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 invention provides a magnetic gear comprising gear bodies and magnetic sources. The gear bodies comprise 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. The middle parts of the first magnetic source of the first magnetic source array and the second magnetic source of the second magnetic source array cooperate to generate attraction force along the axial directionof the gear bodies. The two ends of the first magnetic source and the second magnetic source cooperate to generate repulsive force respectively. The repulsive force and the attraction force are simultaneously generated between the magnetic sources on the working position. The driving force of the driving gear for driving the driven gear to rotate is improved by generating the repulsive force on both ends of the magnetic sources, and the transmission stability between the gears is improved. The phase alignment in case of engaging between the gears can be realized through the attraction force generated in the middle of the magnetic sources, and the engaging reliability of the gears can be improved.

Description

technical field [0001] The invention relates to a novel magnetic gear. Background technique [0002] In the traditional transmission area, mechanical gear is the most widely used transmission mechanism. Traditional gears rely on the meshing of their respective teeth for transmission, but mechanical gears have many disadvantages, 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 have several pairs of N and S magnetic poles alternately distributed on the surface of the gear annular cylinder, and the transmission between the gears is carried out by using a single pole between the magnetic poles. However, this kind of magnetic gear has a low bearing capacity and cannot adapt to higher transmission spe...
