Genius Robotics Zhenkang currently has strategic cooperation with domestic robot companies Anhui Eft, Nanjing Estun, Guangzhou CNC, Qianjiang Robot, etc. The sales volume has a large market share in China's cycloid RV gear reducer, and it has established a domestic position. The quality is comparable to Japan's Teijin RV reducer.

Genius Robotics Zhenkang precision cycloid RV gear reducer has superior performance in a very compact and high-precision component configuration. The components include rolling contact components to achieve higher efficiency and longer service life. The integrated angular bearing supports external loads, and the two-stage reduction design improves the reduction ratio while reducing vibration and inertia.

The RV-E model is also available in belt and pulley designs.

The precision cycloid RV gear reducer has large transmission ratio, high transmission efficiency, high motion accuracy, small backlash, low vibration, high rigidity, and high reliability. It is the "queen" reducer of industrial robots, and the leg of an industrial robot , Waist and elbows need 4 to 6 RV reducers, the cost of the reducer accounts for 40% to 60%.

The structure of precision cycloid RV gear reducer

The structure of the precision cycloid RV gear reducer is mainly divided into gear shafts, planet wheels, rotating arms, cycloids, pin wheels, rigid discs and output discs, etc.:

　　1. Gear shaft: The gear shaft is used to transmit input power and meshes with the involute planetary gear;

　　2. Planetary gear: it is fixedly connected with the rotating arm (crankshaft), and the 3 planetary gears are evenly distributed on a circle, acting as a power splitter, that is, the input power is divided into two ways and transmitted to the cycloid pinwheel planetary mechanism;

　　3. Rotating arm (crank shaft) H: Rotating arm is the axis of rotation of the cycloid. One end of it is connected with the planetary wheel, and the other end is connected with the supporting disc. It can drive the cycloid to produce revolution, and it also supports the cycloid to produce rotation;

4. Cycloidal gear (RV gear): In order to achieve the balance of radial force in the transmission mechanism, generally two identical cycloidal gears should be used, respectively installed on the crankshaft, and the eccentric position of the two cycloidal gears 180° to each other;

　　5. Needle wheel: The needle wheel is fixedly connected with the frame to form the needle wheel housing;

　　6. ​​Rigid disc and output disc: The output disc is a component that connects the RV-type transmission mechanism with the external driven machine. The output disc and the rigid disc are connected as a whole to output motion or power. The bearing holes of the three rotating arms are evenly distributed on the rigid disk, and the output end of the rotating arm is mounted on the rigid disk by means of bearings.

The bearing of the precision cycloid RV gear reducer is its weak link. It is easy to break through the bearing force limit when subjected to force and cause abnormal wear or rupture of the bearing. This problem is more prominent during high-speed operation, so the rated torque of the cycloid RV gear reducer decreases significantly with the input speed.
