Description
Technical field
The present invention relates to refrigeration compressor motor mounting structure, particularly make accurate compressor motor stator mounting structure.
Background technology
The critical process being compressor in Assembling Production process installed by the motor stator of Piston Refrigerant Compreessor. Air gap (gaps between stator and rotor) size between compressor motor stator and motor rotor and all title degree directly affect electric use properties and the refrigeration of compressor. Air gap is excessive, the magnetic resistance between stator and rotor will be increased, excitation loss is increased, and magnetizing current increases thereupon, and namely the power factor of motor can decline, and makes motor performance become bad. Air gap is crossed and little can be gone over to the opposite side again, makes air gap harmonic wave grow field and increases, and stray loss of motor and noise increase, and torque capacity and pull-in torque are all reduced; And air gap is too little also easily makes the rotor in operation and stator grazing, there is " sweeping thorax " phenomenon, bring difficulty to startup, thus reduce the reliability that motor runs; In addition, also difficulty is brought to assembling. The air gap of general small size asynchronous motor is about between 0.25��1.5mm, and the air gap of medium-sized asynchronous motor is about between 0.75��2mm. All titles degree of motor gas-gap also directly affects motor performance and compressor cooling effect. Non-uniform air-gap is that rotor is eccentric relative to stator, causes motor magnetic circuit asymmetric, causes unilateral magnetic force, also claims unbalanced magnetic pull, and so forth, will directly cause rotor to sweep thorax, and stator and rotor rub, and rotor is stuck, and winding burns. Therefore, motor gas-gap more all claim more good.
Fig. 1, Fig. 2 represent the installation structure of existing piston-type refrigerating compressor motor. This structural electromotor stator 2 is directly fixed on the motor stator erecting stage 4 of Rack Body 1 with screw 6. This kind of structural allocation makes motor stator lack reliable and stable locating structure, and motor stator heavier-weight, the shock of compressor in transportation is easy to cause motor stator to be mounted opposite platform and produces slippage, stator slippage makes air gap between motor stator and rotor offset (motor rotor is fixed on bent axle and can not produce to move), cause air gap big little phenomenon on one side on one side, thus making the refrigeration of compressor and overall performance decline, serious causing turns, friction or stator are stuck and burn out motor between rotor-stator.
The assembling of existing stators for refrigeration compressor motor adopts following two kinds of methods:
One, false rotor is adopted. First a false rotor is inserted in bent axle (false rotor crankshaft hole is corresponding to bent axle external diameter size, and false rotor external diameter is corresponding to stator inner hole size), stator is inserted in false rotor, then is screwed stator, then take out false rotor.Because the crankshaft hole of false rotor and bent axle, false rotor external diameter and stator inner hole, it is necessary to leave certain interval, gap is crossed little false rotor and is difficult to take out, and excessive clearance can cause above-mentioned air gap inequality to claim phenomenon; And take out false rotor and assembly parts are turned around manipulation, both lose time, reduced again production efficiency.
Two, first motor rotor is fixed on bent axle, on overlapping on rotor, one by many frocks that clearance gauge is formed again, motor stator is inserted in clearance gauge frock, see Fig. 1, Fig. 2, (clearance gauge can not be too thick to extract clearance gauge after fixed stator screw, too thick can not pull out out), then turn around in stator and rotor air gap with standard clearance gauge and measure all title degree of air gap, if feel inequality claims just to knock stator with hammer adjusts air gap. This metering system judges all title degree in gap entirely with the sensation of employee's hand and experience, when so assembling motor stator is taken a lot of work, to assembling person manually precisely the technical ability such as degree require high, unstable product quality, production efficiency is low, it is difficult to realizes automatization and robot installation, and causes product repair rate height.
Summary of the invention
The present invention to be solved to be needed in stators for refrigeration compressor motor assembling process in prior art to use frock, assembling is complicated, to the requirement height of people's operation, not easily realize automatization and robotic asssembly, air gap is easily produced uneven after assembling, compressor is in transportation, compressor be arranged in the transportation on refrigerating appliance produce shock make motor stator produce slippage, cause the decline of compressor electric property and determine, rotor is stuck, motor burns out, the problems such as repair rate height, a kind of stators for refrigeration compressor motor mounting structure of the present invention is provided for this reason, adopt this structural part that compressor motor stator installation procedure can be made to simplify, installation difficulty reduces, stator install accurate degree with install after stability greatly improve, fixed, air gap between rotor all degree of title height, and not easily cause air gap all degree of title reductions because clashing into when complete machine transport is moved, compressor formedness can be ensured, extend motor and compressor work-ing life.
For solving the problem, the technical scheme of its invention has Rack Body, its special character is connected with electronics stator to circumference interval on described Rack Body to install stage, this stator installation stage connects body by the plateau level of low the level in direction, inner side and lateral direction and forms, and low level has offered installation screw.
Preferably the interior side of the plateau level that stage installed by described stator is arc, and the radian of this arc is corresponding to the radian of motor stator outer side.
Preferably on described low level, slot to make way has been offered in junction with the interior side of plateau level, thus avoids described junction plane and perpendicular interfacial angle portion arc angling shape occur, is unfavorable for that the installation that motor stator is good is located in and stable position.
The present invention installs location division according to stator and screw number installs stage at the stator of ground, the circumferential interval of Rack Body processing sets up more than two, circle diameter residing for the plateau level inwall of more than two stator installation stages is corresponding to motor stator outer side circle diameter size, during installation, motor stator embedded seat is fallen within stator stage is installed, with installation screw, motor stator is fixed on the screw of low level of stator installation stage. owing to having the plateau level of stator installation stage when installing as normality, make motor stator easy for installation, simple, quick. the mounting structure of the present invention improves the accurate degree after electric machine rotor assembling, it is fixed to make, air gap between rotor all claims, solve compressor motor stator installation and need frock, stator assembling after air gap all degree of title need measure, reduce the requirement to manual work, improve production efficiency, thus reduce production cost, it is convenient to realize automatization and robotic asssembly, it also avoid compressor makes motor stator be mounted opposite platform generation slippage because clashing in transportation and refrigerating appliance transportation, cause the compressor performance even rotor that declines stuck, the phenomenon that motor burns out, substantially increase the anti-collision performance of compressor, ensure that the reliability of overall mass and stability, the repair rate of compressor is reduced, work-ing life extends. the structural part simple structure of the present invention, but it plays a very important role in compressor total quality ensures.
