Problems solved by technology

However, this gear is only suitable for gear transmission at low speeds, and cannot adapt to high-speed gear transmission.
If high-speed transmission is carried out, it is easy to cause meshing misalignment and damage the gears

Abstract

The present invention provides a magnetic gear, which includes a gear body and a magnetic source. The gear body includes a first gear body and a second gear body, a first magnetic source array is uniformly distributed along the circumferential direction of the first gear body, and a second magnetic source array is uniformly distributed along the circumferential direction of the second gear body. Along the axial direction of the gear body, the first magnetic source of the first magnetic source array cooperates with the middle of the second magnetic source of the second magnetic source array to produce an attractive force; the two ends of the first magnetic source and the second magnetic source cooperate to produce repulsion respectively. force. In the working position, repulsive force and attractive force are simultaneously generated between the magnetic source and the magnetic source. The repulsive force is generated at both ends of the magnetic source, the driving force for driving the driven gear to rotate by the driving gear is improved, and the stability of the transmission between the gears is improved. Through the attractive force generated in the middle of the magnetic source, the phase alignment when the gears are engaged with the gears is realized, and the reliability of the gear engagement is improved.

Description

technical field [0001] The present invention relates to a novel magnetic gear. Background technique [0002] In the traditional transmission area, mechanical gears are the most widely used transmission mechanisms. Traditional gears rely on the meshing of their respective gear teeth for transmission, but mechanical gears have many shortcomings, such as vibration, loss, periodic lubrication, etc., which often limit the further improvement of the performance of the transmission system. For this reason, magnetic gears appear in the transmission system, which are used to replace the work of mechanical gears to a certain extent. [0003] The magnetic gears that appear today are alternately distributed with pairs of N and S magnetic poles on the surface of the gear ring cylinder, and the transmission between the gears is carried out by using the single magnetic poles. However, this kind of magnetic gear has a low bearing capacity and cannot adapt to a higher transmission speed. ...
