Robot special RV reducer: installed with radial thrust ball bearings, so it can support external load, torque rigidity, allow torque is large, can reduce the number of components required, easy installation. The revolution speed of WRV gears is slower and vibration is reduced, which can reduce the motor structure (input gear) and inertia.
WRV-E series Manipulator 2KW high output torque density helical gear reducer Features:
1, the main bearing built-in mechanism
Improved reliability; Total cost reduction; Installed with radial thrust ball bearings, so it can support external load, torque rigidity, large allowable torque, can reduce the number of components required, easy installation.
2, 2 speed reduction mechanism
The vibration is small, the revolution speed of WRV gear is slow, and the vibration is reduced, which can reduce the straight junction part of the motor (input gear) and reduce the inertia.
3, double column support mechanism
Large torsional rigidity, small vibration, strong impact resistance; The crank shaft in the reducer is supported by two columns.
4. Rolling contact mechanism
Excellent starting power, small wear, long life; Small backlash (1arc.min); Use rolling bearings.
5, pin gear mechanism
Small backlash (1arc.min); Strong impact resistance; WRV gears and pins have more simultaneous bites.
