Embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
For ensureing that speed reducer uninterruptedly normally runs, for speed reducer is equipped with main driving and driving twin-stage drive system for subsequent use, as shown in Figure 1.
Composition graphs 2, main drive system comprises permanent magnet clutch A, energized magnetic clutch B, support C, main motor D etc., permanent magnet clutch A is fixed on base plate 5 by support C, permanent magnet clutch A drive end connects main motor D, permanent magnet clutch A driven end connects energized magnetic clutch B one end, and the energized magnetic clutch B the other end connects speed reducer M master and enters axle.
Composition graphs 3, drive system for subsequent use comprises limited-moment permanent magnetic coupling E and spare motor F, and permanent magnetic coupling E drive end connects spare motor F, and permanent magnetic coupling E driven end connects speed reducer M pair and enters axle.
Permanent magnet clutch A adopts non-limit to turn round type permanent magnet clutch, comprises rotating disk, and rotating disk two ends are respectively equipped with drive end axle sleeve and driven end axis body; Be made up of the permanent magnet that two rows are mutually corresponding in rotating disk, leave air gap, belong to untouchable connection between two row's permanent magnets, two row's permanent magnets connect drive end axle sleeve and driven end axis body respectively.When drive end rotates, corresponding sports between two row's permanent magnets, permanent magnet cutting magnetic line, produce eddy current in the conductor, eddy current and then generation dislike magnetic field, the magnetic field interaction effect produced with permanent magnet, there is the time difference in driven end transmission, thus the impact to load during buffering motor start-up, and the rotating speed realized between the two and moment of torsion transmission.
Energized magnetic clutch B comprises Moving plate 3 and the armature 2 of coaxial setting, Moving plate 3 connects permanent magnet clutch A driven end axis body, and armature 2 is an axle dress rotating disk simultaneously, connects speed reducer and enters axle, between Moving plate 3 and armature 2, spring sheet is housed, the shell of Moving plate 3 is also fixed with electromagnetic coil 1.Lighting outlet 4 connects electromagnetic coil 1, and for accessing power supply to electromagnetic coil 1, lighting outlet 4 is taked without slip ring design.
In normal state, after switching on power, electric current is inputted by lighting outlet 4 main drive system, and electromagnetic coil 1 is worked, and produce magnetic force, adsorb armature 2 through Moving plate 3, armature and Moving plate are combined closely.Drive permanent magnet clutch A to rotate during motor D transmission, and then drive Moving plate 3 and armature 2 to rotate, transmit its torque by Moving plate 3 and motor synchronous, and drive the speed reducer be connected with armature 2 to enter axle, speed reducer is operated.Due to permanent magnet characteristic, during transfer, there is the slippage of a short time, the sluggish transfer of energized magnetic clutch and speed reducer, thus serve buffer function.
When main drive system fault state or parts need dismounting, lighting outlet 4 deenergization, electromagnetic coil 1 dead electricity, magnetic force disappears, inner armature 2 is flicked by spring sheet, throws off the combination with Moving plate 3, driven end is separated with drive end, thus the rotating speed interrupted from motor and moment of torsion transmission, be convenient to the maintenance of transmission part, replacing.
Limited-moment permanent magnetic coupling E comprises rotating disk, and rotating disk both sides are respectively equipped with live axle and driven shaft, and live axle connects spare motor F, and driven shaft connects speed reducer M pair and enters axle.In rotating disk, two ends are respectively furnished with copper ring 6 and the p-m rotor 7 of one group of mutual corresponding setting, and copper ring 6 is positioned at inside p-m rotor 7, leaves air gap 8 between copper ring 6 and p-m rotor 7, belongs to untouchable connection, and two groups of p-m rotors 7 connect live axle and driven shaft respectively.
When spare motor F rotates, between the copper ring 6 at two ends and p-m rotor 7, because of cutting magnetic line, and produce foucault current, and dislike magnetic field, owing to there is the time difference in both transmission, thus the impact during startup of buffering spare motor, and realize moment of torsion transmission between the two.And during driven end operation, as excessive in load, foucault current can change, generation is repelled by copper ring 6 pairs of p-m rotors 7, passes p-m rotor 7, and expand air gap 8, p-m rotor 7 reduces by the quantity of magnetism, and its rotation will slow down or interrupt, thus protection transmission device.
When the speed reducer permanent magnet coupling that the utility model provides and energized electromagnetic clutch dual drive system use, under speed reducer normal working, main drive system work, drive system for subsequent use does not work.When main drive system breaks down, electric controller is switched to drive system work for subsequent use immediately, to ensure that speed reducer continues to run well, meanwhile, changes trouble unit in time.
When the utility model assembly of devices is installed, can ensure that the centering of permanent magnet clutch A and energized magnetic clutch B is accurate, avoid tradition at the scene permanent magnet clutch and magnetic clutch separately and speed reducer connection time, usually there is the problem of deviation, so that affect speed reducer and normally work.
The utility model can avoid the original hydraulic couplers of use and the defect of single use permanent magnet clutch.When speed reducer runs, as the motor that drives or permanent magnet clutch break down, this device can disconnect original connection, also can automatically switch to drive system for subsequent use under automatically controlled condition, to ensure that speed reducer continues to run well, simultaneously can change trouble unit in time.
Permanent magnet clutch and the energized magnetic clutch of the main drive system of the utility model combine as a whole assembly, but its permanent magnet clutch and energized clutch connect that to use be its essential characteristics.This compound mode, had both embodied permanent magnet clutch buffer function, embodied again the controlled effect of clutch of magnetic clutch.This device really achieves and generator set can be keeped in repair and change the motor of fault, permanent magnet clutch, energized magnetic clutch when not stopping generating.
The utility model can use on the motor of more than 30KW relatively high power, drives gearwheel at speed reducer, when driving shroud, upgrades to the reliability of original speed reducer running state and Security, and the research and development having filled up related domain are blank.
