Description
Technical field
The present invention relates to a kind of Gear Planet Transmission reductor, specifically, relate to a kind of magnetic floating star transmission gear shift machine.
Background technology
Traditional gear drive mainly relies on the engaging force of mechanical gear to realize the transmission of moment of torsion and speed, the moment of its transmission, only have two tooth contact actings, thus wearing and tearing, noise, vibration can be produced, and other tooth does not do work, the utilance of gear is low, is the operation of safeguards system simultaneously, lubricating oil need be added use as lubrication and cooling, easy contaminated environment.Therefore traditional gear drive machine cannot use in the environment that some are special, as the field such as food manufacturing, space flight.
For solving traditional gear-driven shortcoming, eighties of last century has had inventor to propose to utilize the magnetic of electromagnetic driven to float transmission, as magnetic coupling centrifugal pump, it comprises the centrifugal motor of a Magnetic drive, and motor is made up of a permanent magnetosphere of annular and soft ferromagnetic polar circle.Because the magnetic force at that time because of magnet limits, the magnetic that there is no high pulling torque floats transmission mechanism and occurs.
In 1973, American scholar Mallianson found a kind of peculiar permanent magnet structure when carrying out assembled experiment to permanent magnet structure, and it is called " MagneticCuriosity ".1979, American scholar KlausHalbach recycled magnetic field that various permanent magnet structure produces when doing Accelerating electron experiment, has found this special permanent magnet structure, and this structure of gradual perfection, has finally defined so-called " Halbach " magnet.Halbach magnet ring magnet radial and run-in index is arranged to combine, if ignore end effect, and the permeability of the permeability magnetic material of surrounding is regarded as infinity, so above-mentioned magnet structure finally forms monolateral magnetic field (one-sidedfield), Halbach feature shown that Here it is.Halbach type permanent magnet array can improve air gap flux density, and is easy to the air-gap field obtaining sinusoidal pattern distribution, reduces torque ripple, reduces yoke portion magnetic flux.The moment of torsion that the increase of air gap flux density makes electromagnetic torque increase, transmit improves, due to yoke portion magnetic flux reduce can corresponding few with or without yoke portion, this can reduce the volume and weight of mechanism.
At present, we retrieve the open source literature of some magnetic coupling transmission devices, such as:
