摘要： A constant velocity universal joint smoothly rotates under a high operating angle and large torque and reduces an excessive load applied to the cage. The universal joint includes an outer joint member having an inner spherical surface with multiple track grooves and an inner joint member having an outer spherical surface with multiple track grooves paired with the track grooves of the outer joint member. The universal joint also includes multiple balls interposed between the track grooves of the inner and outer joint members to transmit torque and a cage interposed between the outer joint member and the inner joint member to retain the balls. A tapered relief portion retracted with respect to the outer spherical surface is formed with low curvature at a back end portion of the outer spherical surface of the inner joint member to be smoothly continuous with the outer spherical surface.

摘要： Automatic installation of a circlip is facilitated even when an axial length (inner race width) of a protrusion of an inner race is reduced. An inner race is installed in a constant velocity universal joint for transmitting torque while allowing angular displacement between itself and an outer race, with a shaft being inserted in a shaft hole formed in an inner bore to be spline-fitted thereto so as to be prevented from coming off by virtue of the circlip. A two-step chamfer having different chamfer angles is provided at a shaft insertion side end portion of the shaft hole. The two-step chamfer includes a first chamfer section situated on a shaft hole opening side and a second chamfer section provided on the side opposite to the shaft hole opening so as to be continuous with the first chamfer section. The chamfer angle α of the first chamfer section is set larger than the chamfer angle β of the second chamfer section.

摘要： It is made easy to design so that the sliding resistance, when subjected to an impact in the axial direction, is kept within a prescribed value. A constant velocity universal joint is provided, which has track grooves extending in the axial direction on the outer circumference surface of the inner ring, and formed in an intersecting arrangement, and which also embeds balls in these track grooves. In this constant velocity universal joint, the cross-sectional shape of the track groove of the inner ring is constituted by a Gothic arch portion which is a Gothic arch shape up to a location that exceeds a contact point where the groove angular contacts with the ball, and a straight-line portion which is formed continuously with the Gothic arch portion, between the location exceeding the contact point and a shoulder portion of the track groove, and which extends in the direction of the tangent line at the location that exceeds the contact point.
