Product Description
Precision planetary reducers are key core components in modern mechanical transmission systems. They combine advanced design concepts and sophisticated manufacturing processes to provide accurate, efficient and reliable power transmission solutions for equipment operation in many industries.
Precision planetary reducers use the principle of planetary gear transmission. The sun gear is located in the center, and multiple planetary gears are evenly surrounded and meshed with the sun gear. These planetary gears interact with the outer gear ring at the same time, and the planet carrier integrates the movement of the planetary gears for output. This unique structural design is the basis of its excellent performance.

Product Display
High precision
- Precise transmission: The combined design and manufacturing process of the internal gears are excellent, which makes the transmission error extremely small and can achieve precise positioning and control. For example, in the feed system of CNC machine tools, the precision planetary reducer can ensure that the tool moves accurately to the specified position and improve the processing accuracy.
- Low backlash: The single-stage backlash can be within 3 arc minutes, and the double-stage backlash can be within 5 arc minutes. The small backlash means that the reducer has a small idle stroke when switching between forward and reverse directions, which ensures the accuracy and continuity of the movement.
High efficiency
- Low energy loss: The structural design and reasonable meshing method of the planetary gear reduce energy loss during the transmission process. The single-stage deceleration efficiency is usually above 95%, and the double-stage deceleration efficiency can also reach above 92%, which can significantly reduce energy consumption and improve the economy of the system in long-term operation of equipment.
- High power density: Under the same volume or weight, it can transmit greater power to meet the equipment's demand for high power output.
