Technical Field

The invention belongs to the field of clutch structures, and particularly relates to a clutch assembly and a control box.

Background

Gear drive is widely applied to the field of mechanical drive due to the stability of the gear drive. The gear set is connected with the motor and the output shaft and used for changing the torque of the motor into the torque of the output shaft. In practice, there is a need to add a torque input means to the output shaft, such as manually driving the output shaft to rotate. So as to replace the motor drive with the manual drive in case of motor failure or field emergency operation or maintenance. At the moment, because the output shaft and the motor are meshed and connected through the gear set, the rotation of the output shaft can drive the reverse rotation of the gear set. Therefore, there is a need for an improved gear set such that the rotation of the output shaft is not transmitted to the motor. Namely, the unidirectional transmission between the gear set and the output shaft is realized.
