Problems solved by technology
Like this, there will be defects in two aspects. First, because the motion of the operating mechanism of the switchgear is transmitted to the motor through the reduction mechanism, it will cause the wear and tear of the reduction mechanism and the motor, which will greatly shorten the service life of the reduction mechanism and the motor. and may cause malfunction
Secondly, due to manual operation, the movement of the operating mechanism of the switchgear will be transmitted to the motor, so much greater force is required to move the operating mechanism than when operating the operating mechanism alone, so that the operator is particularly laborious to operate, making The operation of the operating mechanism of the switchgear becomes particularly difficult

Embodiment Construction
[0019] The following description of preferred embodiments is exemplary only and in no way restricts the invention and its application or usage.
[0020] A preferred embodiment of the clutch device according to the invention will first be described in general.
[0021] According to another preferred embodiment of the present invention, two through holes symmetrical to the rotation axis of the clutch gear are provided on the peripheral wall of the flange part of the clutch gear. By arranging symmetrical through holes, power can be evenly transmitted between the clutch gear and the transmission shaft in the engaged state, that is, the force on the two can be uniform, thereby reducing excessive local stress and prolonging the service life of the clutch gear and transmission shaft.
[0022] In yet another preferred embodiment of the present invention, grooves corresponding to the through holes are provided on the peripheral wall of the transmission shaft. By providing grooves on t...

The invention relates to a clutch device, comprising: a transmission shaft, on which a transmission component fixedly connected with the transmission shaft is arranged; a clutch gear, which is rotatably sleeved on the transmission shaft, and includes a gear part and a flange part. A through hole is provided on the peripheral wall of the flange part; an engaging separation part is provided in the through hole; a stop sleeve is slidably fitted on the outer peripheral wall of the flange part of the clutch gear, and the stop sleeve has a small diameter part and a large diameter part, the inner diameter of the large diameter part is larger than the outer diameter of the flange part of the clutch gear; and the clutch operating mechanism, which is operatively connected with the limit sleeve. It also relates to a reduction mechanism including the above-mentioned clutch device. By applying the deceleration mechanism including the clutch device according to the present invention to a switchgear such as a dual power switch, the clutch device can be in a disengaged state when the switchgear is manually operated, thereby reducing the user's manipulation force and avoiding Motor wear.
Description
technical field [0001] The present invention relates to a clutch device, in particular to a clutch device for operating a motor reduction mechanism of a switchgear, such as a dual-power automatic transfer switch. In addition, the present invention also relates to a reduction mechanism including the clutch device described above. Background technique [0002] In the prior art, a switching device such as a dual power transfer switch is usually driven by a motor, so as to realize switching or switching of the switching device. Since the motor usually has a high-speed output, and the switching operation of the switchgear needs to be completed at a low speed, it is necessary to set a deceleration mechanism between the output part of the motor and the operating mechanism of the switchgear, so as to convert the high-speed output of the motor into a function capable of manipulating the switchgear. Low speed movement of the operating mechanism. [0003] When the operating mechanism...
