Disk-type permanent-magnetic speed governor without bearings

Abstract

The invention relates to a disk-type permanent-magnetic speed governor without bearings, comprising a conductor plate, a conductor plate flange, a permanent magnet plate, adjusting screws, locking nuts, a spline shaft, and a permanent magnet plate flange. The conductor plate and the permanent magnet plate are flat plates. The conductor plate is provided with two conductor rings, permanent magnet blocks are embedded into the permanent magnet plate, and the permanent magnet blocks in the permanent magnet plate and the conductor rings on the conductor plate are arranged correspondingly. The conductor plate is fixedly connected with a motor shaft through the conductor plate flange. The permanent magnet plate is fixedly connected with the permanent magnet plate flange which is provided with an internal spline. The permanent magnet plate flange and the spline shaft are in sliding connection through the spline. The spline shaft is fixedly connected with a load shaft. The two ends of the adjusting screws are respectively in threaded connection with the permanent magnet plate flange and a spline shaft flange. The locking nuts are in threaded connection with the adjusting screws. The two ends of the adjusting screw are respectively forward and reverse threads. The internal threads of screw holes matching the adjusting screws on the permanent magnet plate flange and on the spline shaft flange match the forward and reverse threads.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet speed regulation, and in particular relates to a bearingless disc permanent magnet speed governor, which can be applied to a non-contact mechanical transmission system with high torque and low speed, and has the advantages of off-line adjustment, simple structure, low cost, The advantage of being maintenance-free. Background technique [0002] The permanent magnet coupler is widely used in various industries as an electromagnetic transmission mechanism. It realizes the torque transmission from the motor to the load through the air gap between the conductor and the permanent magnet, and can realize the non-mechanical connection between the motor and the load. Transmission, which has many advantages such as adjustable transmission torque, high transmission efficiency, flexible start, vibration isolation, etc. The basic structure of the existing permanent magnet coupler is composed of a cond...
