Abstract
The invention relates to a bearing for a rotating compressor cylinder, comprising a compressor inner core and an outer ring, wherein the inner core is made of metal, the outer ring is made of plastics, and a stretching part on the outer circle of the inner core penetrates through the outer ring. The invention also provides a production method of the bearing, comprising the following steps: 1. preparing the inner core with required shape and size by using metal; and 2. carrying out integrated injection molding on the inner core as a die core and the plastic so as to obtain the bearing for the rotating compressor cylinder. The bearing and the production method have the following advantages: 1. since the outer ring of the bearing for the rotating compressor cylinder is made of plastics, and the density is far less than that of metal, the weight of the whole bearing can be greatly reduced, and further the self-weight of a compressor system can be reduced; 2. compared with metal materials, the damping effect of plastics is obvious, so that vibration of the compressor system can be effectively reduced and noise caused by vibration can be lowered; and 3. since the bearing for the rotating compressor cylinder is formed by integrated injection molding of the inner core and the outer ring, the production is very convenient.
Description
Technical field
The present invention relates to a kind of compressor part and manufacture method thereof.
Background technique
Rotary compressor, also known as rolling rotor type compressor, it utilizes piston to rotate to compress refrigerant gas, be one of the most frequently used at present compressor.
The critical piece of rotary compressor is compression assembly, the eccentric crankshaft that it comprises cylinder, the piston be arranged in cylinder, driven plunger make eccentric rotary, is arranged on the slide plate in the vane slot of cylinder and the bearing for supporting bent axle; Its venting gas appliance comprises the bearing valve seat be arranged on main bearing and the exhaust valve plate, spring and the snubber that are arranged in bearing valve seat; Bearing seat bottom portion is provided with valve seat steam vent, is spacing hole above valve seat steam vent; Exhaust valve plate is undertaken in valve seat steam vent, and slides up and down along the axial direction of spacing hole; Snubber is positioned at above exhaust valve plate, and is fixedly connected with spacing hole inwall; Spring is crimped between exhaust valve plate and snubber.
Rotary compression machine bearing is separately positioned on cylinder both sides, and the side because of bearing is the inner cavity surface of cylinder, and it needs to bear hyperbaric environment, and therefore bearing is all made of metal for a long time, and its weight is large, and vibrations are large, noise is large and price is higher.
Summary of the invention
Technical problem to be solved by this invention be overcome prior art above-mentioned deficiency and a kind of rotary compressor cylinder bearing is provided, compressor assembly weight can be alleviated, reduce vibration, reduce noise.
Present invention also offers a kind of manufacture method of rotary compressor cylinder bearing, make that bearing mnanufacture is simple, cost is low.
The present invention solves the problems of the technologies described above adopted technological scheme:
Rotary compressor cylinder bearing, is characterized in that: comprise compressor inner core, outer shroud, and inner core is metal, and outer shroud is plastics, and the elongator on inner core outer ring is through outer shroud.
Better, above-mentioned outer shroud and inner core are injection molded into one, more convenient like this making.
Better, described plastics are selected from one or several of following composition: polyamide-based, polyesters, polyethers, TPO, fragrant heterocyclic, fluorinated polymer, polymer matrix composites and their derivative.
Better, above-mentioned inner core outer ring is rough surface, and such plastics are more easily engaged with inner core, makes not easily to depart from therebetween.
The outer ring of above-mentioned inner core is also provided with groove, to increase plastics and inner core and outer interannular Adhesion force, prevents the disengaging of inner core and outer interannular.
Invention accordingly provides the manufacture method of rotary compressor cylinder bearing, it comprises the steps:
(1) inner core of required form and size, is gone out with preparation of metals;
(2), inner core is injection molded into as mold core and plastics integrally obtains rotary compressor cylinder bearing again.
Above-mentioned injection temperature is 100-300 DEG C.
Compared with prior art, the invention has the advantages that:
1, because the outer shroud of rotary compressor cylinder bearing is plastics, its density is much smaller than metal, therefore the weight of whole bearing can significantly alleviate, and then alleviates compressor assembly deadweight.
2, contrast metallic material, the damping function of plastics is obvious, can effectively reduce the vibrations of compressor assembly and reduce consequent noise.
3, rotary compressor cylinder bearing is injection molded into one by inner core and outer shroud, therefore manufactures very convenient.
Accompanying drawing explanation
Fig. 1 is the configuration diagram of embodiment of the present invention rotary compressor cylinder bearing.
Fig. 2 is the left view of embodiment of the present invention rotary compressor cylinder bearing.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As shown in Figure 1 and Figure 2, rotary compressor cylinder bearing, comprises inner core 2, outer shroud 1, inner core 2 is made up of metallic material, outer shroud 1 is plastics, and whole bearing, can be fixed on the cylinder baffle of compressor by elongator 21 through outer shroud 1 by the elongator 21 on its outer ring by inner core like this.
In the present embodiment, elongator 21 is cylinder, and quantity is three, arranges along inner core 2 even circumferential.
Also shape and the quantity of elongator 21 can be changed according to actual conditions.
In another embodiment, the outer ring of inner core 2 is rough surface (not shown in FIG.), and just can be bonded in more firmly on inner core 2 during such plastics injection moulding, therefore outer shroud 1 and inner core 2 can be closely linked, and not easily throw off.
Certainly, the outer ring of inner core 2 can also arrange groove, or make its other structures shaggy, can play when making plastics injection moulding and just can be bonded in more firmly on inner core 2.
The present invention also accordingly provides the manufacture method of above-mentioned rotary compressor cylinder bearing, and it comprises the steps:
(1) inner core of required form and size, is gone out with preparation of metals;
(2), again inner core is injection molded into one as mold core and plastics, obtains rotary compressor cylinder bearing.
In said method, the temperature of injection moulding is 100-300 DEG C, just can produce qualified cold rotary compressor cylinder bearing.
