement guides -30-201206614 that are supported by the platen 71 of the linear motion table 70 are assembled.

Therefore, for example, when the positioning of the article placed on the platen 71 is completed, and then the machining of the above article is to be performed, even if a very large load is applied to the platen 71 via the tool for machining, the article The position is also very difficult to change, and high-precision machining is possible. The linear moving table 7〇 (and the lifting table described later) not only performs machining on the positioned article, but also applies various loads to the positioned article to perform various inspections or pressurize other articles. It is particularly useful for the purpose of applying a large load to the platen 71 when the positioned articles are joined. Fig. 19 is a partially cutaway perspective view showing a configuration example of a lifting guide device using the linear movement guide unit of the present invention. The lifting guide 90 is configured to fix the rod portions 91a and 92a of one of the pair of linear movement guide units 91 and 92 arranged in the horizontal direction to the base 81 and the other rod portion 91b. '92b is fixed to the bottom surface (or side surface) of the wedge-shaped slide table 82 on which the inclined surface 82a is formed, and the wedge-shaped slide table 8 2 is coupled to the base 81 to linearly move the guide assembly 83 linearly movable in the horizontal direction; Through the rod portions 93a, 94a of each of the ones, there is an angle with respect to the horizontal direction. a pair of linear movement guiding units 93, 94 fixed to the inclined surface 82a of the wedge-shaped slide table 82 of the linear movement guide assembly 83; and a pair of linear movement guides 95, 96 are attached to the base by lifting and lowering The support base 84 that is erected on the table 81 is fixed to the other of the linear movement guide pair linear movement guide units 93 and 94 via the rod portions 93a and 94a of the respective side-31 - 201206614 to be fixed to the lift table 85. Composition. The linear movement guide units 91, 92, 93, and 94 are formed in the same manner as the linear movement guide shown in Fig. 7 except that the roller 15H plate 16 is used as shown in Fig. 10. The wedge-shaped slide table 82 can only move in a straight line; the rod portion moves in the longitudinal direction. That is, the opposite side of the wedge-shaped slide support table 84 advances or retreats. The wedge-shaped slide table 82 is connected to the same structure as that of the 17th linear motion drive unit 74 (not shown). The nut of the linear movement driving device is fixed to the bottom surface of the wedge slide table 82. The lifting table 8 5 can only move (lift) in the longitudinal direction of the straight moving guide. The straight slidable connection to the above-described wedge-shaped slide table 82, for example, causes the wedge-shaped slide table 82 to move forward together with the linearly moving rod portions 91b, 92b, and is simultaneously externally fixed to the linear movement guide of the wedge-shaped slide table 82. The portion 93a '94a is also advanced, and as a result, the lifting table 85 is connected to the rod portions 95b and 96b of the unit 1 of 95 and 96. When the detaching table 82 is retracted together with the linear movement guiding units 91 and 92, the linear movement guide unit 93, the one of the rod portions 93b and 94b of the aligning assembly 83, the structures of 95 and 96, and the holding of the 15L are maintained.

As a result, the elevating table 85 rises together with the rod portions 95b and 96b of the linear movement guide units 95 and 96. Fig. 20 is a plan view showing a configuration example of the elevating table using the elevating guide device 9 of Fig. 19, 21 is a cross-sectional view of the elevating table 1〇0 cut along the line IV-IV of the cutting line shown in Fig. 20. The elevating table 100 has a plurality of (for example, four in total) lifting guides in Fig. 19 The guiding device 90 has a structure in which the lower surfaces of the platens 1〇1 are supported at intervals from each other. The device 90 is disposed on a top surface of the pillar 103 that is erected on the base 1〇2. The base 81' of each lifting guide 90 is fixed to the pillar 103' and the lifting platform 85 is fixed to the pallet 1〇1 In addition, the opening portion 1a of the table 101 may be provided in accordance with the use of the lifting platform 100, and the lifting table 85' of each of the lifting and lowering guides 90 of the lifting platform 100 may be raised at an equal distance, for example. The plate 1 〇1 is raised. Conversely, by lowering the lifting table 85 of each of the lifting and lowering guides 90, for example, at an equal distance, the platen 1 0 1 can be lowered. By individual setting: the lifting table 1〇〇 The lifting or lowering of the lifting platform 85 of each of the lifting and lowering guides 90 can also adjust the level of the table ι. 1. When the surface of the lifting table 85 of each of the lifting and lowering guides 90 is arranged in the vertical direction, they are different from each other. In the position, the platen 101 is slightly elastically deformed. If it is necessary to prevent the elastic deformation of the platen 1 〇1, for example, a conventionally known between the platen 101 and the lifting platform 85 of each of the lifting guides 90 may be provided.
