AI Technical Summary

Technical Problem

The existing vacuum pump rotor and blades have poor wear resistance, and the connection between the rotor and the drive motor is inconvenient, resulting in insufficient service life and connection stability.

Method used

A wear-resistant protective coating is applied to the guide slot of the rotor body, and a connecting slot and a connecting frame are designed on the rotor body. A stable connection is achieved by inserting the connecting frame into the mounting slot. Connecting bearings and sealing rings are used in combination to improve wear resistance and ease of installation.

Benefits of technology

It enhances the wear resistance of the rotor assembly, improves service life and installation stability, reduces weight, and improves transmission efficiency.

Abstract

This utility model discloses a vacuum pump rotor assembly structure, including a rotor body. Guide slots are provided at the top and bottom of the outer surface of the rotor body, and the inner surface of the guide slots is coated with a wear-resistant protective coating. A mounting slot is provided on one side of the rotor body, and a connecting column is integrally formed within the mounting slot. A connecting bracket is fitted onto the outer surface of the connecting column. This utility model, through the design of the wear-resistant protective coating within the guide slots, provides wear protection for the rotor body, preventing wear caused by the sliding of blades within the guide slots and ensuring the service life of the rotor assembly structure. The removable connecting bracket within the mounting slot allows operators to connect the motor to the vacuum pump motor first, and then place the connecting bracket in the mounting slot. This movable connection method facilitates the installation of the rotor assembly structure on the vacuum pump.
