a clutch structure

Abstract

The invention discloses a clutch structure. The clutch structure comprises a reset spring, a clutch shaft, a fixing rotating shaft and a push rod, wherein a groove matched with a motor output shaft is formed in the end surface of the lower end of the clutch shaft, and the clutch shaft is sheathed on the motor output shaft through the groove; the reset spring is sheathed on the motor output shaft, the end surface of the lower end of the reset spring pushes against the root of the motor output shaft, and the end surface of the upper end of the reset spring pushes against the end surface where the groove of the clutch shaft is located; the lower end of the fixing rotating shaft is mutually meshed with the upper end of the clutch shaft, and the upper end of the fixing rotating shaft is fixed on an operation panel and can rotate around the axial direction of the fixing rotating shaft; the lower end of the push rod pushes against the end surface of the upper end of the clutch shaft, and the upper end of the push rod is fixed on an operation panel and can move along the direction parallel to the axial direction of the fixing rotating shaft; when the push rod is pressed down, the clutch shaft is separated from the fixing rotating shaft, the motor output shaft idles; and when the push rod bounces, the clutch shaft is meshed with the fixing rotating shaft, and the rotation of the motor output shaft is transmitted to the fixing rotating shaft. The clutch structure can realize the clutch operation of the fixing rotating shaft and a motor.

Description

Technical field [0001] The invention relates to a clutch structure, in particular to a clutch structure of a motor drive mechanism. Background technique [0002] For most dual power transfer switches driven by a motor, the transmission mechanism of the motor has no clutch function. When manually operated, the motor will rotate with the transmission mechanism, and manual operation requires a lot of force and is very laborious. For high current transfer switches, manual operation is more difficult. At the same time, since the motor will drive the gearbox to rotate together during manual operation, the wear of the motor and the gearbox is accelerated, and the life of the entire system is reduced. [0003] Therefore, it is necessary to switch on the power when the motor is driven, and disconnect the power connection when manually operating, and the connection and separation must be reliable. [0004] One of the existing solutions is to provide a clutch device in the gear box, which is...

AI Technical Summary

Problems solved by technology

[0004] An existing solution is to install a clutch device in the gearbox, which is more complicated, has many parts, and is expensive

Further, the clutch device is far away from the operation interface, an additional transmission mechanism is required to operate the clutch device, the reliability of the operation is low, and the cost is increased.
