201017141 計測作業耗費工夫和時間的問題。 本發明係鑑於上述情事而硏發者，其目的在於提供旋 轉體的平衡調整方法、旋轉體及具備該旋轉體的馬達，以 使藉由熱變形而緊緊地嵌合組裝成之旋轉軸和被組裝構件 所構成的旋轉體長期地產生之不平衡，可容易且正確地獲 得調整。 • 【實施方式】 爲了達成上述課題，本發明提出以下手段。即，本發 明係使大致圓盤狀的被組裝構件藉由溫度變形而緊緊地嵌 合在旋轉軸所構成的旋轉體的平衡調整方法，其係預先設 定平衡調整位置的軸周圍位置，使前述旋轉體因爲緊緊地 嵌合而產生的變形之變形方向和來自前述旋轉軸中心的方 向進行對應，且進行長期的平衡調整時，在該平衡調整位 置進行重量調整。 ® 藉由有關本發明之旋轉體的平衡調整方法，在旋轉體 ，將平衡調整位置設定成成爲：藉由因溫度變形而緊緊地 嵌合所產生的變形之變形方向、和來自旋轉軸中心的方向 所相對應之軸周圍的位置。此處，旋轉體之長期的不平衡 係產生在與緊緊地嵌合所造成的變形方向相對應之方向。 因此，進行長期的平衡調整時，藉由在預先設定的平衡調 整位置進行重量調整的方式，可消除長期地產生之不平衡 。其結果可省略以往必要的另外藉由振動分析器等，檢測 平衡調整位置及方向之作業，而僅進行調整重量大小即可 201017141 ，故可容易、正確且在短時間進行該平衡調整。 又，上述旋轉體的平衡調整方法中，於前述旋轉體設 置在軸周圍呈非對稱之非對稱部亦可。 根據本發明之旋轉體的平衡調整方法，藉由在旋轉體 設置非對稱部的方式，旋轉體係將從旋轉軸中心朝向非對 稱部的方向之對應方向作爲變形方向，進行變形。因此， 可使平衡調整位置對應於設有非對稱部的軸周圍的位置而 進行設定。 ⑩ 又，上述旋轉體的平衡調整方法中，進行前述旋轉體 的初期平衡調整時，以較最適當的平衡所必需之重量的變 化量更大的變化量進行調整亦可。 根據本發明之旋轉體的平衡調整方法，藉由以較初期 平衡調整的最適當平衡所必需之重量的變化量更大的變化 量，設定重量的方式，可在長期地產生不平衡的方向之相 反方向設定平衡，藉此可延長在該旋轉體長期地產生不平 衡以致必須進行維護的期間，可使該旋轉體經過長期地安 參 定地運用。 又，上述旋轉體的平衡調整方法中，進行前述長期的 平衡調整時，進行前述旋轉體的加速度計測或振動計測， 根據由該計測所獲得的該旋轉體的加速度位準或振動位準 ’而決定在前述平衡調整位置的重量大小。 根據本發明之旋轉體的平衡調整方法，以藉由計測獲 得旋轉體產生的振動之加速度位準或振動位準的方式，可 根據該等而容易、正確且在短時間求出用於調整平衡的重 -8 - 201017141 量，進行平衡調整。 又，本發明之旋轉體具備旋轉軸、和藉由溫度變形而 緊緊地嵌合安裝在該旋轉軸之大致圓盤狀的被組裝構件， 在前述旋轉軸及前述被組裝構件的至少另一方面，於緊緊 地嵌合所產生的變形之變形方向、和來自前述旋轉軸中心 的方向所相對應之軸周圍的位置，設有進行重量調整的平 衡調整位置，以便調整長期地變化之全體平衡。 φ 根據本發明之旋轉體，在旋轉軸或被組裝構件的至少 另一方面，將平衡調整位置設在：藉由溫度變形而緊緊地 嵌合所產生的變形之變形方向、和來自旋轉軸中心的方向 所相對應之軸周圍的位置。此處，旋轉體的長期不平衡係 產生在與緊緊地嵌合所造成的變形方向之相對應方向。因 此，進行長期的平衡調整時，藉由在預先設定的平衡調整 位置進行重量調整的方式，可消除長期地產生之不平衡。 其結果可省略以往必要的另外藉由振動分析器等，檢測平 〇 衡調整位置及方向之作業，而僅進行調整重量大小即可， 故可容易、正確且在短時間進行該平衡調整。 又，在上述旋轉體，前述旋轉軸或前述被組裝構件亦 可在軸周圍具有呈非對稱之非對稱部。 根據本發明之旋轉體，以在旋轉體或被組裝構件具有 非對稱部的方式，從旋轉軸中心朝與朝向非對稱部的方向 相對應的方向變形而產生不平衡。因此’可在對應於設有 非對稱部的軸周圍的位置進行平衡調整位置之設定。 又，在上述旋轉體，於前述旋轉軸或前述被組裝構件 -9 - 201017141 的至少另一方面，作爲前述初期平衡調整，亦可以較最適 當的平衡所需之重量的變化量更大的變化量進行調整。 根據本發明之旋轉體，藉由以較初期平衡調整的最適 當平衡所必需之重量的變化量更大的變化量，設定重量的 方式’可在長期地產生不平衡的方向之相反方向設定平衡 ’藉此可延長在該旋轉體長期地產生不平衡以致必須進行 維護的期間，而可經過長期地安定地運用。[0015] 又，在上述旋轉體，亦可具有：檢測手段，用於進行 前述旋轉軸的加速度計測或振動計測；及運算手段，係根 據由該檢測手段之計測所獲得的前述旋轉體的加速度位準 或振動位準，進行運算而決定在前述平衡調整位置進行調 整的重量大小。 根據本發明之旋轉體，以藉由計測獲得旋轉軸產生的 振動之加速度位準或振動位準的方式，可根據該等而容易 、正確且在短時間求出用於調整平衡的重量，進行平衡調 整 。 又，本發明之馬達亦可於旋轉體的旋轉軸配設作爲被 組裝構件之旋轉元件，於該旋轉元件的外側配置固定元件 且使其成爲與前述旋轉體同軸。 本根據發明，作爲旋轉體的被組裝構件而配設旋轉元 件，藉由在該旋轉元件的外側配設固定元件且使其成爲與 該旋轉體同軸的方式構成馬達，因此藉由在如上述之平衡 調整位置的重量調整，可較以往容易、正確且在短時間進 行該馬達之維修。 -10- 201017141 根據本發明之旋轉體的平衡調整方法，由於將來自旋 轉軸的方向與旋轉體的變形方向相對應之軸周圍的位置作 爲平衡調整位置，進行重量調整，所以在藉由熱變形而緊 緊地嵌合所組裝成的旋轉軸和被組裝構件所構成的旋轉體 ，長期地產生之不平衡，可獲得容易且正確地調整。 根據本發明之旋轉體，由於可將來自旋轉軸的方向與 變形方向相對應之軸周圍的位置作爲平衡調整位置，進行 ❹ 重量調整，因此在藉由熱變形而緊緊地嵌合所組裝成的旋 轉軸和被組裝構件，長期地產生之不平衡，可獲得容易且 正確地調整。 (第1實施形態） 參照第1圖〜第3圖，説明關於本發明之第1實施形 態的旋轉體的平衡調整方法、及適用該平衡調整方法的旋 轉體。在第1圖及第2圖以符號1所示之旋轉體，係例如 © 適用於作爲馬達100的内部旋轉體者，該旋轉體係由轉子 5(旋轉軸）和電樞6(被組裝構件）所構成，該轉子5(旋轉軸 )係於外殼2的開口部透過軸承3及軸承4而旋轉自如地 被支撐著，該電樞6(被組裝構件）係於外殼2内且設在位 於軸承3及軸承4之間的轉子5的周面的旋轉元件。 電樞6係由在積層鋼板捲繞對應極數之電樞捲線的方 式所構成，該積層鋼板係鋼板以滾筒狀層積複數層所構成 ，且係全體形狀形成爲大致圓盤狀的被組裝構件，形成非 對稱部8的鍵8A是被中介作爲制動構件，且固定在該轉 -11 - 201017141 子5的周面。使鍵8A中介後，藉由利用加熱及冷卻造成 之溫度變形之熱壓（緊緊地嵌合），將該電樞6固定於轉子 5的外周面。 該鍵8A係藉由嵌合在形成於電樞6内周面的凹部6A 、和形成在轉子5外周面的鍵溝5A的方式，將電樞6固 定在沿著轉子5的周方向之位置。又，該鍵8A被形成爲 在轉子5的軸周圍配置1處之非對稱狀態，藉此使轉子5 及電樞6配合熱變化而朝形成軸直角方向之預定變形方向 P變形。即，藉由構成非對稱部8的鍵8A、鍵溝5A及凹 部6A，轉子5及電樞6係從轉子5的中心軸（彳），朝與朝 向非對稱部8的方向相對應之大致相差180度的變形方向 P，藉由熱變形進行變形。然後，轉子5及電樞6所構成 的旋轉體1，係於與該變形方向P相對應的位置進行初期 平衡調整，作爲製品出貨。更具體而言，本實施形態中， 在來自中心軸（彳）的方向和變形方向P成爲相反側之位置 ，亦即非對稱部8和中心軸（〇周圍的位置大致一致的初期 平衡位置13，藉由設置配重12用以附加重量的方式，謀 求全體之平衡調整。此外，初期平衡調整係亦可將與上述 初期平衡位置1 3在中心軸（〇周圍相反側的位置作爲初期 平衡位置，藉由減少重量的方式進行。 然後，藉由重量調整進行調整長期地產生之不平衡的 平衡調整位置9，係與該變形方向P相對應，於本實施形 態中，設在來自中心軸（彳）的方向和變形方向P在中心軸（〆 )周圍成爲大致180度相反方向的位置，亦即設在非對稱 201017141 部8和在中心軸（彳）周圍一致的位置。其結果，對於長期的 不平衡，不須藉由不平衡計測裝置等調查平衡位置，而僅 在平衡調整位置9調整重量，即可進行旋轉體1全體的平 衡調整。此外，針對平衡調整位置9，也僅以重量的加減 不同，設定在來自中心軸（4)的方向和變形方向P大致一 致的位置者亦可。亦即，作爲平衡調整位置9，係以來自 中心軸（彳）的方向對於變形方向P，在中心軸（彳）周圍如上 φ 述般地成爲〇度或180度的方向之方式，被設定在與變形 方向p相對應的位置。 又，本實施形態中，平衡調整位置9特別被設定在設 於轉子5的端部之耦合件10。該耦合件10係設在突出於 外殼2的外部之轉子5的端部，用於與被驅動體11連結 者。然後，藉由這種將平衡調整位置9設在外殼2的外部 之耦合件10的方式，在平衡調整時不須分解旋轉體1，可 容易地進行平衡調整。 β 另一方面，在與電樞6相對向的外殼2的内周面，設 有由磁鐵構成的固定元件12。又，在外殼2内的側部設有 換向器’其係供電至電樞6’在形成於固定元件12間的磁 場内使轉子5產生旋轉力’但圖示中被省略。然後，以在 上述旋轉體1加上固定元件12、耦合件1〇及換向器（省略 圖示）的方式，構成馬達100。 此外’本實施形態中，藉由鍵8Α、鍵溝5Α及凹部 6Α構成的非對稱部8，係設在轉子5和電樞6之間，但設 在該等轉子5或電樞6的其中一方亦可。 -13- 201017141 接著’根據第3圖説明有關本實施形態之旋轉體1的 平衡調整方法。第3圖係顯示不平衡量及其方向之圖表， 顯示有複數之實施例。 如第3圖中以符號]vil所示之複數的黑色圓，當導入 熱壓組裝旋轉體1作爲馬達1〇〇出貨時，進行初期平衡調 整’將不平衡量設定爲容許値以下。具體而言，在初期平 衡位置13，以進行重量調整的方式，消除因熱壓造成的熱 變形所產生的不平衡，不平衡量被設定爲第3圖所示之同 心圓之中最内側的圓内。此外，初期平衡調整亦可在與平 衡調整位置9相同的位置進行。 另一方面，在馬達100的運轉開始後，因爲長期的變 化’在旋轉體1產生變形。此時，旋轉體1因非對稱部8 而朝變形方向P變形。 因此，如第3圖中符號A、B、C所示之白色空心三 角，在開始運轉1年後，形成沿著變形方向P產生大的不 平衡。 然後，在運轉開始後的維護作業，如第1圖所示’僅 以在對應變形方向P所被設定的平衡調整位置9進行重量 調整，即可對從先前的變形產生的不平衡進行平衡調整。 其結果可省略如以往以測定機器檢測平衡調整位置9等之 作業，而可容易且正確地在短時間進行該平衡調整。 此外，在平衡調整位置9進行轉子5的重量平衡調整 之作業，例如對轉子5直接地進行増加重量等處理亦可。 但是，在轉子5，以在位於外殼2外側的顆合件10設定調 201017141 整平衡調整位置9的方式，不需要取下外殼2等的功夫， 即可進行平衡調整。再者’將與平衡調整位置9對應的位 置作爲賴合件10中的固定位置，藉由變更在該固定位置 使用的螺栓、墊片的重量之方式進行調整亦可。藉由這種 方式’不需要重新準備用於増加重量的構件，也不需要其 固定用之構造，可將零件件數減少至最少限度。又，轉子 5的平衡調整作業除了平衡調整位置9以外，也可在軸周 Φ 圍將相差±90°的位置作爲平衡調整位置進行。藉由這種方 式，對朝變形方向P之變形成分、和藉由與變形方向P正 交的變形成分所產生的不平衡，皆可進行平衡調整。進而 也可改變平衡調整位置9，而將平衡調整位置9的180度 相反側之位置作爲平衡調整位置。於該情形下，改變在平 衡調整位置9的重量加重或減輕，而以將重量減輕或加重 的方式調整即可。 如以上詳細説明，關於本實施形態之旋轉體1的平衡 ® 調整方法、及適用該平衡調整方法的旋轉體1，係藉由溫 度變形產生的緊緊地嵌合，從中心軸（彳）朝形成朝向軸周圍 的預定位置之軸直角方向的變形方向P產生變形，在初期 狀態下，將因此產生的不平衡藉由在初期平衡位置1 3之 重量調整而予以消除。又，在與該初期平衡位置13對應 的中心軸（彳）周圍的位置設定平衡調整位置9，用以調整長 期的不平衡。因此，產生長期的不平衡時，可藉由在平衡 調整位置9進行重量調整的方式，消除長期地產生之不平 衡。其結果可省略以往必要的另外藉由振動分析器等，檢 -15- 201017141 測平衡調整位置及方向之作業，而僅進行調整重量大小即 可，故可容易、正確且在短時間進行該平衡調整。 (第2實施形態） 參照第4A圖、第4B圖及第5圖，説明關於本發明之 第2實施形態的旋轉體20的平衡調整方法、及適用該平 衡調整方法的旋轉體20。第2實施形態所示之旋轉體的平 衡調整方法相異於第1實施形態之平衡調整方法之處，係 @ 如第4Α圖及第4Β圖所示，在進行初期平衡調整時，將 設在初期平衡位置22(平衡調整位置）的配重21的重量， 設定成長期地予測到轉子5的不平衡的重量。此外，變形 方向Ρ和非對稱部8、初期平衡位置22、平衡調整位置9 各個之關係是與第1實施形態相同，因此省略説明。 配重21係爲了在熱壓導入時修正在變形方向Ρ產生 的不平衡而被配置，如第1實施形態的初期平衡調整後的 符號M2所示之黑色圓，不僅是改變必要最小限度的重量 〇 使其包含於容許値内，尙以較不平衡量爲零之最適當的平 衡所必需之重量的變化量更大的變化量之重量進行調整， 使不平衡量移行到第5圖以符號M3所示之白色圓的位置 〇 即，通常配重21是爲了修正在導入時因非對稱部8 而在中心軸（彳）的相反側產生的不平衡（在第5圖以符號M2 表示的黑色圓）而設者，但本實施形態中，經過長期使用 後，如第5圖以符號23 Α〜23C所示之白色空心三角，預 -16- 201017141 測軸方向直角的變形產生在軸周圍的變形方向p，在初期 平衡位置22以較必需的重量的變化量更大的變化量，預 先進行了旋轉體20的初期平衡調整。更具體而言，旋轉 體20係以藉由溫度變形造成緊緊地嵌合而在轉子5的軸 周圍形成非對稱部8之方式，在挾持著轉子5的中心軸（4) 而位於非對稱部8的相反側之變形方向P，預先設定成使 轉子5長期地產生變形。然後，進一步先預測這種在非對 φ 稱部8的相反側產生的轉子5的變形長期地増大之情形（ 在第4A圖及第4B圖以符號23顯示，在第5圖以符號 2 3 A〜23C顯示），將設置在用於調整該變形的初期平衡位 置22内的配重21的重量，設定爲較必要的重量更重。 如以上詳細地説明，關於第2實施形態之旋轉體20 的平衡調整方法、及適用該平衡調整方法的旋轉體20,係 將在初期平衡調整時設置於初期平衡位置22的配重21的 重量，設定爲較形成最適當平衡所必需之重量的變化量更 大的變化量，藉此如符號23 A〜23C所示，可在成爲長期 地產生變形之變形方向P的相反方向之位置調整平衡，藉 此可延長在該旋轉體20的變形方向P產生不平衡而必須 進行維護的期間，可使該旋轉體1經過長期安定地運用。 此外，本實施形態中，設定成將來自中心軸（彳）的方向 和變形方向P在中心軸（彳）周圍成爲相反側的位置作爲初 期平衡位置22設置配重21’但不限定於此。如此地在來 自中心軸（彳）的方向和變形方向P在中心軸（彳）周圍成爲相 反側的位置將重量加重，進行初期平衡調整時’與第1實 -17- 201017141 施形態同樣地，也可在來自中心軸（彳）的方向和變形方向P 在中心軸（彳）周圍大致一致的位置將重量減輕，於該情形下 ，以較必要的重量更輕的方式進行初期平衡調整即可。又 ，進行初期平衡調整的位置只要是與變形方向P在軸周圍 相對應的位置，無論是與隨著長期的變化用於進行平衡調 整的平衡調整位置在軸方向相異的位置或相同的位置皆可 (第3實施形態） 參照第6圖及第7圖，説明關於本發明之第3實施形 態的旋轉體30的平衡調整方法、及適用該平衡調整方法 的旋轉體30。第3實施形態所示之旋轉體的平衡調整方法 相異於先前的實施形態的平衡調整方法之處，係如第6圖 及第7圖所示，在轉子5的附近，配置用於檢測該轉子5 的加速度的檢測手段亦即加速度檢測器31或用於檢測該 轉子5的振動之振動檢測器32、和用於運算平衡調整所必 @ 需的重量大小之運算手段33,根據來自該等加速度檢測器 31或振動檢測器32所輸出之檢測訊號，進行在對應於變 形方向P的平衡調整位置9之平衡調整。 加速度檢測器3 1或振動檢測器32的檢測訊號，係輸 入於符號33所示之運算手段。然後，在該運算手段33， 於檢測手段爲加速度檢測器31的情形下，以在該加速度 檢測器3 1檢測到的轉子5的加速度位準，乘上相對應之 影響係數的方式，決定在平衡調整位置9之平衡調整重量 -18- 201017141 。同樣地，檢測手段爲振動檢測器32的情形下，以在該 振動檢測器3 2檢測到的轉子5的振動位準，乘上相對應 之影響係數的方式，決定在平衡調整位置9之平衡調整重 量。此外’設定在該運算手段33的影響係數，係表示藉 由因產生不平衡的情形所產生的振動而被檢測到的加速度 位準或振動位準、和爲了對於該不平衡進行平衡調整所必 需的重量大小之關係的係數。然後，影響係數係藉由預先 〇 調査加速度位準或振動位準、和消除不平衡所必需的重量 之相關關係而決定。 如以上詳細地説明’關於第3實施形態之旋轉體30 的平衡調整方法、及適用該平衡調整方法的旋轉體30，係 於平衡調整時，進行旋轉體3 0的加速度計測或振動計測 ’根ii藉由該計測所獲得的該旋轉體的加速度位準或振動 位準，在前述平衡調整位置9決定重量大小。 然後’以藉由計測，獲得在旋轉體3 0產生的振動之 ® 加速度位準或振動位準的方式，根據該等而容易、正確且 在短時間求出平衡調整所需的重量，而可進行平衡調整。 以上’參照圖面詳述了本發明之實施形態，但具體的 構成並不受限於本實施形態，不超出本發明之要旨的範圍 之設計變更等亦包含在內。 此外’上述各實施形態中，在旋轉體1、20、30設置 非對稱部8 ’將與非對稱部8對應的軸周圍的位置作爲初 期平衡位置’且設定作爲預先平衡調整位置，但也可以是 沒有非對稱部8之構造。這種構造也在預定的初期平衡位 -19 -

TECHNOLOGICAL FIELD OF THE INVENTION The present invention relates to a motor, a generator, a sleeve, or the like for correcting a rotation formed by tightly fitting a rotating shaft by temperature deformation. The technique of body imbalance. The present application claims priority based on Japanese Patent Application No. 2008-222783, filed on Jan. 29,,,,,,,,,, [Prior Art] A rotating body having a hot pressing portion such as a motor or a generator is usually assembled in an axisymmetric structure. However, such a rotating body is not easy to form an equal locking in the circumferential direction at the assembly stage, so that slight shaft bending and unevenness are generated. Then, in order to correct this imbalance, it will be adjusted at the shipping stage 〇 (initial balance adjustment) to minimize the vibration during the introduction. A device for measuring such an imbalance is known as the technique disclosed in Japanese Patent Publication 1. The unbalanced measuring method and apparatus therefor shown in Patent Document 1 include an angle detector for detecting an angle with respect to a rotation axis coupled to a rotating shaft of the test body, and a vibration sensor (Pick up). For detecting periodic unbalanced vibration acting on the rotating shaft, the unbalanced vibration system is accompanied by a rotational motion around the axis of rotation of the test body, ie, the composite rotating body; according to the output from the angle detector and the vibration sensor, Calculate the maximum unbalanced orientation of each rotating body and the amount of imbalance in its orientation. -5- 201017141 Then, based on the unbalance amount, an operation of balancing the rotating shaft is performed. Specifically, as shown in FIGS. 8 and 9, the rotating shaft 51 of the armature 50 as the member to be assembled is heat-pressed, and is configured to detect the periodic unbalanced vibration acting on the rotating shaft 51. The vibration detector 52A of the vibration analyzer 52 calculates the maximum unbalanced azimuth of the rotating shaft 51 and the amount of unbalance in the azimuth thereof by the arithmetic means 53 based on the output from the vibration analyzer 52. Then, the balance operation of the rotating shaft is performed based on the unbalance amount.

The cause of this long-term imbalance is considered to be the state of stress from the time of superheating, and the stress state is gradually changed by minute sliding or the like, and the bending state of the rotor is also gradually changed. Therefore, when the vibration level becomes high and the tolerance is not satisfied, the imbalance must be appropriately corrected according to the measurement of the vibration measurement device. Further, in the above-described rotating body, the initial rotor bending is dependent on the hot pressing state, and the bending direction of the rotor is not necessarily required. Therefore, the balancing operation must be periodically performed by the unbalance measuring device described in Patent Document 1. However, in the above-mentioned Patent Document 1, it is possible to grasp the unbalanced direction of each of the rotating bodies based on the outputs from the angle detectors and the vibration sensors, etc. The problem of measuring the work time and time is -6 - 201017141. The present invention has been made in view of the above circumstances, and an object thereof is to provide a method for adjusting a balance of a rotating body, a rotating body, and a motor including the rotating body, so that the rotating shaft is tightly fitted and assembled by thermal deformation. The rotating body composed of the assembled member is unbalanced for a long period of time, and can be easily and accurately adjusted. [Embodiment] In order to achieve the above object, the present invention proposes the following means. In other words, the present invention is a method for adjusting the balance of a rotating body formed by rotating a shaft in a substantially disk-shaped assembled member by temperature deformation, and the position around the shaft of the balance adjustment position is set in advance so that the position is adjusted. The deformation direction of the deformation due to the tight fitting of the rotating body corresponds to the direction from the center of the rotation axis, and when the balance adjustment is performed for a long period of time, the weight adjustment is performed at the balance adjustment position. According to the balance adjustment method of the rotating body according to the present invention, the balance adjustment position is set in the rotating body to be a deformation direction by deformation which is tightly fitted by temperature deformation, and from the center of the rotation axis The direction of the axis corresponding to the direction. Here, the long-term imbalance of the rotating body is generated in a direction corresponding to the direction of deformation caused by the tight fitting. Therefore, when the balance adjustment is performed for a long period of time, the imbalance generated in the long-term can be eliminated by performing the weight adjustment at the preset balance adjustment position. As a result, the operation of detecting the balance adjustment position and direction by the vibration analyzer or the like, which is necessary in the past, can be omitted, and only the weight adjustment can be performed 201017141, so that the balance adjustment can be performed easily, accurately, and in a short time. Further, in the above-described method for adjusting the balance of the rotating body, the rotating body may be provided in an asymmetrical asymmetric portion around the shaft. According to the balance adjusting method of the rotating body of the present invention, the rotating system is deformed by providing the asymmetrical portion in the rotating body from the direction corresponding to the direction of the axis of the rotating shaft toward the non-symmetric portion. Therefore, the balance adjustment position can be set corresponding to the position around the shaft provided with the asymmetrical portion. Further, in the balance adjusting method of the rotating body, when the initial balance adjustment of the rotating body is performed, the amount of change in the weight necessary for the most appropriate balance may be adjusted. According to the balance adjusting method of the rotating body of the present invention, by setting the weight by a larger amount of change in the weight necessary for the most appropriate balance adjusted at the initial balance, the unbalanced direction can be generated for a long period of time. The balance is set in the opposite direction, whereby the rotating body can be used for a long period of time while the rotor is unbalanced for a long period of time so that maintenance must be performed. Further, in the balance adjustment method of the rotating body, when the long-term balance adjustment is performed, the acceleration measurement or the vibration measurement of the rotating body is performed, and based on the acceleration level or the vibration level of the rotating body obtained by the measurement. Determine the weight of the balance adjustment position. According to the method for adjusting the balance of the rotating body of the present invention, the acceleration level or the vibration level of the vibration generated by the rotating body can be obtained by measurement, and the balance can be easily and correctly determined in a short time according to the above. The weight of -8 - 201017141, balance adjustment. Further, the rotating body according to the present invention includes a rotating shaft and a substantially disk-shaped assembled member that is tightly fitted to the rotating shaft by temperature deformation, and at least one of the rotating shaft and the assembled member On the other hand, in the direction of the deformation of the deformation generated by the tight fitting and the position around the shaft corresponding to the direction from the center of the rotation axis, a balance adjustment position for weight adjustment is provided to adjust the entire length of the change. balance. φ According to the rotating body of the present invention, at least another aspect of the rotating shaft or the assembled member, the balance adjusting position is set to: a deformation direction of the deformation generated by tight fitting by temperature deformation, and a rotation axis from the rotating shaft The position around the axis corresponding to the direction of the center. Here, the long-term unbalance of the rotating body is generated in a direction corresponding to the direction of deformation caused by tight fitting. Therefore, when performing long-term balance adjustment, the weight adjustment can be performed at a preset balance adjustment position, thereby eliminating the imbalance generated over a long period of time. As a result, it is possible to omit the operation of adjusting the position and direction of the balance by a vibration analyzer or the like, and to adjust the weight only, so that the balance adjustment can be performed easily, accurately, and in a short time. Further, in the above-described rotating body, the rotating shaft or the member to be assembled may have an asymmetrical portion around the shaft. According to the rotating body of the present invention, the rotating body or the assembled member has an asymmetrical portion, and is deformed from the center of the rotating shaft toward a direction corresponding to the direction toward the asymmetrical portion to cause an imbalance. Therefore, the setting of the balance adjustment position can be performed at a position corresponding to the periphery of the shaft provided with the asymmetrical portion. Further, in the above-described rotating body, at least the other of the rotating shaft or the assembled member -9 - 201017141, the initial balance adjustment may be changed more than the amount of change required for the most appropriate balance. The amount is adjusted. According to the rotating body of the present invention, the weight setting method can be set in the opposite direction to the direction in which the imbalance is generated for a long period of time by a larger amount of change in the weight necessary for the most appropriate balance adjusted at the initial balance. 'This makes it possible to extend the period in which the rotating body is unbalanced for a long period of time so that maintenance must be performed, and it can be used stably for a long period of time. [0015] Further, the rotating body may include: detecting means for performing acceleration measurement or vibration measurement of the rotating shaft; and calculating means for accelerating the rotating body obtained by measuring by the detecting means The level of the position or the vibration level is calculated to determine the weight to be adjusted at the balance adjustment position. According to the rotating body of the present invention, the weight for adjusting the balance can be easily and correctly obtained in a short time by measuring the acceleration level or the vibration level of the vibration generated by the rotating shaft. Balance adjustment. Further, in the motor of the present invention, a rotating element as a member to be assembled may be disposed on a rotating shaft of the rotating body, and a fixing element may be disposed outside the rotating element so as to be coaxial with the rotating body. According to the invention, the rotating element is disposed as the member to be assembled of the rotating body, and the fixed element is disposed outside the rotating element and the motor is configured to be coaxial with the rotating body. The weight adjustment of the balance adjustment position makes it easier, correct and short-term maintenance of the motor. -10-201017141 According to the method for adjusting the balance of the rotating body of the present invention, since the position around the shaft corresponding to the direction of the rotation of the rotating body is used as the balance adjustment position, the weight is adjusted, so that the heat is deformed. Further, the rotating shaft formed by the assembled rotating shaft and the assembled member can be tightly fitted for a long period of time, and can be easily and accurately adjusted. According to the rotary body of the present invention, since the position around the shaft corresponding to the direction of the rotation axis and the direction of the deformation can be used as the balance adjustment position, the weight adjustment is performed, and therefore, the assembly is tightly fitted by thermal deformation. The rotation axis and the assembled member are unbalanced for a long period of time, and can be easily and correctly adjusted. (First Embodiment) A method of adjusting the balance of the rotating body according to the first embodiment of the present invention and a rotating body to which the balance adjusting method is applied will be described with reference to Figs. 1 to 3 . The rotating body shown by reference numeral 1 in Figs. 1 and 2 is, for example, applied to an internal rotating body of the motor 100, which is composed of a rotor 5 (rotating shaft) and an armature 6 (assembled member). In this configuration, the rotor 5 (rotating shaft) is rotatably supported by the opening of the casing 2 through the bearing 3 and the bearing 4, and the armature 6 (assembled member) is housed in the casing 2 and is disposed at the bearing. 3 and a rotating element of the circumferential surface of the rotor 5 between the bearings 4. The armature 6 is formed by winding a corresponding number of armature windings on a laminated steel sheet, and the laminated steel sheet-like steel sheet is formed by laminating a plurality of layers in a roll shape, and is formed into a substantially disk shape as a whole. The member, the key 8A forming the asymmetrical portion 8, is interposed as a brake member, and is fixed to the circumferential surface of the turn -11 - 201017141 sub 5 . After the key 8A is interposed, the armature 6 is fixed to the outer circumferential surface of the rotor 5 by hot pressing (tight fitting) by temperature deformation by heating and cooling. The key 8A fixes the armature 6 in the circumferential direction of the rotor 5 by fitting the recessed portion 6A formed on the inner peripheral surface of the armature 6 and the key groove 5A formed on the outer peripheral surface of the rotor 5. . Further, the key 8A is formed in an asymmetrical state in which one portion is disposed around the axis of the rotor 5, whereby the rotor 5 and the armature 6 are thermally deformed to be deformed in a predetermined deformation direction P in the direction perpendicular to the axis. That is, the rotor 5 and the armature 6 are formed from the central axis (彳) of the rotor 5 toward the direction toward the asymmetric portion 8 by the key 8A, the key groove 5A, and the recessed portion 6A constituting the asymmetric portion 8. The deformation direction P which is different by 180 degrees is deformed by thermal deformation. Then, the rotor 1 composed of the rotor 5 and the armature 6 is initially balanced and adjusted at a position corresponding to the deformation direction P, and is shipped as a product. More specifically, in the present embodiment, the direction from the central axis (彳) and the direction of the deformation direction P are opposite to each other, that is, the asymmetrical portion 8 and the central axis (the initial equilibrium position 13 in which the positions around the crucible substantially coincide with each other) The balance adjustment is performed by providing the weight 12 for adding the weight. The initial balance adjustment system may also be the initial balance position on the center axis (the opposite side of the circumference) from the initial balance position 13 Then, the weight is adjusted by reducing the weight. Then, the imbalance adjustment position 9 which is adjusted by the weight adjustment for a long period of time is associated with the deformation direction P. In the present embodiment, it is provided from the central axis ( The direction and the deformation direction P of the 彳) are approximately 180 degrees opposite to each other around the central axis (〆), that is, the position of the asymmetric 201017141 portion 8 and the center axis (彳). The result is long-term. The imbalance is not required to investigate the balance position by the unbalance measuring device, but the weight can be adjusted only at the balance adjustment position 9, and the entire rotating body 1 can be performed. In addition, the balance adjustment position 9 may be set to a position where the direction from the central axis (4) and the deformation direction P substantially coincide with each other only by the addition or subtraction of the weight. That is, as the balance adjustment position 9, The direction from the central axis (彳) is set to a position corresponding to the deformation direction p in such a manner that the deformation direction P is in the direction of the twist or 180 degrees around the central axis (彳) as described above. Further, in the present embodiment, the balance adjustment position 9 is particularly set in the coupling member 10 provided at the end of the rotor 5. The coupling member 10 is provided at the end of the rotor 5 which protrudes from the outside of the outer casing 2 for Then, by the coupling member 10 which sets the balance adjustment position 9 to the outside of the casing 2, it is possible to easily perform balance adjustment without decomposing the rotating body 1 at the time of balance adjustment. On the other hand, a fixing member 12 made of a magnet is provided on the inner peripheral surface of the outer casing 2 opposed to the armature 6. Further, a commutator is provided on the side inside the outer casing 2, which supplies power to the armature. 6' is formed on the fixing member 12 The rotor 5 generates a rotational force in the magnetic field, but is omitted in the drawing. Then, the motor 100 is configured such that the fixed element 12, the coupling 1〇, and the commutator (not shown) are added to the rotating body 1 described above. Further, in the present embodiment, the asymmetrical portion 8 composed of the key 8Α, the key groove 5Α, and the recessed portion 6Α is provided between the rotor 5 and the armature 6, but is provided in the rotor 5 or the armature 6. In addition, the method of adjusting the balance of the rotating body 1 according to the present embodiment will be described with reference to Fig. 3. Fig. 3 is a graph showing the amount of unbalance and its direction, and shows a plurality of embodiments. In the three-figure black circle indicated by the symbol vil in FIG. 3, when the hot-press assembly rotating body 1 is introduced as the motor 1 ,, the initial balance adjustment is performed, and the unbalance amount is set to be allowable 値 or less. Specifically, at the initial balance position 13, the imbalance caused by the thermal deformation due to the hot pressing is eliminated so that the weight is adjusted, and the unbalance amount is set to the innermost circle among the concentric circles shown in FIG. Inside. Further, the initial balance adjustment can also be performed at the same position as the balance adjustment position 9. On the other hand, after the start of the operation of the motor 100, deformation occurs in the rotating body 1 due to long-term changes. At this time, the rotating body 1 is deformed in the deformation direction P by the asymmetrical portion 8. Therefore, as shown by the white hollow triangles shown by the symbols A, B, and C in Fig. 3, a large imbalance occurs along the deformation direction P after one year of starting the operation. Then, as shown in Fig. 1, the maintenance work after the start of the operation is adjusted only by the weight adjustment position 9 set in the corresponding deformation direction P, so that the imbalance caused by the previous deformation can be balanced. . As a result, the operation of detecting the balance adjustment position 9 by the measuring device can be omitted, and the balance adjustment can be easily and accurately performed in a short time. Further, in the operation of adjusting the weight balance of the rotor 5 at the balance adjustment position 9, for example, the rotor 5 may be directly subjected to a treatment such as weighting. However, in the rotor 5, the balance adjustment position 9 of the 201017141 is set in the joint member 10 located outside the outer casing 2, and the balance adjustment can be performed without removing the outer casing 2 or the like. Further, the position corresponding to the balance adjustment position 9 may be adjusted as a fixed position in the adapter 10 by changing the weight of the bolt or the spacer used at the fixed position. In this way, it is not necessary to re-prepare the member for weighting, and the configuration for fixing it is not required, and the number of parts can be reduced to a minimum. Further, in addition to the balance adjustment position 9, the balance adjustment operation of the rotor 5 may be performed at a position where the circumference Φ is ±90° apart as the balance adjustment position. In this way, the balance between the deformation component in the deformation direction P and the deformation component orthogonal to the deformation direction P can be balanced. Further, the balance adjustment position 9 can be changed, and the position on the opposite side of the 180 degree balance adjustment position 9 can be used as the balance adjustment position. In this case, the weight in the balance adjustment position 9 is changed or reduced, and the weight is adjusted or weighted. As described in detail above, the balance® adjustment method of the rotary body 1 of the present embodiment and the rotary body 1 to which the balance adjustment method is applied are tightly fitted by temperature deformation, from the central axis (彳) toward The deformation direction P in the direction perpendicular to the axis of the predetermined position around the shaft is deformed, and in the initial state, the imbalance thus generated is eliminated by the weight adjustment at the initial balance position 13. Further, the balance adjustment position 9 is set at a position around the central axis (彳) corresponding to the initial balance position 13 to adjust the long-term imbalance. Therefore, when a long-term imbalance occurs, the imbalance generated over a long period of time can be eliminated by performing weight adjustment at the balance adjustment position 9. As a result, it is possible to omit the operation of measuring the balance adjustment position and direction by the vibration analyzer or the like, and to adjust the weight only, so that the balance can be easily, correctly, and in a short time. Adjustment. (Second Embodiment) A balance adjustment method of the rotary body 20 according to the second embodiment of the present invention and a rotary body 20 to which the balance adjustment method is applied will be described with reference to Figs. 4A, 4B, and 5D. The balance adjustment method of the rotating body shown in the second embodiment differs from the balance adjustment method of the first embodiment in that, as shown in FIG. 4 and FIG. 4, when the initial balance adjustment is performed, The weight of the weight 21 at the initial balance position 22 (balance adjustment position) is set so as to measure the unbalanced weight of the rotor 5 for a long period of time. The relationship between the deformation direction Ρ and the asymmetrical portion 8, the initial balance position 22, and the balance adjustment position 9 is the same as that of the first embodiment, and thus the description thereof is omitted. The weight 21 is arranged to correct the imbalance generated in the deformation direction when the hot press is introduced, and the black circle indicated by the symbol M2 after the initial balance adjustment in the first embodiment is not only the minimum necessary weight. 〇 〇 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含 包含The position of the white circle is shown, that is, the weight 21 is usually used to correct the imbalance generated on the opposite side of the central axis (彳) by the asymmetrical portion 8 at the time of introduction (the black circle indicated by the symbol M2 in Fig. 5) However, in the present embodiment, after long-term use, as shown in Fig. 5, the white hollow triangle shown by the symbol 23 Α 23C, the pre--16-201017141 deformation at the right angle of the axial direction produces deformation around the shaft. In the direction p, the initial balance adjustment of the rotating body 20 is performed in advance at a change amount larger than the amount of change in the required weight at the initial balance position 22. More specifically, the rotating body 20 is asymmetrically formed by the temperature deformation, and the asymmetric portion 8 is formed around the shaft of the rotor 5, and is asymmetrically held by the central axis (4) of the rotor 5. The deformation direction P on the opposite side of the portion 8 is set in advance so that the rotor 5 is deformed for a long period of time. Then, it is further predicted that the deformation of the rotor 5 which is generated on the opposite side of the non-symmetric portion 8 is long-term enlarged (shown by symbol 23 in FIGS. 4A and 4B, and symbol 2 in FIG. 5). A to 23C show) that the weight of the weight 21 provided in the initial balance position 22 for adjusting the deformation is set to be heavier than necessary. As described in detail above, the balance adjustment method of the rotary body 20 of the second embodiment and the rotary body 20 to which the balance adjustment method is applied are the weights of the weight 21 provided at the initial balance position 22 at the time of initial balance adjustment. It is set to a larger amount of change than the amount of change in weight necessary for forming the most appropriate balance, whereby the balance can be adjusted in the opposite direction to the deformation direction P which is deformed for a long period of time as indicated by the symbols 23 A to 23C. Therefore, it is possible to extend the period in which the maintenance of the rotating body 20 in the deformation direction P is unbalanced and maintenance is necessary, and the rotating body 1 can be used for a long period of time. In the present embodiment, the position from the central axis (彳) and the direction in which the deformation direction P is on the opposite side of the central axis (彳) are set as the initial balance position 22, but the weight 21' is not limited thereto. When the direction from the central axis (彳) and the direction of the deformation P are increased on the opposite side of the central axis (彳), the weight is increased, and the initial balance adjustment is performed, as in the case of the first embodiment -17-201017141. It is also possible to reduce the weight in a direction from the central axis (彳) and a direction in which the deformation direction P substantially coincides with the center axis (彳). In this case, the initial balance adjustment can be performed in a lighter manner than necessary. . Further, the position at which the initial balance adjustment is performed is a position corresponding to the deformation direction P around the axis, and the balance adjustment position for performing the balance adjustment with the long-term change is different in the axial direction or the same position. (Embodiment 3) A balance adjustment method of the rotary body 30 according to the third embodiment of the present invention and a rotary body 30 to which the balance adjustment method is applied will be described with reference to Figs. 6 and 7 . The balance adjustment method of the rotating body shown in the third embodiment differs from the balance adjustment method of the previous embodiment in that it is disposed in the vicinity of the rotor 5 as shown in FIGS. 6 and 7 . The means for detecting the acceleration of the rotor 5, that is, the acceleration detector 31 or the vibration detector 32 for detecting the vibration of the rotor 5, and the calculation means 33 for calculating the weight required for the balance adjustment are based on the calculation means 33. The detection signal output from the acceleration detector 31 or the vibration detector 32 performs balance adjustment at the balance adjustment position 9 corresponding to the deformation direction P. The detection signal of the acceleration detector 31 or the vibration detector 32 is input to the arithmetic means shown by reference numeral 33. Then, in the case where the detecting means is the acceleration detector 31, the calculating means 33 multiplies the acceleration level of the rotor 5 detected by the acceleration detector 31 by the corresponding influence coefficient. Balance adjustment position 9 balance adjustment weight -18- 201017141. Similarly, in the case where the detecting means is the vibration detector 32, the balance of the balance adjusting position 9 is determined by multiplying the vibration level of the rotor 5 detected by the vibration detector 32 by the corresponding influence coefficient. Adjust the weight. Further, the influence coefficient set in the arithmetic means 33 indicates the acceleration level or the vibration level detected by the vibration generated by the situation in which the imbalance occurs, and is necessary for the balance adjustment for the imbalance. The coefficient of the relationship between the weight and the size. Then, the influence coefficient is determined by preliminarily investigating the acceleration level or vibration level and the correlation of the weight necessary to eliminate the imbalance. As described in detail above, the method for adjusting the balance of the rotating body 30 according to the third embodiment and the rotating body 30 to which the balance adjusting method is applied are used to perform acceleration measurement or vibration measurement of the rotating body 30 during balance adjustment. Ii The weight level is determined at the balance adjustment position 9 by the acceleration level or vibration level of the rotating body obtained by the measurement. Then, by measuring the acceleration level or vibration level of the vibration generated by the rotating body 30, the weight required for the balance adjustment can be easily, correctly and in a short time. Make balance adjustments. The embodiments of the present invention have been described in detail above with reference to the drawings. However, the specific configuration is not limited to the embodiment, and design changes and the like that do not depart from the gist of the present invention are also included. In addition, in each of the above-described embodiments, the asymmetrical portions 8' are provided in the rotating bodies 1, 20, and 30, and the position around the axis corresponding to the asymmetrical portion 8 is set as the initial balance position', and the position is adjusted as the pre-balance adjustment position. There is no construction of the asymmetric portion 8. This configuration also performs an initial balance adjustment at a predetermined initial balance position -19 - 201017141 to eliminate the initial imbalance caused by deformation in a predetermined deformation direction P for various reasons, and the position around the corresponding axis is set in advance. The balance is adjusted to adjust the balance of the long-term imbalance easily, correctly, and in a short time. Further, the rotor 5 of the rotating bodies 1, 20, and 30 is provided with a rotating element composed of the armature 6 as an assembled member, and a fixing member 12 made of a magnet is disposed outside the rotating element so as to be coaxial with the rotor 5. However, the present invention is not limited thereto, and a magnet as a rotating element may be provided in the rotor 5, and a motor may be configured to fix the armature on the outer side of the rotating element and on the inner side of the outer casing 2. Further, the method of adjusting the balance between the rotating body 1 and the rotating body 1 of the above-described embodiment is not limited to the rotating body applied to the motor, and can be applied to a rotating body of various rotating machines. According to the balance adjusting method of the rotating body of the present invention, since the position around the shaft corresponding to the direction of the rotating shaft and the direction in which the rotating body is deformed is used as the balance adjusting position, the weight adjustment is performed, so that the adjustment can be easily and accurately performed. The rotating shaft which is thermally deformed and tightly fitted and assembled, and the rotating body formed by the assembled member are unbalanced for a long period of time.旋转 According to the rotating body of the present invention, the position around the shaft corresponding to the direction of the rotating shaft and the direction of the deformation can be used as the balance adjustment position, and the weight can be adjusted. Therefore, the rotation can be easily and accurately adjusted to be tight by thermal deformation.
