Two Stage Cycloidal Gearbox Reducer With Tooth Modifications, Same As Nabtesco Rv
The Cycloidal Gear reducer is a new type of transmission developed on the basis of cycloidal pinwheel drives, it 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.
We has successfully developed Cycloidal Gear reducer for robots under 300 kg, with a total of 17 products.
E series RV-20E, RV-40E, RV-80E, RV-110E, RV-160E, RV-320E, RV-450E
C series RV-10C, RV-27C, RV-50C, RV-100C, RV-120C, RV-200C, RV-320C, RV-320CA.
And RD series RD-20E, RD-50C.
They are widely used in high - end intelligent equipment industry such as industrial robots, external shafts, precision machine tools, radars, and medical devices.
Cycloidal Gearbox Reducer advantages
Our technological advancement lies in the key technologies of design principles, structural design, material optimization, processing and assembly processes, heat treatment, process inspection and quality control, and comprehensive performance testing of high - precision RV gearboxes. We has patents for inventions on the core technology of RV gearboxes. Independently developed the cycloidal wheel shaping technology, using the world's most advanced ThinkCore modification method, solved the RV reducer's shape modification problem for the first time in China. This technology has been made into a design software module, breaking the foreign special practice design software. Blockade. It has taken the lead in mass production of robot RV reducers in China.
Based on the comprehensive import performance of our RV reducer, its market competitiveness lies in reasonable prices. With higher cost performance, the same quality and installation interchangeability, it has won widespread recognition in the market. Since 2012, more than 30,000 RV gearboxes have been put on the market, and user feedback has been good. At the same time, in 2018, our RV gearbox has a production capacity of 30,000 units, and has been favored by more and more robot manufacturers with its short delivery time, high cost performance and stable quality. On December 18, 2016, the 25,000 square meter factory building of Welding Robot Industrial Park has been basically completed. After the project is fully put into operation, the park's development goal is to produce 200,000 RV gearboxes and 10,000 welding robots.
