ABSTRACT:
A power skinning knife with a drive mechanism that may be easily removed for cleaning and a high efficiency pneumatic motor. The main drive gear is located on the same side of the pinion gear as the drive mechanism cover plate permitting removal of the drive mechanism without removing the drive motor. Other improvements include a replaceable main bearing plate in case of bearing failure damage, a combined drive mechanism cover and barrier plate manufactured of a different material than the remained of the housing to increase wear resistance, hollow drive pins to reduce the oscillating mass and operating vibration, and a spring mounting for the motor to assure accurate alignment of the motor and gearing system after each disassembly of the tool. The pneumatic motor comprises an improved sealing system to increase efficiency, an overlappingly staggered exhaust venting system to decrease operating noise, and a rotor using a slip fitted bearing and anti-slip O-ring design that may be disassembled by hand for cleaning.
