Abstract
A retainer for sprags in an overrunning clutch is provided. The retainer is disposed between the inner and outer races of the clutch. The retainer includes first and second rings disposed about an axis and axially spaced from one another and a plurality of cross bars extending between the first and second rings. The plurality of cross bars are circumferentially spaced and define a plurality of openings. Each opening is configured to receive one of the sprags disposed between the inner and outer races of the clutch. At least the cross bars of the retainer are made from a tool steel, preferably S7 tool steel. The construction of the retainer increases the abrasion resistance of the retainer and extends the service life of the clutch.
