Abstract:
A gear wrench comprising:a drive head having an output shaft;an indexing clutch assembly including a rotor operably coupled to said output shaft, a drive shaft, a freewheeling mechanism interconnecting said rotor and said drive shaft and operable in an engaged mode to provide concurrent rotation of said rotor and said drive shaft in a first direction and a disengaged mode to permit relative rotation therebetween in a second direction, a stator, and an indexing mechanism interconnecting said drive shaft and said stator and operable in a non-actuated mode to permit relative rotation between said drive shaft and said stator in said first direction and an actuated mode to permit limited relative rotation between the drive shaft and the stator in said second direction until said drive shaft reaches a predetermined indexing position at which point said indexing mechanism selectively engages said drive shaft to prevent further relative rotation in said second direction; anda gear assembly including a gear housing having a gear housing slot formed therein, a drive gear supported for rotation in said gear housing and operably coupled to said drive shaft, a socket gear supported for rotation in said gear housing and having a slot formed therein, and an idler gear supported for rotation in said gear housing and operably coupling said drive gear and said socket gear, said socket gear slot being aligned with said gear housing slot when said drive shaft is in said predetermined indexing position.
