Embodiment Construction

[0080] figure 1 A cross-sectional view of an exemplary embodiment of the cage 1 is schematically shown. The cage 1 comprises a base body 5 having a cylindrical shape, the peripheral surface of which is curved outward in a spherical shape. Such a base body 5 generally has a material thickness 14 in the range of 2.5 to 6.0 mm. The shown embodiment of the cage 1 is provided with a plurality of grooves 2 on the circumference. These grooves are used to accommodate the rolling elements of the universal joint. Here, the cage has six (6) grooves 2, but could also be four (4) or eight (8). Usually each groove 2 is shaped such that the rolling elements therein can always move sufficiently under load. The positioning of a plurality of rolling elements in one groove 2 is also realized. A different configuration of the ball cage 1 can then be used.

Abstract

A cage having a plurality of cutouts for receiving rolling bodies of a joint, wherein the cage comprises a quenched and tempered steel, and the entire cage has a substantially uniform ductility over its cross section without surface hardening.

Description

technical field [0001] The invention relates to a ball cage with a plurality of grooves for accommodating rolling bodies of a universal joint. In addition, a method for processing the ball cage is provided. Background technique [0002] In particular, the invention relates to cages for constant velocity ball swivel joints, such as are used in automobile construction. Such a joint has a joint outer part and a joint inner part, in which a plurality of substantially longitudinally extending ball tracks are arranged. Between the joint outer part and the joint inner part, there are balls for torque transmission, wherein the positioning of the balls is ensured by a ball cage arranged between the joint outer part and the joint inner part. The cage has multiple cage windows for the balls, thereby restricting the direction of movement of the balls in the axial direction. [0003] Taking into account the different types of joints, the invention relates in particular to the cages of...
