Description
Technical field
The invention belongs to technical field of driving, and in particular to a kind of high-temperature superconductor non-contact transmission mechanism.
Background technique
In the prior art, transmission device is essentially relying on addition shaft coupling, bearing, friction between motor and workpiece
The components such as wheel, gear, lead screw, to realize transmission of the power from motor to workpiece.This kind of drive utilizes machinery
Mode transmits power, and machine driving is generally divided into two classes: first is that the friction of the frictional force transmitting power between parts and movement passes
It is dynamic.Second is that the engaged transmission of transmitting power or movement is engaged or engaged by middleware with driven member by driving link.These two types of machines
The tool kind of drive has a very wide range of applications, but mechanical drive mode because its structure is simple, technology maturation in mechanical engineering
There is also clearly disadvantageous, i.e., presence frictions between motor and transmission parts, each transmission parts, transmission parts and workpiece
Power, therefore, in transmission process inevitably there are mechanical friction, component wear, generate heat, have the problems such as noise.These
Need to be added stability of the modes such as lubrication, cooling to improve operating toward contact between component, vulnerable to external working environment because
The influence of element, can not also work under some harsh environments.Simultaneously because in transmission system lubricating oil, coolant addition,
So that it is not suitable for the working spaces such as constant temperature, noiseless, dustless yet.
And the contactless kind of drive can largely solve frictional dissipation caused by conventional mechanical transmission mode
The problems such as.For example, application No. is 200910062234.8 patent of invention, by using pole pair in the junction of transmission parts
The permanent magnet answered, or replaced with electromagnetic induction facilities such as the electromagnets of magnetic adjustable variation, constitute a kind of electromagnetism sense
It should gently contact and non-contact magnetic transmission structure, realize light contact and contactless transmission；Authorization Notice No. is CN
The patent of invention of 203823001 U is by introducing permanent magnetic rotation disc and conductor turntable, so that permanent magnetic rotation disc is acted on by electromagnetic induction
Power mode and the transmission of conductor turntable cooperate, and realize touchless transmission；Authorization Notice No. is the hair of 206226258 U of CN
Bright patent, so that driving wheel and follower do not contact while intermeshing again, is realized non-contact by introducing permanent magnet gear
Magnetic drives speed change.
But though these above-mentioned patents to overcome abrasion, broken teeth, noise present in the existing machinery kind of drive larger etc.
Problem, but since these above-mentioned kinds of drive generally use between permanent magnet or electromagnet the original of " identical charges repel each other, and there is a natural attraction between the sexes "
The characteristics of reason, and the active force between permanent magnet is obvious with distance change, and stability is poor, " attract or repel " makes
Transmission process is obtained to be not sufficiently stable and accurately, need to bear bigger come from so as to cause the bearing connecting in operational process with magnet
Lateral power, so that bearing fluctuation of service, also more easy to wear.
