Abstract

A bearing assembly operatively interposed between a shaft and a housing having said shaft axially movably mounted therein for torque transmission therebetween includes a ball bushing inserted into a bushing receiving bore in the housing and guided through ball rings in ball races, with at least one of said ball rings being a load-transmitting ring including a load-transmitting ball ring section which rests radially inwardly against the shaft and radially outwardly against an external support surface defined by the ball bushing. The load bearing ball ring section of the at least one ball ring engages a race groove in the shaft on the shaft side of the ball ring and it engages a race groove of a bearing plate mounted in the ball bushing on the ball bushing side of the ball ring in a manner to transmit torque therebetween. The bearing plate may be pressed radially inwardly by means of a clamping device which presses against the ball bushing through contact surfaces which are oriented to intersect resultant planes generated by torque transmitting forces transmitted through the torque transmitting ball ring which are parallel to the bushing axis at an angle to insure a self-locking acti…
