Problems solved by technology

Although this heating method exerts less force on the hub and reduces labor intensity during disassembly, it is prone to deformation due to the heating of the hub
After the overhaul is completed, the hub needs to be reinstalled on the shaft. Due to the deformation of the hub, the coupling cannot be well centered, which will affect the force transmission between the shaft and the shaft.

Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] In the present invention, unless otherwise stated, the used orientation words such as "up, down, left, and right" generally refer to up, down, left, and right in the drawings.

[0036] As known to those skilled in the art, couplings are widely used in various fields. The couplings involved in the present invention mainly refer to couplings in large motors, but are not limited thereto.

[0037] see figure 1 with figure 2 , The coupling removal device of the present invention mainly includes: a clamping assembly 10 , a moving assembly 20 , a telescopic assembly 30 and a control system 40 . Wherein, the clamping assembly 10 is used for clamping on the c...

Abstract

The invention discloses a coupler dismounting device which comprises a clamping assembly (10), a moving assembly (20), a telescopic assembly (30) and a control system (40), wherein the clamping assembly is used for being clamped on a coupler; the clamping assembly is arranged on the moving assembly in a mode of being capable of moving horizontally, and the moving assembly ensures that the clamping assembly can move in a vertical direction; the telescopic assembly (30) is fixedly arranged on the moving assembly (20) and used for moving a shaft connected with the coupler; and the control system (40) is used for controlling the movement of the moving assembly and the telescoping of the telescopic assembly. The coupler dismounting device disclosed by the invention can be used for dismounting couplers with greater diameters; and compared with a dismounting process based on a heating method, the coupler dismounting device has the advantages that the hub deformation is reduced, the coupler can be dismounted rapidly and efficiently, the equipment overhaul time is reduced and the overhaul efficiency is improved.

Description

technical field [0001] The invention relates to the field of electromechanical equipment maintenance, in particular to a device for removing a shaft coupling used in a motor. Background technique [0002] As we all know, rotating equipment needs to be overhauled after running for a period of time to restore the operating performance of the equipment. Among them, shaft couplings are usually used for the connection between shafts. If the disassembly and assembly of the couplings can be completed quickly and efficiently during the maintenance process, the maintenance time can be greatly reduced, thereby improving the maintenance efficiency. [0003] During coupling disassembly, the coupling bolts are removed first, and then the hub is removed from the shaft. One of the more difficult to disassemble the hub. Usually, a three-legged puller or a four-legged puller is used to remove the hub. The selected puller matches the outer dimensions of the wheel hub. After the right-angle...
