A cam roller for a pod joint, comprising an inner rolling path and an outer ring unit, wherein a rolling path for the rolling on a bell housing section is arranged on an outer side of the outer ring unit, a plurality of rolling elements, wherein the plurality of rolling elements are arranged between the inner rolling path and the outer ring unit, and a cage device, wherein the plurality of rolling elements are arranged within the cage device, wherein the cage device includes at least one separating point in circumferential direction.

A tripod constant-velocity joint includes: an outer joint member having a cavity elongated in a longitudinal direction and three roller tracks; an inner joint member having a center body and three journals outwardly radially protruded from the center body; and three roller assemblies respectively coupled to the journal in a state of being respectively disposed in the roller tracks. The respective roller assembly comprises: an inner race which is connected to the journal and is provided with a first inner ball groove and a second inner ball groove on both lateral sides thereof; a first ball array and a second ball array respectively having a plurality of balls which are respectively disposed in the first inner ball groove and in the second inner ball groove; and a ball cage which restricts movements of the first ball array and the second ball array in a longitudinal direction thereof.

A gimbal joint may employ a plurality of wear sleeves, each disposed between a pin or pin receptive bore of a first structure and a corresponding bore or pin of a second structure and between another pin or bore of the second structure and a corresponding bore or pin of a third structure. Each of these structures may be adapted to rotate in a single plane, with one structure adapted to also tilt about a first axis, and one other structure adapted to tilt about a second axis. Each integral flanged wear sleeve may comprise a right circular hollow cylindrical body portion, which may be interiorly sized to be retained on one of the pins and externally sized to be retained in one of the pin receptive bores, and a flange portion may radiate from one end of the cylindrical body portion.

A tripod joint can include a joint outer part with a first longitudinal axis and a cavity running parallel to the first longitudinal axis with an open end, three recesses running parallel to the first longitudinal axis being formed in the joint outer part, and a joint inner part with a second longitudinal axis., The tripod joint can include at least one central body on which three trunnions are formed with trunnion axes extending radially from the second longitudinal axis, wherein a roller body is arranged on each of the trunnions, which roller body has at least one outer ring and an inner ring rotatable therewith about a common axis of rotation, as well as bearing bodies arranged between the outer ring and the inner ring; wherein each roller body is movably received in the recesses along the first longitudinal axis.

The present disclosure relates to an angle-adjustable tripod universal joint, which includes a tripod, 3 rollers and a universal joint outer part, an inner wall of the universal joint outer part is provided with 3 roller track, each roller is disposed in the roller track and rolls along the roller track, each spherical shaft head on the tripod is rotatably disposed in an inner cavity of the roller, the inner wall of the roller track is provided with a guiding groove, the peripheral shape of the roller is cylindrical, a bottom surface of the guiding groove is a plane surface, two side surfaces of the guiding groove are flat surfaces perpendicular to the plane surface, a part of the peripheral surface of the roller is inserted into the guiding groove, and the peripheral surface of the roller is tangent to the plane surface.

A constant velocity joint includes: an outer joint member having a raceway groove; an inner joint member having a leg shaft; a roller that is able to roll on the raceway groove; and a needle bearing that supports an inner periphery of the roller such that the inner periphery of the roller is able to rotate with respect to the leg shaft. The leg shaft includes: a roll portion that supports the needle bearing; a contact portion that is able to contact an end face of the needle bearing, the end face facing a first side in the direction of a central axis of the needle bearing; and a recess portion formed between the roll portion and the contact portion, in a position where the recess portion is recessed from a space in which the needle bearing is disposed.

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.

A tripod roller is used in a tripod joint having a joint outer part and a joint inner part with three supporting pins. The tripod roller is placed on at least one of the three supporting pins. The tripod roller includes an inner ring, an outer ring, and may include an intermediate ring. The inner ring is placed on a supporting pin. An outer surface of the outer ring bears against the joint outer part. At least one interface between the sliding pin, the inner ring, the intermediate ring, if present, and the outer ring forms a sliding bearing.

In a tripod type constant velocity universal joint 1 of a double roller type, R/PCD?0.0850 and t/PCD?0.145, where PCD is a pitch circle diameter of a roller guide surface 6 of an outer joint member 2. R is a radius of curvature at an intermediate portion between a body portion 31 and a leg shaft 32 of a tripod member 3, and t is a minimum distance from a large-diameter portion 34a of a spline 34 of the tripod member 3 to an intermediate portion 33.
