Abstract

Provided is a magnetic force non-contact transmission device formed by using magnetic bodies, electromagnets or permanent magnets in a plurality of combination modes. According to the modes, the magnetic bodies, the electromagnets or the permanent magnets can be arranged to form disks A and B which are of the same size, or form two cylinders A and B which are sleeved with each other, or form two circular shafts A and B which are of the equal diameter and the same length. A plurality of small magnetic bodies which are the same in shape, size and weight are used, gaps are evenly distributed on the small magnetic bodies, the small magnetic bodies are respectively embedded on two butt joint carrier surfaces A and B in a face-to-face mode, the small magnetic bodies orderly arranged on the surfaces A and the small magnetic bodies orderly arranged on the surfaces B correspondingly generate small magnetic force combination points, the points are added to combine an integrally powerful magnetic field, power is transmitted from one surface of A to one surface of B, and one surface of B can also perform reaction to achieve stop. A certain gaps are reserved on one surface of A and the middle of B during arrangement, transmission depends on magnetic attraction or repulsive force, and the non-contact transmission effect is achieved.

Description

Magnetic combination is noiseless, nothing wearing and tearing transmission device

Technical field

The present invention relates to a kind of force actuators, the transmission device that adopts exactly magnetic force to finish.

Background technology

The transmission of power generally is to finish with forms such as gear, belt, chains at present.

The gear that adopts in the existing force actuators, belt or chain, at work because friction can produce noise, also can produce high temperature when lacking lubricant damages even, also can damage during excess load, the time grown also can owing to abrasion deformation be directed at driving force deficiency and must not since can produce cost with new replacement and strengthen.

Summary of the invention

The objective of the invention is the gear, belt or the chain that adopt in the existing force actuators, when work, can produce noise, heating, wear and tear these defectives and adopt the inducing function of magnetic force and obtain the not Contact Transmission of power.

For realizing contactless power transmission purpose; the present invention adopts the magnet of a plurality of fritters; the optional electromagnetism of using; also can select permanent magnetism; the magnet of these fritters is separately fixed on A and two interfaces of B; the magnet of these fritters must be same shape; volume; the face of weight and docking all is just the same; can make as required circle; square; triangle; strip; but must be that circle is to circle; side the other side; triangle is to triangle; rectangular to rectangular; these small magnets are embedded in respectively uniformly on the carrier of A and two contact-making surfaces of B; small magnet on the A face must with the B face on small magnet each and every one is corresponding; these small magnets in pairs will produce combination force one by one when docked on the two sides like this; produce again a large group face by the combined spot addition of this one and close integral body; and obtain a powerful field of magnetic forece; will make the power on the A face pass to the B face; all the time leave certain gap between A face and the B face during work; can not produce noise like this; high temperature or wearing and tearing; the size in gap is arranged to adjustable; be used for changing driving force, can protect again the damage of power source and parts.

Embodiment

The present invention will be illustrated by reference to the accompanying drawings by preferred embodiment.

With reference to accompanying drawing 1, to adopt disc type magnetic force mode of transfer force, the front that is embedded in A dish and B dish that the fritter magnet of exactly will be one by one same shape, same volume, same weight is uniform sequential, the front of requirement and disk is a plane, small magnet on the A dish leaves certain interval between each, small magnet on the B dish also leaves a gap the same with A dish, can guarantee that the magnet on the A dish is corresponding with each piece of magnet on the B dish, and the size in gap is not take interfereing with each other as good magnetic force.Small magnet can be made conglobate, square, rectangular or triangle as required, select suitable shape, present case has selected to use the strip small magnet, and A dish and B dish approach during work, but leave all the time a stable spacing, so just can not produce noise, high temperature or wearing and tearing.

Accompanying drawing 2, to adopt the mode of great circle jacket casing roundlet cylinder to obtain magnetic drives, be exactly to incite somebody to action one by one same shape, weight, volume is all on the uniform sequential inwall that is embedded in the A cylinder of duplicate small magnet, leave certain interval between every, then be embedded on the outer wall of B cylinder with same small magnet, leave between every with the A cylinder on the gap that equates of small magnet, guaranteeing small magnet on small magnet and the B cylinder on the A cylinder, each and every one is corresponding, the size in gap is not to interfere with each other magnetic force as good, these small magnets can be made into various shape, what present case was selected is circular small magnet, and A cylinder inwall and B drum outer wall have a gap all the time during work.

Accompanying drawing 3, to do magnetic drives with two the same circular shafts, the fritter magnet of same shape, same weight, same volume neatly is embedded in around the surface of A axle uniformly one by one exactly, require smooth, and leave certain interval between every, be embedded in around the surface of B axle with the small magnet of same shape and quantity, leave the gap the same with the A axle between every, can guarantee that the small magnet of another axle when a circular shaft rotates each and every one relatively just should.Two circular shafts having made are just the same.Also can adopt two with two circular shafts long equally, the same wide with two diameter of round spindle, have certain thickness rectangular magnets to be individually fixed in two circular shaft centers.This mode effect is also very desirable, and A axle and B axle are orderings arranged side by side in the work, and be at regular intervals between the diaxon, can not produce noise, temperature, damage like this.

More than three cases have common magnetic combination principle, it all is the maximum using that an one by one little combined spot addition large combinatorial surface of integral body of formation is obtained magnetic force, in the above case fixedly the carrier of small magnet must be to select the material that magnetic is had insulation function on the selection of material, can select copper, aluminium, resin, plastics, rubber etc.

Do transmission with magnetic force induction good pliability is arranged; can not resemble deadly gear, the chain turn round, hard draw; cause parts to damage; stop in emergency in excess load or chance and can also protect parts; magnetic combination mode of the present invention is fully used magnetic force, has finished the effect that adopts the monoblock magnet not finish.This advantageous combination is a lot, and is simple in structure, easy to implement.
