Abstract
A ratchet-type one-way clutch mechanism . The mechanism has an inner race member with a plurality of notches , an outer member with a plurality of pockets , a plurality of pawl members positioned in the pockets for engagement with the notches, and spring biasing members for biasing the pawl members toward engagement. The outer member can be a stator member or an outer race member . Retainer members retain the pawls axially in the pockets. Bearing surfaces on the inner race member, outer member and retainer member provide bearing support. Large radii R on the pawl members and pawl pockets reduce wear and minimize the cost of secondary machining operations. The lower surfaces of the pawl members are curved and the curvature R can be larger than the curvature R of the inner race member. Also, the inner race members can be made of a plurality of thin disk members stacked and secured together, with various types of disk members being utilized in the stack.
