Rv-E Series Rv Robot Reducer Reduction Gearbox Cycloidal Gear Box Drive Transmission Planetary Gearbox
The E series of RV reducer is a kind of reduction gearbox that centers with the flat specially designed for accurate motion control. This series of speed reducers are featured of a compact body, lightweight, and high rigidity which is strong enough to be against overloading situations. Besides, the advantages of free backlash, micro rotating vibration and low inertia guarantee rapid acceleration, ultra-precise positioning, and smooth movement. The precision gear RV series is an ideal speed reducer especially 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 RV-E reducer is also a kind of standard inline gearbox that provides high performance in an extremely compact and high rigid component configuration. The higher reliability and cost-effectiveness of RV-E robot gearbox thanks to the built-in angular ball bearings to support the external load. The rolling contact components ensure the RV-E gearbox high efficiency and long service life. Furthermore, a 2-stage reduction designed structure reduces the vibration and inertia greatly and at the same time increase the ratios. Besides, Belt/pulley configuration is also available for RV-E reducer.
The RV E reducer is featured with high quality and high precision together with a 2-stage cycloidal design that contributes to high torque, big ratio and shock-resistant capability. RV-E reducer adopts rolling contact components to reduce abrasion and extend the service life. Besides, the specially designed pin and cycloidal gear mechanism reduce the backlash and at the same time provide higher impact resistance than traditional speed reducers. And the RV E cycloidal reducer integrates big internal angular support bearings which offer high moment capacity without the need for an external support device. The perfect gear structure design and powerful roller bearings support of the shaft ensure life-long service time and allow instant peak loads up to 5 times of the nominated torque. (e.g. for emergency stops)
