Abstract: A planetary gear system with a sun gear, a ring gear co-axial with the sun gear, at least one planetary gear meshing with both the sun gear and the ring gear, and a planetary gear carrier which rotationally supports the at least one planetary gear. A torque clutch is supported by and connected directly between two of the sun gear, the ring gear, the at least one planetary gear and the planetary gear carrier. The torque clutch prevents relative rotation when an acting torque is below a predetermined torque value and allows relative rotation when the acting torque is above the predetermined torque value. A torque threshold adjustment mechanism is provided for adjusting the predetermined value of the torque at which the torque clutch slips.

Abstract: A drill has a housing, a motor mounted in the housing having a drive spindle, an output spindle rotationally driven by the drive spindle via a torque clutch. The torque clutch slips when the torque across the torque clutch exceeds a predetermined value. The predetermined value of the torque at which the torque clutch starts to slip is adjustable via a torque threshold adjustment mechanism. A sleeve is rotatably mounted on the output spindle. The drive spindle drives the sleeve via a gear system at a same rate and direction as the output spindle so that there is no relative rotation between the sleeve and output spindle when the torque clutch is not slipping and at a different rate and/or direction so that there is relative rotation between the sleeve and output spindle when the torque clutch is slipping.
