The WRV-E series RV reducers feature:
1. Built-in angular contact ball bearings that support external loads, provide high bending rigidity and allow for high permissible bending moments, improving reliability.
2. Two-stage reduction design:
The slower orbital speed of the wobble gear results in lower vibration. The direct connection between the motor and input gear reduces inertia.
3. Planet carrier support structure:
High torsional rigidity, low vibration, and strong shock resistance.
4. Roller bearing contacts:
Low starting torque, low wear, long service life, and tight arcmin gear backlash.
5. Wobble gear and spline gear design:
Tight gear backlash and strong shock resistance.
Simultaneous meshing of multiple wobble and spline gear teeth effectively resists shock loads.
