Abstract: The Shaft Spring Cutch is an apparatus, used to drive fasteners, or the like, that is multi-directional, and non-ratcheting, comprised of two drive members, separated and held in an unengaged position by a return spring, that are axially retained within a guide housing.

The teeth of the gearings slide and the sockets rotate relatively to each other and interrupt the torque-transmission if a pre-adjusted torque is exceeded.

Abstract: A right angle indexer includes an internal torque limiter. The indexer includes an input shaft with a cam, and an output shaft. The cam on the input shaft rotates a hub on the output shaft. The hub is rotatable relative to the output shaft. The output shaft has a driven surface, and the hub has a drive surface.

Abstract: A lock washer (24) presses balls (21) and pins (23) against a clutch cam (18) with protrusions (19) formed on its front face. A rear end (25a) of a spring holder (25) abuts on the inner edge of the front face of the lock washer (24) while the half of the front end surface of each pin (23) abuts on the rear face of the outer edge of the lock washer (24). Furthermore, the compression spring (26) also abuts on the lock washer (24) with its outer edge approximately aligned with the outer edge of the lock washer (24). Therefore, if a large load is instantaneously applied to a spindle (11) at the end of screw tightening, the outer edge of the lock washer (24) deforms forward. This in turn causes the balls (21) to ride over the protrusions (19) of the clutch face, thus allowing a slight rotation of the internal gear (10c). This clutch operation lessens the impact that occurs at the end of screw tightening, serving to protect the tool mechanism and to reduce the shock to the operator's hand.
