Abstract
A joint for the angularly adjustable drive-connection of a cylinder block and a driveshaft of a hydrostatic bent axis piston unit. The joint has a shank which is rotatable about its longitudinal axis defining a joint axis, on both ends of the shank roller carriers project radially and basically perpendicular to the joint axis. On each roller carrier a roller is provided rotatable around a roller axis. The rollers are secured in axial direction against slipping-off of the roller carriers by means of an embossed area located axially outside of the roller on the respective distal end portion of the roller carrier.
Claims23
A synchronizing joint for an angularly adjustable drive-connection of a cylinder block and a driveshaft of a hydrostatic bent axis piston unit,
- wherein the synchronizing joint has a shank which is rotatable about its longitudinal axis defining a joint axis,
- wherein, on both ends of the shank, roller carriers project radially and basically perpendicular to the joint axis,
- wherein on each roller carrier a roller is provided rotatable around a roller axis, and
- wherein the rollers are secured in axial direction against slipping-off of the roller carriers by means of an embossed area located axially outside of the roller on the respective distal end portion of the roller carrier,
- wherein the embossed area includes material added to the distal end portion of the roller carrier.
A universal joint for an angularly adjustable drive-connection of two driveshafts,
- having a shank which is rotatable about its longitudinal axis defining a joint axis,
- wherein on at least one end of the shank a roller carrier projects radially and basically perpendicular to the joint axis,
- wherein on the at least one roller carrier a roller is provided rotatable around a roller axis,
- wherein the roller is secured in axial direction of the roller axis against slipping-off of the roller carrier by means of an embossed area located axially outside of the roller on the distal end portion of the roller carrier,
- wherein the roller carriers are integrally formed with the shank, and
- wherein the embossed area is brought up by means of laser application to locally increase the diameter of the roller carrier.
A universal joint for an angularly adjustable drive-connection of two driveshafts,
- having a shank which is rotatable about its longitudinal axis defining a joint axis,
- wherein on at least one end of the shank a roller carrier projects radially and basically perpendicular to the joint axis,
- wherein on the at least one roller carrier a roller is provided rotatable around a roller axis, and
- wherein the roller is secured in axial direction of the roller axis against slipping-off of the roller carrier by means of an embossed area located axially outside of the roller on the distal end portion of the roller carrier,
- wherein the roller carriers are integrally formed with the shank, and
- wherein the embossed area includes material added to the distal end portion of the roller carrier.
