Abstract
The invention discloses a fixing structure of a compressor shell and a compressor motor, which comprises a compressor shell and a compressor motor; more than three grooves are arranged on and distributed along the inner surface of the compressor shell; more than three bosses are arranged on and distributed along the outer circumferential surface of a stator lamination of the motor, and the quantity of the bosses are the same with that of the groove. The fixing structure has simple structure and convenient installation and effectively reduces rejection ratio.
Description
Technical field
The invention belongs to the means of fixation of a kind of compressor and motor, be specifically related to a kind of compressor housing simple in structure, easy for installation and the fixed structure of motor.
Background technique
Usually, motor is as the driving source of the most of household electric appliance such as fan in compressor, washing machine, the air conditioner.Because brushless direct current motor has replaced brush and commutator with electron rectifier, so it had both had the simple in structure, reliable, easy to maintenance of Wechselstrommotor, possess the operational efficiency height of direct current motor, no excitation loss and good speed adjustment features again, can avoid again producing plurality of advantages such as mechanicalness noise and electromagnetic noise, be widely used in comprising the national economy every field of household electric appliance.
Motor mainly is made of stator and rotor two-part, and stator has independently loop construction, and permanent-magnet steel is arranged in the rotor.Stator and rotor are made of the iron core that silicon steel plate stacking forms respectively.It is cylindric that stator is, and circle upwards is provided with groove in it.
Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the stator cylinder cavity, and certain space is arranged between stator and rotor.Stator has the winding of high strength enamelled wire coiled, and staor winding is connected with external power, outside source current by the time this electric current and the rotor permanent-magnet steel magnetic field interaction that produced, produce electromagnetic torque and drive the rotor rotation.
Staor winding is by constituting as the main winding of running winding with as the secondary winding that starts winding, winding is to insert an end of coil on the circle in two grooves in a plurality of grooves and insert the other end in stator in other two grooves, is wound with a plurality of windings in stator core.Therefore, be provided with the upper and lower of winding in the top and bottom of stator core, and be fixed with the top and bottom of fixed component in stator core.
In the compressor of air conditioner,, often motor and compressor are installed together a shared housing in order to reduce volume.
As shown in Figure 1; the mount mode of the compressor housing of prior art and motor is: earlier with compressor housing 1 heating, again motor 2 hot chargings 1 li of compressor housing, make compressor housing 1 and motor 2 fixing after the cooling; then loam cake 3 is covered in the upper end portion of housing 1, with protection motor 2.
But, though the hot charging operation of prior art can prevent the mutual rotation between housing 1 and the motor 2 within the specific limits, the relative position of energy stationary housing 1 and motor 2, but, the process conditions of heating and hot charging are wayward, time-consuming in this hot charging operation, in case take place bad, remedy the cost height, so reject rate is higher.
Summary of the invention
The present invention proposes in order to overcome the shortcoming that exists in the prior art, and purpose provides a kind of compressor housing simple in structure, easy for installation and the fixed structure of motor.
Technological scheme of the present invention is: the fixed structure of a kind of compressor housing and motor, comprise compressor housing and motor, and be provided with groove more than three at the compressor housing internal surface, the present invention is provided with three, and is uniform along the internal surface of housing.The outer peripheral surface of the stator lasmination of motor is provided with the boss more than three, and the present invention is provided with three, and its quantity is identical with the quantity of groove, and uniform along the outer peripheral surface of the stator lasmination of motor, it is corresponding with groove that the position is set.
During installation, three boss on the motor and three grooves on the compressor housing are aligned, motor is packed in the compressor housing, and the cooperation by groove and boss fixes housing and motor.
The means of fixation of compressor housing of the present invention and motor, simple in structure, easy for installation, the rate of reducing the number of rejects and seconds effectively.
Description of drawings
Fig. 1 is the compressor housing of prior art and the scheme of installation of motor;
Fig. 2 is the scheme of installation of compressor housing of the present invention and motor.
Wherein:
1 compressor housing, 2 motors
3 loam cakes, 4 compressor housings
5 motor stators, 6 grooves
7 projectioies
Embodiment
With embodiment the fixed structure of compressor housing of the present invention and motor is elaborated with reference to the accompanying drawings:
As shown in Figure 2, the fixed structure of compressor housing of the present invention and motor is included in compressor housing 4 internal surfaces and is provided with groove 6 more than three, and the present invention is provided with three, and is uniform along the internal surface of housing 4.The outer peripheral surface of the stator lasmination of motor 5 is provided with the boss 7 more than three, and the present invention is provided with three, and is uniform along the outer peripheral surface of the stator lasmination of motor 5.Its quantity is identical with the quantity of groove 6, and it is corresponding with groove 6 that the position is set.
During installation, three boss on the motor 57 and three grooves 6 on the compressor housing 4 are aligned, motor 5 is packed in the compressor housing 4, and the cooperation by groove 6 and boss 7 fixes housing 4 and motor 5.
The setting depth of motor 5 in compressor housing 4 guarantees by the length of groove 6, and the length of groove 6 is determined by height and other installation requirement of the stator lasmination of motor 5.Add that simultaneously loam cake guarantees that motor can not move axially.
The means of fixation of compressor housing of the present invention and motor, simple in structure, easy for installation, the rate of reducing the number of rejects and seconds effectively.
