Ball sliding joint for joint shaft, has fit between balls and ball grooves varied based on axial displacement of joint outer part such that balls are pressed higher in end region of axial displacement than adjacent main operation region
摘要
<p>The joint has a joint outer part (2) with ball grooves (4) formed at inner area and a joint inner part (3) with ball grooves (5) formed at an outer area. Balls (6) stand in contact with the ball grooves for transferring of turning moments. A fit between the balls and the ball grooves of the joint outer part and the joint inner part is varied based on an axial displacement of the joint outer part relative to the joint inner part such that the balls are pressed higher in an end region of an axial displacement than an adjacent main operation region.</p>
