On December 28, Greatoo（002031）announced that the company’s RV reducers won the patents for utility right certificate awarded by State Intellectual Property Office. Besides, the company was applying for patents for invention for “the spline eccentric shaft of V reducers” and “a type of RV reducers of robots”. The achievements above showed that the company has made new breakthroughs in the core components of robots.

RV reducers are one of the three core components of industrial robots. Reducers in domestic market are mainly imported from foreign countries. Because RV reducers have complex structure, it’s difficult to process RV reducers. Only enterprises with years’ of experience in precision processing can master the technology of producing RV reducers. The design and manufacturing of RV reducers require the technology of heat treatment of materials, micro programming of parts and precision packaging. It takes a long time to master all these technologies because there is a high technical barrier.

RV reducers in domestic market are mainly imported from foreign countries. Ordinary reducers have a complex structure and large size, so it’s difficult to process them and many problems need to be considered in design. The development of domestic robot and equipment industries is seriously limited by the shortcomings of ordinary RV reducers like high costs, huge frictions and intervals among parts, poor transmission performance, low transmission efficiency and short service life.

Invented in 1986, RV reducers have become the reliable and indispensable core components of industrial robots to guarantee the precision operation of robots. Using epicyclic transmission principles and cycloidal mesh, RV reducers feature compact structure, a small size, low weight, a large transmission ratio, high carrying capacity and applicability and security, which are widely used in many industries and reduction gears like industrial robots, automatic packaging and precision medical apparatus and instruments.

After years’ investment and researches, Greatoo has gradually mastered the core technology of RV reducers and continued to upgraded its technology. The company has successfully invented a new type of RV reducers with features like low friction consumption, calorific value and costs and high delivery efficiency and reliability and long service life. The patents will strengthen the company’s intellectual property base of intelligent equipment and support the company’s think tank.
