Description
Technical field
This utility model relates to motor, particularly to a kind of electric machine casing based on hot cover process and stator connection structure and
Electric machine casing.
Background technology
Automobile drive motor also differs according to different principle, structure.Wherein permagnetic synchronous motor is automobile drive motor
Middle range of application is the widest, the motor type that usage quantity is most.Stator silicon steel sheet and the connection side of housing in permagnetic synchronous motor
Method, traditional handicraft is the mode of hot jacket, i.e. heated shell so that housing size after being heated deforms, and is formed with stator
Matched in clearance, along with the decline of temperature, matched in clearance becomes interference fit, so that housing is enclosed within stator core firmly
On outer wall.
In the hot jacket structure that great majority use at present, housing is as it is shown in figure 1, inner walls is bright finish, and housing has evaporative pattern
Casting, also has aluminium alloy extruded maturation process support of Denging.Stator, as in figure 2 it is shown, stator core outer wall is bright finish, has a little technique
Feature.Hot jacket crosses Cheng Qian, and housing needs to be placed on and is incubated in high-temperature cabinet to 180～200 DEG C so that housing inner circle size is amplified.?
After housing heating, being enclosed within immediately on stator core, stator core is inserted in housing, and stator core outer wall connects with inner walls
Touch, after housing cools down, form interference fit, complete the process of hot jacket assembling；During stator heating jacket, stator core needs and housing
Angled.As it is shown on figure 3, during complete machine uses, interference power has presented housing 2 and the fixing of stator core 1 and moment of torsion
Transmission.
Although the design feature of this kind of design inner walls is simple, but bright finish needs cylindricity the highest.In processing essence
Degree is unable to reach when requiring, is easily caused magnitude of interference collection large deviations, and easily making housing distortion is ellipticity so that transverse interference
Amount is big, and the short axle magnitude of interference is little, discontinuity and affect the life-span.
Meanwhile, in use, owing to customer interface feature all designs on housing, motor fixing in car load
All presented by shell characteristics, such actual application environment so that housing connects into transmit with the interference of stator core
Unique bridge of moment of torsion.In order to meet enough moment of torsion transmission, do not interfere with the bonding strength of housing and stator core simultaneously.?
During design, needing the bigger magnitude of interference, technological requirement, the warming temperature of hot jacket are proposed and compare stern challenge by this.
Particularly after temperature is increased to a certain degree, the structural property of case material can be changed, thus have influence on raw-material machinery
Performance.Once there is raw-material modification, be difficult to detect product defects at batch product line, have the risk flowing out bad part.
Need bigger interference in view of hot jacket, need enough housing distortions, Ye You producer to take freezing stator core
Method reduce the difficulty of housing hot jacket, but freezing stator core can cause hydrops and condense frost mist, and the most easy to clean, one
Denier cleaning is not clean, may result in stator core and inner walls cohesion steam, affects electric property and electrical machinery life.
