Abstract
A tripod roller for a constant velocity universal joint includes inner and outer rings separated by a set of rollers. During assembly of the tripod roller the rollers are assembled to one of the inner and outer rings and then the other of the inner and outer rings is moved axially into position. Then, a forming tool is applied to one of the rings, in a direction perpendicular to the roller axis, to create a securing region. The securing region prevents relative axial movement of the two rings during the assembly of the universal joint.
Claims17
A tripod roller for a constant velocity universal joint, the tripod roller comprising:
- an inner ring and an outer ring arranged coaxially to a tripod roller axis;
- and
- a plurality of rollers arranged so as to roll between the inner ring and the outer ring;
- and
- wherein a first of the inner ring and the outer ring being a securing ring having a securing region, wherein the securing region is designed as an embossing region or caulking region, wherein the securing region axially secures a second of the inner ring and the outer ring or at least one of the rollers in a form-fitting manner as a securing partner.
9-10. (canceled)
A constant velocity universal joint comprising:
- first and second rings arranged coaxially with respect to a tripod roller axis;
- and
- a plurality of rollers arranged to roll between the first and second rings;
- and
- wherein the first ring has a securing region which axially secures the second ring in a form-fitting manner.
A method of assembling a tripod roller for a universal joint, the method comprising:
- arranging a plurality of rollers between an inner ring and an outer ring to facilitate relative rotation about a roller axis;
- and
- using a forming tool in a direction perpendicular to the roller axis to create a securing region on one of the inner ring and the outer ring, thereby axial securing the inner ring and outer ring to one another.
