Description
Technical field
Technical field of motors is the utility model is related to, particularly a kind of motor with cup rotor of convenient adjustment diastema.
Background technology
In the prior art, motor with cup rotor is typically to be made up of fore-stock, stator, rotor, after-poppet and thrust washer, rotor
Through stator inner hole, front and back ends are inserted in forward and backward support respectively, and rotor is secured between thrust washer and after-poppet.Motor leads to
After electricity, rotor will rotate.Because in the fabrication process, all there is certain tolerance in each parts, such as：Stator thickness ±
0.5, rotor thickness ± 0.5, forward and backward support height each ± 0.1, thrust washer height tolerance ± 0.1, cumulative limit is exactly ±
1.2mm, and the diastema of most of motor with cup rotor is (i.e.：Gap) require it is 0.2-1.0mm.When the gap of rotor in the axial direction
(i.e.：Diastema) it is excessive when, its be powered operating when, the forward and backward play of rotor assembly is severe, neither can guarantee that what is loaded on rotor assembly
Position, bigger noise can be produced again.And when gap is too small, occur that rotor assembly is stuck between forward and backward support again,
Motor is caused to operate, or the frictional force between rotor assembly and forward and backward support increases, and so as to influence electrical machinery life, and increases
Big noise.Reality batch production process in, it is impossible to every motor by adjust the height of thrust washer at leisure come
Reach suitable axial gap, the station for detecting the gap can only be set up, and set up defective work and repair post, so as to add
Cost of manufacture.
Chinese patent (number of patent application 201280023407.5) is disclosed " thrust washer for being used for motor ", described to stop
Pushing pad piece be arranged on axle (16) bearing (18) and rotor (14), preferably described rotor (14) by brush (38) loading,
Between the electrical contact element (24) and/or friction plate group (36) of rotation, wherein the thrust washer (28) has with two ends
Side (32,34), region for sealing, and exist on each side (32,34) and at least one to be used for the bearing
(18) or the radial direction of the rotor (14) the section that reclines (50,52).It is characterised by by the thrust washer (28) of the present invention, its
It is made up of at least one stiffening members (54) and soft component (56), wherein the section that reclines (50,52) of the radial direction recline
Part on the rotor (14) and/or bearing (18) is formed by the soft component (56).
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of convenient adjustment diastema, it is possible to increase product qualification rate
With the motor with cup rotor of production efficiency.
To achieve the above object, technical solution adopted in the utility model is a kind of split-pole of convenient adjustment diastema of design
Motor：Including fore-stock 1, stator 2, rotor 3 and thrust washer 4, the rotor 3 is installed in stator 2, fore-stock 1 and rear branch
Frame 5 is separately mounted to the forward and backward both ends of stator 2, and thrust washer 4 is arranged between stator 2 and after-poppet 5；The thrust washer 4
It is to be made up of pedestal 4-3, compressible cylinder 4-2 and carrying cylinder 4-1, the compressible cylinder 4-2 is arranged on pedestal 4-3, carrying cylinder
4-1 is arranged on compressible cylinder 4-2.
Described carrying cylinder 4-1 is conically shaped.
The motor with cup rotor of convenient adjustment diastema of the present utility model, as a result of by three sections of thrust washers formed, profit
Can be preferable with the extrudability of the compressible cylinder of thin-wall circular tubular the characteristics of, thrust washer easily can be expressed to some
The arbitrary height of scope, so as to have the function that to eliminate the cumulative limit of each parts, ensure rotor between forward and backward support
Axial diastema.Thus, the adjustment of its diastema is more convenient, and the qualification rate of product is also higher.Further, since diastema adjustment compared with
It hurry up and the qualification rate of product be higher, therefore its production efficiency is also improved.
Brief description of the drawings
Fig. 1 is main cross-sectional schematic diagram of the present utility model；
Fig. 2 is axonometric exploded view of the present utility model；
Fig. 3 is the main section view enlarged diagram of thrust washer of the present utility model.
In figure：
1 is fore-stock, and 2 be stator, and 3 be rotor, and 4 be thrust washer, and 5 be after-poppet, and 4-1 is carrying cylinder, and 4-2 is to press
Contracting cylinder, 4-3 are pedestals.
Embodiment
Below in conjunction with drawings and examples, the utility model is further described.Following explanation is to use to enumerate
Mode, but the scope of protection of the utility model should not be limited to this.
The motor with cup rotor of the convenient adjustment diastema of the present embodiment be by fore-stock 1, stator 2, rotor 3 and thrust washer 4 with
And after-poppet 5 is formed.
Thrust washer 4 is made up of tri- sections of pedestal 4-3, compressible cylinder 4-2 and carrying cylinder 4-1, and pedestal 4-3 is shim liner
Shape, centre are provided with the through hole for installing armature spindle；Compressible cylinder 4-2 is extrudability energy preferably thin-wall circular tubular, is set
On pedestal 4-3；Carrying cylinder 4-1 is thin-walled conical tube, is arranged on compressible cylinder 4-2.Thrust washer 4 is by copper sheet material
Disposably it is process.
Rotor 3 is installed in the hole of stator 2, and fore-stock 1 is first on the front end of stator 2, the armature spindle of the rear end of rotor 3
Thrust washer 4 is worn, then after-poppet 5 is installed again.
Its specific mounting and adjusting is as follows：
First the bottom surface of stator 2 is fixed in frock, then rotor 3 is passed through to the hole of stator 2, before being positioned at frock simulation
On support 1, then, double pressure head cylinders of institute's band are descending in frock, and one of pressure head is past the thrust washer 4 on rotor 3
Push, another pressure head stops that cylinder is descending, and now, thrust washer 4 is compressed to suitably immediately after being contacted with the top surface of stator 2
Highly (mainly can be preferable using the compressible cylinder 4-2 possesseds extrudability of thin-wall circular tubular the characteristics of, compressible cylinder 4-
2 after stress is compressed, so as to be fastened on the axle of rotor 3), thereafter, after-poppet 5 coordinates through rotor 3 with stator 2, by solid
Determine screw to lock after-poppet 5, stator 2, fore-stock 1, assembling is completed.
The motor with cup rotor of convenient adjustment diastema of the present utility model, is no different, its thrust using upper with simple shaded pole motor
Packing ring both can be applied to motor with cup rotor, can also expand applied on other kinds of motor, have same use function.
