Abstract

The invention provides a magnetic gear. The magnetic gear includes gear teeth and gear grooves. Each gear tooth includes a first contact surface, a second contact surface and a tooth tip. Each first contact surface is provided with a first magnetic source. Each second contact surface is provided with a second magnetic source. Each tooth tip is provided with a third magnetic source. Each gear groove is provided with a fourth magnetic source. The first magnetic sources and the second magnetic sources are used for generating repulsive force when two magnetic gears engage. The third magnetic sources and the fourth magnetic sources are used for generating attractive force when two magnetic gears engage with each other. The magnetic sources are arranged in the structure of the magnetic gear. Theforce of the magnetic sources facilitates the high-rotating speed drive of the magnetic gear. The magnetic sources arranged on the contact surfaces that the magnetic gears engage with each other areused for generating repulsive forces. The repulsive force among the magnetic sources helps to reduce the resistance and the wear of the magnetic gear and prolong the life of the magnetic gear. The magnetic sources arranged at the tooth tips and the gear grooves are used for generating attractive force, which facilitates the calibration of the engaging positions of the magnetic gear and improve theaccuracy of the drive of the magnetic gear.

Description

technical field [0001] The invention relates to a novel magnetic gear, and a magnetic gear transmission and a motor with the magnetic gear. Background technique [0002] Magnetic gears are wheel-shaped mechanical parts that transmit torque by the meshing of teeth. Due to the advantages of high transmission efficiency, accurate transmission ratio, and large power range, magnetic gear mechanisms are widely used in industrial products, and their design and manufacturing levels directly affect the quality of industrial products. The teeth of the magnetic gear are interlocked, and the magnetic gear will drive the other magnetic gear to rotate to transmit power. [0003] Today's magnetic gears are driven by meshing between two magnetic gears. There are contact surfaces with hard contact, and the load is large. When subjected to violent impact, it is easy to cause wear of the magnetic gears, reduce the transmission accuracy of the magnetic gears, and thus reduce the transmission e...
