Description
Technical field
The utility model relates to the compressor block of the stationary housing of a kind of compressor inside.
Background technique
At present, compressor obtains using very widely in life and engineering, compressor is the heart of refrigeration system, it sucks the refrigerant gas of low-temp low-pressure from sucking pipe, after driving piston it is compressed by motor rotation, to the refrigerant gas of outlet pipe discharge High Temperature High Pressure, for refrigeration cycle provides power, thus the refrigeration cycle of realization compression → condensation → expansion → evaporation (heat absorption).Compressor generally is made up of housing, motor, cylinder body, piston, control apparatus (starter and heat protector) and cooling system.
Body plays a part fixed crankshaft and cylinder body in compressor, the stability of body affects the working condition of bent axle to a great extent, and the periodic vibration that bent axle rotatablely moving at work brought to whole compressor has tested the stability of body.And consider the orientation of compressor operating, there is a lot of parameters the fixed position of body according to actual conditions, not that traditional horizontal postive direction is fixed entirely, the body of existing a lot of compressor mostly adopts tripod to fix by positioning hole, though reduced material, some shortcomings arranged in stability.The bent axle of compressor air in rotation drive Piston Compression process can form turbulent flow in inside and produce to impact and make a noise, and these all are that the life-span of compressor is caused adverse factors.
Summary of the invention
The utility model has solved the not strong shortcoming of compressor block stability in the prior art, provides a kind of stability better compressor block.
The utility model has also solved the bigger shortcoming of friction torque when bent axle rotates in the prior art in crankshaft hole, provide a kind of friction torque little compressor block.
Another purpose of the present utility model is to reduce the turbulent impact noise that air sends when the compressor inner loop.
Its technical problem that solves the utility model adopts the ground technological scheme to be: a kind of compressor block, become whole by the foundry goods single forming, comprise the crankshaft hole in the middle of being arranged on, the cylinder-bore vertical with crankshaft hole, wherein, described body is tetragonal closed-in construction, four angles of body are provided with four and do the individual fixedly suspension column of usefulness, the both sides in body face upper cylinder hole are provided with 3 noise reduction cups, one one group as air inlet noise reduction cup and two one group as the exhaust noise silencing cup, two one group noise reduction cup is close to continuous, has the inlet hole and the exhaust port that lead to both sides noise reduction cup on the end face of cylinder-bore, and crankshaft hole is to fix by the stiffening rib of periphery.The diameter of the diameter of crankshaft hole and the end of bent axle matches, and is satisfying under the prerequisite of crankshaft strength, and the diameter at the fixing two ends of crankshaft end is little, can reduce friction torque when rotating in crankshaft hole; Gas flows in cylinder, the reason of pressure produces with the casing wall collision and impacts owing to can form turbulent flow in compressor, the noise that the noise reduction cup can reduce to impact is set, one as air inlet noise reduction cup, other two one group as the exhaust noise silencing cup, because big through the gas pressure of overcompression, speed is also very fast, so being used for 2 in the noise reduction cup of exhaust noise silencing forms one group, the effect of noise reduction is apparent in view like this; Allowing prerequisite following crankshaft hole ground periphery in ground to make stiffening rib in crankshaft hole intensity has fixedly reduced material and has reduced weight; Body is made the square mount structure, and mould is simple in structure when being shaped, and adopts four pin to support structural stability.
The length of crankshaft hole is greater than the length of suspension column, and the end face of crankshaft hole is smooth and process flange, and is being provided with an oil groove on the limit of cylinder-bore.Bent axle can produce the vibration in cycle when rotating in crankshaft hole, bring influence to body, so requiring to bear support force, the joint of bent axle and body also needs to transmit and to spread the shaking force that crankshaft rotating causes, bent axle needs lubricant oil to be lubricated when rotating in crankshaft hole, and oil groove can be deposited lubricant oil and form oil film.
As preferably, place, the upper edge of described noise reduction cup is provided with the step of sinking, and 2 one group noise reduction cup neutral position is provided with fixing column.So the little air inlet noise reduction of the pressure of air inlet cup is only used a cap covers just, but pressure is big during exhaust, gas percussion in the noise reduction cup is big, singly be to add lid can't guarantee safety, so in the noise reduction cup, add fixing column, lid is fixed on the noise reduction cup by fixing column, can lid is unclamped because gas pressure is big.
The end face of described cylinder-bore and the axis normal of cylinder-bore, end face is provided with several fixed holes, and has inlet hole and the exhaust port that leads to both sides noise reduction cup on end face, and the position all is lower than the upper edge of noise reduction cup, is higher than the end of noise reduction cup.
As preferably, the axis horizontal of described inlet hole departs from axis 16-25 ° of cylinder-bore, and the axis horizontal of exhaust port departs from axis 20-30 ° of cylinder-bore, and the axis of exhaust port also departs from axis 25-35 ° of cylinder-bore in vertical direction.
As preferably, have aperture on the wall between described 2 one group the noise reduction cup, aperture and exhaust port are on same axis.2 exhaust noise silencing cups are in the same side, and not and need be interconnected, exhaust port and aperture do not make things convenient for the processing of the aperture on second noise reduction cup on the same line.
Intake requirement is controlled, and considers the actual conditions of the work of compressor, also is provided with the through hole that penetrates the noise reduction cup in described 1 one group the noise reduction cup.
In order to get out of the way the range of movement of bent axle, described cylinder-bore is provided with a positioning hole near an end of crankshaft hole.Locate when being used for installing on the body miscellaneous part.
Described suspension column is provided with screw-threaded counterbore, and be provided with in the screw-threaded counterbore of each suspension column bottom connect suspension column move back the bits hole.Move back the bits hole in the thread bottom setting of each suspension column, manufacturability is better during machining screw, can remove ground iron filings in the screw-threaded counterbore more easily, and adopting perforation is to add need not consider the degree of depth man-hour.
The beneficial effects of the utility model are: body becomes the square mount structure, can simplify the structure of mould, adopt four suspension columns to support body, make compressor more stable, friction torque reduces when adopting the crankshaft hole of minor diameter to support bent axle to make crankshaft rotating work as far as possible, arranges that reasonably the position of noise reduction cup and quantity can effectively reduce turbulence and impact the noise that produces.
