High-precision 2-stage cycloid high-torque RV gear reducer

The RV-320E series of RV reducer is a kind of reduction gearbox that centers with the flat specially designed for accurate motion control. 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 RV 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 RV-320E reducer is also 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-E robot gearbox thanks to the built-in angular ball bearings to support the external load. The rolling contact components ensure RV-E 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-E reducer.

The RV-320E 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 special 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 a big internal angular support bearings which offer high moment capacity without the need of 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)

• High torsional rigidityand extremely compact body.
• 1 arc-min of low backlash.
• Flexible design of inline component for space saving
• Large thrust & overhung moment capacitythanks to the integrated angular bearings.
• High Ratios are in available (up to 185:1) without increasing the sizeof gearbox.
• High torque capacity is up to 5 times of therated torque (E-Stop)

Leading technology

1. High stiffness configuration technology
The robot body with a rated load of six kilograms uses four RV reducers (50C, 40E, 20E, 10C) and two harmonic reducers (SHG20, SHG25), and all six reducers are designed with high rigidity and custom design.

2. Low noise technology
Using the world's leading input shaft refining technology, the noise of the reducer is lower than that of the imported products, thus obtaining the mute effect of the whole machine.

3. Reducer and motor integration technology
RV reducer and servo motor share the same axis, reduce assembly error, improve joint accuracy and extend working life.

4. Welding system embedded technology
The robotic welding hardware system (wire spool, wire feeder, anti - collision, welding torch, cable) and the robot body cleverly integrate the in-line design to obtain the welding effect that is unimaginable for ordinary robots.

5. Metal color technology
The first "naked" robot with cast aluminum parts, no paint, and anti - oxidation all year round, is innovative in green manufacturing.

6. Drive and control integrated technology
Greatly reduce the volume of control cabinet, any part of the robot can “sense the external force” and stop when touched, effectively improving the safety of the robot.
7. Perfect welding technology
Provide technical support for various complex welding processes with long-term accumulated welding experience. For example, a thin plate of stainless steel or aluminum plate with a thickness of less than 1.5 mm is welded.

    Shanghai Genius Industrial Co.,Ltd is the branch of Nantong Zhenkang Machinery Co.,Ltd, which founded in 1993, with 30 years of experience in the production of CO2 welding wire feeder, nowadays we occupy 70% Chinese market and 50% global market for wire feeder, long partners of PANASONIC and OTC Daihen.

    In 2009, we started R&D high precison RV reduction gearbox, this is core part of industrial robots, through 4 years research and development, in 2013, our high precision RV reduction gearbox start bulk production. Nowadays we become China biggest RV reduction gearbox manufacturer, realized robotic automatically produce RV reduction gearbox, also we are supplier of world famous company ABB, FNUC, YASKAWA for gearbox.

    As had advantage of wire feeder and RV gear reducer, with accumulated years of welding experience, we decide to R&D welding robot, After more than one year testing, our welding robot developed successfully in 2016, much earlier than other robot manufacturers in China, now our robot already in market for 5 years, still work well, got good comments from customers.
