Abstract
A kind of new non-contact type magnetic force Hooks coupling universal coupling, the transmission device for being used for two between centers and transmitting moment of torsion that a kind of general principle with magnetics designs.Its basic structural feature is the circular flat board made for non-magnet material, and in the in-plane of circular flat board, circumferentially drilling equidistant at certain intervals, drilling hole amount are necessary for even number.Inlay circular magnet piece in circular hole, the polarity of flat thin magnet is that N poles, S poles positive and negative alternate are inlayed.Separately in the middle mounting sleeve of circular flat board, to be separately mounted to the shaft end of driving shaft and driven shaft.The principle of its Main Basis of utility model is：Repel each other and the magnetic line of force has longitudinal stretch-proof and laterally incompressible characteristic with attracting between permanent magnet intrinsic magneticaction and permanent magnet, what principle designed and produced.It is non-maintaining that there is long service life without any Mechanical Contact between driving shaft and driven shaft, thus without abrasion.
Description
Technical field
A kind of two axles (driving shaft and driven shaft) for being used for coupling different plant equipment are the utility model is related to, are allowed to altogether
It is same to rotate to transmit the Novel transmission coupling arrangement of moment of torsion.
Background technology
The existing various shaft couplings for being used to be driven, such as diaphragm coupling, gear coupling, plum coupling, sliding block connection
Axle device, Hooks coupling universal coupling, yielding coupling, Falk flexible coupling, bellows coupling etc..There is rigid attachment not allow two
The shaft coupling of axle relative displacement, also flexible connection, available buffer absorbing, compensate axial displacement, the shaft coupling of micro radial displacement
Etc., various structures, model is various.
Above-mentioned all shaft couplings, although type structure is different, its most important feature is：Shaft coupling and driving shaft,
Directly contact is fixedly connected between driven shaft.Such connecting mode, it can be limited because of the various conditions installed and used
System, such as cased muff coupling, the ability moved without two coupled axis malalignments of compensation, also without buffering absorbing
Performance, so can only be relatively steady in load rotating speed, and by two axles of connection it is relative offset it is minimum in the case of just can be selected, and install
Centering inconvenience.And for example Hooks coupling universal coupling, though there is angular compensatory amount larger, two axles can be made axis angle to be present in not same axis
In the case of realize continuously running for two axles, but its same performance without buffering absorbing.Secondly can be because of mechanical oscillation, material
Intensity, manufacturing process, lubricate, abrasion, overload etc. the restriction of various factors and influence normal use.
The content of the invention
The defects of the utility model installs and uses aspect for existing various shaft couplings, there is provided a kind of driving shaft and driven shaft
Between there is no Mechanical Contact, thus be not required to lubricate without abrasion, long-term use of new shaft coupling that is non-maintaining, and being broadly applicable
Device.
The utility model solves the technical scheme that its technical problem uses,
A kind of no Mechanical Contact, with the non-contact type magnetic force Hooks coupling universal coupling of magnetic drives, its key structural feature is：
With non-magnet material aluminium alloy or copper as made of design size circular slab；In in-plane circumferentially certain of circular flat board
Drilling at equidistant intervals, reserved magnitude of interference during drilling, to ensure that the flat thin magnet inlayed will not fall off；The quantity in hole is necessary for even
Number；Circular magnet piece is inlaid into circular hole with static pressure, the extremely positive and negative identical mounted in pairs of the polarity of circular magnet piece, i.e. N.S；
A hole is opened in the centre of plectane, is equally press-fitted into circular magnet piece；This flat thin magnet is keeping and balance another phase therewith
Circular flat board spacing distance；The mounting sleeve among plectane simultaneously, to couple driving shaft or driven shaft；Pass through increasing
The quantity of few flat thin magnet that adds deduct or the size thickness of adjustment flat thin magnet, so as to adjust the size of driving force.
The utility model aluminium alloy or copper or other non-magnet materials) by design size making circular discs, in disk
In-plane circumferentially equidistant drilling (reserves the magnitude of interference, drilling hole amount is necessary for even number at regular intervals during drilling.Institute
Center of circular hole is bored to be press-fitted into circular magnet piece with static pressure method.The polarity of circular magnet piece is that S.N poles are alternately inlayed.Disc centre
Equally inlay circular magnet piece.The flat thin magnet polarity of disc centre is mounted opposite to keep appropriate gap between two disks, in addition
The intermediate fabrication fixed hub of circular discs, so as to installed in the shaft end of line shaft or driven shaft.
The principle of the utility model foundation is：Repel each other with attracting between permanent magnet intrinsic magneticaction and permanent magnet, with
And longitudinal stretch-proof, horizontal incompressible inherent characteristic.Principle and design and produce.Select from magnetics basis and magnetic material, section
Learn the core drive that the basic research of net one is innovation.
It is of the present utility model to be structurally characterized in that, without any Mechanical Contact between driving shaft and driven shaft, therefore without abrasion, nothing
Noise, it is convenient for installation and maintenance without lubrication.According to service load classification, the volume size and quantity of magnet are adjusted, is designed and produced
The disk of different size model numbers, to adapt to different driving torques.
The beneficial effects of the utility model are to be generally applicable to a variety of transmission mechanisms, are particularly suitable for universal transmission mechanism.
Do not influenceed by bad border factor and use condition limits, there is flexible start-up characteristic to adapt to the work such as high/low temperature, humidity, airborne dust
Condition.Effective vibration isolation, long service life.
The utility model is further illustrated with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model.Each reference implication is as follows in figure：
1. the magnetic line of force between the roundlet flat thin magnet of 4. axle sleeve of aluminium alloy disk 2. roundlet flat thin magnet, 3. great circle flat thin magnet 5.
The magnetic line of force is distributed magnetic line of force distribution between 6. middle great circle flat thin magnets between being distributed 7. roundlet flat thin magnets.
Embodiment
As shown in figure 1, roundlet flat thin magnet 2 is equally spaced some right in figure, alternating polarity is inlayed.Among aluminium alloy disk 1
The polarity opposing insert of great circle flat thin magnet 3.Its structural principle is：Repel each other using between permanent magnet to suction, and longitudinal stretch-proof,
Laterally incompressible synthesis magnetic force is realized.In figure.Produced between some flat thin magnets to roundlet that alternating polarity is inlayed attracting
Power, the magnetic line of force in its magnetic field is parallel distribution.Under inactive state, the roundlet flat thin magnet inlayed on two relative disks is protected
Attracting situation is held, and the great circle flat thin magnet polarity at center produces the power repelled each other relatively, for balancing suction between small magnet piece,
It is former between the roundlet flat thin magnet on roundlet flat thin magnet and another disk inlayed on disk when one disk rotational of any of which
The magnetic line of force for carrying out parallel distribution produces distortion, and has the inherent characteristic of anti-transverse compression between the attracting permanent magnet of polarity, that is, having makes
The magnetic line of force voluntarily recovers parallel characteristic, therefore, when any of which disk rotational, that is, drives turning for another disk on the other side
It is dynamic, realize contactless transmission.
