An adjustable-speed magnetic-gathering double-tube asynchronous magnetic coupler

Abstract

The invention relates to the technical field of transmission in mechanical engineering, in particular to a speed-adjustable magnetic concentrating double-cylinder asynchronous magnetic coupler. The magnetic coupler is composed of a driven rotor assembly, a driving rotor assembly and a speed adjustment device assembly. Permanent magnets are closely stuck on the outer surface of an inner matrix and the inner surface of an outer matrix of a driven rotor. Every two adjacent permanent magnets constitute a magnetic pole, wherein one magnet is magnetized in the radial direction, and the other magnet is magnetized in the tangential direction. The adjacent surfaces of the magnets magnetized in different directions tilt by an angle of alpha. Fan-shaped transparent slots are machined at an interval of certain radian along the circumference of a copper ring. Cast iron blocks with the same shape as the fan-shaped transparent slots are embedded into the slots. Threaded holes are machined in the sides of the copper ring and the cast iron blocks. The cast iron blocks are fixedly connected with the copper ring through countersunk head screws. A servo motor works and drives a double-headed cylindrical cam to rotate. The cylindrical cam drives left and right driven rotors to move along a connecting rod in the same direction or in opposite directions through a sliding rod. Thus, the relative meshing area of the permanent magnets and the copper ring is changed. The speed adjustment function of the magnetic coupler is achieved.

[0002] In the field of mechanical engineering, transmission technology is one of the most basic and important parts. It involves various fields of the machinery industry and is widely used in mining, metallurgy, aviation, weapons, hydropower, chemical industry, textile and transportation departments. Traditional transmission technology Due to the rigid connection, friction and wear will occur during operation, which will affect the power transmission efficiency and cause energy waste. In addition, it is easy to produce radial and angular offsets during installation, which will generate alternating loads and cause vibrations, which will reduce coupling at least slightly. The service life of the device is seriously affected, and the normal operation of the equipment is seriously affected. As a form of new transmission, the magnetic coupling uses the magnetic force generated by the permanent magnet material to realize the non-contact transmission of torque and reduces the loss of transmission components. , prolong the service life of related components, based on the above advantages, magnetic couplings have gradually replaced mechanical couplings in some fields to transmit torque and power

However, compared with the traditional coupler, the load capacity of the magnetic coupler is not strong. Therefore, realizing the high power and high torque output of the magnetic coupler is an important research direction to expand its application range.
