Description

Air gap adjusting mechanism for permanent magnet and copper conductor of permanent magnet coupler

Technical Field

The utility model belongs to the technical field of permanent magnet couplers, and particularly relates to an air gap adjusting mechanism of a permanent magnet coupler and a copper conductor.

Background

The permanent magnet coupler is a novel coupler for connecting a prime motor and a working machine through the magnetic force of a permanent magnet body, and the permanent magnet coupler does not need direct mechanical connection, but utilizes the interaction between rare earth permanent magnet bodies and utilizes the characteristic that a magnetic field can penetrate a certain space distance and a material to transmit mechanical energy. The magnetic coupling thoroughly solves the leakage problem of dynamic sealing in some mechanical devices. The magnetic coupling is widely applied to sealing transmission machinery in the industries of chemical engineering, electroplating, papermaking, pharmacy, food, vacuum and the like, and mainly comprises an outer rotor, an inner rotor and a spacer sleeve.

At present, most of the connection between a motor and a load belongs to mechanical connection, the mechanical connection is driven through a mechanical structure, abrasion is likely to occur in the mechanical connection under a long-time working state, and further transmission efficiency and transmission stability are reduced, so that a permanent magnet coupling machine gradually replaces the mechanical connection for transmission between the motor and the load, the torque transmission size and the speed transmission size of the permanent magnet coupling are related to the gap between the permanent magnet body and the copper conductor body inside the permanent magnet coupling, the permanent magnet coupling is driven to move through mechanical force in a traditional mode for adjusting the gap, external parts are likely to be required to contact with the permanent magnet body through mechanical force, normal rotation of the permanent magnet body is easy to interfere, and damage is likely to be caused to the permanent magnet body in the adjusting process, so that certain defects exist.
