Cycloidal Planetary Gearbox Speed Reducer , Motor Gear Reducer High Torque With Backlash < 1 Arc
The Cycloidal Gear reducer is a planetary reducer. Generally used at joints of large load - bearing robots. The main advantage is the ability to provide high torque. In large four - axis industrial robots, large six - axis robots are used in large numbers. Including ABB, KUKA, FUNC and YASKAWA also use RV reducers made in Japan, and the representative company is Nabtesco, Japan. Zhenkang has also successfully developed the Chinese RV gearbox.
For 20 years, Zhenkang has been focusing on the development and production of the core components of precision robots, precision motors and precision reducers, from the beginning of the printing motor, to the later wire feeders and automated welding trolleys, to the current RV gearbox. In 2010, it developed the RV reduction gear for industrial robot transmission core components and series AC servo motors, which have been put into mass production.
Zhenkang's 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 reducers. Nantong Zhenkang has patents for inventions on the core technology of RV reducers. Independently developed the cycloidal wheel shaping technology, using the world's most advanced ThinkCore modification method, solved the RV gearbox'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.
