Description
Technical field
The utility model relates to refrigeration compressor motor mounting structure, particularly makes accurate compressor motor stator mounting structure.
Background technology
It is the critical process of compressor in Assembling Production process that the motor stator of Piston Refrigerant Compreessor is installed.Air gap (gaps between stator and rotor) size between compressor motor stator and rotor and all title degree directly affect electric serviceability and the refrigeration of compressor.Air gap is excessive, and increased by the magnetic resistance made between stator and rotor, excitation loss is increased, and exciting current increases thereupon, and namely the power factor of motor can decline, and motor performance is degenerated.Air gap is too small can go over to the opposite side again, and make air gap harmonic wave grow field and increase, stray loss of motor and noise increase, and breakdown torque and detent torque are all reduced; And air gap is too little also easily makes operating rotor and stator grazing, there is " sweeping thorax " phenomenon, bring difficulty to startup, thus reduce motor reliability of operation; 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 claim unbalanced magnetic pull, and so forth, will directly cause rotor to sweep thorax, and stator and rotor rub, and rotor is stuck, winding.Therefore, motor gas-gap more all claim better.
Fig. 1, Fig. 2 represent the mounting structure of existing piston-type refrigerating compressor motor.This structural electromotor stator 2 is directly fixed on the motor stator mounting platform 4 of Rack Body 1 with screw 6.This structural allocation makes motor stator lack reliable and stable location 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 (rotor is fixed on bent axle can not produce movement), cause air gap large little phenomenon on one side on one side, thus the refrigeration of compressor and overall performance are declined, serious causing turns, between rotor friction or stator stuck and burn out motor.
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 crankshaft external diameter size, and false rotor 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 diameter and stator inner hole, all must leave certain interval, and the too small false rotor in gap is difficult to take out, and excesssive gap can cause above-mentioned air gap dissymmetry phenomenon; And take out false rotor and assembly parts will be turned around operational processes, both lose time, reduced production efficiency again.
Two, first 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 titles degree of air gap, if feel dissymmetry just knocks stator with hammer adjust air gap.This metering system judges all titles degree in gap entirely with the sensation of employee's hand and experience, when so assembling motor stator is taken a lot of work, high to skill set requirements such as the artificial precisions of assembler, unstable product quality, production efficiency is low, is difficult to realize automation and robot installation, and causes product repair rate high.
Summary of the invention
The utility model will solve in prior art to be needed in stators for refrigeration compressor motor assembling process to use frock, assembling is complicated, high to the requirement of people's operation, not easily realize automation 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 compressor electric property to decline and determine, rotor is stuck, motor burns out, the problems such as repair rate is high, a kind of stators for refrigeration compressor motor mounting structure of the present utility model is provided for this reason, adopt this structural member that compressor motor stator installation procedure can be made to simplify, installation difficulty reduces, the precision that stator is installed and the stability after installing improve greatly, fixed, air gap between rotor all degree of title is high, and not easily cause air gap all degree of title reductions because clashing into when complete machine transport is moved, compressor superperformance is ensured, extend motor and compressor useful life.
For solving the problem, the technical scheme of its utility model has Rack Body, its special character is that on described Rack Body, circumferential compartment of terrain is connected with electronics stator installation stage, this stator is installed stage and is made up of low the level in direction, inner side and the plateau level disjunctor of lateral direction, and low level offers installation screw.
Preferably the medial surface of the plateau level of stage installed by described stator is arcwall face, and the radian of this arcwall face is corresponding to the radian of motor stator lateral surface.
Preferably on described low level, offer slot to make way with the junction of the medial surface of plateau level, avoid described junction plane and vertical plane angle of cut portion to occur arc angling shape thus, be unfavorable for that the installation that motor stator is good is located in and stable position.
The utility model installs location division according to stator and screw number installs stage at the stator of the circumferential compartment of terrain processing sets up more than two of Rack Body, residing for the plateau level inwall of more than two stator installation stages, circle diameter is corresponding to motor stator lateral surface circle diameter size, during installation, motor stator embedded seat is fallen within stator and stage is installed, with mounting screw, motor stator is fixed on the screw that low level of stage installed by stator.Owing to there being stator to install the plateau level of stage as normality when installing, make motor stator easy for installation, simple, quick.Mounting structure of the present utility model improves the precision after electric machine rotor assembling, it is fixed to make, air gap between rotor all claims, solve compressor motor stator installation and need frock, the rear air gap of stator assembling all degree of title needs to measure, reduce the requirement to manual work, improve production efficiency, thus reduce production cost, be convenient to realize automation 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 reliability and the stability of overall mass, the repair rate of compressor is reduced, useful life extends.Structural members of the present utility model is simple, but it plays a very important role in compressor total quality ensures.
