摘要：A ball bushing for mounting on a shaft is disclod which is freely movable relative to the shaft in both axial directions as well as in one direction of rotation and which is sluggishly movable in the cond direction of rotation, but without locking. The ball bushing includes a sleeve made of a deforma
ble material. Clod channels are defined in the sleeve, each having two axially extending portions connected at both ends by curved portions. One axially extending portion contains a row of load- bearing balls, adjacent to which is a steel needle. The steel needle is positioned so that the center point of each of the load-bearing balls is positioned to one side of the line through the axes of the shaft and the needle, that side being toward the cond axially extending portion of the same clod channel. Therefore, the lines connecting the axes of the shaft and needle to the center point of each of the load-bearing balls form an angle, the angle being preferably between 174° and 178. degree.. The angle may be constant for all the load-bearing balls, or may decrea toward the ends of the needle. The needle may have a diameter which tapers down from its center towards its ends.
