Description

Totally-enclosed reciprocating-piston freezer compressor
Technical field
The invention belongs to freezer compressor technical field more particularly to a kind of totally-enclosed reciprocating-piston freezer compressors.
Background technology
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is the heart of refrigeration system It is dirty.It sucks the refrigerant gas of low-temp low-pressure from air intake duct, is operated by motor after being compressed to it with piston, to row The refrigerant gas of high temperature and pressure is discharged in tracheae, and power is provided for refrigeration cycle, to realize compression → condensation (heat release) → swollen The refrigeration cycle of swollen → evaporation (heat absorption).
The quality of one refrigeration for refrigerator quality mainly sees the effect of compressor, and freezer compressor has reciprocating and rotary two Kind specification.In Japan, rotary compressor has occupied 30% or more market, and most compressor for refrigerator are main at present in China Based on reciprocating-piston, production line uses Reciprocting piston compressor, and freezer compressor market accounts for 87% at home Left and right.
Freezer compressor need to run 10 in high temperature and under being filled with the sealing condition of refrigerant and refrigerator oil without monitoring Year or so, therefore requirement operates steadily, reliability is high, efficient, refrigerating speed is fast, noise is low, starting performance is good, while press device The vibration generated when operating can make pipeline and system generate resonance and increase noise, therefore, it is necessary to which vibration is limited in certain water It is flat.
Existing reciprocating compressor of refrigerator is usually by compressor body and motor with hanging spring or marshall springs is supported on lower casing In vivo, upper shell and lower housing joint are shut with electric welding, and spring structure is complicated, spring steel is expensive, bent axle volume Greatly, factors all increase the volume and cost of compressor again etc. for piston and connecting rod quality.
Invention content
The present invention overcomes the deficiencies in the prior art, provide a kind of totally-enclosed reciprocating-piston freezer compressor, pass through method Orchid replaces spring-loaded compressor body and volume, piston and the connecting rod of motor, reduction bent axle microcephaly to be closed using lighter aluminium The method of gold or engineering plastics makes the lighter quality of compressor, volume and noise smaller, stationarity while reducing cost Higher.
The technical scheme is that:
Totally-enclosed reciprocating-piston freezer compressor, including connecting rod, piston, cylinder body, the gas installed in shell and shell The output end of valve, bent axle and motor, motor is connect with bent axle, is connect with the piston in cylinder body by connecting rod at the top of bent axle, cylinder Body is connect with air valve, it is characterised in that:A flange is provided in shell, which is interference fitted with inner walls, motor and method Orchid is fixedly mounted with, and bent axle is rotatably installed in across flange center hole on flange, and cylinder body is packed on flange.
Interference fit is formed between rotor in the bent axle and motor.
The shell is divided into upper shell and lower housing, and there are one annular convex edge, flange and rings for lower housing upper inside wall system Shape convex edge forms interference fit.
The binding post is vertically installed on upper shell, is located at the control of the part and external control compressor outside upper shell Box processed is connected, and the part being located in upper shell is connected with the motor down-lead inside compressor.
The mode that is fixedly mounted between the motor and flange, cylinder body and flange is:It is bolted;In addition other also can be used It is fixedly mounted with mode, is such as threadedly coupled, welding, riveting, is glued.
The piston and connecting rod material is aluminium alloy or engineering plastics, and the material of flange is cast iron.
Above-mentioned bent axle includes being respectively arranged with bent axle microcephaly, balance portion and main shaft from top to bottom;Spindle outer wall from upper and It is arranged with fuel feed hole, oil circuit slot, the first oil outlet, venthole, main shaft bottom centre position is provided with oil-sucking hole, is set on main shaft It is equipped with oil circuit, boss, the top surface connection of bent axle microcephaly bottom surface and boss, the top of boss are provided between bent axle microcephaly and balance portion The second oil outlet is additionally provided on face, boss bottom surface is connect with balance portion top surface, and balance portion bottom surface is connected with main shaft.
The setting of bent axle microcephaly's bias is on boss, and more existing bent axle microcephaly volume smaller, quality is lighter, and Increase its wearability by special surface treatment, surface treatment method is chemical spray, and other increase surfaces can also be used The surface treatment gimmick of wearability.
The diameters of axle ratio of the bent axle microcephaly and main shaft is 1:6-1:3.
The outer diameter of the boss is less than or equal to the outer diameter in balance portion.
The outer diameter of the main shaft is less than the outer diameter in balance portion.
The oil circuit is divided into three parts from bottom to top, and first part is arranged inside main shaft, goes out for oil-sucking hole 9 to the first Part between oilhole;Second part is the oil circuit slot connected between the first oil outlet and fuel feed hole, which is arranged in master Axis outer wall spiral is upward;Part III, which is arranged inside main shaft, is connected to fuel feed hole and the second oil outlet.
The venthole is arranged on the outer wall of main shaft lower end, is connected to the first part of oil circuit.
When the bent axle work of compressor, lubricating oil is sucked from the oil-sucking hole of main shaft bottom, under the influence of centrifugal force, lubrication Oil is upward all the way along oil circuit, by oil circuit first part, is thrown away from this oil outlet to corresponding when flowing at the first oil outlet Component is lubricated, and subsequent lubricating oil continues up flowing along oil circuit slot, enters oil circuit Part III from fuel feed hole, finally by Second oil outlet is thrown away, and lubricates corresponding component around it, and the gas existed in oil circuit is discharged by venthole.
Compared with prior art, the beneficial effects of the invention are as follows:
(1) castiron flange is arranged in Dimensions Used in Shell of Refrigerator Compressor using the connection type of interference fit by the present invention Interior, the spring that is made instead of spring steel in prior art freezer compressor supports freezer compressor ontology and motor, significantly Reduce the volume of compressor, while reducing cost;
