A retainer ring for a freewheel clutch comprises an annular disc and a plurality of sprag-guiding clips mounted on a radial face of the annular disc in a circumferential distribution about the disc axis. Each clip extends parallel to the disc axis and holds a sprag captive. Each clip has two parallel, circumferentially spaced legs extending from the radial disc face and being parallel to the disc axis. The legs extend along opposite sides of the circumferential surface of the sprag. Each clip further has a web interconnecting the clip legs at ends thereof remote from the radial face of the annular disc. The web extends along one of the end faces of the respective sprag.

Retainer ring for a freewheel clutch

A combination of a sprag clutch and a deep-groove ball bearing has a cage ring made of two identical radial halves. Each cage ring half has circumferentially spaced first recesses each accommodating and pivotally supporting a spring-biased sprag; circumferentially spaced alternating pockets for captively holding a bearing ball; and second recesses each nestingly receiving a bearing ball. The number of pockets and the number of second recesses in each cage ring half each equals one half the number of bearing balls in the ball bearing. The two cage ring halves are staggered with respect to one another to the extent of one bearing ball pitch, so that with any pocket on either cage ring half there is axially aligned a second recess in the other cage ring half.
