Description

Technical Field

[0001] This utility model relates to the field of planetary gear reducer technology, and in particular to a dual-mode planetary gear reducer that can be used for both power on and off. Background Technology

[0002] A planetary reducer that can operate with both power on and off requires the addition of a manual input terminal. When power is off, power can be input through the manual input terminal to control the status of the equipment. The manual input terminal uses a bevel gear set to connect to the input shaft. In the past, the bevel gears were directly fixed to the input shaft with screws, resulting in poor assembly accuracy. In addition, during operation, due to the influence of working environment factors, the stability of the planetary reduction assembly is insufficient when encountering large impacts, and the planetary gear pins are also at risk of backing back. Therefore, improvements are still needed. Utility Model Content
