Abstract

[0002] A split reducer is a specially designed reducer whose main body can be manufactured in multiple independent parts. The main body of the split reducer is composed of multiple independent parts, which allows it to be disassembled when lubrication and maintenance are required. Compared with an integral reducer, the installation, maintenance and replacement of spare parts of a split reducer may be more complicated because multiple parts need to be disassembled and assembled.
[0003] Compared with the existing technology: the existing split-type reducer does not have a planetary gear set structure, which may affect the deceleration effect and torque output. The planetary gear set, with its unique structural characteristics, can achieve a larger reduction ratio without increasing the volume and provide a higher output torque. Without a planetary gear set, the deceleration effect of the reducer may be limited, and the torque output may not reach the expected level. Without a planetary gear set, the transmission accuracy of the reducer may be reduced, and the strength of the parts may also be affected to a certain extent.
