Description

TECHNICAL FIELD

[0001] The present application relates to the field of dismounting tools, in particular to a dismounting tool for a driving wheel of an electric motor. BACKGROUND

[0002] The driving wheel of a rotating table, a stacker and other equipment in an assembly workshop is generally driven by a motor through a sleeve expansion connection with the axle of the driving wheel. The driving wheel is a consumable part and needs to be replaced regularly. However, the sleeve expansion is tightly connected with the axle of the driving wheel, and the weight of the motor and the driving wheel is relatively large, which makes it difficult to dismount and repair the driving wheel on the motor. In the prior art, the driving wheel on the motor is usually dismounted by a hammering method or a hydraulic jack lifting method. In the hammering method, it is not easy to find a suitable knocking point due to the existence of an obstruction between the motor and the driving wheel, and in order to solve the problem of uneven force, the knocking point needs to be changed constantly, which has the risk of workers being injured. In the hydraulic jack lifting method, two hydraulic jacks are needed to lift simultaneously, and when the two hydraulic jacks are lifting, it is impossible to ensure that the force on both sides of the motor is uniform. Uneven force will increase the difficulty of dismounting the driving wheel, and it is easy to damage the motor and the output shaft, which increases the difficulty of repair. In addition, due to the limited stroke of the hydraulic jack, when the hydraulic jack reaches the stroke, a lifting block needs to be used for lifting, which is time-consuming and laborious, and there is also the risk of the lifting block falling, causing a safety hazard.
