Description
Technical field
The present invention relates to Compressor Technology field more particularly to a kind of production methods of bearing of compressor.
Background technique
Rotary compressor for refrigerant because its high cooling efficiency, it is compact-sized, small in size, light-weight due to be widely used in household
Inside equal air conditioners.
Compression assembly is the pith in rotary compressor for refrigerant, mainly includes cylinder, piston, slide plate, crankshaft, master
Bearing and supplementary bearing.Slide plate is located in cylinder sliding vane groove, and arc end surface connects with piston face, upper bearing (metal), piston, lower bearing
It is sequentially sleeved on crankshaft along the axial direction of crankshaft, forms dynamic sealing, cylinder interior is divided into two gas chambers of high-low pressure, in song
Under the drive of axis, air-breathing, the process of compression, exhaust are completed.
Currently, the preparation about bearing, mainly uses integral casting process, such as sand casting etc. is to melt cast iron
It is bearing unitary solid blank to be cast in die for molding after liquid, it is then real by multiple working procedures such as roughing, finishing
The technique of existing base bearing and supplementary bearing.For the technique there are process complexity, processing efficiency is low, at high cost, product weight is larger；Processing
Inclement condition pollutes the environment；Also, the problem of processing waste material is more, leads to the wasting of resources.
Summary of the invention
It is this method simple process, at low cost the present invention is intended to provide a kind of production method of bearing of compressor.
In order to achieve the above technical purposes, the present invention is using steel pipe or casting tubing and plastic production bearing of compressor, tool
Body is as follows:
A kind of production method of bearing of compressor, the bearing setting are used for the centre bore that crankshaft passes through and including flanges
The periphery of described collar one end is arranged in portion and collar, the flange portion, and the centre bore runs through the collar and method
Blue portion；
It is characterized in that: the end bottom of described one end of the collar is in contact with piston；
The collar is made using steel pipe or casting tubing；Then, collar obtained is placed in bearing die
Corresponding position using plastics by injection molding process manufacturing flange portion, then is finished, obtains the bearing.
The material of the steel pipe is unlimited, including carbon steel tubing and alloy pipe.
When making the collar using steel pipe, preferably, the internal diameter of the steel pipe is equal to the diameter of the centre bore.
The casting tubing is ironcasting, be using casting technique, cast iron is melted for be poured after liquid in a mold at
Type is tubular blank, the tubing then obtained by processes such as processing, polishings.
When making the collar using casting tubing, preferably, the internal diameter of the casting tubing is after finishing etc.
In the diameter of the centre bore.
The shape of the flange portion and structure are unlimited.The flange portion may include the metal insert A with certain function,
For improving the integral strength of flange portion, or for the connection of flange portion and other component, improve connection tightness.At this moment,
Corresponding position is arranged in bearing die in collar and metal insert A first, is then made by injection molding process
Flange portion.
The bearing of compressor can also include turn-up portion；The turn-up portion is fixedly connected on the flange portion outer peripheral edge,
The flange towards the collar other end is formed with the flange portion.Preferably, passing through injection molding process using plastics
Make the turn-up portion.As further preferred, the flange portion and turn-up portion are disposably made by injection molding process.
The shape of the turn-up portion is unlimited with structure, may include the metal insert B with certain function, turns over for improving
The integral strength of edge, or for the connection of turn-up portion and other component, improve connection tightness.At this moment, preferably, it is first
Corresponding position is first arranged in bearing die in collar and metal insert B, then passes through injection molding process facture
Blue portion and turn-up portion.
In the present invention, the injection molding process refers to plastic particles raw materials are heated into fluid in injection molding machine after inject
The manufacture craft of die for molding.The plastics have processable type, and type is unlimited, including poly- phthalein amine, gather cruel class, polyethers
The derivative of the resin materials such as class, polyolefins, heteroaromatic class, fluorine-containing quasi polymer and these resin materials.In view of axis
The performance held, it is preferred to use the plastics with good hardness, wearability and corrosion resistance.
Compared with the production method of existing bearing of compressor, the present invention has the advantage that
(1) present invention directly carries out the production of collar, simple process using steel pipe or casting tubing；In particular by steel
Guan Shi can guarantee collar since steel have good dimensional accuracy, intensity, hardness, rigidity and elasticity modulus
Intensity and hardness, while can guarantee to process the dimensional accuracy of collar obtained, it has a good application prospect.
(2) present invention selects molding steel pipe or casting tubing, according to the shape and size of required collar, processing and fabricating
Collar, is directly utilized the aperture feature of tubing, and collar can be obtained by simple processing technology, with existing founder
Skill has saved material compared to processing capacity is reduced.
(3) for the present invention using plastics by Shooting Technique manufacturing flange portion and turn-up portion, one side plastics are at low cost, another
Aspect is since the density of plastics is much smaller than metal, therefore the weight of entire bearing can substantially mitigate, and then mitigate compressor assembly
Self weight.In addition, comparison metal material, the damping action of plastics is obvious, can effectively reduce the vibration of compressor assembly and reduction
Resulting noise.
