Precision Reducer RVis a two-stage decelerating speed reducer with a spur gear reduction gear at the front stage of the "eccentric differential type" speed reducer using a pinion gear on the internal tooth and a system gear as the internal tooth .

One point difference using the trochoidal tooth form In the case of the inscribed planetary gear mechanism using two or three axle speed reduced speed gears for eccentric rotational motion input mechanism, the conventional "eccentric differential method" deceleration It is greatly different from the aircraft and has become a feature on the mechanism

Structure and features

1. One piece difference inscribed planetary mechanism by trochoid gear

① Compact · Input / output axis concentric

② It can greatly decelerate at the 2nd deceleration part

③ The tooth is strong, there is no breakage problem, the number of simultaneous engagement is many and it is strong against impact

2. 2-stage speed reduction mechanism

(1) In the vibration characteristics, the resonance rotation number can be made much higher by the first reduction section, and it is possible to eliminate the vibration at the low speed, which is particularly problematic.

② The speed reducer is small

③ By changing the reduction ratio of the first reduction gear, a wide reduction gear ratio can be obtained.

3. Dual-supported support mechanism

① High twist

② Because the rigidity is high, the torque transmission part does not come in contact and can withstand the overload

Four. Rolling bearing structure

① High efficiency because rolling contact is excluded except pin support of pin gear

② The friction caused by the sliding contact is suppressed as much as possible, and the increase of frictional damage is prevented.
