Abstract

The invention provides a main transmission motor disassembly method which includes the step: lifting a rotor of a main transmission motor to a first preset position, and stopping lifting the rotor; jacking a stator of the main transmission motor to a second preset position, and stopping jacking the stator; repeatedly lifting the rotor and jacking the stator, and stopping lifting the rotor and jacking the stator until a stator hole of the main transmission motor and a foundation bolt of an equipment foundation are separated. The stator of the main transmission motor is connected with the equipment foundation through the foundation bolt. According to the method, the main transmission motor can be disassembled from the equipment foundation by the aid of relatively small force, the stator andthe rotor of the main transmission motor can be effectively protected, damage of the main transmission motor is avoided, and the main transmission motor and the equipment foundation can be safely separated without damaging the main transmission motor and corresponding construction devices even if the foundation bolt and the stator hole are clamped.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance, in particular to a method for disassembling a main drive motor. Background technique [0002] During the inspection and maintenance of the main drive motor of the rolling mill in the industrial production line, it often occurs that the installation technology of the main drive motor is not up to standard during the early installation, resulting in corresponding quality problems. These problems will bring certain difficulties to the maintenance construction. For example, the stator of the main drive motor has a stator hole. The connection between the main drive motor and the equipment foundation is to set anchor bolts on the equipment foundation. Phase screw connection. When the main drive motor is overhauled, the main drive motor needs to be disassembled from the equipment foundation. However, after the nuts of the anchor bolts are removed, it is often found that the anchor bolts ...
