<p>A one-way clutch (1) is disclosed. The clutch includes a sleeve (3) securable to a shaft (2) and a coaxial housing (4) having an inner right circular cylindrical gripping surface rotatable relative to the sleeve. It also includes at least one gripping shoe (6) between the sleeve and the housing with a gripping surface coaxial with the housing. The gripping shoe effective gripping surface circumference is increasable and decreasable through relative rotation of the sleeve and the housing. The clutch includes means to control (5) the increase and decrease of the gripping shoe gripping surface circumference such that when the circumference is increased the gripping surface of the gripping shoe grips the gripping surface of the housing and when the circumference is decreased the gripping shoe is released from the housing. The invention also extends to a clutch in which the gripping shoe grips the sleeve upon decrease of the gripping shoe gripping surface circumference.</p> |
