Characteristics of RV series worm gearbox and gear motor

The worm gearbox assembly from worm wheel, worm gear, housing, oil seal, bearings, etc.SDT Transmission is one of the worm gearbox manufacturers, the hollow shaft type worm gear reducer is equipped with a helical gear unit at the input end of the worm gear reducer. The multi-stage gear reducer can achieve a very low output speed. RV series worm gearbox can be a combination of the helical gear stage and the worm gear stage. The single-stage worm gear reducer has higher efficiency. moreover, the gearbox’s vibration is small, the gearbox’s noise is low, and the energy consumption is also low.
