Product Specification

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.

Structure principle of Cycloidal Gearbox Reducer

• Input shaft/planetary gear

Form the'1st stage planetary gear reduction, realizing different gear reduction ratio through the changing of the gear.

• Pin shell/pin/cycloid gear

Form the 2nd stage gear reduction, achieving high rigidity and high accuracy through the cycloid meshing rate higher than 80% and the nearly zero. - backlash quality fit.

• Crank shaft/output shaft

Realizing the transmmision and output of the torque by connection the 1st and 2nd stage gear reduction mechanism.

• Support bearing

Provides extremely high bending moments and load bearing capacity.

Warranty service of Cycloidal Gearbox Reducer

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

* Please refer to the installation drawing for the actual mounting
