CONSTANT VELOCITY FIXED JOINT

摘要

The invention relates to a constant velocity fixed joint comprising an outer joint part (2) having a plurality of ball bearing races (4) on the inner circumference, an inner joint part (3) having a plurality of ball bearing races (5) on the outer circumference, a cage (10) having a plurality of windows (13) disposed between the outer joint part (2) and the inner joint part (3), and ball bearings (6) each disposed in a window (13) of the cage (10) and engaging with the ball bearing races (4, 5) of the outer joint part (2) and the inner joint part (3) for transmitting torque. Recesses (15) adjoin the ball bearing races (4, 5) of the outer joint part (2) and/or the inner joint part (3), and are expanded radially and/or in the circumferential direction relative to the ball bearing races (4, 5) of the outer joint part (2) or the inner joint part (3), in order to enable deflection of the affected ball bearings (6) relative to an imaginary extension of the ball bearing races (4, 5) in the radial direction and/or the circumferential direction when the joint is excessively bent into a position for installing the ball bearings. The fracture strength of a constant velocity fixed joint designed for large operating bend angles can hereby be considerably increased. The installation of the ball bearings (6) is also simplified.
