Description
Technical field
The utility model belongs to automobile current generator field, and in particular to a kind of generator stator of vehicle iron of low electromagnetic noise
Core assembling structure.
Background technique
Automobile current generator noise generally comprises electromagnetic noise, mechanical noise and air power noise.Power generator air gap produces
Raw electromagnetic force produces radial magnetic force and tangential magnetic force on stator core, and wherein radial magnetic force is the main next of electromagnetic noise
Source.Currently, stator core axially loaded can be reduced by increasing rubber pad between stator core and front and rear cover, but due to dress
With needs, still there is minim gap between stator core and front and rear cover radial direction, therefore, stator core radial force situation is also
It is not improve, still there is biggish electromagnetic noise.
Utility model content
The purpose of the utility model is to provide a kind of stator iron core of vehicle generator assembling structures of low electromagnetic noise, can delay
The axially loaded and radial force for solving stator core, eliminate the minim gap of stator core radial direction, reduce electromagnetic noise.
The technical scheme adopted by the utility model is
A kind of stator iron core of vehicle generator assembling structure of low electromagnetic noise, including stator core and it is located at stator iron
Core both ends and by being connected with each other two end caps assembling stator core axial compression, it is characterised in that: two end caps it
Between be equipped with rubber pad, one end of rubber pad axial direction passes through inclined-plane and another end with the inner face cooperation of end cap, the other end
The L-shaped end face for making stator core when assembly in one end of the inner face cooperation of lid fitting, rubber pad and end cap is pressed in rubber pad
On, rubber pad stress deformation and stator core is radially being oppressed under the guidance on inclined-plane when assembly.
Further, rubber pad is staggered is arranged between two end caps, and two circumferentially-adjacent rubber pads act on respectively
Stator core both ends and axial direction on the contrary, two end caps are provided with corresponding cross structure according to the arrangement of rubber pad.
Further, cross structure is the boss being distributed on end cap and the inner face of the end cap between boss, boss
End face can be bonded with the inclined-plane on rubber pad, the boss of two end caps is interspersed.
Further, the edge on rubber pad between axial ends in face of stator core side is equipped with groove.
The beneficial effects of the utility model are:
1. axially loaded of the rubber pad in addition to stator core can be alleviated, flexible oblique contract is also corresponded to, rubber when assembly
It pads stress deformation and is radially oppressing stator core under the guidance on inclined-plane, eliminate the minim gap of stator core radial direction, subtract
The radial force for having delayed stator core, reduces electromagnetic noise.
2. staggered two end faces for making stator core of rubber pad are respectively by axial, radial pressure, more
Uniformly, electromagnetic noise is effectively reduced.
3. boss can play the role of protective cover to stator core after two end cap assembly.
4. groove had both been convenient for the deformation of rubber pad, after being filled up completely radial clearance, and can be provided for extra deflection
Space.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the stator iron core of vehicle generator assembling structure of a kind of low electromagnetic noise, including stator iron
Core 2 and two end caps 1 that are being located at 2 both ends of stator core and being assembled 2 axial compression of stator core by interconnection, two
Rubber pad 3 is equipped between a end cap 1, the axial one end of rubber pad 3 passes through oblique with the inner face cooperation of an end cap 1, the other end
Face is bonded with another end cap 1, and one end that the inner face of rubber pad 3 and end cap 1 cooperates is L-shaped so that stator core 2 when assembly
End face be pressed on rubber pad 3,3 stress deformation of rubber pad and radially oppressing stator core 2 under the guidance on inclined-plane when assembly.
Axially loaded of the rubber pad 3 in addition to that can alleviate stator core 2, also corresponds to flexible oblique contract, and 3 stress of rubber pad becomes when assembly
Shape and stator core 2 is radially being oppressed under the guidance on inclined-plane, is eliminating the radial minim gap of stator core 2, it is fixed to slow down
The radial force of sub- iron core 2, reduces electromagnetic noise.
As shown in Figure 1 to Figure 3, in the present embodiment, rubber pad 3 is staggered is arranged between two end caps 1, circumferentially-adjacent
Two rubber pads 3 be respectively acting on stator core 2 both ends and axial direction on the contrary, two end caps 1 according to the row of rubber pad 3
Cloth is provided with corresponding cross structure.Staggered two end faces for making stator core 2 of rubber pad 3 respectively by it is axial,
Radial pressure, it is more uniform, effectively reduce electromagnetic noise.
