High Precision Industrial RV Reducer For Industrial Robotics And
Automation
RV reducer are used for the three joints of the waist and elbow of the leg of the
robot with large torque, and the industrial robot with large load
uses RV for one, two and three axes. Compared with the harmonic
reducer, the key to the RV reducer lies in the processing
technology and assembly process. RV reducer has higher fatigue
strength, stiffness and life.
Key Features
- Zero Backlash: One of the key features of RV reducers is their
zero-backlash operation, ensuring accurate positioning and smooth
motion transmission.
- High Precision: RV reducers provide high precision and
repeatability, making them suitable for applications that require
precise motion control.
- High Torque Capacity: Despite their compact size, RV reducers can
handle high torque loads, making them suitable for demanding
applications.
- Low Noise and Vibration: They operate with low noise and vibration
levels, ensuring smooth and quiet operation, which is essential in
many applications, including robotics and automation.

FAQ
What are the benefits of a cycloidal drive?
Cycloidal gearboxes offer several advantages, including high
reduction ratios, compact design, exceptional load-bearing
capacity, minimal backlash, and excellent shock resistance. These
features make them ideal for applications requiring precise motion
control and reliability under heavy loads.
Do cycloidal RV reducer gears have backlash?
The advantages of cycloidal gears over planetary gears:
Virtually backlash-free for the whole lifetime. Higher rigidity.
More compact design.
How does a cycloid RV reducer work?
The input shaft is mounted eccentrically to a rolling-element
bearing (typically a cylindrical roller bearing), causing the
cycloidal disc to wobble in a circle. The cycloidal disc will
independently rotate around the bearing as it is pushed against the
ring gear.
What is RV speed reducer?
RV reducer is a high-precision control reducer with a cycloidal pin
wheel reduction structure. Due to the large number of gears engaged
at the same time, the reducer has the characteristics of small
size, lightweight, high rigidity, and overload resistance.
