Integrated RV Reduction Gear RV-C, Full Model Repace Nabtesco Reducer
The compact cycloidal pinwheel hollow RV reducer RV-10C allows the wires to pass through the middle.
It is small in size, high in accuracy, large in load and torque, and high in transmission ratio. It can be used for welding rotary tables, industrial robots, and medical equipment, precision CNC machining tool.
The precision cycloid gear reducer RV-10C is also called the cycloidal pinwheel RV reducer RV-10C. Compared with the harmonic reducer, the precision cycloid RV gear reducer has a longer service life and reliability.
Working principle of RV reduction gear
The RV drive is a new type of transmission developed on the basis of cycloidal pinwheel drives, the RV reducer consists of an involute cylindrical gear planetary reduction mechanism and a cycloidal pinion planetary reduction mechanism. The involute planetary gear is integrated with the crankshaft as an input to the cycloidal pinion drive section.The crankshaft drives the cycloidal wheel for eccentric motion.The crank rotates clockwise clockwise for 1 week and the cycloidal wheel moves 1 tooth counterclockwise.The core components of the RV reducer are the pin housing, the crank shaft and the cycloidal wheel.
RV reduction gear application

Warranty service of RV reduction gear
We provide one year quality warranty for our ZKRV series of gear reducers provided that they are used under rated conditions, assembled properly or applied under good lubrications. During this warranty period, refund or free replacement is guaranteed by our company when the performance of the gear reducer is severely downgraded or malfunctioned, however, we will not be responsible for the other costs arisen hereof.
The following situations are exempted from our warranty scope while paid service is available
- The gear reducer is not used based on given conditions
- Foreign objects enter into the gear reducer
- The specification of the lubrication and supporting material used does not meet with given conditions
- Disassemble or reassemble the gear reducer without authorization
RV reduction gear RV-10C -27 installation drawings
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.
