Driver shown in Figure 1 comprises a motor 1 and a braking one coupling unit 2.Motor 1 should comprise one of general cylindrical shape stator frame shell 3, and wherein, the stator that comprises a stator winding 4 and a branch of stator lasmination 5 is according to the common mode concentric fits.One rotor 7 also with central longitudinal axis 6 concentric devices.This rotor is fixed on the motor drive shaft 8.Motor drive shaft 8 runs in the bearing of end cap 9,10.A clutch unit is braked away from braking one coupling unit 2(in the position of end cap 10) should cast one with stator frame shell 3.Motor drive shaft should be run on the bearing in the bearing hole 11 by rolling bearing 12, and rolling bearing 12 is the radial-axial ball bearing.13 on ring is held on one of motor drive shaft 8 axle collar 14 within the rolling bearing 12.At another axial vane surface, ring 15 is held in one by 16 of pretension helical compression springs and stops to encircle on 17 outside the rolling bearing 12, ring 17 should be cast one with end cap 10, do not divide a word with a hyphen at the end of a line vertically on motor drive shaft 8 so guarantee rolling bearing 12 on the one hand, can in the slit of spring 16, adjust motor drive shaft 8 vertically on the other hand.
End cap 9 should be cast one with shell 18 outside about cylindrical shape, and by screw 20 by centring pin 19 with the axis 6 concentric stator frame shells 3 that are connected in.Motor drive shaft 8 should be also be held in the bearing hole 21 of this end cap 9 by 22 on the rolling bearing of an axial ball bearing form radially.At this, within the rolling bearing 22 ring 23 also should be resisted against on the axle collar 24 of motor drive shaft 8 and outside the rolling bearing 22 ring 25 should be held on the lock ring 27 by 26 of pretension helical compression springs at the another side face of part 2 (promptly in the face of), 27 of lock rings are fixed in the bearing hole.This ring have with end cap 10 in stop to encircle 17 identical support functions.The function of spring 26 is carried on outside the rolling bearing 22 on the ring 25 applying vertically, the noise that is produced with elimination like this.Then can swing and produce noise as ring outside the rolling bearing not against any thing.The power of spring 26 should be significantly less than the power of spring 16, to avoid offsetting the latter's function.
One dish-shaped flywheel 29 should be fixed on the axle extension 28 of motor drive shaft 8 by tenon groove connecting device 30 with the torsion fixed form, puts rolling bearing 22 on the motor drive shaft 8.The free front end of the shell 31 of dish flywheel 29 should be resisted against and encircle on 23 within the rolling bearing 22, and encircle on 22 in should being pressed on vertically by a nut 33, on the end of thread 32 of nut 33 precession shaft extensions 28, be fixed in the axial direction simultaneously on the position relative with motor drive shaft 8.Comprise rotor 7, motor drive shaft 8 and rolling bearing 12,22 and dish-shaped flywheel 29 in this interior unit so can move along the direction of central longitudinal axis 6, thereby the spring 16 and 26 on moving direction is executed reaction force respectively.
Shell 18 away from the one side of motor 1 by a braking end cap 34(braking frame support bracket) cover the center that end cap 34 should be placed shell 18 by the centering axle collar 35, and thereby be positioned at the position coaxial with axis 6.Braking end cap 34 should be fixed on the suitable flange 37 of one of shell by screw 36.
Should run on the bearing with the driving shaft 38 of central longitudinal axis 6 coaxial positions, one side is in the bearing hole 39 of braking end cap 34 and have the full rotation energy on the other hand in the bearing hole 40 of the dish-shaped flywheel 29 relative with the latter.Driving shaft 38 should also run on the rolling bearing out of the ordinary 41,42 of the radially axial ball bearing shape in the hole 39,40.One coupling, one brake disc 43(clutch, one brake disc) should be fixed on the driving shaft 38 of 41,42 on rolling bearing.This brake disc that is coupled should comprise pivot ring 44 outside the magnetic material.One spring washer 45 should be fixed in that this this is to decide fringe region place outside the ring 44 by screw 47.Spring washer 45 should be within pivot ring 44 be fixed on one of the radially outstanding annular collar 48 of automatic moving axis 38 by screw 47 in the fringe region.This kind uses the fixation of thin spring washer 45 that pivot ring 44 can be moved along the direction of axis 6, and with this axis coaxle.
As coupling surface 49(interface) one of the annular friction pad should adhere to pivot ring 44 in the face of on the one side of dish-shaped flywheel 29.This with the dish-shaped flywheel 29 on opposite on one of corresponding annular coupled surface 50(clutch surfaces) match.Pivot ring 44 should have a ring 51 on its neighboring, extends dish-shaped flywheel 29 vertically.This ring 51 should extend dish-shaped flywheel 29, and having therebetween only is one millimeter one of a few tenths of minimum axial gap a.Dish coupling surface 49(interface) periphery rests against within the ring 51 on the periphery approximately outside.
Braking end cap 34 comprises a coupling coil shell 52(clutch coil shell), shell 52 should surround pivot ring 44, has only one millimeter a few tenths of smallest radial gap b therebetween, and this shell should surround one of the dish-shaped flywheel 29 that connects with coupled surface 50 radial periphery part 54 with radial outside annular outer cover spare 53, also only leaves one millimeter one of a few tenths of radial clearance c therebetween.One annular electro magnetic coupling coil 55(clutch coil) should place the coupling coil shell 52 of the brake end cap 34 of localized immobilization, when these coupling coil 55 excited target, one magnetic circuit 56 passes through outer casing member 53 from coupling line circle shell 52, the ring 51 of the peripheral portions 54 of radial clearance c, dish-shaped flywheel 29, dish-shaped flywheel 29, end play a, pivot ring 44, and radial clearance b and transporting back to coupling line: shell 52, finish closure.Thereby the coupling surface 49 of coupling one brake disc 43 is pressed on the coupled surface 50 of dish-shaped flywheel 29, this then make motor drive shaft 8 and driving shaft 38 couplings.
From Fig. 3 as seen, coupling coil shell 52 should be provided with an axial radial mouth 65 facing in the zone of brake pad 57 in ring 51.The degree of depth of these lower cut 65 extensions should make ring 51 put in this otch 65 about one millimeter along the direction of braking end cap.This otch should be greater than 0.5mm apart from the axial distance that radially reaches in the territory, nearest-neighbour of ring 51, and suitable even greater than 1mm, in addition only roughly radially magnetic circuit can extend through radial clearance b from coupling line circle shell 52.Thereby when avoiding coupling coil 55 excited target the ring 51 " adhesion " of pivot ring 44 on brake end cap 34.
Coupling magnetic circuit 56 should only roughly extend through end play a vertically, and can produce suitable coupling strength at this place.Coupling magnetic circuit 56 also should only roughly extend in the zone of radial clearance c of 53 of shell spares of the peripheral portions 54 of dish-shaped flywheel 29 and coupling coil shell 52 vertically, so can execute displacement force in comprise rotor 7, motor drive shaft 8, and dish-shaped flywheel 29 in interior unit, can make this flywheel resistance spring 16 and 26 and move vertically.This is reached by extra recess.One recess 66 is should be radially outer to extend in the coupling coil shell 52, thereby the peripheral portions 54 of dish-shaped flywheel 29 should put in this recess 66 about 0.5 vertically to 1mm.
Another recess 67 should be arranged in dish-shaped flywheel 29.This limits cylindrical shape limit part 54 on the face that deviates from the brake disc 43 that is coupled.Shell spare 53 should put in this recess 67 vertically.This minimum off normal of 54 pairs of peripheral portions coupling, one brake disc guarantees when coupling coil 55 excited target, and the power to the direction of the restraining coil 43 that is coupled do not executed is on dish-shaped flywheel 29.But the setback force of executing unusual minimum is on dish-shaped flywheel 29.Guarantee so that when coupling coil 55 excited target dish-shaped flywheel 29 does not move to the direction of coupling one brake disc 43.The connection situation of coupling coil 55 and restraining coil 63 should make coupling magnetic circuit 56 and braking magnetic circuit 64b direction in the zone of the coupling coil shell 52 that the two passes through opposite.This causes magnetic flux more to rapidly disappear and the rapider position that moves to from its position on dish-shaped flywheel 29 on the Der Bremssattel 34 of the brake disc that is coupled, and vice versa.As shown in Figure 2, it is 0.1 to 0.2mm wide that the air-gap 68 that coupling surface 49 and coupled surface are 50 should be about, promptly be converted to coupling and be converted to when braking when self-retention, have braking gradually 57 and the pivot ring 44 of the coupling surface 49 very pathway of weak point of in two situations, only need dividing a word with a hyphen at the end of a line from coupling.The air-gap 68 that brake pad 57 that Fig. 3 is presented in being presented at during the coupling with bigger engineer's scale and brake area are 58.
Being held within the rolling bearing 41 in the dog point lid ring 69 should be held in one of driving shaft 38 and stopping on the axle collar 70 in the face of on the face of dish-shaped flywheel 29.Should the adjusting on the cap 72 being resisted against one towards outer face of ring 71 outside this rolling bearing 41, this nut precession are outside around the bearing hole 39 of braking end cap 34 on the screw thread 73.This adjustment nut 72 should be fixed on the position relevant with braking end cap 34 by dog screw 74.The position of this driving shaft 38 is fixed by the bearing of adjusting nut 72 and above-mentioned rolling bearing 41 when self-retention one coupling unit 2 moves.
In ring 75(prop up within the rolling bearing 42 that is held in the dish-shaped flywheel 29 encircle 75) the face in the face of coupling one brake disc 43 should be resisted against and one of fix on the driving shaft 38 on the stop member 76, this stop member is made of lock ring.The face in the face of motor of interior ring 75 is free and open.
The face in the face of coupling one brake disc 43 of ring 77 is free and open outside the rolling bearing 42.The face in the face of motor 1 of outer shroud 77 should be resisted against one and keep on the sleeve 78, and this sleeve places bearing hole 40.This keeps sleeve should have a slot 79, is put in this slot by one of one of the fixing guard plate 81 of nut 33 tenon 80, so maintenance sleeve 78 fixedly is being pressed on the torsion on the dish-shaped flywheel 79.The hole 82, one that driving shaft 38 should have a binding is adjusted screws 83 and can be pierced into this hole by bottle opener or similar tool and adjusted, in the screwed hole 84 of this screw precession shaft extension 28.So rotate when adjusting screw 83 and can adjust the axial location of this screw, or clearly say it, adjust be fixed thereon diametrically outstanding stop the axle collar 85 and motor drive shaft 8 and thereby with the position of dish-shaped flywheel 29 relations.Place one of some bi-metal plates 86 of adjusting on the screw 83 to prop up to be held in this and stop on the axle collar 85.(bi-metal plate of promptly the most approaching coupling one disc brake 43 should prop up on the ring edge 87 that is held in maintainance set tube 78 relative bi-metal plate.Dish flywheel 29 and driving shaft 38 relevant axial locations change it by adjusting screw 83 precessions or a back-out extension 28.Because motor drive shaft 8 and dish-shaped flywheel 29 are constantly pushed by the direction of compression spring 16 to coupling one brake disc 43, so coupling one brake disc 43 and brake pad 57 press on stopping pressure and can adjust the air-gap 68 of 50 of coupling surface 49 and coupled surfaces simultaneously by 72 adjustment of adjustment nut in the braking district 58 of braking end cap 34.When coupling coil 55 and restraining coil 63 all not during excited target, the brake disc 43 that is coupled should press on the brake area 58 of braking end cap 34 with initial pressure, and this pressure can be adjusted as described.When expanding owing to the thermic load of height conversion as coupling surface 49 and brake pad 57, this also causes dish-shaped flywheel 29 correspondences to be heated.This heat conducts to bi-metal plate 86, makes its bending, presses mutually so each bi-metal plate is arranged mutual bending according to it.This causes adjusting screw 83, and the direction to motor 1 moves together with the power of motor drive shaft 8 and dish-shaped flywheel 29 resistance springs 16.So compensation is owing to the expansion that the heat of coupling surface and brake pad 57 causes causes reducing of air-gap 68.It is essential that this kind is compensated for as institute because air-gap 68 only 0.1mm is wide usually, and when connect being coupled a brake disc 43, prevent bulk noise.Yet, during operation in, this little air-gap should accurately be kept, and does not allow to reduce.
As being shown in Fig. 1 especially, cooling fin 98 should be fixed on the stator frame shell 3.These fins should be distributed on the zone of stator frame shell, extend radially and extend in parallel with axis 6.Surround the cup-shaped housing 99 suitable pushing covers of one of cooling fin 98 on whole stator frame shell 3.The panel 100 of housing 99 should place on the spacer 101, and each spacer should be cast one with end cap 10.Housing 99 should be fixed on the spacer 101 by screw 102.The panel 100 of housing 99 should have hole 103, enters for cold air.The general cylindrical shape case 104 of housing 99 should place on the protuberance 105 of cooling fin 98, contacts so only make sticking shape with housing 99.So only minimum heat is passed through cooling fin 98 and the housing 99 that arrives from 3 conduction of stator frame shell, housing 99 only is subjected to minimum heat.
The cooling fin 106 suitable with cooling fin 98 also should place shell 18.These fins should radially partly extend between end cap 9 and the shell 18, because of it supports this end cap simultaneously.29 on end cap 9 and dish-shaped flywheel should have a free space 107, be formed at 104 of the cases of fin 98 and stator frame shell 3 or housing 99 or cooling fin 106, end cap 9, and this space of 18 on shell in cooling duct 108 be connected.
Should there be a suction district 109 in dish-shaped flywheel 29, to face on the one side of motor 1.This suction district is preferably the shape of annular space, and opening passes to free space 107, the shell 31 of this space encloses dish flywheel 29.Radial passage suction district 109 since then stretches out.The fin 111 of extension limits these passages by axially reaching radially, and each fin should be cast one with dish-shaped flywheel.The air lead ring 112 of one annular should be fixed on the one side of dish-shaped flywheel 29 of deviating from of fin by screw 113.This ring defines the radial passage 110 that extends to motor 1.So the fan of formation is axial one hair-dryer radially.
The cooling air that is drawn through opening flows through cooling duct 108 according to flow direction arrows 114, flows through free space 107, suction district 109, and flow through radial passage 110.As shown in Figure 1, because suction district 109 extends to the vicinity of coupled surface 50, so especially effectively cool off the important area of coupled surface 50.
Air flows out from the radial passage 110 of cooling off 115 of fins, and these fin body plans are on periphery and front side outside the braking end cap 34.One annular slab crown cap 117 should be fixed in outside the braking end cap 34 on the front surface by screw 116, and flows in the air some of 115 of fins according to arrow 118 and to be subjected to radially inside stream of guiding, and surface before the cooling braking end cap.At the brake area 58 of braking end cap 34 contiguous and coupling coil 55 and restraining coil 63 radially between, this braking end cap 34 should have an annular notch, as spin chamber, this chamber extend into coupling coil 55, restraining coil 63, and brake area 58 be close to.Air in this chamber along the direction eddy flow of arrow 118.Air is discharged by the outlet 120 of one of adjusting near the sheetmetals lid 117 the nut 72 the radially inner side position then.
Radially the cooling air that sends from radial passage 110 of overline guiding becomes the air flow stream parallel with axis 6 and should carry out in reboot district 121 in 115 of cooling fins, is limited by shell 18 outside this boot section.
Though the suitable configuration that is considered as the present invention at present has been described, still has been understandable that wherein and can does various changes and modification, and do not break away from the present invention, so its purpose is in all these changes and modifications of spirit that contains the present invention and scope.
