Description

Technical Field

[0002] As a highly efficient transmission device, the double-barrel permanent magnet speed regulator is widely used in the industrial field. It realizes power transmission through magnetic coupling and has the advantages of contactless, low maintenance, energy saving and environmental protection. It has a conductor rotor assembly and a permanent magnet rotor assembly. The conductor rotor assembly is a double-barrel structure, and the permanent magnet rotor assembly is a single-barrel structure, and its single-barrel will extend between the two cylindrical structures of the double-barrel. During the installation of the double-barrel permanent magnet speed regulator, it is very important to ensure the precise coaxial alignment of the double-barrel part and the single-barrel part, which is not only related to the operating efficiency of the speed regulator, but also directly affects the stability and service life of the equipment.

[0056] Specifically, the coaxiality can be ensured in the following two ways:

[0057] Method 1: a transverse slide rail is provided on the lower side of the input motor to be connected, and the input shaft and the output shaft to be connected are adjusted to be coaxial, and a laser instrument can be used to assist in alignment; during the movement of the input motor, the input shaft and the output shaft are always kept coaxial, which is particularly suitable for the existing movable double-barrel permanent magnet speed regulator;

[0058] Method 2: First, adjust the intermediate assembly by a crane or a three-degree-of-freedom adjustment device so that the second mounting disk 21 is coaxial with the input shaft to be connected; then, with the assistance of the first laser emitter 7 and the second laser emitter 8, adjust the input shaft to be coaxial with the first mounting disk 11, thereby achieving coaxiality between the input shaft and the output shaft.

[0059] S4. Remove the double-cylinder permanent magnet speed regulator installation auxiliary device; loosen the double-cylinder part and the single-cylinder part through the first positioning component 1 and the second positioning component 2, and withdraw the double-cylinder part and the single-cylinder part through the telescopic component 3.
