Linear movement core sleeving assembly method of large motor stator

Abstract

The invention relates to the technology of large motor assembly, in particular to a linear movement core sleeving assembly method of a large motor stator. The method is characterized in that the stator is placed on a roller type transferring device, is enabled to be capable of linearly moving along the roller type transferring device, and is pushed so as to complete core sleeving. The method includes the specific steps: 1) lifting the motor stator to be placed on the roller type transferring device; 2) temporarily connecting a rotor with an extended shaft; 3) disposing a first temporary support and a second temporary support; 4) lifting the rotor to penetrate the stator, and after the stator is penetrated, carrying the shaft end of the extended shaft on the first temporary shaft, and carrying the other end of the motor rotor on the second temporary shaft; 5) controlling the coaxiality of the stator and the rotor to be not larger than 5mm; and 6) moving the stator and completing core sleeving assembly. Compared with the prior art, the method has the advantages that general assembly of large motors of various specifications can be met, and vibration, swing and collision generated along with linear movement of the rotor in a core sleeving assembly process of the large motor are eliminated.

Description

technical field [0001] The invention relates to the field of assembling large-scale motors in industrial installation engineering of metallurgical systems, in particular to a method for assembling a large-scale motor stator linearly moving sleeve core. Background technique [0002] In enterprises without large-scale motor stator and rotor assembly equipment, the rotor is usually directly hoisted by a crane for core sleeve operation. The disadvantage is that there is vibration during the movement of the rotor, which is prone to collision between the stator and rotor magnetic poles, or high In case of a fall accident, the main steps of the operation process are as follows: [0003] Step 1: First fix the long shaft on the rotor, then put the stator at a position parallel to the crane trolley, lift the rotor by the crane, slowly insert the rotor into the stator, and the long shaft to be connected goes out of the other end of the stator , adjust the height of the center of the r...

Problems solved by technology

[0002] In enterprises without large-scale motor stator and rotor assembly equipment, the rotor is usually directly hoisted by a crane for core sleeve operation. The disadvantage is that there is vibration during the movement of the rotor, which is prone to collision between the stator and rotor magnetic poles, or high In case of a fall accident, the main steps of the operation process are as follows:

Its shortcoming is that it uses two rail trolleys with supporting lifting devices to support the linear movement of the rotor. The structure of the equipment is complex, and the location of the rail trolleys occupies a large area, which requires installation and adjustment. The shaft is lengthened, and there is also the problem of vibration during the movement of the stator and rotor of the large motor, which is inconvenient for the final assembly
