Tool for dismounting fastener on motor output shaft and dismounting method

Abstract

The invention provides a tool for dismounting fastener on a motor output shaft and a dismounting method and belongs to the field of a dismounting tool; the tool comprises a baseboard and a top plate being parallel to each other at interval, the baseboard and the top plate are connected through a stand column. The method comprises the following steps: placing the baseboard between a motor and a turntable through an opening formed in the baseboard of the tool; placing a jack between an output shaft of a motor and the top plate of the tool; operating the jack for lifting a piston rod, and dismounting the turntable with fan blades from the output shaft of the motor through the top plate and the baseboard. The turntable with fan blades can be dismounted by the tool and the method, and a bearing or other devices connected to the motor can also be dismounted by adopting the tool; the same effect is achieved, and the tool and the method are widely adopted for popularization and application.

Description

technical field [0001] The invention relates to the field of dismounting devices, in particular to a tool for dismounting a fastener on an output shaft of a motor and a dismounting method. Background technique [0002] The motor is a commonly used device, and other fasteners such as bearings or turntables are often sleeved on the output shaft of the motor, and the fasteners and the output shaft of the motor have an interference fit and are connected by a key. Removing the fasteners on the output shaft of the motor is a relatively laborious work, because the two are very closely matched, it is difficult to remove, and tools are often used to remove them. [0003] One of the commonly used removal tools in the prior art is a puller. During use, the claws of the puller are stuck on the edge of the bearing or the turntable, and the center of the puller is pressed against the shaft end of the output shaft of the motor. Drive the jaws to move, thereby removing the fastener from th...

Problems solved by technology

[0004] Although this removal tool can remove the fastener, it is very laborious

And its limitations are relatively large. When the edge of the fastener on the output shaft of the motor is fixed with multiple fan blades, using a puller to disassemble the turntable will inevitably damage the fan blades, so its practicability is low and the practical range is narrow.
