ABSTRACT:
A sprag clutch utilising the principles of U.S. Pat. No. 3,651,908 has an improved energising spring arrangement in which the individual sprag energising springs are mounted on intermediate portions of bars forming part of the sprag retainer assemblage. The bars define with end ring parts of the retainer, separate compartments, one for the outer end of each sprag, end portions of the bars acting to position the sprags circumferentially, and the energising springs extend inwardly from the bars. The arrangement allows more sprags to be accommodated in a given diameter and, conveniently, the retainer is made in two identical annular parts which clip together.
