ABSTRACT:
A one-way clutch generally comprising a driving member, a carrier ring and a driven member. The carrier ring is disposed concentrically with the driving and driven members and disposed therebetween. The carrier ring includes at least one cut-out within which a key is disposed for pivotal rotation relative to the carrier ring. Each of the driving and driven members further include a plurality of circumferentially spaced key engaging notches. When the driving member rotates in a first rotational direction one end of the key engages with one of the key engaging notches within the driving member. Subsequently, a second outer end portion of the same key engages with one of the key engaging notches in the driven member. This allows the driving member to drive the driven member through the single engaged key. When the driving member is rotated in the opposite rotational direction, the driving member urges the engaged key out of engagement with the key engaging notch with which it was previously engaged and thereafter moves freely in an over-running running condition without engaging the key. The apparatus is particularly well adapted and well adapted for high rpm applications. In a preferred embodiment the arm portions of the key are offset from a longitudinal center of the main body portion to enable centrifugal force to urge one end of the key outwardly into locking engagement with one or more driven members. In this embodiment the carrier ring acts as the driving member.
