この発明は、相変わる２軸の相互間において均一な角速
度でトルクを伝達する場合に使用される等速ジヨイント
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a constant velocity joint used when transmitting torque at a uniform angular velocity between two changing axes.
この種等速ジヨイントは、第９図に示すように、外輪１
と、内輪２との間にボール３およびそのボール３を保持
するケージ４を組込み、上記ボール３を介して外輪１と
内輪２の相互間においてトルクの伝達を行なうようにし
ている。This type of constant velocity joint has an outer ring 1 as shown in Fig. 9.
A ball 3 and a cage 4 for holding the ball 3 are installed between the outer ring 1 and the inner ring 2, and torque is transmitted between the outer ring 1 and the inner ring 2 via the ball 3.
また、外輪１の内径面をケージ案内面５とし、そのケー
ジ案内面５をジヨイント中心Ｏ０に曲率中心をもつ球面
としである。一方、内輪２の外径面をケージ案内面６と
し、そのケージ案内面６もジヨイント中心Ｏ０に曲率中
心をもつ球面とし、各ケージ案内面５．６でケージ４の
球面状外周面および球面状内周面を案内している。Further, the inner diameter surface of the outer ring 1 is a cage guide surface 5, and the cage guide surface 5 is a spherical surface having a center of curvature at the joint center O0. On the other hand, the outer diameter surface of the inner ring 2 is a cage guide surface 6, and the cage guide surface 6 is also a spherical surface having a center of curvature at the joint center O0. It guides the inner circumferential surface.
さらに、外輪１のケージ案内面５および内輪２のケージ
案内面６にボール３の移動を案内するトラック溝７．８
を設け、そのトラック溝７の曲率中心Ａとトラック溝８

、ボール３およびケージ４の回転を制御し、ボール３の
位置を常に外輪１の軸芯と内輪２の軸芯でなす角の２等
分面上にあるようにして回転数およびトルクの変動を防
止している。Furthermore, track grooves 7.8 for guiding the movement of the balls 3 on the cage guide surface 5 of the outer ring 1 and the cage guide surface 6 of the inner ring 2 are provided.
, and the center of curvature A of the track groove 7 and the track groove 8
Each of the centers of curvature B is offset from the joint center 0° by an equal distance to the left and right, and by this offset, the rotation of the balls 3 and the cage 4 is controlled, and the position of the balls 3 is always aligned with the axis of the outer ring 1 and the inner ring. It is placed on the bisecting plane of the angle formed by the two axes to prevent fluctuations in rotational speed and torque.
等速ジヨイントは、上記のように、外輪１のトラック溝
７の曲率中心Ａと内輪２のトラック溝８の曲率中心Ｂを
ジヨイント中心０゜に対して○。Ａ１０゜Ｂだけオフセ
ットしであるため、各トラック溝７．８は奥に至るに従
って溝深さが次第に浅くなる。As mentioned above, in the constant velocity joint, the center of curvature A of the track groove 7 of the outer ring 1 and the center of curvature B of the track groove 8 of the inner ring 2 are set ○ with respect to the joint center 0°. Since the track grooves 7.8 are offset by A10°B, the depth of each track groove 7.8 becomes gradually shallower toward the back.
このため、第１０図に示すように、等速ジヨイントが大
きく作動角をとると、ボール３はトラック溝７．８の浅
い奥側に移動する。Therefore, as shown in FIG. 10, when the constant velocity joint takes a large operating angle, the ball 3 moves to the shallow depth of the track groove 7.8.

トラック溝７．８のエツジ部を乗り上げ、その乗り上げ
によってボール接触点より塑性流動を越し、第１２図に
示すような盛り上がり９が生じる。Generally, in constant velocity joints, the hardness of the inner diameter surface of the outer ring 1 and the outer diameter surface of the inner ring 2 is approximately Hac5B to 63 by performing surface treatment such as carburizing and quenching. If an excessive load is applied when transmitting rotational torque at which the speed joint takes an extremely large operating angle, the ball 3 located at the shallow part of the track groove 7.8 will ride on the edge of the track groove 7.8, and as a result of this riding. The plastic flow is exceeded from the ball contact point, and a bulge 9 as shown in FIG. 12 is generated.
通常、内輪２におけるトラック溝８の両側面とケージ案
内面６の交差部には、第１１図に示すように面取り１０

あるため、塑性流動による僅かな盛り上がり９はその面

な盛り上がり９に対してはこれを吸収することができな
い。Usually, chamfers 10 are formed at the intersections between both side surfaces of the track groove 8 and the cage guide surface 6 in the inner ring 2, as shown in FIG.
On the other hand, since the outer ring 1 is also provided with a chamfer, the slight bulge 9 due to plastic flow can be absorbed by the clearance formed between the chamfer 10 and the cage 4. The chamfer 10 cannot absorb the large bulge 9.
このため、上記盛り上り量（ΔＲ）がケージ案内面６と
ケージ４のクリアランスを越えた場合にケージ４に引っ
かかりが生し、作動性に悪影響をを及ぼす。For this reason, when the amount of swelling (ΔR) exceeds the clearance between the cage guide surface 6 and the cage 4, the cage 4 gets caught, which adversely affects the operability.
このような不都合の解消を図るには、第１１図の鎖線Ｃ
で示すように、面取り角度を変えないで面取り１０を大

一つの方法であるが、この場合には、トラック溝８の溝
深さが浅くなるため、負荷容量が減少する問題が生じる
。In order to solve this inconvenience, the chain line C in Fig.
As shown in , one method is to increase the chamfer 10 without changing the chamfer angle and absorb the bulge 9 with the chamfer 10, but in this case, the groove depth of the track groove 8 becomes shallower. Therefore, a problem arises in that the load capacity decreases.
この発明の課題は、負荷容量を減少させることなく、し
かもケージの移動に悪影響を与えない範囲に盛り上がり
を抑えることができるようにした等速ジツイントを提供
することである。An object of the present invention is to provide a constant-velocity pivot point that can suppress swelling within a range that does not adversely affect the movement of the cage without reducing the load capacity.

た構成を採用したのである。In order to solve the above-mentioned problems, in the present invention, a straight line connecting the chamfering starting point of the track groove side surface and the center of the track groove at least on the back side where the groove depth is shallow and the track groove that guides the movement of the ball. The angle formed by the center line of the track groove is 70" or more, and the chamfer angle formed by the center line of the track groove and the straight line connecting the chamfer starting point of the side surface of the track groove and the chamfer starting point of the cage guide surface is 86° or more. We adopted this configuration.

上がりを吸収することができる。With the above configuration, the flat length of the chamfer can be made longer than the conventional chamfer while keeping the chamfer starting point on the side surface of the track groove the same as that of the conventional chamfer, so the clearance between the chamfer and the cage can be increased. The clearance becomes larger and can absorb the bulge formed at the ball contact point.
以下、この発明の実施例を第１図乃至第８図に基づいて
説明する。Embodiments of the present invention will be described below with reference to FIGS. 1 to 8.

ランスによって吸収することができる。In the present invention, the chamfer starting point 1 on the side surface of the track groove 8 is
2 is the same as the conventional one, and only the chamfer angle θ2 is made larger than the conventional one, so that the clearance formed between the chamfer 10 on the back side of the inner ring and the cage 4 can be made larger than that of the conventional one. As a result, when the joint takes a large operating angle to transmit torque, the bulge caused by the ball 3 riding on the joint can be absorbed by the clearance.
