    Abstract: A universal joint bearing assembly (20) incorporates an inventive thrust washer (30) molded from plastic. The plastic thrust washer (30) eliminates the metal galling and metal debris that have been found in prior art universal joint bearings. A support notch (38) is formed at radially outer surfaces to support an inner end (40) of needle bearings (28). Resilient members (34) bias the notch (38) against the needle bearings (28) such that the needle bearings (28) are supported on the notch (38) and against a seal (26) at the outer end (42) of the bearing cup (22). The resilient members (34) are compressed when the universal joint is assembled such that the needle bearings (28) operate properly. A central dome extension (36) on the thrust washer (30) insures that the thrust washer (30) is not improperly mounted within the bearing cup (22). An outer face of the thrust washer (30) is formed at an angle (A) such that central portion (50) extend further towards the trunnion (24) than radially outer portions. In a method of assembling a bearing according to the present invention, the thrust washer (30) is initially placed within a bearing cup (22) and the needle bearings (28) are then mounted within the bearing cup (22) as is the seal (26). The thrust washer (30) biases the needle bearings (28) such that they are supported between the thrust washer (30) and a seal (26). The bearing may then be shipped. When the universal joint is finally assembled, the trunnion (24) compresses the resilient members (34). At that time, the needle bearings (28) are free to move axially and the universal joint will operate properly.

    Abstract: An end of life indicator for a universal joint comprises an indicator member (34) that monitors the temperature of the cross member (22) of the universal joint. As the universal joint approaches the end of its life, the cross member (22) exceeds expected temperatures as the bearings begin to wear. At a temperature above the typical operational temperature expected with a properly functioning universal joint, but below the temperature wherein the universal joint could be damaged or seized, a portion of the temperature indicator (39) melts allowing the indicator (34) to move to the actuated position (see Fig. 4). An operator will be able to visually identify the universal joint as approaching the end of its life. In one preferred embodiment, the indicator includes a plug (39) at a position spaced forwardly of the indicator piston (34), with the plug (39) holding the piston (34) at the non-actuated position. When the plug (39) melts, the indicator (34) is spring (35) biased to an outwardly actuated position where the operator will be able to visually identify an actuated indicator.

    Abstract: A bearing support member (12) has two support arms (34, 36) extending in opposite directions along an axis and is adapted for mounting about a stud means (20). A bearing cup (16) is fixed to the rocker arm (10), extending over each support arm. Rolling members (14) are provided within an annulus formed between the support member and the bearing cups such that the rocker arm is free to oscillate rotatably with respect to the bearing support member. The bearing cups have a bottom surface (48) forming an interference fit, axially, with an end surface of the bearing support member such that a preload is applied to the bearing support arm to reduce and control axial play. A protrusion (42) and cutouts facilitating the preload and a method of assembly are also disclosed.
