RV Gear Reducer
Standard RV Reducer
Standard RV (Rotary Vector) Reducer is a reduction device specially designed for precision machinery. It adopts a two-stage enclosed differential gear mechanism composed of a cycloidal pinwheel and a planetary gear set. The reducer itself is an open-type structure; therefore, during application, flange sealing and filling with dedicated RV grease are required.
In the field of industrial robots, for robotic arms with an end payload of 20 kg or less, RV reducers are mainly applied to the base and high-load joints of the robot (typically joints 1 to 4). For robotic arms with an end payload exceeding 20 kg, all six joints (degrees of freedom) are equipped with RV reducers. The RV reducer is a core transmission component that ensures the positioning accuracy of robotic arms.
According to structural characteristics, standard RV reducers can be classified into:Standard E Series: solid-shaft structure,Standard C Series: hollow-shaft structure
Brief Usage Instructions
Both the Standard E Series and Standard C Series are open structures without flange sealing. After purchase, customers are required to perform flange sealing and inject dedicated RV lubricating grease. In addition, the solid input shaft supplied from the factory must be re-machined (shaft boring and keyway machining) according to the customer’s motor input shaft specifications.
Our company can provide custom secondary machining services for the input shaft based on the drawings supplied by the customer.

Flange RV Reducer
Flange-Integrated RV (Rotary Vector) Reducer is a reduction device specifically designed for precision machinery. It adopts a two-stage enclosed differential gear mechanism composed of a cycloidal pinwheel and a planetary gear set. The reducer is factory-assembled with an integrated flange-sealed structure and pre-filled with dedicated RV lubricating grease, allowing customers to use it directly with a servo motor out of the box.
In the field of industrial robots, for robotic arms with an end payload of 20 kg or less, RV reducers are mainly applied to the base and high-load joints of the robot (typically joints 1 to 4). For robotic arms with an end payload exceeding 20 kg, all six joints (degrees of freedom) are equipped with RV reducers. The RV reducer is a core transmission component that ensures the positioning accuracy of robotic arms.
The flange-integrated RV reducer is a customized model developed by adding flange sealing to the standard RV reducer. According to the same classification characteristics as standard RV reducers, flange-integrated RV reducers can be divided into:Flange-Integrated E Series: solid-shaft structure,Flange-Integrated C Series: hollow-shaft structure
