Problems solved by technology

[0002] At present, the ordinary speed change mechanism generally adopts a mechanical transmission structure, and realizes the speed change function through the gear ratio of the worm wheel, the screw, or the large and small gears. Due to the large mechanical friction of this kind of speed change mechanism, there is a large friction in the power transmission process. Problems of mechanical friction, power loss and working noise. At the same time, in order to ensure the service life of the transmission mechanism, ordinary reducers need to be filled with lubricating oil or grease for lubrication, and regular maintenance is required
Therefore, the common transmission mechanism has problems such as large power loss and short service life.

Abstract

The invention relates to a permanent magnet transmission speed change mechanism. A swing disc arranged on an eccentric shaft is matched with an outer rotor, and the number of permanent magnet steel sheets of the swing disc and the number of permanent magnet steel sheets of the outer rotor are different. When the swing disc swings in an annular shape, the rotor is made to rotate through the actingforce of opposite attraction of the permanent magnet steel sheets. The gear ratio of the speed change mechanism is determined by the difference value of the number of the permanent magnet steel sheetsarranged on the rotor and the number of the permanent magnet steel sheets arranged on the swing disc, and a large gear ratio can be easily achieved. The speed change mechanism has the advantages of quite high power transmission efficiency, large-range gear ratio, almost no mechanical friction and transmission loss during power transmission besides weak loss of the bearing, simple structure, smallvolume, low weight, no need of lubricating oil, no need of periodic maintenance, long service life and the like.

technical field [0001] The invention relates to a speed change mechanism technology, in particular to a speed change mechanism for permanent magnet transmission. Background technique [0002] At present, the ordinary speed change mechanism generally adopts a mechanical transmission structure, and realizes the speed change function through the gear ratio of the worm wheel, the screw, or the large and small gears. Due to the large mechanical friction of this kind of speed change mechanism, there is a large friction in the power transmission process. Problems of mechanical friction, power loss and working noise. At the same time, in order to ensure the service life of the transmission mechanism, ordinary reducers need to be filled with lubricating oil or grease for lubrication, and regular maintenance is required. Therefore, the common transmission mechanism has problems such as large power loss and short service life. Contents of the invention [0003] The purpose of the ...
