Abstract: A universal joint assembly having an inner and an outer joint member with torque transmitting means therebetween is formed with a drive shaft attached to the inner joint member within an axially slotted bevelled end portion formed on an extension of the inner joint member. The inner member has threaded means formed on a cylindrical outer wall thereof and by threaded engagement of a nut about the end of the inner member extension, the drive shaft is releasably engaged and clamped in the inner joint member in a manner facilitating this assembly. The outer wall of the inner joint member is also formed with a recess within which one side of a sealing boot may be secured.

Abstract: In a bearing arrangement for universal joints, a shaft fork has a pair of laterally spaced arms each supporting a roller bearing in a bore. Located between the arms is a cross joint member which has a pin on each end extending into the roller bearing in the bore of the adjacent arm. Each roller bearing has an outer race with its outer surface contacting the surface of the respective bore. The end of the outer surface facing toward the opposite arm is threaded and a support ring is threaded onto it. The support ring bears against an end surface of the adjacent arm which faces toward the opposite arm. The support ring is adjustable and can be locked in position relative to the arm of the shaft fork by a safety bolt.
