Description
本発明は、自動車や各種産業機械において使用される固定式等速自在継手に関する。 The present invention relates to a fixed type constant velocity universal joint used in automobiles and various industrial machines.
自動車及びこれに準ずる各種車両においては、エンジンからの駆動力をホイールに伝達する動力伝達経路に、二軸間で角度変位や軸方向変位があった場合でも等速で回転動力を伝達することが可能な等速自在継手を配設することが行われている。等速自在継手には、プランジング運動（軸方向変位）を行わない固定式等速自在継手とプランジング運動を行う摺動式等速自在継手がある。 In automobiles and similar vehicles, rotational power can be transmitted at a constant speed even when there is angular displacement or axial displacement between the two axes in the power transmission path that transmits the driving force from the engine to the wheels. Possible constant velocity universal joints are arranged. The constant velocity universal joint includes a fixed constant velocity universal joint that does not perform plunging motion (axial displacement) and a sliding constant velocity universal joint that performs plunging motion.
図１は本発明の固定式等速自在継手を示すものであるが、固定式等速自在継手の基本的な構成を説明するのに便宜的に援用すると、固定式等速自在継手は、図１（Ａ）（Ｂ）に示すように、外輪１と、内輪２と、複数のボール３と、保持器４を主要な構成要素とする。 FIG. 1 shows a fixed type constant velocity universal joint according to the present invention. When used for convenience in explaining the basic configuration of the fixed type constant velocity universal joint, As shown to 1 (A) (B), the outer ring | wheel 1, the inner ring | wheel 2, the some ball | bowl 3, and the holder | retainer 4 are used as a main component.
外輪１の凹球面状内周面１ａ（以下、内球面という。）に形成した複数の案内溝１ｂと、内輪２の凸球面状外球面２ａ（以下、外球面という。）に形成した複数の案内溝２ｂとの間に、それぞれ１個ずつボール３を配設している。そして、各ボール３を収容する複数のポケット４ａを形成した保持器４を、外輪１の内球面１ａと内輪２の外球面２ａとの間に配設している。 A plurality of guide grooves 1b formed on a concave spherical inner peripheral surface 1a (hereinafter referred to as an inner spherical surface) of the outer ring 1, and a plurality of guide grooves 1b formed on a convex spherical outer spherical surface 2a (hereinafter referred to as an outer spherical surface) of the inner ring 2. One ball 3 is provided between each guide groove 2b. A cage 4 having a plurality of pockets 4 a for accommodating the balls 3 is disposed between the inner spherical surface 1 a of the outer ring 1 and the outer spherical surface 2 a of the inner ring 2.
内輪を保持器内に組み付けるには、図１０に示すように、内輪２の案内溝２ｂを保持器４の入口部４ｄに跨がせる。跨がせた案内溝２ｂを中心に矢印Ａ方向に回転させて、内輪２の案内溝２ｂ相互間の凸部２ｃを保持器４のポケット４ａに挿入すると共に、内輪２を保持器４内へ入れる。そして、内輪２を保持器４内で９０°回転させて球面係合させ組み付けている。 In order to assemble the inner ring into the cage, the guide groove 2b of the inner ring 2 is straddled over the inlet 4d of the cage 4 as shown in FIG. The projecting portion 2c between the guide grooves 2b of the inner ring 2 is inserted into the pocket 4a of the retainer 4 while rotating the guide ring 2b around the guide groove 2b, and the inner ring 2 is moved into the retainer 4. Put in. And the inner ring | wheel 2 is rotated 90 degrees within the holder | retainer 4, is spherically engaged, and is assembled | attached.
ところで、外輪の軸線と内輪の軸線とがなす作動角の最大値を大きくとれるようにするために、内輪の軸線方向寸法を大きくして、内輪の案内溝を長く形成する場合がある。内輪の軸線方向寸法を大きくするに伴って、凸部の軸線方向寸法が保持器のポケットより大きくなると、組み付け時に凸部をポケット内に挿入することができなくなる。 By the way, in order to make it possible to increase the maximum value of the operating angle formed by the axis of the outer ring and the axis of the inner ring, the dimension of the inner ring in the axial direction may be increased and the guide groove of the inner ring may be formed longer. If the axial dimension of the convex portion becomes larger than the pocket of the cage as the axial dimension of the inner ring is increased, the convex portion cannot be inserted into the pocket during assembly.
この問題を解決するために、図１１に示すように、内輪２の外球面２ａの一端を切り欠いて、傾斜面２ｅ又は段差面を形成したものがある（例えば、特許文献１又は特許文献２参照）。この傾斜面２ｅを設けたことにより、凸部２ｃはポケット４ａに隣接する柱部１０との干渉を回避してポケット４ａ内に挿入できる。
しかし、上記特許文献１又は特許文献２の継手は、図１２に示すように、内輪２の回転軸が外輪１の回転軸に対し大きく傾斜した状態（継手が大きな作動角をとった状態）となると、傾斜部２ｅを形成した内輪２の外球面２ａと、保持器４の内球面４ｃとの接触面積は小さくなる。この状態で高トルクを負荷すると、外球面２ａの傾斜部２ｅ（エッジ）が保持器４の内球面４ｃに強く食い込んで保持器４に過大な負荷がかかる虞があった。 However, in the joint of Patent Document 1 or Patent Document 2, as shown in FIG. 12, the rotation shaft of the inner ring 2 is greatly inclined with respect to the rotation shaft of the outer ring 1 (the joint has a large operating angle). Then, the contact area between the outer spherical surface 2a of the inner ring 2 formed with the inclined portion 2e and the inner spherical surface 4c of the cage 4 becomes small. When a high torque is applied in this state, the inclined portion 2e (edge) of the outer spherical surface 2a strongly bites into the inner spherical surface 4c of the cage 4, and there is a possibility that an excessive load is applied to the cage 4.
そこで、本発明は斯かる実情に鑑み、内輪の保持器への食い込み現象を防止して、保持器への負荷を軽減することができる固定式等速自在継手を提供しようとするものである。 Therefore, in view of such circumstances, the present invention intends to provide a fixed type constant velocity universal joint that can prevent the inner ring from biting into the cage and reduce the load on the cage.
請求項１の発明は、内球面に軸方向に延びた複数の案内溝を周方向等間隔に形成した外側継手部材と、外球面に軸方向に延びた複数の案内溝を周方向等間隔に形成した内側継手部材と、前記両継手部材の各案内溝間に配置した複数のトルク伝達ボールと、前記外側継手部材の内球面と前記内側継手部材の外球面との間に介在すると共に前記トルク伝達ボールを収容する複数のポケットを周方向に貫設した保持器を備えた固定式等速自在継手において、前記内側継手部材の案内溝相互間にある複数の外球面のうち、少なくとも１つの外球面の軸線方向の中間部と一端縁の間に、凹部を設けたものである。 According to the first aspect of the present invention, an outer joint member in which a plurality of guide grooves extending in the axial direction on the inner spherical surface are formed at equal intervals in the circumferential direction, and a plurality of guide grooves extending in the axial direction on the outer spherical surface at equal intervals in the circumferential direction. The inner joint member formed, a plurality of torque transmission balls disposed between the guide grooves of the two joint members, the inner spherical surface of the outer joint member and the outer spherical surface of the inner joint member, and the torque A fixed type constant velocity universal joint including a cage in which a plurality of pockets for accommodating a transmission ball are provided in a circumferential direction. At least one outer spherical surface among a plurality of outer spherical surfaces between guide grooves of the inner joint member. A concave portion is provided between the intermediate portion in the axial direction of the spherical surface and one end edge.
内側継手部材を保持器に組み込む際、内側継手部材の外球面に形成した凹部を、保持器の柱部に接触ないし接近させることで、内側継手部材の凸部を保持器のポケットに挿入することができる（図８参照）。この凹部を設けたことにより、内側継手部材の凸部の軸線方向寸法がポケットの周方向幅寸法より大きい場合であっても、内側継手部材の凸部を柱部との干渉を回避してポケット内に挿入できる。 When the inner joint member is incorporated into the cage, the concave portion formed on the outer spherical surface of the inner joint member is brought into contact with or close to the pillar portion of the cage, thereby inserting the convex portion of the inner joint member into the pocket of the cage. (See FIG. 8). By providing this concave portion, even if the axial dimension of the convex portion of the inner joint member is larger than the circumferential width dimension of the pocket, the convex portion of the inner joint member is prevented from interfering with the column portion and pocketed. Can be inserted inside.
また、継手が大きな作動角をとったとき、内側継手部材の凹部と保持器の内球面が対面する箇所では（図９参照）、内側継手部材の外球面の中間部近傍部位及び端縁近傍部位が、保持器の内球面に接触して支持する。これにより、高トルクが負荷された場合であっても、内側継手部材が保持器の内球面に強く食い込むことを防止できる。 Further, when the joint takes a large operating angle, at the location where the concave portion of the inner joint member and the inner spherical surface of the cage face each other (see FIG. 9), the intermediate portion vicinity portion and the edge vicinity portion of the outer spherical surface of the inner joint member Is in contact with and supports the inner spherical surface of the cage. Thereby, even if it is a case where high torque is loaded, it can prevent that an inner side coupling member bites into the inner spherical surface of a holder | retainer strongly.
請求項２の発明は、請求項１に記載の固定式等速自在継手において、前記内側継手部材の全ての外球面の軸線方向の中間部と一端縁の間に、凹部を設けたものである。 According to a second aspect of the present invention, in the fixed type constant velocity universal joint according to the first aspect, a concave portion is provided between an axial intermediate portion and one end edge of all outer spherical surfaces of the inner joint member. .
内側継手部材の外球面のうち、任意に選択した外球面の凹部を保持器の柱部に接触ないし接近させれば、内側継手部材の凸部を保持器のポケットに挿入することができる。請求項２の場合は、組付け性が向上し、内側継手部材の軽量化も図れる。また、請求項１の場合と同様に、内側継手部材が保持器の内球面に強く食い込むことを防止できる。 Of the outer spherical surfaces of the inner joint member, the convex portion of the inner joint member can be inserted into the pocket of the cage by making the concave portion of the outer spherical surface selected arbitrarily contact or approach the column portion of the cage. In the case of claim 2, the assembling property is improved and the weight of the inner joint member can be reduced. Further, as in the case of the first aspect, the inner joint member can be prevented from strongly biting into the inner spherical surface of the cage.

請求項５の発明は、請求項１又は２に記載の固定式等速自在継手において、前記凹部は、断面Ｖ字状である。 According to a fifth aspect of the present invention, in the fixed type constant velocity universal joint according to the first or second aspect, the concave portion has a V-shaped cross section.
請求項３〜５のように、凹部の断面形状は容易に変更可能である。 As in the third to fifth aspects, the cross-sectional shape of the recess can be easily changed.
本発明の固定式等速自在継手によれば、内側継手部材の凸部の軸線方向寸法がポケットの周方向幅寸法より大きい場合であっても、凸部をポケット内に挿入して内側継手部材を保持器に組み込むことができる。これにより、内側継手部材の案内溝の軸線方向寸法を延ばすことができ、継手の高作動角化を図れる。また、継手の高作動角、高トルク負荷時の内側継手部材の保持器への食い込み現象を防止して、継手の円滑な回転運動を維持することが可能となる。 According to the fixed type constant velocity universal joint of the present invention, even when the axial dimension of the convex part of the inner joint member is larger than the circumferential width dimension of the pocket, the convex part is inserted into the pocket and the inner joint member is inserted. Can be incorporated into the cage. Thereby, the axial direction dimension of the guide groove of an inner joint member can be extended, and the high operating angle of a joint can be aimed at. In addition, it is possible to prevent the inner joint member from biting into the cage when the joint is operated at a high operating angle and a high torque load, and to maintain a smooth rotational motion of the joint.

以下、本発明の具体的構成について説明する。図２は本発明に係る固定式等速自在継手の内輪の斜視図、図３は図２のＹ矢視図、図４は図３のＺ−Ｚ断面図である。図２〜図４に示すように、内輪２の案内溝２ｂ相互間の全ての外球面２ａに、凹部１１が設けてある。 Hereinafter, a specific configuration of the present invention will be described. 2 is a perspective view of the inner ring of the fixed type constant velocity universal joint according to the present invention, FIG. 3 is a view taken along the arrow Y in FIG. 2, and FIG. 4 is a ZZ sectional view in FIG. As shown in FIGS. 2 to 4, all the outer spherical surfaces 2 a between the guide grooves 2 b of the inner ring 2 are provided with recesses 11.
図４の要部を拡大した図５に示すように、上記凹部１１は、外球面２ａの軸線方向の中間部２０と、図５の右側の端縁２１の間、詳しくは右側の端縁２１寄りの部分に形成されている。この凹部１１を形成することにより、外球面２ａは、右側の端縁２１を含む小球面部１２と、中間部２０と左側の端縁２２を含む大球面部１３とを有する。なお、小球面部１２と大球面部１３は、同一球面上にある。 As shown in FIG. 5 in which the main part of FIG. 4 is enlarged, the recess 11 is formed between the intermediate portion 20 in the axial direction of the outer spherical surface 2a and the right edge 21 in FIG. It is formed in the close part. By forming the recess 11, the outer spherical surface 2 a has a small spherical surface portion 12 including a right edge 21 and a large spherical surface portion 13 including an intermediate portion 20 and a left edge 22. The small spherical surface portion 12 and the large spherical surface portion 13 are on the same spherical surface.
この場合、凹部１１は、軸線Ｘに対して、平行な面（平行面）１１ａと、直交する面（直交面）１１ｂとを有する断面Ｌ字状に形成されている。また、凹部１１の断面形状は、これ以外の形状であってもよい。例えば、図６に示すように、円弧面１１ｃに形成する場合や、図７に示すように、平行面１１ａと直交面１１ｂをＲ面１１ｄにて連結し、さらに平行面１１ａから端縁２１側へ傾斜面１１ｅを延設した断面Ｖ字状にしてもよい。凹部１１の形成方法は、切削加工や塑性加工など任意の形成方法を採用することができる。 In this case, the recess 11 is formed in an L-shaped cross section having a plane (parallel plane) 11a parallel to the axis X and a plane (orthogonal plane) 11b orthogonal to the axis X. Moreover, the cross-sectional shape of the recessed part 11 may be other shapes. For example, as shown in FIG. 6, when forming on the circular arc surface 11c, or as shown in FIG. 7, the parallel surface 11a and the orthogonal surface 11b are connected by the R surface 11d, and further from the parallel surface 11a to the edge 21 side. You may make it the cross-sectional V shape which extended the inclined surface 11e. The formation method of the recessed part 11 can employ | adopt arbitrary formation methods, such as cutting and plastic working.
以下、本発明の内輪を保持器に組み付ける方法について説明する。
内輪２の軸線が保持器４の軸線に対し９０°をなすように、内輪２を配置する。この状態で、内輪２の案内溝２ｂを保持器４の入口部４ｄに跨がせる（図１０参照）。跨がせた案内溝２ｂを中心に矢印Ａ方向に回転させて、内輪２の案内溝２ｂ相互間の凸部２ｃを保持器４のポケット４ａに挿入する。
Hereinafter, a method for assembling the inner ring of the present invention to the cage will be described.
The inner ring 2 is arranged so that the axis of the inner ring 2 forms 90 ° with respect to the axis of the cage 4. In this state, the guide groove 2b of the inner ring 2 is straddled over the inlet portion 4d of the cage 4 (see FIG. 10). The projecting portion 2 c between the guide grooves 2 b of the inner ring 2 is inserted into the pocket 4 a of the cage 4 by rotating in the direction of arrow A around the straddled guide groove 2 b.
図８は、内輪２の凸部２ｃを保持器４のポケット４ａに挿入した状態を示す。図８に示すように、内輪２の外球面２ａに形成した凹部１１を、保持器４の柱部１１に接触ないし接近させ、外球面２ａの大球面部１３をポケット４ａに挿入する。内輪２の凸部２ｃの軸線方向寸法Ｌがポケット４ａの周方向幅寸法Ｗより大きい場合であっても、凹部１１を設けたことにより、凸部２ｃを柱部１０との干渉を回避してポケット４ａ内に挿入できる。このようにして、内輪２を保持器４内へ入れ、内輪２を保持器４内で９０°回転させて球面係合させ組み付ける。 FIG. 8 shows a state where the convex portion 2 c of the inner ring 2 is inserted into the pocket 4 a of the cage 4. As shown in FIG. 8, the concave portion 11 formed on the outer spherical surface 2a of the inner ring 2 is brought into contact with or close to the column portion 11 of the retainer 4, and the large spherical portion 13 of the outer spherical surface 2a is inserted into the pocket 4a. Even when the axial dimension L of the convex part 2c of the inner ring 2 is larger than the circumferential width dimension W of the pocket 4a, by providing the concave part 11, the convex part 2c can be prevented from interfering with the pillar part 10. It can be inserted into the pocket 4a. In this way, the inner ring 2 is put into the cage 4, and the inner ring 2 is rotated 90 ° in the cage 4 to be engaged with the spherical surface and assembled.
また、組付け後、図９に示すように、本発明の継手が大きな作動角をとったとき、内輪２の凹部１１と保持器４の内球面４ｃが対面する箇所では、内輪２の外球面２ａの大球面部１３と小球面部１２が、保持器４の内球面４ｃに接触している。そして、この状態で高トルクが負荷された場合であっても、保持器４の内球面４ｃに大球面部１３と小球面部１２とで接触して支持しているので、内輪２が保持器４の内球面４ｃに強く食い込むことがない。 Further, as shown in FIG. 9, after the assembly, when the joint of the present invention takes a large operating angle, the outer spherical surface of the inner ring 2 is located at a location where the concave portion 11 of the inner ring 2 and the inner spherical surface 4c of the cage 4 face each other. The large spherical surface portion 13 and the small spherical surface portion 12 of 2 a are in contact with the inner spherical surface 4 c of the cage 4. Even when a high torque is applied in this state, the inner ring 2 is held in the cage because the large spherical surface portion 13 and the small spherical surface portion 12 are in contact with and supported by the inner spherical surface 4c of the cage 4. 4 does not dig into the inner spherical surface 4c.
以上、本発明の一実施形態について説明したが、本発明は上述の実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で、種々の変更を加え得ることは勿論である。前記凹部１１は、複数の外球面２ａのうち、少なくとも１つに設ければよい。また、図５において、凹部１１を、柱部１０外球面２ａの中間部２０と左側の端縁２２との間に設けてもよい。また、本発明の構造は、図１に示した固定式等速自在継手に限らず、あらゆる固定式等速自在継手に適用することができる。 As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention. The recess 11 may be provided in at least one of the plurality of outer spherical surfaces 2a. In FIG. 5, the concave portion 11 may be provided between the intermediate portion 20 of the outer spherical surface 2 a of the column portion 10 and the left edge 22. The structure of the present invention is not limited to the fixed type constant velocity universal joint shown in FIG. 1, and can be applied to any fixed type constant velocity universal joint.
