Abstract
The utility model provides a balanced weight used for motor rotors, belonging to the mechanic material technique field. The utility model solves the defects that the material price is too high and the requirements can not be well satisfied in the prior art. The balanced weight is fixed on the motor rotor and made of high manganese steel material, and is fabricated through forging process. The balanced weight used for the motor rotors disclosed in the utility model can not only satisfy special requirements applied to the motor rotors with low material price, but also the balanced weight fabricated by forging has no casting shrink holes with stable center of gravity.
Description
Technical field
The utility model belongs to the mechanical material technical field, relates to a kind of balance weight of rotor, particularly a kind of balance weight that is used for the compressor rotor of air-conditioning, refrigerator.
Background technology
The compressor of air-conditioning, refrigerator generally comprises motor and compression pump, and rotating shaft one end and rotor on the motor are connected, and the rotor in the other end and the compression pump is connected.Because be provided with eccentric stiffener in the compression pump, in the time of motor-driven compression pump working rotor, the rotating shaft of motor just will inevitably produce vibration, so just need balance weight be set on rotor and eliminate vibration, increases the service life.
Rotor, motor cabinet, piston, connecting rod, cylinder, balance weight, fan blade and air accumulator, its course of work is that rotor rotates, the driven equilibrium piece rotates around motor shaft, the drivening rod motion, piston is moved reciprocatingly in cylinder, compressed air enters air accumulator, and fan blade is installed in the other end of machine shaft.And the piston type reciprocating machine will inevitably produce vibration, particularly rotor and the axis of the piston are one in the compressor, and wherein piston is eccentric the setting, therefore balance weight must be set on rotor, the center of gravity of rotor is on the machine shaft, could reduce the vibration of motor like this, increase the service life.
The material of the balance weight of this use on rotor must meet following condition: 1, nonmagnetic or low magnetic conductivity; 2, no work magnetic; 3, material will have certain quality density, and motor volume is reduced.In the prior art, balance weight all adopts copper alloy made, and still along with the more and more scarcity of copper resource, the price one of copper rises and rises again, if re-use the copper product making product cost of producing is increased, and greatly reduces competitiveness; For this reason, the balance weight that the someone uses Zinc material to manufacture, but the kirsite mass density is less than normal will meet the requirements of bigger that the mass balance piece just need do, and this makes motor become clumsy; In the same industry, use austenitic steel to make in addition, need very high nickel content but austenitic steel is made balance weight, nickel is again precious metal, and price is not low yet, and can produce work magnetic at the balance weight of making, do not satisfy the requirement of above-mentioned balance weight material.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at existing balance weight, the balance weight that provides a kind of rotor to use, and requirement but also material price that it not only meets the balance weight material that rotor uses are cheap.
The purpose of this utility model can realize by following technical proposal: the balance weight that a kind of rotor is used, be fixed on the rotor of motor, and it is characterized in that this balance weight adopts high manganese steel material to make.Balance weight is made and creatively to be used high manganese steel material not only to meet the specific (special) requirements of use on rotor, and with existing mature technology in use the mass density of copper alloy approaching, the more important thing is its low price.
In the balance weight that above-mentioned rotor is used, described high manganese steel material is a kind of among 20Mn13,20Mn18,20Mn23Al or the 20Mn23AlV.Facts have proved that these several high manganese steel materials are made balance weight and had effect preferably.
In the balance weight that above-mentioned rotor is used, described balance weight is fan-shaped or semicircular or circular.The various balance weight of shape can be fit to different rotors.
In the balance weight that above-mentioned rotor is used, described balance weight is provided with rivet hole.Balance weight can be riveted on the rotor by rivet hole.
Compared with prior art, balance weight that the utility model rotor is used adopts high manganese steel material to make, and not only meets the specific (special) requirements that is used on the rotor (as nonmagnetic or low magnetic conductivity; No work magnetic; Material has certain quality density etc.), and this material price is cheap; Forge and press produced balance weight and do not have casting shrinking hole, steadily of centre of gravity.

Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, rotor 1, rotating shaft 2, pump rotor 3 etc. are arranged in the compressor of the present utility model, rotor 1 is connected in rotating shaft 2 one ends, pump rotor 3 off-centre are fixed on the other end of rotating shaft 2, when rotor 1 rotates, it is not steady that the eccentric pump rotor 3 that is provided with rotates rotating shaft 2, therefore in the end of rotor 1 balance weight 4 is set.Described rotor 1 comprises magnetic core 11, supports the upper head plate 12 and the bottom plate 13 of magnetic core, fixes a balance weight 4 with rivet on bottom plate 13.This balance weight 4 is semicircular, is provided with two rivet holes on its end face, as shown in Figure 2.
As shown in Figure 3, embodiment 3 is basic identical with embodiment 1, and difference is that the shape of balance weight 4 is circular, fixes a projection that is tile on it and is used for gaining in weight.
As shown in Figure 4, embodiment 3 is basic identical with embodiment 1, and difference is that the shape of balance weight 4 is fan-shaped, fixes a projection on it and is used for gaining in weight.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as rotor 1, rotating shaft 2, pump rotor 3, balance weight 4, iron core 11, upper head plate 12, bottom plate 13 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
