RV-M Series Robot Gearbox

Overview of RV-M Series Robotic Reducer

  • Less than 1 arc-min backlash
  • The gearbox is easy to connect with servo motor.
  • With compact structure and high torsional rigidity.
  • Integrated angular bearings for large thrust & overhung moment capacity.
  • High ratio availability (up to 258:1) without increasing gearbox size.
  • High torque capacity is up to 5 times of the rated torque (Emergency Stop).
  • Compact structure and small volume for space saving.


Description of RV-M Series Precision Speed Reducer

The TQG RVM reducer is a kind of solid reduction gearbox that centers with the flat specially designed for accurate motion control. This series RVM is designed with flange input based on the RV-E series reducer. All the specifications are the same with that of RV-E series. The total length in the axial direction has been reduced by up to 15% compared with the previous series. This series speed reducers are featured of compact body, light weight and high rigidity which is strong enough to be against overloading situations. Besides, advantages of free backlash, micro rotating vibration and low inertia guarantee the rapid acceleration, ultra precise positioning and smooth movement. The precision gear RVM series is an ideal speed reducer specially for precision mechanical control in the fields of machine tools, factory robots, assembly equipment, conveying machines and other related fields that need precise positioning, high rigidity and shock-load capacity.


The TQG RV-M reducer is a kind of standard inline gearbox which provides high performance in an extremely compact and high rigid component configuration. The higher reliability and cost effective of RV-M robot gearbox thanks to the built-in angular ball bearings to support the external load. The rolling contact components ensure RV-M gearbox the high efficiency and long service life. Furthermore, 2-stage reduction designed structure reduce the vibration and inertia greatly and at the same time increase the ratios. Besides, Belt/pulley configuration is also available for RV-M reducer.
