Product Description

28mm Miniature Precision Planetary Gearbox Speed Reducer
 

Product Description

A planetary gearbox is a gearbox with the same center of rotation for both input and output. This means that the center of the input gear rotates around the center of the output gear, and the input shaft and output shaft are aligned. The structure of the planetary gearbox reduces the transmission speed ratio while increasing the motor torque proportionally.
Planetary gearboxes are used in various occasions where efficiency and high reduction ratios are needed in a small space. With high precision and high torque volume ratio, they are very suitable for the following applications: increasing torque, reducing speed, accurately positioning and controlling reproducible machinery. In order to ensure that the selected planetary gearbox is most suitable for your application at hand, it is important to consider specifications including torque, backlash and ratio when selecting a planetary gearbox.
 

FEATURES:

• High efficiency: The single-stage efficiency can reach over 95%
• High precision: generally less than 10 arc minutes, even up to 5 arc minutes
• Strong bearing capacity: radial load can reach over 20000N
• Compact structure and small volume: usually with an outer diameter size of tens to hundreds of millimeters
• Low noise and minimal vibration: The noise level during operation is usually below 65dB
• Wide speed ratio range: single-stage speed ratios range from 3-10, and multi-stage combinations can reach thousands
• High reliability and long lifespan: the service life can reach 20000 hours
