Roller clutch energizing spring with protected pleats

摘要

An accordion type roller clutch energizing spring protects its radially directed pleats from wear against the cage side rails by taking advantage of the side thrust that occurs when a spring of that type without squared off end leaves is tipped in order to fit it into the pocket. At least one end leaf is lengthened so as to hit one side rail as the side thrust shifts the spring to the side, thereby keeping the pleats on both sides of the spring away from the side rails.
