AI Technical Summary

Technical Problem

When installing the rotor of a small generator, the rotor's shaking and misalignment make it difficult to align the bearings, and the rotor is easily damaged by collision with the stator, affecting the dynamic balance accuracy and assembly quality.

Method used

A round rod is installed in the iron core of the rotor body, and the rotor body is introduced into the stator through the round rod guide. The round rod is fixed by threaded connection to stabilize the rotor position and prevent shaking. After installation, lubricating oil is injected for lubrication and support.

Benefits of technology

It achieves the stability of rotor installation and prevents winding damage, improves installation efficiency and dynamic balancing accuracy, and reduces the risk of rotor damage.

Abstract

The present invention relates to a high-speed motor rotor mounting structure, comprising a rotor body, wherein the rotor body comprises an iron core, a winding is provided on the outside of the iron core, and a bearing is mounted on one end of the iron core, a circular groove is provided through the iron core, a round rod is inserted through the circular groove, the rotor body is mounted in a stator, a bearing groove is provided in the stator, and the bearing is slidably inserted in the bearing groove. The present invention mounts the round rod in the iron core of the rotor body, and during installation, first inserts one end of the round rod into the round rod positioning groove, then aligns the circular groove of the iron core with the round rod, and inserts the round rod into the circular groove. Under the guidance of the round rod, the rotor body is pushed to enter the stator, thereby preventing the rotor body from shaking when entering the stator. Moreover, due to the guidance of the round rod, the round rod plays a supporting role when the rotor body is inserted into the stator. After the rotor body is installed, the round rod is removed, effectively preventing the winding from being damaged.
