Abstract
A constant velocity universal joint designed as a fixed or plunging joint permits the use of balls with a larger diameter, with the selectable shaft diameter not being adversely affected by using such balls with a larger diameter. The objective is achieved in that, in a first operation, the inner joint part is assembled with the cage while being pivoted at an angle of up to 90.degree. and that, subsequently, in a second operation, the inner joint part is welded to an associated shaft.
Claims10
A method of assembling a constant velocity universal joint having an outer joint part with a plurality of circumferentially distributing outer running grooves, an inner joint part having a plurality of inner running grooves corresponding to said outer running grooves, a cage arranged between said inner joint part and said outer joint part having a plurality of windows corresponding to said plurality of inner and outer running grooves and a torque transmitting ball received in each of said plurality of corresponding inner and outer grooves and windows, said method comprising the steps of:
- assembling said inner joint part and said cage at a relative pivot angle of up to 90.degree. to form an inner joint assembly;
- and
- welding said inner joint part of said inner joint assembly to a shaft.
A method of assembling an inner joint part, a cage and a shaft of a universal joint, said method comprising the steps of:
- assembling said inner joint part and said cage at a relative pivot angle of up to 90.degree. to form an inner joint assembly;
- and
- welding said inner joint part of said inner joint assembly to said shaft.
