Problems solved by technology

[0006] The invention provides a magnetic governor for remote and automatic radial air gap control. Through the research on the speed regulation structure, it not only realizes the purpose of the stepless speed change of the coupling itself, improves the transmission efficiency of the magnetic coupling, but also improves the transmission efficiency of the magnetic coupling. It solves the problem of motor heating and even failure due to excessive induction current when the motor load is started, and realizes the soft start function of the motor; through the research on the transmission mechanism composed of the inner and outer rotor assemblies, it proposes a motor that can provide stable rotation in different occasions. The transmission mechanism of torque and power expands the scope of use of magnetic couplings

Embodiment 1

[0035] Realize the soft start of the motor: when starting the motor, move the movable card body 7 to the maximum outer diameter by automatically controlling the stepping motor 4, so that the motor and the load can be separated to the maximum, the motor starts with no load or low load, and when the motor is running After stabilization, the system is driven by a stepping motor The radial distance between the permanent magnet 8 and the guide bar 13 is adjusted to a predetermined position, thereby avoiding the problem of rapid heating and even failure of the motor due to the excessive slip rate and the induction of a large current during the load startup process.

[0036] The working principle of embodiment 2: on the basis of embodiment 1, the guide bar 13 in the inner rotor assembly is replaced with the outer layer copper skin 30 wrapped on the inner layer solid rotor 31, when the step controller 20 sends a positive When turning the signal, the stepping driver 23 receives a posi...

Abstract

The invention relates to the field for the transmission technology of mechanical engineering, specifically to a magnetic governor with remote automatic control of radial air gap, wherein the rotation and displacement of a stepper motor is accurately controlled by controlling impulse frequency, the radial displacement of a movable clamping body is controlled by means of gear transmission and thread transmission, the radial distance between a permanent magnet and a conducting bar can be adjusted accurately, different rotate speed and torque are output, and the purpose of stepless speed change of a coupler is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering transmission, in particular to a magnetic governor for remote and automatic radial air gap control, which is mainly used for power transmission between motors and loads in industries such as oil refining, chemical industry, coal, and power generation, and other devices . technical background [0002] In the field of mechanical engineering transmission technology, the coupling is an important part of the mechanical transmission system. With the continuous development of science and technology, the application range of the coupling is becoming wider and wider; in the traditional mechanical transmission system, due to the The mechanical connection method requires high centering accuracy between devices, which is very difficult for large-scale equipment or high-precision transmission systems. Once there is an error in the alignment, the transmission system may be twisted during work. T...
