Abstract
The present invention discloses a method to press in a compressor motor rotor counter balance, which arranges a mold to fix the counter balance on one side of a place for a rotor core counter balance in a die cavity of a high-pressure aluminum casting machine, thus fixing the counter balance and enabling liquefied aluminum to flow into a thru hole in the counter balance during casting. After the liquefied aluminum is cooled, the counter balance is fixed on an aluminum column. The method to press in a motor rotor counter balance integrates two working procedures of firstly aluminum casting and then counter balance pressing-in into one procedure, thus simplifying technique and reducing working period and production cost.
Description
Technical field
The invention belongs to a kind of method of press-fitting of rotor balancing piece, be specifically related to a kind of method of press-fitting of compressor motor rotor balance weight.
Background technology
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electrical appliance of cooling cycle system work.The moving piston of compressor (rolling piston or reciprocating piston) changes mechanical energy into the pressure energy under the drive of motor, realize the compression to the compresser cylinder inner refrigerant.Motor converts electrical energy into the rotary machine energy by the rotation of corresponding component under the current field effect, for the running of compressor provides power.Therefore, motor is the vitals of compressor, and its behavior in service directly influences the function performance of compressor.
In general, motor is made up of stator and rotor two parts, and stator and rotor are made of the iron core that the folded collection of silicon steel core sheet forms respectively.Single stator lamination is circular, and the stator core that is made of the folded collection of lamination is cylindric.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the cylinder cavity of stator core, has air-gap to be separated by between rotor and the stator.Embed the winding of enamelled wire coiled on the stator, stator winding outside source current by the time produce magnetic field.Rotor interacts with stator field when having electric current to pass through, and the generation electromagnetic torque also rotates in stator.
The household electrical appliance that power is slightly little as window air conditioner, wall-hanging air conditioner etc., adopt monophase machine mostly.Be not with the enamelled wire winding on the monophase machine rotor, the electric current in the rotor is not supplied with by external power, but induce by stator field.Induced current and former magnetic field interaction make rotor rotation.
As shown in Figure 1, be moment of torsion that increases rotor and the dynamic balancing of keeping the rotation rotor, additional balance weight on the rotor, stator 1 embeds enamelled wire winding 2 in the form of a ring on the stator 1, and the top of rotor 3 is provided with balance weight 4, and balance weight 4 places the outer circumferential edge on rotor 3 tops.Balance weight 4 is set on the rotor 3 has also increased the moment of torsion of rotor 3.
As shown in Figure 2, be provided with boss 8, in the form of a ring on the top of balance weight 4.Be provided with chassis 5 in the bottom of balance weight 4, chassis 5 is rounded, and boss 8 and chassis 5 one constitute.5 middle body forms through hole 6 on the chassis, and two through holes 7 are set on the plane of boss 8.
Shown in Fig. 3,4, in the prior art, it is two important steps in the rotor moulding that casting aluminum rotor and balance weight are pressed into, common process is to carry out cast aluminium and form casting aluminum rotor 10 and aluminium post 11 with liquidate the earlier rotor core 9 that presses of high pressure aluminium casting machine 12, treating needs with fan it to be cooled off earlier behind the cast aluminium forming, to cast the rotor of aluminium then and put into hydraulic press 14 one by one, and corresponding balance weight 4 is fixed on the aluminium post 11 be pressed into, balance weight 4 be fixed on the rotor 3.The direction that arrow 15 expression hydraulic presses 14 are pressed into.
But the balance weight of prior art is pressed into that processing step is many, man-hour is long, and the manpower and materials expense is big, and product cost increases.
Summary of the invention
The present invention proposes in order to overcome shortcoming of the prior art, and purpose provides a kind of method of press-fitting of motor rotor balance weight, simplifies technology, reduces work hours, reduces product cost.
Technical scheme of the present invention is: a kind of method of press-fitting of compressor motor rotor balance weight, one side of placing the balance weight of rotor core in the die cavity of hydraulic press installs the mould of a stable equilibrium piece additional, fixed-site with balance weight, liquid aluminium flows in the through hole of balance weight when making cast aluminium, after treating the liquid aluminium cooling, balance weight just has been fixed on the aluminium post.Hydraulic press is the high pressure aluminium casting machine.
The method of press-fitting of motor rotor balance weight of the present invention is merged into an operation with being pressed into two operations of balance weight behind the first cast aluminium, has simplified technology, has reduced man-hour, has reduced product cost.
