A dielectric insulating insert assembly arranged to be positioned between a drive shaft and a driven shaft of a motorised drive assembly, the insert assembly comprising a plurality of elongate pins of dielectric material configured to engage, respectively, with the drive shaft and the driven shaft in torque transfer engagement, the pins providing a dielectric barrier between the drive shaft and the driven shaft.

A bent-axis hydraulic pump motor includes: a cylinder block, a retainer plate; and a constant velocity joint, which includes an inner joint element; an outer joint element; and a plurality of balls interposed between block-side ball grooves and shaft-side ball grooves to transmit torque between the cylinder block and the retainer plate, so that all block-side groove planes, which include respective extending axial lines of the block-side ball grooves and the inclined rotation center, are inclined with respect to an axial center of a center shaft and all drive shaft-side groove planes, which include respective extending axial lines of the shaft-side ball grooves and the inclined rotation center, are inclined with respect to an axial center of a drive shaft such that loads applied to a cage in an axial direction from the balls are balanced.

A constant velocity universal joint has a large-diameter mounting portion fastened and fixed by a first fastening clamp onto a boot receiving portion of an outer joint member, and a small-diameter mounting portion fastened and fixed by a second fastening clamp onto a boot receiving portion of a shaft. A circumferential clamp groove to which the first fastening clamp is fitted is formed in an outer peripheral surface of the large-diameter mounting portion. A protruding portion is formed at a boot outer side end portion of an inner peripheral surface of the large-diameter mounting portion. A recessed portion to which the protruding portion is fitted is formed in the boot receiving portion being a cylindrical surface of the outer joint member. A projection is formed in the vicinity of a boot inner side of the recessed portion.

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.

A joint arrangement includes an outer joint component, an inner joint component, a cage and at least two balls located between the outer and inner joint component and in openings of the cage. The balls run in ball recesses, while at least two are in a mechanical contact with pressing devices, which are adapted for holding the respective balls in a radially flexible position relative to one of the inner joint component, the outer joint component and the cage and for pressing the respective balls into the corresponding recesses.

A method of manufacturing an outer joint member of a constant velocity universal joint includes forming cup and shaft members of medium carbon steel, the cup member being manufactured by preparing a cup member having cylindrical and bottom portions being integrally formed, and a fitting hole formed in a thick portion of the bottom portion, the shaft member being manufactured by preparing a shaft member having a fitting outer surface formed at an end portion of the shaft member to be joined to the bottom portion of the cup member, and fitting the fitting hole of the cup member to the fitting outer surface of the shaft member. The method also includes welding the cup and shaft members from an inner side of the cup member to a fitted portion between the cup and shaft members.
