WRV-E Series RV Gear Reducers-Fubao Mechanical

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.
