Description
本發明是有關於一種自行車的零件，特別是指一種用於傳動鏈條的耐磨抗沾齒盤。 The present invention relates to a bicycle part, and more particularly to a wear resistant anti-scratch toothed disc for a drive chain.
現今許多人都會採取自行車搭配大眾交通運輸工具的環保旅遊方式。此種旅遊方式，常常需要將自行車搬上大眾交通運輸工具，或自大眾交通運輸工具上搬下來，因此重量較輕的自行車往往能較受使用者歡迎與青睞。減輕自行車重量的手段雖然有很多，但最常見的莫過於使用鋁合金等輕質材料，然而鋁合金雖然質地輕盈，但硬度卻不高而不甚耐磨，並具有易沾附雜質的缺點。舉例來說，如圖1所示的一個齒盤9，由於需與鏈條組配並經常與鏈條摩擦，故容易磨損，且該齒盤9磨損之後所形成的凹凸不平結構，將會使該齒盤9更容易沾黏雜質，並因雜質的存在而加劇該齒盤9受摩擦的情況，形成惡性循環，有待改善。 Many people today take the environmentally friendly way of traveling with bicycles and mass transit. This type of travel often requires the bicycle to be moved to mass transit or removed from mass transit, so lighter weight bicycles are often more popular and popular with users. Although there are many ways to reduce the weight of bicycles, the most common one is to use lightweight materials such as aluminum alloy. However, although the aluminum alloy is light in weight, the hardness is not high and it is not wearable, and has the disadvantage of being easily contaminated. For example, a toothed disc 9 as shown in FIG. 1 is easy to wear due to the need to be combined with the chain and often rubbed against the chain, and the uneven structure formed after the toothed disc 9 is worn will make the tooth The disk 9 is more likely to be contaminated with impurities, and the toothed disc 9 is abraded by the presence of impurities, forming a vicious circle, which needs to be improved.
本發明的目的，在於提供一種能夠克服先前技術的至少一個缺點的耐磨抗沾齒盤。 It is an object of the present invention to provide a wear resistant sprocket wheel that overcomes at least one of the disadvantages of the prior art.
該耐磨抗沾齒盤包含一個齒盤單元、一個耐磨層，以 及一層抗沾層。該耐磨層設置在該齒盤單元上，並包括一個相反於該齒盤單元的耐磨粗糙面。該耐磨粗糙面形成有數個突起的耐磨突出部。該抗沾層與該齒盤單元相間隔，並包括一個貼合該耐磨粗糙面的抗沾粗糙面。該抗沾粗糙面形成有數個與該等耐磨突出部卡合的抗沾突出部。 The wear resistant anti-scratch plate comprises a toothed disc unit and a wear layer, And a layer of anti-staining layer. The wear layer is disposed on the chainring unit and includes a wear resistant rough surface opposite the toothed disc unit. The wear resistant rough surface is formed with a plurality of raised wear protrusions. The anti-staining layer is spaced from the sprocket unit and includes a smear resistant surface that conforms to the wear resistant rough surface. The anti-staining rough surface is formed with a plurality of anti-stick projections that engage with the wear-resistant projections.
該耐磨抗沾齒盤的功效在於：該耐磨層與該抗沾層，分別具有耐摩擦及防雜質沾黏的特性，故本發明耐磨抗沾齒盤能在一開始具有抗沾黏特性，並在使用一段時間至該等耐磨突出部露出後，同時兼具耐磨及抗沾之雙重特點，並解決以往習知的齒盤易沾黏雜質且易磨損的缺點。 The wear-resistant anti-stick tooth plate has the advantages that the wear-resistant layer and the anti-staining layer have the characteristics of resistance to friction and anti-contamination, respectively, so that the wear-resistant anti-stick tooth plate of the invention can have anti-adhesion at the beginning. The characteristics, and after a period of use until the wear-resistant protrusions are exposed, at the same time have the dual characteristics of wear resistance and anti-sticking, and solve the defects that the conventional toothed disc is easy to stick to impurities and is easy to wear.

在實施方式被詳細描述前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。 Before the embodiments are described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖2及圖3，本發明耐磨抗沾齒盤的一個第一實施例，包含一個齒盤單元1、一層熔射噴塗地設置在該齒盤單元1上的耐磨層2，以及一層熔射噴塗地設置在該耐磨層2上並與該齒盤單元1相間隔的抗沾層3。 Referring to Figures 2 and 3, a first embodiment of the wear-resistant anti-scratch disk of the present invention comprises a toothed disc unit 1, a wear-resistant layer 2 spray-sprayed on the chain-ring unit 1, and a layer An anti-staining layer 3 disposed on the wear layer 2 and spaced apart from the sprocket unit 1 by spray coating.
該齒盤單元1的材料為鋁合金，並具有一個透過噴砂處理而形成的齒盤粗糙面11。所述的鋁合金能為7系列(7XXX)或者6系列(6XXXX)之鋁合金，但在本發明的其他實施態樣中，該齒盤單元1的材料也能為鋼材。由於該齒盤單元1的外形非本發明的重點，且能依設計需求作變化，故無需特別限制。 The toothed disc unit 1 is made of an aluminum alloy and has a spur rough surface 11 formed by sand blasting. The aluminum alloy can be an aluminum alloy of 7 series (7XXX) or 6 series (6XXXX), but in other embodiments of the invention, the material of the chainring unit 1 can also be steel. Since the shape of the chainring unit 1 is not the focus of the present invention and can be changed according to design requirements, it is not particularly limited.
該耐磨層2的材料為鎳鋁合金，並具有一個與該齒盤單元1的該齒盤粗糙面11貼合的貼合粗糙面211，以及一個相反於該貼合粗糙面211的耐磨粗糙面221。該耐磨層2與該齒盤單元1彼此以粗糙面卡合的設計，有利於提高兩者間的結合性。該耐磨粗糙面221形成有數個往該抗沾層3突起的耐磨突出部222。在本發明的其他實施態樣中，該耐磨層2的材料也能為不鏽鋼、鈦合金或他種鎳合金。所述的鈦合金舉例來說能為含有6wt%鋁、4wt%釩及餘量鈦的鈦合金，或者為含有6wt%鋁、6wt%釩、2wt%錫及餘量鈦的鈦合金。所述的他種鎳合金，舉例來說可為Inconel 718合金。 The wear layer 2 is made of a nickel-aluminum alloy and has a conforming rough surface 211 that fits the sprocket rough surface 11 of the sprocket unit 1, and a wear resistant surface opposite to the conforming rough surface 211. Rough surface 221. The design of the wear layer 2 and the toothed disc unit 1 being roughened to each other is advantageous for improving the bonding between the two. The wear-resistant rough surface 221 is formed with a plurality of wear-resistant projections 222 protruding toward the anti-stick layer 3. In other embodiments of the invention, the material of the wear layer 2 can also be stainless steel, titanium alloy or other nickel alloy. The titanium alloy can be, for example, a titanium alloy containing 6 wt% aluminum, 4 wt% vanadium, and the balance titanium, or a titanium alloy containing 6 wt% aluminum, 6 wt% vanadium, 2 wt% tin, and the balance titanium. The other nickel alloy described may be, for example, Inconel 718 alloy.
該抗沾層3的材料為聚四氟乙烯，並包括一個貼合該耐磨粗糙面221的抗沾粗糙面31，以及一個相反於該抗沾粗糙面31的抗沾表面32。該抗沾粗糙面31形成有數個往該耐磨層2突出且與該等耐磨突出部222卡合的抗沾突出部311。該抗沾層3與該耐磨層2彼此以粗糙面卡合的設計，也有利於提高兩者間的結合性。在本發明的其他實施態樣中，該抗沾層3也能為類鑽材料。當該抗沾層3的材料為聚四氟乙烯時，是以塗佈烘烤的方式將聚四氟乙烯設置於該耐磨層2上，而當該抗沾層的材料為類鑽材料時，則是以物理氣相沉積的方式，使類鑽材料形成於該耐磨層2上。 The material of the anti-staining layer 3 is polytetrafluoroethylene, and includes a stain-resistant rough surface 31 to which the wear-resistant rough surface 221 is attached, and a stain-resistant surface 32 opposite to the anti-stick rough surface 31. The anti-staining rough surface 31 is formed with a plurality of anti-stick protrusions 311 protruding toward the wear-resistant layer 2 and engaged with the wear-resistant protrusions 222. The design of the anti-staining layer 3 and the wear-resistant layer 2 being roughened to each other is also advantageous for improving the bonding between the two. In other embodiments of the invention, the anti-staining layer 3 can also be a diamond-like material. When the material of the anti-staining layer 3 is polytetrafluoroethylene, the polytetrafluoroethylene is disposed on the wear-resistant layer 2 by coating baking, and when the material of the anti-staining layer is a diamond-like material. The diamond-like material is formed on the wear-resistant layer 2 by means of physical vapor deposition.
本第一實施例於剛開始使用時，由於該抗沾層3的材料本身特性，該抗沾表面32的表面能相當小，不利於泥沙及粉塵等雜質沾黏，而具有抗沾黏並利於順暢運轉的效果，而當本第一實施使用一段時間後，該抗沾層3將因摩擦而變薄，並使本第一實施例呈現如圖3所示的狀態。從圖3中可以看到，該耐磨層2的該等耐磨突出部222部分地突出新形成的抗沾表面32，而能保護位於該等耐磨突出部222間的該等抗沾突出部311，避免該等抗沾突出部311因摩擦而消失，且由於新形成的該抗沾表面32具有抗沾效果，該等耐磨突出部222具有耐磨效果，故本第一實施例能同時兼具耐磨及抗沾雙重特性。要注意的是，於生產或販售時，也可先針對該抗沾層3進行打磨，直接使本第一實施例呈現如圖3所示的狀態，而直接具 有耐磨及抗沾雙重特性。 When the first embodiment is used at the beginning, due to the material properties of the anti-staining layer 3, the surface energy of the anti-staining surface 32 is relatively small, which is not conducive to the adhesion of impurities such as sand and dust, and has anti-adhesion and The effect of smooth operation is facilitated, and when the first embodiment is used for a period of time, the anti-staining layer 3 will be thinned by friction, and the first embodiment assumes a state as shown in FIG. As can be seen in Figure 3, the wear resistant projections 222 of the wear layer 2 partially protrude the newly formed offset surface 32 to protect the resistant projections between the wear resistant projections 222. The portion 311 prevents the anti-stick protrusions 311 from disappearing due to friction, and since the newly formed anti-stick surface 32 has an anti-sticking effect, the wear-resistant protrusions 222 have a wear-resisting effect, so the first embodiment can At the same time, it has both wear resistance and anti-stick properties. It should be noted that, in the production or the sale, the anti-staining layer 3 can also be polished first, so that the first embodiment is directly in the state shown in FIG. It has the dual characteristics of wear resistance and anti-sticking.
參閱圖4，本發明耐磨抗沾齒盤的一個第二實施例與該第一實施例類似，不同的地方在於該齒盤單元1包括一層材料為鋁合金且與該耐磨層2相間隔的第一金屬層12，以及一層材料為鎳鋁合金並供該耐磨層2設置的第二金屬層13。該耐磨層2的材料為陶瓷材料。所述的陶瓷材料，於本第二實施例中為氮化鈦(TiN)，但在本發明的其他實施態樣中，該陶瓷材料也能為三氧化二鋁(Al2O3)、三氧化二鉻(Cr2O3)或碳化矽(SiC)。 Referring to Figure 4, a second embodiment of the wear resistant toothed disc of the present invention is similar to the first embodiment except that the chainring unit 1 comprises a layer of aluminum alloy and is spaced from the wear layer 2. The first metal layer 12, and a layer of material is a nickel-aluminum alloy and a second metal layer 13 provided for the wear layer 2. The material of the wear layer 2 is a ceramic material. The ceramic material is titanium nitride (TiN) in the second embodiment, but in other embodiments of the invention, the ceramic material can also be aluminum oxide (Al 2 O 3 ), three Chromium oxide (Cr 2 O 3 ) or lanthanum carbide (SiC).
由於本第二實施例同樣設置有該耐磨層2及該抗沾層3，因此本第二實施例同樣也能達成與該第一實施例相同的耐磨抗沾效果。本第二實施例的特別之處在於該第二金屬層13的膨脹係數界於鋁合金及陶瓷材料間，能降低鋁合金與陶瓷材料膨脹係數差異所帶來的影響。 Since the wear-resistant layer 2 and the anti-staining layer 3 are also provided in the second embodiment, the second embodiment can also achieve the same wear-resistance and anti-staining effect as the first embodiment. The second embodiment is special in that the expansion coefficient of the second metal layer 13 is between the aluminum alloy and the ceramic material, which can reduce the influence of the difference in expansion coefficient between the aluminum alloy and the ceramic material.
綜上所述，本發明耐磨抗沾齒盤的功效在於：設置在該齒盤單元1上的該耐磨層2與該抗沾層3，分別具有耐磨擦及能防止雜質沾黏的特性，故本發明耐磨抗沾齒盤能在一開始具有抗沾黏特性，並在使用一段時間至該等耐磨突出部222露出後，同時兼具耐摩擦及抗沾黏之雙重特點，並解決以往的齒盤易沾黏雜質且易磨損的問題。 In summary, the anti-scratch and anti-scratch disk of the present invention has the effect that the wear-resistant layer 2 disposed on the toothed disc unit 1 and the anti-staining layer 3 respectively have abrasion resistance and can prevent impurities from sticking. The anti-sticking disc of the present invention can have anti-adhesive properties at the beginning, and after being used for a period of time until the wear-resistant protruding portions 222 are exposed, both of them have the dual characteristics of friction resistance and anti-adhesion. And solve the problem that the prior toothed disc is easy to stick to impurities and is easy to wear.
惟以上所述者，僅為本發明的實施例而已，當不能以 此限定本發明實施的範圍，凡是依本發明申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本發明專利涵蓋的範圍內。在以下的說明內容中，類似或相同的元件將以相同的編號來表示。 However, the above is only an embodiment of the present invention, when The scope of the present invention is defined by the scope of the present invention, and the equivalent equivalents and modifications of the present invention are still within the scope of the present invention.
