Abstract

The invention discloses a magnetic gear shift capable of conducting separation and reunion and belongs to the field of transmissions. The magnetic gear shift aims to solve the problem that an existing transmission cannot meet requirements when a clutch is needed. The magnetic gear shift comprises a stator, an electro-magnetic rotor and a permanent magnet rotor. A shaft of the electro-magnetic rotor and a shaft of the permanent magnet rotor are concentric, and the electro-magnetic rotor and the permanent magnet rotor are arranged side by side in the stator. The stator comprises a front end cover, a rear end cover, a case, P1 stator magnetic poles and a supporting ring. The electro-magnetic rotor comprises an electro-magnetic spindle, an electro-magnetic rotor yoke and P2 pairs of electro-magnetic magnetic poles. The permanent magnet rotor comprises a permanent magnet spindle, a permanent magnet rotor yoke and P3 pairs of rotor permanent magnet magnetic poles. The magnetic gear shift meets the equation: P3= .

Description

technical field [0001] The invention relates to a clutchable magnetic transmission and belongs to the field of transmissions. Background technique [0002] Existing drive systems usually employ a mechanical gearbox as the speed change device between the prime mover and the load. Its outstanding disadvantages are severe mechanical shock and wear, high noise and bulky size. The permanent magnet magnetic transmission made of high-efficiency rare-earth permanent magnet material can use magnetic force for non-contact transmission and speed change, which overcomes the above-mentioned shortcomings. In some application occasions, when the prime mover is required to stop rotating, the load stops rotating. At this time, a clutch is generally used, but the general clutch has no function of shifting. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing transmission cannot meet the requirements under the condition that a cl...
