Accompanying drawing explanation
The speed reducer coupling fluid-structure that Fig. 1 provides for the present embodiment and energized electromagnetic clutch dual drive system structural representation;
Fig. 2 is main driving system structure schematic diagram;
Fig. 3 is driving system structure schematic diagram for subsequent use.
Embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Because hydraulic couplers uses widely, thermal power plant cannot all be replaced at short notice.But the safety and reliability that must as much as possible improve when speed reducer runs, therefore be equipped with main driving and driving twin-stage drive system for subsequent use for speed reducer, as shown in Figure 1.A drive end installs coupling fluid-structure drive system, and another drive end installs energized electromagnetic clutch drive system, just can when hydraulic couplers drives inefficacy, and immediately switch, the equipment that ensures continues normal operation.Energized electromagnetic clutch drive system can also to be equipped with as main driving, and using original hydraulic couplers drive system as standby system, the drawback that when avoiding hydraulic couplers long-time running, fault is multiple.
Composition graphs 2, main drive system comprises hydraulic couplers E and main motor F, and hydraulic couplers E drive end connects main motor F, and hydraulic couplers E driven end connects speed reducer M master and enters axle.
Hydraulic couplers E is airtight chamber, includes pump impeller 6 and turbine 9.Airtight chamber inside is full of fluid, and oil circulation can be made to flow.Pump impeller 6 is connected with main motor F by input axle sleeve 7, and turbine 9 is connected with speed reducer M by output sleeve 8.When main motor F operates, centrifugal pump impeller 6 operates thereupon, fluid in work chamber is thrown out of, after this high speed fluid enters turbine, the turbine 9 promoting opposite side rotates, drive speed reducer M to rotate by output sleeve 8 after turbine 9 rotates, the energy obtained from pump impeller is passed to output shaft and speed reducer by worm gear.Final liquid returns pump impeller, forms the flowing gone round and begun again.
In normal state, main motor F's main drive system operates, hydraulic couplers E pump impeller end by be connected with main motor F enter axle drive, pump impeller rotates thereupon.Pump impeller and worm gear, be installed in one and be full of fluid and in the airtight work chamber of flowing capable of circulation.Pump impeller and worm gear fill respectively by axle, are connected with drive motor and load end.During motor rotation, drive pump impeller to stir fluid, oil pressure promotes worm gear and rotates, and by fluid as medium, and sluggish worm gear wheel, and then the impact to load when reducing electric motor starting.
Composition graphs 3, drive system for subsequent use comprises non-limited-moment permanent magnetic coupling A and spare motor D, permanent magnetic coupling A drive end connects spare motor D, and permanent magnetic coupling A driven end connects energized magnetic clutch B one end, and the energized magnetic clutch B the other end connects speed reducer M pair and enters axle.Permanent magnet clutch A is fixed on base plate 5 by support C.
Permanent magnetic coupling 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.
When the speed reducer coupling fluid-structure 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.
When the utility model assembly of devices is installed, can ensure that the centering of permanent magnetic coupling A and energized magnetic clutch B is accurate, avoid tradition at the scene permanent magnetic coupling 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 defect of the hydraulic couplers be originally used alone, and to eliminate because hydraulic couplers fault is multiple, and must affect the worry that generator set normally runs.By improving the equipment reliability of standby system, ensureing that standby system switches immediately when hydraulic couplers goes wrong, generator set being run uninterrupted.When finding faults itself under drive system idle state for subsequent use, standby system originally can because associate with the coaxial of main system, and the corresponding running of meeting, cannot shut down and solve fault separately.The present embodiment permanent magnetic coupling and energized magnetic clutch combine, can not affect under speed reducer normal operation, and throw off in time and be connected with coaxial, change trouble unit, make that drive system for subsequent use is in well at any time, upstate, and main system can be replaced over a long time run.
Permanent magnetic coupling and the energized magnetic clutch of the utility model drive system for subsequent use combine as a whole assembly, but its permanent magnetic coupling and energized clutch connect that to use be its essential characteristics.This compound mode, had both embodied permanent magnetic coupling 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 magnetic coupling, 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.
