High Precision Cycloidal Gear Reducer Robot Use RV Reducer
The eccentric rolling-mechanism gearheads known as cycloidal reducers are a type of servo gearing that has an input shaft that drives a bearing assembly. This in turn drives a cycloidal disc (sometimes called a cam) that connects to an output shaft. The cam has lobes or teeth that engage with a cam follower — typically with pin or needle bearings. The eccentric cam rotation induces rotation of an output shaft at a lower speed and higher torque than the input.
Because of the pin-and-gear structure, cycloidal gearing maintains continuous and distributed power-transmission contact for higher shock resistance than traditional reducers. In fact, some variations can withstand transitory exposure to quadruple their rated torque. High torque density makes for ratios to 185:1 in reasonable gearbox footprints.

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.
