Abstract: An improved seal (10) for use in a universal joint (11) having an elastic seal ring (23) compressed between a pair of right circularly cylindrical sleeves (24, 25). The seal ring is bonded to the sleeves. The sleeves are adapted to have press-fitted relationship with association portions of the universal joint, such as the journal trunnion (12) and the bearing retainer (14). In one form, the elongated extent of the sleeves is parallel to the axis (15) of the journal trunnion (12) and in a modified form, the sleeves (124, 125) extend perpendicularly thereto. In each form, a portion of one of the sleeves is disposed adjacent the inner end of the needle bearings (22, 122) so as to limit axial movement thereof. The sleeves are bonded to the seal ring so as to preclude sliding movement therebetween while yet permitting limited axial play in the universal joint thereby to provide long troublefree life of the seal.

Abstract: An improved seal (40) for use in a universal joint structure (10). The seal includes a C-shaped seal ring (37) which is loaded into sealing engagement with an associated bearing cap (29, 30, 31, 32) by a load ring (43) compressively nested within the C-shaped seal ring. The leg (46) of the seal ring sealingly engages the bearing cap under a controlled load to provide an improved oil seal. The arrangement of the seal is coordinated with the allowable play of the trunnions (13, 14, 15, 16) of the joint structure so as to assure positive sealing engagement of the seal ring as a result of the loading of the load ring over the entire range of play movement permitted in the joint structure. The trunnions may be journaled in the bearing caps by suitable roller bearings (35) which may effectively further limit the play so as to limit sliding movement as well as axial deflection of the seal rings for further improved sealing in the joint structure. In one form the leg of the seal ring sealingly engaging the bearing cap has an effective sealing engagement therewith of approximately one-half the radial extent of the leg.

Abstract: A tripod constant velocity universal joint (22) having an annular outer member (24), an inner member (26) and three multiple component rollers (28). The interior surface of the outer member (24) has three longitudinal lobes (34) forming opposing pairs of parallel longitudinal guideways (36) which are engaged by the multiple component rollers (28). The inner member (26) is centrally positioned within the outer member (24) and has three trunnions (40) extending radially into the three longitudinal lobes (34). A multiple component roller (28) is pivotally attached to each of the trunnions (40). Each multiple component roller (28) has oppositely disposed pairs of elongated rollers (50), each of which engages an adjacent guideway (38) corresponds to its trunnion. The axis of rotation (54) of the elongated rollers (50) is substantially perpendicular to its adjacent guideway (38) each elongated roller (50) is mounted such that it can be axially displaced along its axis of rotation (54).

Abstract: A power transmission device which includes trunnion and bearing sets for transferring power from a power generating unit to an operating unit. In the preferred embodiment of the invention, a cross (36) is provided with a plurality of trunnions (39, 41, 43, 45) which define transfer surfaces (38, 40, 42, 44). A bearing member in the form of a cup (86) is provided for each of the transfer surfaces (38, 40, 42, 44). The bearing cup (86) is defined by a plurality of internal bearing surfaces (94) which are integral with the bearing cup sidewall (88) and which contact the transfer surfaces (38, 40, 42, 44) of the cross (36). The bearing surfaces (94), in the preferred embodiment, are semi-circular in cross-section and make bearing contact with the essentially cylindrical transfer surface of the cross. The bearing cup (86) is preferably fabricated using powder metallurgy techniques which advantageously form the integral bearing surfaces within the cup, thereby eliminating the necessity for the use of balls or needles in the cup.
