Description
Technical field
The utility model relates to a kind of speed-regulating type magnetic coupler, particularly a kind of explosion-proof type magnetic coupling by rack-and-pinion adjustment air gap.
Background technology
Magnetic coupling is primarily of copper rotor, p-m rotor and controller three part composition.Generally, copper rotor is connected with motor shaft, and p-m rotor is connected with the axle of working machine, has air gap (being called air gap), do not have the mechanical connection of transmitting torque between copper rotor and p-m rotor.Like this, define soft (magnetic) between motor and working machine and connect, by the change regulating air gap to realize working crankshaft moment of torsion, rotating speed.Because of the difference of air gap regulative mode, permanent magnetic vortex drive device is divided into standard type, delaying type, distance-limiting type, speed-regulating type etc. dissimilar.Traditional speed-regulating type magnetic coupler adopts open design, because copper dish can produce vortex flow when cutting the magnetic field that permanent magnet produces, if when therefore the magnetic coupling of this open by design is applied in the environment containing flammable explosive gas, there is great potential safety hazard; Simultaneously traditional magnetic coupling is when carrying out the adjustment of air gap, require that two p-m rotors can do the motion that direction is contrary, movement velocity is identical, motion amplitude is identical, conventional magnetic coupler then cannot meet above-mentioned requirements completely for the mechanism adjusting air gap, often there is the situation that movement velocity is inconsistent or motion amplitude is inconsistent.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, can to carry out work in containing the environment of flammable explosive gas, and utilize the magnetic coupling of pinion and rack adjustment air gap.
Technical solution of the present utility model is: a kind of explosion-proof type magnetic coupling by rack-and-pinion adjustment air gap, comprise chassis 1, chassis 1 is provided with the output shaft 3 of output support 2 rotational support, output support 2 is provided with electric operator 4, electric operator 4 is connected with the speed adjusting gear 5 be arranged on outside output shaft 3, speed adjusting gear 5 can drive copper dish 6 in the axially motion of output shaft 3, it is characterized in that: what match with described copper dish 6 is provided with the first permanent magnet 7 and the second permanent magnet 8, and the first permanent magnet 7 and the second permanent magnet 8 are all connected on power shaft 9, and the first permanent magnet 7 and the second permanent magnet 8 are all positioned at annular seal space 10, described annular seal space 10 is by the first steel disk 11, second steel disk 12 and cylinder 13 are interconnected composition, first permanent magnet 7 together can move with copper dish 6, first permanent magnet 7 is provided with the first tooth bar 14, telophragma 15 is provided with between the first permanent magnet 7 and the second permanent magnet 8, telophragma 15 is provided with the gear 16 that can rotate, second permanent magnet 7 is provided with second tooth bar 17 identical with the first tooth bar 14, gear 16 engages mutually with the first tooth bar 14 and the second tooth bar 17.
Compared with the existing technology, tool has the following advantages the utility model:
The explosion-proof type magnetic coupling by rack-and-pinion adjustment air gap of this kind of version, its structure is simple, designs ingenious, rationally distributed.The copper dish of traditional magnetic coupling and permanent magnet are open by design, space residing for it is directly connected with external environment, such copper dish can produce vortex flow when cutting the magnetic field that permanent magnet produces, if and containing flammable explosive gas in the environment at now magnetic coupling place, then there is larger potential safety hazard.In order to solve the problem, copper dish and permanent magnet are sealed among annular seal space by the magnetic coupling of the application, allow itself and external environment completely cut off, and have so just fundamentally stopped the potential safety hazard produced because there is flammable explosive gas in operational environment; It utilizes a gear and two identical tooth bars engaged with it to coordinate simultaneously, action while realizing two permanent magnets, ensures the consistency of permanent magnet motion.The manufacture craft of this magnetic coupling is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of explosion-proof type magnetic coupling by rack-and-pinion adjustment air gap, comprise the chassis 1 based on, chassis 1 is provided with the output shaft 3 of output support 2 rotational support, output support 2 is then provided with electric operator 4, electric operator 4 is connected with the speed adjusting gear 5 be arranged on outside output shaft 3, speed adjusting gear 5 can drive copper dish 6 in the axially motion of output shaft 3, what match with copper dish 6 is provided with the first permanent magnet 7 and the second permanent magnet 8, and the first described permanent magnet 7 and the second permanent magnet 8 are all connected on power shaft 9, first permanent magnet 7 and the second permanent magnet 8 are all positioned among annular seal space 10 simultaneously, described annular seal space 10 is then by the first steel disk 11, second steel disk 12 surrounds with the cylinder 13 be connected between which and forms, the first above-mentioned permanent magnet 7 together can move with copper dish 6, and on the first permanent magnet 7, be provided with the first tooth bar 14, telophragma 15 is provided with between the first permanent magnet 7 and the second permanent magnet 8, what this telophragma 15 then rotated is provided with gear 16, second permanent magnet 8 is provided with second tooth bar 17 identical with the first tooth bar 14, and gear 16 and the first tooth bar 14, second tooth bar 17 engages mutually.
The course of work of the explosion-proof type magnetic coupling by rack-and-pinion adjustment air gap of the utility model embodiment is as follows: when needing the adjustment carrying out air gap, electric operator 4 drives copper dish 6 to axially move relative to output shaft 3, because copper dish 6 is connected with the first permanent magnet 7, therefore the first permanent magnet 7 also can axially move relative to output shaft 3, when the first permanent magnet 7 moves, the first tooth bar 14 on it can rotate by driven wheel 16, and the second tooth bar 17 be meshed with gear 16 equally also can move, and then drive the second permanent magnet 8 to move, because the first tooth bar 14 is identical with the second tooth bar 17, therefore to do direction contrary for the first permanent magnet 7 and the second permanent magnet 8, speed is identical, the relative motion that amplitude is identical, and then realize the object of two permanent magnets synchronous change air gap simultaneously,
And due in the process of this kind of magnetic coupling work, the output precision be made up of permanent magnet and copper dish completely wrap up by annular seal space 10, even if therefore copper dish creates vortex flow when cutting the magnetic field that permanent magnet produces, also can not impact by environment to external world, therefore this kind of magnetic coupling is suitable for working in the environment with flammable explosive gas.
