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,
- wherein bores in the roller carriers extend transversely from the longitudinal bore in the shank, and
- wherein radial bores extend from the transversely extending bores in the roller carriers such that lubrication fluid from the longitudinal bore in the shank is capable to be guided to the rollers.
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,
- wherein bores in the roller carriers extend transversely from the longitudinal bore in the shank, and
- wherein radial bores extend from the transversely extending bores in the roller carriers such that lubrication fluid from the longitudinal bore in the shank is capable to be guided to the rollers.
