ABSTRACT:
A universal joint (100) comprising a spider (102) having a trunnion (104) projecting outward from the spider is provided. A bearing (108) is disposed over a distal end of the trunnion with a lubricant passageway (110) disposed within the trunnion and in fluid communication with the bearing. A lubricant pressurizing system (112) is incorporated within the spider to bias or urge the lubricant through the lubricant passageway and toward the bearing. The trunnion may be tapered along its length and an outer edge (366) of the end of the trunnion may be radiused. The trunnion and/or bearing may further include a load carrying surface (114and158) comprised of a wear resistant material. The load carrying surface may be smooth or textured to retain a lubricant thereupon. The spider may include a plurality of cross grooves (126) and/or clearance radii (128) to aid in installation into the yoke.
