The RV-C hollow shaft reducer is equipped with a central through hole and component configuration to achieve greater design flexibility and space saving. The component contains rolling contact components to achieve high efficiency, long service life and minimal backlash. At the same time, an eccentric second-stage deceleration is designed to increase the reduction ratio selection while reducing vibration and inertia. The reducer is also equipped with a set of large internal angle bearings to achieve greater load capacity and reduce the need for external support equipment-thereby reducing design time and installation costs.

RV-C hollow shaft is also available in right-angle configuration to enhance the ability to save more space.

1. The integrated angular bearing increases the rigidity of the reducer and realizes the ability of the precision reducer to support larger external loads. Therefore, the need for external support equipment is reduced, the number of parts required is reduced, the reliability is increased, and the total cost is reduced.

2. The 100% continuous meshing design of the cycloidal gear and the needle teeth can achieve a larger impact load capacity and a smaller backlash, because the force is evenly distributed to the entire reducer gear.

3. The patented two-stage deceleration mechanism reduces vibration because the two cycloid gears rotate at a lower speed, and the reduced input shaft size reduces the inertia. Various reduction ratios can be obtained by simply changing the combination of spur gears in the first stage.

4. The use of rolling contact parts in the reducer is beneficial to achieve excellent starting efficiency; reduce wear, obtain longer service life and reduce backlash.

RV reducer working principle: the planetary gear reduction mechanism is used as the first-stage reduction, and the cycloid pin-wheel reduction mechanism is added as the second-stage reduction, and the overall mechanism is connected through the rigid disk and the output disk, and the output is finally reduced. Application areas: 6-axis industrial robots 1st, 2nd, 3rd joints and other heavy-duty equipment. Performance characteristics: large reduction ratio, high rigidity, strong impact resistance and strong carrying capacity. Compact structure, reliable use and long life. Main disadvantages: large volume, heavy weight, complicated processing technology, large number of parts

Most of the global market share is occupied by Japanese companies: Nabtesco's RV reducer accounts for about 60%, and Harmonica's harmonic reducer accounts for about 15%.

It is worth mentioning that it took 6-7 years for Nabtesco Corporation in Japan to propose the RV design in the early 1980s to the RV reducer research in 1986, and it took 6-7 years; and our company was the first company in China to produce results.

Genius Robotics Zhenkang also took 6-8 years; it can be seen that there is no shortcut to technology. In other words, the current level of development of domestic RV reducers still stays in Japan in the late 1980s.

ABB, FANUC, Yaskawa, KUKA and other international mainstream robot manufacturers all provide reducers from the above two Japanese companies. However, due to fierce market competition, some manufacturers have begun to test and use Chinese RV reducers.

Genius Robotics Zhenkang had an annual output of more than 80,000 units last year, and it supplied many robot manufacturers, including foreign ABB, KUKA, FANUC, and domestic companies such as Eft and Eston. Among them, Eft purchased 8,000 RV reducers.
