Reduction gearing for electric motor or IC engine - uses radial and axial forces within gearing mechanism to reduce bearing and friction forces for input shaft

摘要

The reduction gearing has the individual cogs arranged to obtain axial and radial counter-bearing forces within the gearing mechanism, so that the bearing and friction forces for the input drive shaft or rotor are reduced. Pref. the gearing uses a relatively small dia. worm shaft (11) with two opposing thread sections cooperating with respective cogs (2,5), with a further cog (4) being adjustable to compensate mfg. tolerances. ADVANTAGE - Reduced vibration and noise at high input revs.
