ところで、当該等速自在継手を構成するアウタレースは、等速自在継手自体の組立て工程、または、ドライブシャフトの組立て工程においては、複数のアウタレースが互いに密な並列状態で搬送される。このため、当該搬送工程においては、隣り合う同志のアウタレースは、その円筒部の外周の全面が常時接触し得る状態にあって、アウタレースの塗装皮膜が損傷するおそれがあり、また、塗装皮膜が剥がれるおそれがある。従って、本発明の目的は、アウタレースが互いに密な並列状態で搬送される搬送工程において、搬送途中にある隣り合う同志のアウタレースの接触しあう部位を大幅に抑制して、アウタレース同志の接触に起因する塗装皮膜の損傷、塗装皮膜の剥がれを極力防止することにある。   By the way, the outer race constituting the constant velocity universal joint is transported in a closely parallel state with each other in the assembly process of the constant velocity universal joint itself or the assembly process of the drive shaft. For this reason, in the conveyance process, adjacent outer races are in a state in which the entire outer periphery of the cylindrical portion can always be in contact with each other, and there is a risk that the coating film of the outer race may be damaged, and the coating film is peeled off. There is a fear. Accordingly, an object of the present invention is to significantly suppress the contact area between adjacent outer races in the middle of conveyance in the conveyance process in which the outer races are conveyed in a closely parallel state, resulting from contact between the outer races. The purpose is to prevent the paint film from being damaged and peeling of the paint film as much as possible.

本発明は、等速自在継手に関する。本発明に係る等速自在継手は、シャフトの一端に連結されてドライブシャフトを構成する等速自在継手であって、当該等速自在継手を構成するアウタレースは、円筒部の外周における一端側開口部の近傍の部位にブーツまたはブーツアダプターの一端が嵌着される円環状溝部を有するとともに、同円筒部の外周における前記円環状溝部より他端側の部位の全周に塗装皮膜を有し、前記他端側の塗装皮膜を有する部位の最大外径寸法が前記円環状溝部より一端側の部位の最大外径寸法より小径に形成されていることを特徴とするものである。   The present invention relates to a constant velocity universal joint. The constant velocity universal joint according to the present invention is a constant velocity universal joint that is connected to one end of a shaft to constitute a drive shaft, and the outer race that constitutes the constant velocity universal joint has an opening at one end on the outer periphery of the cylindrical portion. Having an annular groove portion into which one end of a boot or a boot adapter is fitted in a portion in the vicinity of, and having a coating film on the entire circumference of the portion on the other end side of the annular groove portion on the outer periphery of the cylindrical portion, The maximum outer diameter dimension of the part having the coating film on the other end side is formed smaller than the maximum outer diameter dimension of the part on the one end side from the annular groove.

本発明は、ボールタイプのクロスグルーブ型等速ジョイントであって、前記ブーツまたはブーツアダプターは、アウタレースとインナレース間のボール溝に介在するボールの同ボール溝からの脱落を防止する脱落防止機能を有する形式の等速自在継手に適用することが好ましい。   The present invention is a ball-type cross-groove constant velocity joint, wherein the boot or boot adapter has a drop-off preventing function for preventing the ball interposed in the ball groove between the outer race and the inner race from dropping from the same ball groove. It is preferable to apply to the constant velocity universal joint of the type which has.

本発明に係る等速自在継手を構成するアウタレースにおいては、前記円筒部の外周における前記円環状溝部より他端側の塗装皮膜を有する部位の最大外径寸法を、前記円環状溝部における底部の外径寸法より大径に形成する構成を採ることができ、また、前記円筒部の外周における前記円環状溝部より他端側の塗装皮膜面の部位の最大外径寸法を、前記円環状溝部における底部の外径寸法と同等の径に形成する構成を採ることができる。   In the outer race constituting the constant velocity universal joint according to the present invention, the maximum outer diameter dimension of the portion having the coating film on the other end side of the annular groove portion on the outer periphery of the cylindrical portion is set to the outside of the bottom portion of the annular groove portion. It is possible to adopt a configuration in which the diameter is formed to be larger than the diameter dimension, and the maximum outer diameter dimension of the portion of the coating film surface on the other end side from the annular groove portion on the outer periphery of the cylindrical portion is set to the bottom portion in the annular groove portion. The structure formed in the diameter equivalent to the outer diameter size of can be taken.

本発明に係る等速自在継手においては、等速自在継手を構成するアウタレースの円筒部の外周における前記円環状溝部より他端側の部位である塗装皮膜を有する部位の最大外径寸法は、前記円環状溝部より一端側の部位の最大外径寸法より小径に形成されている。このため、当該アウタレースにおいては、等速自在継手自体の組立て工程、または、ドライブシャフトの組立て工程における互いに密な並列状態で搬送途中、隣り合う同志のアウタレースが傾斜状態を呈していない場合には、塗装皮膜面が互いに接触することがなく、塗装皮膜の損傷や剥がれ等の発生は防止される。また、当該アウタレースが搬送途中に傾斜状態を呈した場合には、隣り合う同志のアウタレースは塗装皮膜面の１点の部位で接触することになり、塗装皮膜面における接触部位が極小の部位に限定されることになって、塗装皮膜の損傷や剥がれ等の発生が大幅に抑制されることになる。   In the constant velocity universal joint according to the present invention, the maximum outer diameter dimension of the portion having the coating film which is the portion on the other end side of the annular groove portion on the outer periphery of the cylindrical portion of the outer race constituting the constant velocity universal joint is It is formed to have a smaller diameter than the maximum outer diameter dimension at one end side from the annular groove. For this reason, in the outer race, when the adjacent outer races do not exhibit an inclined state during conveyance in a close parallel state in the assembly process of the constant velocity universal joint itself or the drive shaft assembly process, The coating film surfaces do not come into contact with each other, and the coating film is prevented from being damaged or peeled off. In addition, when the outer race is inclined in the middle of conveyance, adjacent outer races come into contact with each other at one point on the paint film surface, and the contact part on the paint film surface is limited to a minimum part. As a result, the occurrence of damage or peeling of the coating film is greatly suppressed.

本発明に係る等速自在継手においては、アウタレースの円筒部の外周における前記円環状溝部より他端側の塗装皮膜を有する部位の最大外径寸法を、前記円環状溝部における底部の外径寸法より大径に形成する形態を採ることができる。当該形態を採ることにより、アウタレースが本来有する剛性を確保することができ、かつ、等速自在継手の剛性を確保することができる。   In the constant velocity universal joint according to the present invention, the maximum outer diameter of the portion having the coating film on the other end side from the annular groove on the outer periphery of the cylindrical portion of the outer race is determined from the outer diameter of the bottom of the annular groove. It is possible to adopt a form that forms a large diameter. By adopting this form, the rigidity inherent in the outer race can be secured, and the rigidity of the constant velocity universal joint can be secured.

また、本発明に係る等速自在継手においては、アウタレースの円筒部の外周における前記円環状溝部より他端側の塗装皮膜を有する部位の最大外径寸法を、前記円環状溝部における底部の外径寸法と同等の径に形成する形態を採ることができる。当該形態を採ることにより、前記円環状溝部の加工と円筒部における他端側の部位の加工とを一体で行うことができ、前記円環状溝部の単独の加工を省略し得て、加工工数の削減およびコストの低減を図ることができる。   In the constant velocity universal joint according to the present invention, the maximum outer diameter of the portion having the coating film on the other end side from the annular groove on the outer periphery of the cylindrical portion of the outer race is defined as the outer diameter of the bottom of the annular groove. The form formed in the diameter equivalent to a dimension can be taken. By adopting this form, the processing of the annular groove portion and the processing of the other end side portion of the cylindrical portion can be performed integrally, the single processing of the annular groove portion can be omitted, and the number of processing steps can be reduced. Reduction and cost reduction can be achieved.

本発明は、シャフトの一端に連結されてドライブシャフトを構成する等速自在継手に関する。図１には、本発明が適用対象とする等速自在継手を示している。等速自在継手は、ボールタイプのクロスグルーブ型ジョイント１０ａである。当該ジョイント１０ａは、シャフト１０ｂの一端に連結されて、シャフト１０ｂおよびその他端に連結される図示しないトリポート型スライド式ジョイントとともにドライブシャフトＤＳを構成する。   The present invention relates to a constant velocity universal joint that is connected to one end of a shaft to constitute a drive shaft. FIG. 1 shows a constant velocity universal joint to which the present invention is applied. The constant velocity universal joint is a ball-type cross-groove joint 10a. The joint 10a is connected to one end of the shaft 10b, and constitutes a drive shaft DS together with a triport type sliding joint (not shown) connected to the shaft 10b and the other end.

当該ジョイント１０ａは、アウタレース１１、シャフト１０ｂの先端部に組付けたインナレース１２、複数のボール１３、および、各ボール１３を保持するケージ１４を備えるもので、各ボール１３は、ケージ１４に保持された状態で、アウタレース１１の内周面およびインナレース１２の外周面に設けられている各ボール溝１１ａ，１２ａに転動可能に嵌合して、当該ジョイント１０ａを構成している。   The joint 10 a includes an outer race 11, an inner race 12 assembled at the tip of the shaft 10 b, a plurality of balls 13, and a cage 14 that holds each ball 13. Each ball 13 is held by the cage 14. In this state, the joint 10a is configured by rollingly fitting in each of the ball grooves 11a and 12a provided on the inner peripheral surface of the outer race 11 and the outer peripheral surface of the inner race 12.

当該ドライブシャフトＤＳにおいては、当該ジョイント１０ａを構成するアウタレース１１の円筒部１１ａの一端側開口部の近傍の部位にブーツ１０ｃの先端部がブーツアダプター１５を介して組付けられている。当該ブーツ１０ｃにおいては、その後端部がシャフト１０ｂの先端側の部位に組付けられていて、アウタレース１０ａの一端開口部を液密的に覆蓋している。当該ブーツ１０ｃは、アウタレース１０ａとシャフト１０ｂ間に組付けられた状態では、ブーツアダプター１５が各ボール１３の各ボール溝１１ａ、１２ａからの脱落を防止すべく機能する。   In the drive shaft DS, the distal end portion of the boot 10c is assembled via a boot adapter 15 at a portion near the opening on the one end side of the cylindrical portion 11a of the outer race 11 constituting the joint 10a. In the boot 10c, the rear end portion is assembled to the front end side portion of the shaft 10b, and the one end opening portion of the outer race 10a is liquid-tightly covered. When the boot 10c is assembled between the outer race 10a and the shaft 10b, the boot adapter 15 functions to prevent the balls 13 from dropping from the ball grooves 11a and 12a.

しかして、当該ジョイント１０ａを構成するアウタレース１１の筒体を構成する円筒部１１ｂは、軸方向における外径寸法が同一の円筒状に形成されていて、円筒部１１ｂの外周には、図２に示すように、その円筒部１１ｂの外周における一端開口部の近傍の部位に、ブーツアダプター１５の先端を嵌着するための円環状溝部１１ｃが形成されている。また、アウタレース１１の筒体の外周における円環状溝部１１ｃより他端側の部位の外周全面は塗装されていて、円筒部１１ｂの外周における他端側の部位１１ｂ1は塗装皮膜を有する部位となっている。かかる構成のアウタレース１１の円筒部１１ｂにおいては、従来は円環状溝部１１ｃよりも一端開口部側の部位１１ｂ2の外径寸法（ФＤ）と、他端側の部位である塗装皮膜を有する部位１１ｂ1の外径寸法（ФＤ）は、図２に示すように同一であった。   Thus, the cylindrical portion 11b constituting the cylindrical body of the outer race 11 constituting the joint 10a is formed in a cylindrical shape having the same outer diameter in the axial direction, and the outer periphery of the cylindrical portion 11b is shown in FIG. As shown, an annular groove portion 11c for fitting the tip of the boot adapter 15 is formed in the vicinity of the one end opening on the outer periphery of the cylindrical portion 11b. Further, the entire outer periphery of the portion on the other end side from the annular groove portion 11c on the outer periphery of the cylindrical body of the outer race 11 is painted, and the portion 11b1 on the other end side on the outer periphery of the cylindrical portion 11b is a portion having a coating film. Yes. In the cylindrical portion 11b of the outer race 11 having such a configuration, conventionally, the outer diameter dimension (ФD) of the portion 11b2 on the one end opening side of the annular groove portion 11c and the portion 11b1 having the coating film on the other end side are provided. The outer diameter dimension (ФD) was the same as shown in FIG.

アウタレース１１は、当該ジョイント１０ａ自体の組立て工程、または、ドライブシャフトの組立て工程においては、図３に模式的に示すように、複数のアウタレース１１が互いに密な並列状態で搬送される。この場合、アウタレース１１の円筒部１１ｂにおける一端側の部位１１ｂ2の外径寸法（ФＤ）と、他端側の部位である塗装皮膜を有する部位１１ｂ1の外径寸法とが同一であるため、隣り合う同志のアウタレース１１は、その円筒部１１ｂの外周の全面が常時接触し得る状態にある。このため、アウタレース１１の塗装皮膜を有する部位１１ｂ1の塗装皮膜面が損傷するおそれがあり、また、塗装皮膜が剥がれるおそれがあった。   In the assembly process of the joint 10a itself or the assembly process of the drive shaft, the outer race 11 is conveyed in a close parallel state with each other as schematically shown in FIG. In this case, since the outer diameter dimension (ФD) of the part 11b2 on one end side in the cylindrical portion 11b of the outer race 11 is the same as the outer diameter dimension of the part 11b1 having the coating film on the other end side, they are adjacent to each other. The comrades outer race 11 is in a state where the entire outer surface of the cylindrical portion 11b can always contact. For this reason, the coating film surface of the portion 11b1 having the coating film of the outer race 11 may be damaged, and the coating film may be peeled off.

本発明の目的は、アウタレースが互いに密な並列状態で搬送される途中での隣り合う同志のアウタレースの接触を大幅に抑制して、アウタレース同志の接触に起因する塗装皮膜面の損傷、塗装皮膜の剥がれを極力防止することにあり、本発明では、等速自在継手を構成するアウタレース１１Ａを、図４に示す構成としている。   The object of the present invention is to greatly suppress the contact between adjacent outer races while the outer race is being transported in close parallel with each other, and to prevent damage to the paint film surface caused by the contact between the outer races. In order to prevent peeling as much as possible, the outer race 11A constituting the constant velocity universal joint is configured as shown in FIG.

当該アウタレース１１Ａは、円筒部１１ｂの外周における一端開口部の近傍の部位に、ブーツアダプター１５の先端が嵌着される円環状溝部１１ｃが形成されている点、および、円筒部１１ａの外周における円環状溝部１１ｂより他端側の部位は塗装されていて、円筒部１１ｂの外周における他端側の部位１１ｂ1の外周面が塗装皮膜を有する部位に形成されている点では、アウタレース１１とは共通する。しかしながら、当該アウタレース１１Ａは、円環状溝部１１ｃを基準とした一端側の部位１１ｂ2の外径寸法と、他端側の部位である塗装皮膜を有する部位１１ｂ1の外径寸法との関係においては、アウタレース１１とは相違する。すなわち、当該アウタレース１１Ａにおいては、図４に示すように、一端側の部位１１ｂ2の外径寸法（ФＤ1）に対して、塗装皮膜を有する他端側の部位１１ｂ1の外径寸法（ФＤ2）が小さく設定されている。本実施形態では、他端側の部位１１ｂ1の外径（ФＤ2）は、（ФＤ1−０．５ｍｍ）の寸法に設定されている。   In the outer race 11A, an annular groove portion 11c into which the tip of the boot adapter 15 is fitted is formed at a portion near the one end opening portion on the outer periphery of the cylindrical portion 11b, and a circle on the outer periphery of the cylindrical portion 11a. The outer race 11 is common in that the portion on the other end side from the annular groove portion 11b is painted, and the outer peripheral surface of the other end portion portion 11b1 on the outer periphery of the cylindrical portion 11b is formed at a portion having a coating film. . However, the outer race 11A has an outer race in the relationship between the outer diameter of the portion 11b2 on one end side with respect to the annular groove portion 11c and the outer diameter of the portion 11b1 having the coating film on the other end side. 11 is different. That is, in the outer race 11A, as shown in FIG. 4, the outer diameter (ФD2) of the portion 11b1 on the other end side having the coating film is smaller than the outer diameter (ФD1) of the portion 11b2 on the one end side. Is set. In the present embodiment, the outer diameter (ФD2) of the portion 11b1 on the other end side is set to a size of (ФD1−0.5 mm).

当該設定は、円筒部１１ｂにおける塗装皮膜を有する他端側の部位１１ｂ1の最大外径寸法が、一端側の部位１１ｂ2の最大外径寸法より小径に形成するという技術的思想に基づくものである。但し、当該実施形態では、塗装皮膜を有する部位１１ｂ1の外径寸法（ФＤ2）である（ФＤ1−０．５ｍｍ）は、円環状溝部１１ｃにおける底部の外径寸法よりは大径に形成されている。当該設定によれば、アウタレース１１Ａが本来有する剛性を確保することができ、かつ、等速自在継手の剛性を確保することができる。当該アウタレース１１Ａにおいては、塗装皮膜を有する部位１１ｂ1の外径寸法（ФＤ2）を、円環状溝部１１ｃにおける底部の外径寸法と同等の径に形成する形態を採ることもできる。当該実施形態を採れば、円環状溝部１１ｃの加工と円筒部における他端側の部位の加工とを一体で行うことができ、円環状溝部１１ｃの単独の加工を省略し得て、加工工数の削減およびコストの低減を図ることができるという利点がある。   This setting is based on the technical idea that the maximum outer diameter of the portion 11b1 on the other end side having the coating film in the cylindrical portion 11b is smaller than the maximum outer diameter of the portion 11b2 on the one end side. However, in this embodiment, the outer diameter dimension (ФD2) (ФD1−0.5 mm) of the portion 11b1 having the coating film is formed larger than the outer diameter size of the bottom portion in the annular groove portion 11c. . According to the setting, the rigidity inherent in the outer race 11A can be secured, and the rigidity of the constant velocity universal joint can be secured. In the outer race 11A, the outer diameter dimension (ФD2) of the portion 11b1 having the coating film may be formed to have a diameter equivalent to the outer diameter dimension of the bottom portion in the annular groove portion 11c. If the said embodiment is taken, the process of the annular groove part 11c and the process of the site | part of the other end side in a cylindrical part can be performed integrally, the single process of the annular groove part 11c can be abbreviate | omitted, and processing man-hours can be reduced. There is an advantage that reduction and cost reduction can be achieved.

当該アウタレース１１Ａは、当該ジョイント１０ａ自体の組立て工程、または、ドライブシャフトの組立て工程においては、図５に模式的に示すように、複数のアウタレース１１Ａが互いに密な並列状態で搬送される。当該搬送状態は、アウタレース１１の搬送状態と同様であるが、この場合には、アウタレース１１Ａの円筒部１１ｂにおける一端側の部位１１ｂ2の外径寸法（ФＤ1）に比較して、塗装皮膜を有する他端側の部位１１ｂ1の外径寸法（ФＤ1−０．５ｍｍ）が小径であるため、互いに密な並列状態で搬送途中、隣り合う同志のアウタレース１１Ａが傾斜状態を呈していない場合には、塗装皮膜面が互いに接触することがなく、塗装皮膜面の損傷や塗装皮膜の剥がれ等の発生は防止される。また、アウタレース１１Ａが搬送途中に傾斜状態を呈した場合には、隣り合う同志のアウタレース１１Ａは塗装皮膜面の１点の部位で接触することになって、塗装皮膜面での接触部位が極小の部位に限定されることになって、塗装皮膜面の損傷を最小限に止めることができるとともに、塗装皮膜の剥がれの発生が大幅に抑制することができる。   In the assembly process of the joint 10a itself or the assembly process of the drive shaft, the outer race 11A is conveyed in a close parallel state with each other as schematically shown in FIG. The conveyance state is the same as the conveyance state of the outer race 11, but in this case, the outer race 11A has a coating film as compared with the outer diameter dimension (ФD1) of the portion 11b2 on one end side of the cylindrical portion 11b. Since the outer diameter dimension (ФD1-0.5 mm) of the end portion 11b1 is small, a coating film is formed when adjacent outer races 11A do not exhibit an inclined state during conveyance in a closely parallel state. The surfaces do not come into contact with each other, and damage to the coating film surface and peeling of the coating film are prevented. Further, when the outer race 11A is inclined during the conveyance, the adjacent outer races 11A come into contact with each other at one point on the paint film surface, and the contact part on the paint film surface is minimal. As a result, the damage to the coating film surface can be minimized, and the occurrence of peeling of the coating film can be greatly suppressed.
