Internal radiation ring static speed regulation protection type permanent magnet coupler

Abstract

An internal radiation ring static speed regulation protection type permanent magnet coupler is composed of a conductor outer rotor I, a permanent magnet inner rotor II, a meshing face adjustment mechanism III and an intelligent protection system IV. The conductor outer rotor I is connected with a motor shaft through a motor shaft expansion sleeve, and motor power is led by a motor shaft chain. The permanent magnet inner rotor II is connected with a load shaft through a load shaft expansion sleeve, and torque is output through a load shaft chain. Under a static state, the meshing face adjustment mechanism III is adjusted manually, and therefore the size of meshing area of the conductor outer rotor I and the permanent magnet inner rotor II can be changed. A signal coded disc is arranged on a signal detection shaft on a load side and used for detecting load rotation speed change in real time. The internal radiation ring static speed regulation protection type permanent magnet coupler is characterized in that when the conductor outer rotor I rotates at a high speed, an outer copper ring in a single ring induction body cuts a magnetic force line of an internal radiation type integrated magnetic ring in the permanent magnet inner rotor II through radial fixed air gaps so that vortex can be generated on the outer copper ring, and meanwhile, the vortex generates an induced magnetic field to be in interaction with a permanent magnetic field to achieve power connectionless transmission.

Description

technical field [0001] The invention relates to a motor shaft coupling device, which is suitable for the connection between the motor and the load under the working conditions of frequent starting of the motor, frequent load change, severe overload and adjustment of the output of the load. Background technique [0002] Couplings are frequently used components in the power transmission process of mechanical systems, and are widely used in petrochemical, power industry, mining and shipping, aerospace, steel industry, papermaking and other industries. With the continuous development of science and technology, the application field of couplings has been continuously expanded, and the technology has also been continuously developed, and new products and technologies have emerged in an endless stream. [0003] There are many types of couplings, which are usually divided into rigid couplings and flexible couplings according to whether they have the ability to compensate for relati...
