Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the figure, the present invention includes an outer flange 1 and a fixed sleeve 2. The outer flange is provided with a butt joint 4, and the outer flange 1 and the fixed sleeve 2 are connected by a butt stop The mouth is fixed as a whole; the fixed sleeve is provided with a threaded hole, and a bolt 3 is arranged in the threaded hole, and the rotor shaft 5 is sleeved in the fixed sleeve 2 and fixed by the bolt; the outer flange is arranged in the stator core, And the outer diameter of the flange is 1-2mm smaller than the inner diameter of the stator core.

[0013] There are multiple threaded holes, which are evenly arranged along the circumference of the fixing sleeve.

[0014] In order to reduce weight, the outer flange is provided with a plurality of through holes, which are evenly distributed.

[0015] The use method of the present invention is: fix the...

Abstract

The invention discloses a motor rotor assembly guiding method. A rotor penetrates a through hole of a positioning flange, and the outer diameter of the positioning flange is smaller than the inner diameter of a stator core; and the positioning flange is used to avoid the offset for the attraction of the rotor caused by the magnetic force. The motor rotor assembly guiding method ensures that the center line of the rotor shaft is in a line so that the rotor is smoothly assembled into the stator.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a motor rotor shaft assembling method and a device for realizing the method. Background technique [0002] The low-speed high-torque permanent magnet motor adopts the latest electromagnetic scheme and structural scheme. The stator is a normal coil structure, and the permanent magnet is installed in the rotor slot. Due to this structure, the permanent magnet in the rotor slot has a large suction force, and it is very difficult to assemble the rotor into the stator. , cannot be corrected. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a mounting mold for the circumferential rotor shaft, and the specific technical solutions are as follows: [0004] A method for assembling and guiding the rotor of a motor, characterized in that: the rotor is put through the through hole of the positi...
