Abstract
The power nut runner comprises two consecutive planetary reduction gearings (12) and a torque limiting release clutch (13) positioned between a common ring gear (25) of the reduction gearings and the tool housing (11). The ring gear is tubular in shape and has an outer annular shoulder (41) at its one end carrying cam teeth for cooperation with a spring biased thrust element (45) via balls (43) and cam surfaces. The thrust element encircles the ring gear and is rotationally locked relative to the housing via a ball spline connection. The ring gear is provided with a rotation detector, a signal producing device located on the outside of the housing and an activation member which is movably supported in a radial opening in the housing and arranged to transfer an activation movement from the rotation detector to the signal production device upon release of the clutch.
