摘要： A fixed type constant velocity joint includes an outer ring (1), an inner ring (2), torque transmitting balls (3), a cage (4), and a pre loading mechanism in which either a pressing section for axially applying an elastic pressing force or a receiving section for receiving the pressing force from the pressing section is disposed in the cage (4), the other being disposed in the inner ring (2). The axial clearance between the inner ring (2) and the cage (4) is greater than the axial clearance which is due to the radial clearance of the track, and the axial clearance which is produced by the radial clearance of the track is 2.5-6.5 times as large as the radial clearance of the track. Further, the center of the outer spherical surface (2b) of the inner ring (2) is shifted to the spread side of the ball tracks (1a, 2a) over the center of the inner spherical surface (4b) of the cage, thereby improving the cross operation.
