Embodiment
One of core of the present utility model is to provide a kind of motor stator punching of rotor compressor, to can avoid the motor stator endoporus when assembling in compressor to occur the situation of being out of shape, thereby guarantee the axiality between rotor and stator, reduce the energy consumption of compressor, the useful life that reduces to vibrate and improve compressor.
Another core of the present utility model is to provide a kind of rotor compressor with above-mentioned motor stator punching.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2, the structural representation of the motor stator punching that Fig. 2 is the rotor compressor that provides in the utility model embodiment.
Stator inner hole 1 is provided on the motor stator punching of the rotor compressor providing in the utility model embodiment, and the week of stator inner hole 1 is upwards provided with radiating groove 2, for current motor stator punching, the core improvement of the motor stator punching in the present embodiment is, on the external margin of motor stator punching, also offer the outer rim groove 3 circumferentially distributing along motor stator punching, and the lug boss 5 between the obstruct section 4 between adjacent two radiating grooves 2 and adjacent two outer rim grooves 3 is oppositely arranged, meaning is obstruct section 4 and lug boss 5 corresponding setting one by one diametrically, as shown in Figure 2.
After a plurality of above-mentioned motor stator punchings are superimposed, will form motor stator, due to the outer rim groove 3 of having offered on the external margin of motor stator punching along circumferential distribution, thereby also just formed lug boss 5 between adjacent two outer rim grooves 3, in the timing of rotor compression engine housing shrink-on, the position contacting with rotor compression engine housing should be the lug boss 5 on motor stator punching external margin, and obstruct section 4 between lug boss 5 and adjacent two radiating grooves 2 is oppositely arranged, thereby the pressure that compressor housing gives lug boss 5 neutralizes the support force being cut off in portion 4, this just can effectively be avoided motor stator when assembling, to occur the situation of Internal Hole Deformation, guarantee the axiality between rotor and stator, thereby reduction energy consumption, reduce to vibrate and improve the useful life of compressor.
In order further to optimize the technical scheme in above-described embodiment, radiating groove 2 being circumferentially uniformly distributed along stator inner hole 1 of the motor stator punching in the present embodiment, outer rim groove 3 also being circumferentially uniformly distributed along motor stator punching on the external margin of motor stator punching, this can be so that in the process of hot jacket assembling, motor stator is stressed more even what make progress in week, thereby further avoid stator inner hole 1 that deformation occurs, guarantee the axiality of motor stator and rotor.
And radiating groove 2 can also make motor in when work along being circumferentially uniformly distributed of stator inner hole 1, and the heat producing between rotor and stator can distribute uniformly, avoid because of the inhomogeneous abnormal situation that occurs that the motor feels hot of dispelling the heat.
The shape of the radiating groove 2 of offering on stator inner hole 1 can have multiple, for example radiating groove 2 is the rectangular recess radially being extended towards the external margin of motor stator punching by stator inner hole 1 edge, further, the bottom land of rectangular recess is symmetrical about the radius of motor stator punching.
Although the shape of radiating groove 2 is designed to the radiating requirements that rectangle can guarantee motor, but cause the opening on stator inner hole 1 larger along the rectangular recess circumferentially distributing, this is unfavorable for the smooth operation of rotor, obstruct section between adjacent rectangle groove is also rectangle simultaneously, and this easily causes the enabling capabilities of obstruct section root not enough.
Another radiating groove 2 is also provided in the utility model embodiment for this reason, concrete, this radiating groove 2 is radially extended towards the external margin of motor stator punching by stator inner hole edge, and the bottom land of radiating groove 2 is the arcuation bottom land about motor stator punching symmetry.As shown in Figure 2, because the bottom land of radiating groove 2 is arcuation bottom land, thereby the root of the obstruct section 4 between adjacent two radiating grooves 2 is arc-shaped transition structure, and this can effectively improve the enabling capabilities of obstruct section 4 this kind of structure.Further, the A/F of radiating groove 2 is less than the width of bottom land, and as shown in Figure 2, this can effectively reduce the opening on stator inner hole 1, thereby makes rotor smooth operation.As more preferred mode, the extension edge extending can also be set on obstruct section 4, to further make up the opening on stator inner hole 1, as shown in Figure 2 towards self both sides radiating groove opening.
In order to reduce manufacture difficulty and the cost of manufacture of motor stator punching as far as possible, the rectangular recess that the outer rim groove 3 of the motor stator punching providing in the present embodiment radially extends towards stator inner hole 1 edge for the external margin by motor stator punching, preferably, the line of symmetry of the bottom land of any one radiating groove 2 all overlaps with the center line with its corresponding outer rim groove 3.
As can be seen here, the motor stator punching of the compressor providing in the utility model can effectively be avoided the distortion of stator inner hole 1 when hot jacket is installed, thereby effectively guarantee the axiality of stator and rotor in the motor of compressor, this kind of motor stator punching can also effectively guarantee the uniformity of motor radiating simultaneously.
A kind of rotor compressor is also disclosed in the utility model, comprise motor, and motor comprises stator and rotor, and stator is formed by stacking by motor stator punching, and motor stator punching is the as above motor stator punching of disclosed rotor compressor in any embodiment.
Owing to having comprised the motor stator punching in above-described embodiment in this rotor compressor, thereby this rotor compressor also just had all advantages of the motor stator punching in above-described embodiment concurrently, in present specification, this no longer repeated.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
