Abstract
The utility model relates to a fully enclosed rotor type compressor for air conditioners with double bearing structures. The compressor comprises a casing and a body in the basing. The body comprises a pump body, a motor stator and a motor rotor. The pump body is connected rotatably with the compressor casing through a first bearing that is fixed on the compressor casing and a second bearing that is fixed on the compressor casing and located some distance away from the first bearing. The utility model can efficiently restrict the deflection of the crankshaft, so as to improve the performance of the rotor compressor. The crankshaft is changed from a cantilever arm structure with single restriction into a free beam with double restrictions, so the force application on the crankshaft and an upper cylinder head is greatly improved. The double bearing structures can greatly reduce the crankshaft deformation caused by electromagnetic force, so that the crankshaft almost has no deflection deformation, which results in the following advantages: improved compressor performance; reduced wear loss between the crankshaft and the inner diameter of the upper cylinder head; maintained surface contact between the piston and the cylinder head and the intermediate board; reduced wear rate of end of piston, upper and lower cylinder head, prolonged design service life; reduced unevenness in clearance of the stator and rotor, enhanced motor efficiency; reduced rigidity in the casing of the compressor with big casing diameter, and enhanced casing vibration while low noise maintained.
Description
Technical field
The utility model relates to the air conditioner refrigerating field, especially about a kind of air conditioner full closed rolling rotor type compressor with double supporting structure.This compressor can improve the bent axle reliability of operation, reduces the noise of compressor operating.
Background technique
Fig. 1 is the cross-sectional schematic of traditional air condition compressor.As shown in Figure 1, compressor 9 includes a pump housing of being made up of upper cylinder cover 92, intermediate plate 93 and following cylinder cap 94 and piston and the housing that holds the pump housing.Wherein upper cylinder cover 92 is connected with a sucking pipe 91, and following cylinder cap 94 is connected with an outlet pipe 95, and is connected with a liquid-storage container 96 on the intermediate plate 93.
Have only bent axle and rotor 8 to rotate in the working procedure of compressor 9, compressor 9 pump housing parts upper cylinder covers 92, intermediate plate 93 and following cylinder cap 94 need be welded on the housing.Existing rotor compressor 9 all adopts rotor 8 by on the rotating casing that is fixed in compressor 9 of independent, support 7 mode on upper cylinder cover 92 or the intermediate plate 93 of being fixed on.If regard rotor 8 as a beam, the modes that this upper cylinder cover 92 or intermediate plate 93 supports separately are actually a kind of supporting structure of overhang, bent axle under the constraint of upper cylinder cover 92 or intermediate plate 93 as the circumference pressurized gas that rotatablely moves.
The way of restraint of this supporting structure brings following shortcoming.Bent axle is the cantilever structure of single constraint, is easy to generate bigger distortion, and particularly in the rotor compressor of big discharge capacity, the length of bent axle extends, the stressed increase of eccentric part, and the axial electromagnetic force of electric motor starting increases, and above factor all causes the bent axle amount of deflection to become big.The bent axle amount of deflection becomes conference and brings following adverse consequences.The first, bent axle amount of deflection change senior general increases the contact pressure between bent axle and the bearing, has aggravated the abrasion between bent axle and the upper cylinder cover internal diameter; The second, the face that the bent axle amount of deflection becomes ambassador's piston and cylinder cap and intermediate plate contact and becomes the line contact, causes piston end surface, the cylinder cap end face wears away and speeds up up and down, does not reach projected life; The 3rd, the bent axle amount of deflection becomes the ricing that causes the rotor gap greatly and increases, and must reduce electric efficiency when causing motor noise to increase.The 4th, the increase of the discharge capacity of rotor compressor causes that shell directly becomes greatly, and large shell caliber compressor housing rigidity reduces, and hull vibration is strengthened, and noise is higher.Big capacity compressors unbalance moment strengthens, and housing will produce bigger noise under the driving of unbalance moment.
Summary of the invention

The purpose of this utility model is to provide a kind of air conditioner full closed rolling rotor type compressor with double supporting structure, this compressor becomes traditional rotor list supporting cantilever beam structure the simple beam structure of dual-supporting, thereby significantly reduced the bent axle amount of deflection, keep the face contact between piston and cylinder cap and the intermediate plate, reduce piston end surface, the abrasion of cylinder cap end face speed up up and down, prolong projected life.
The purpose of this utility model is to provide a kind of air conditioner full closed rolling rotor type compressor with double supporting structure, this compressor becomes traditional rotor list supporting cantilever beam structure the simple beam structure of dual-supporting, thereby significantly reduced the bent axle amount of deflection, reduce the ricing in stator and rotor gap, increase electric efficiency.
The purpose of this utility model is to provide a kind of air conditioner full closed rolling rotor type compressor with double supporting structure, this compressor becomes traditional rotor list supporting cantilever beam structure the simple beam structure of dual-supporting, thereby significantly reduced the bent axle amount of deflection, when the increase of the discharge capacity of rotor compressor, though it is big that shell directly becomes, large shell caliber compressor housing rigidity reduces, hull vibration is strengthened, big capacity compressors unbalance moment strengthens, and housing will produce bigger noise under the driving of unbalance moment.But adopt this dual-support structure still to keep lower noise level.
In order to achieve the above object, the utility model provides a kind of air conditioner full closed rolling rotor type compressor with double supporting structure, and the body that compressor includes a housing and is contained in casing inside, body comprise a pump housing and electric machine rotor.The pump housing be fixed in by one that first on the compressor case supports and one be fixed on the compressor case and with first support rotating being connected on the compressor case of second support separated by a distance.
Compare with traditional air condition compressor, the beneficial effects of the utility model be can the operative constraint bent axle scratch, the rotor compressor performance is improved.Bent axle is become the single beam structure of two constraints by the cantilever fine strain of millet structure of single constraint, the stressed of bent axle and upper cylinder cover improves greatly, the crankshaft deformation that dual-support structure can cause the starting electromagnetic force significantly reduces, make bent axle almost not have deflection deformation, thereby make it have following advantage: improve compressor performance; Alleviate the attrition between bent axle and the upper cylinder cover internal diameter; Keep the face contact between piston and cylinder cap and the intermediate plate, reduce piston end surface, cylinder cap end face abrasion speed up and down, prolong projected life; Reduce the ricing in stator and rotor gap, increase electric efficiency; Large shell caliber compressor housing rigidity reduces, and hull vibration is strengthened, but still can keep lower noise level.
