Abstract
The invention provides a rolling piston for a compressor. The rolling piston comprises an outer sleeve, an inner sleeve and a supporting ring; the inner sleeve comprises two single inner sleeve bodies, each single inner sleeve body is an inverted-T-shaped hollow cylinder, and ports of vertical planes of the two single inner sleeve bodies are connected together through a supporting ring; and the outer sleeve is a pipe matched with the inner sleeve and is fixed outside the connected inner sleeve. The invention further provides a manufacturing method for the rolling piston for the compressor. Because the inner sleeve of the rolling piston is separated into the two single inner sleeve bodies and the single inner sleeve bodies can be formed in one step, existing cutting methods can be eliminated, lots of materials can be saved and the production cost can be low; because the two single inner sleeve bodies of the inner sleeve are connected together through the supporting ring, the supporting ring can be located in the middle of the rolling piston; and under the supporting effect of the supporting ring, the middle of the rolling piston can be effectively supported on the premise that the weight is reduced, and therefore products do not get deformed easily in the long-term use process, and the performance is good.
Description
Technical field
The present invention relates to a kind of compressor part, particularly to a kind of compressor rolling piston.
Background technology
Rotary compressor for refrigerant, also known as rolling rotor compressor, it is carried out to refrigerant gas using piston rotation
Compression, has put much years on market, it is one of compressor the most frequently used at present.
Rolling piston is the strength member of rotary compressor for refrigerant set, and it is arranged on the bias of the eccentric shaft of compressor and turns
On, roll along cylinder wall during refrigeration, the slide plate cylindrical wall close contact with rolling-rotor under spring force, composition is dynamic
Sealing, is becomed more diverse using novel environment-friendly refrigerant, high efficiency and energy-conservation etc. with rotary compressor, to can be suitably used for height
Rolling piston under the rigor condition such as load, high power, high temperature, high pressure is put forward higher requirement.
For a long time, rolling piston is solid, and therefore its weight is big.For driving rolling piston rotation, need to spend relatively
Many energy.But there is higher intensity again because rolling piston needs to have preferable frictional behaviour, therefore up to the present
A kind of effective ways saving energy are not found yet.
The applicant has obtained the rolling piston of hollow cylinder through research, though it can mitigate weight, reducing energy consumption, by
In the hollow rolling piston with supporting part for the existing structure, its inner sleeve is cut mid portion by whole pipe and is formed support
Ring, therefore manufacture material that is very complicated and consuming more it is still necessary to find the piston of more preferable structure and manufacture method.
Content of the invention
The technical problem to be solved is to overcome the above-mentioned not enough of prior art and provide a kind of compressor to roll
Piston is so as to being capable of easy to manufacture.
The present invention has also correspondingly provided a kind of compressor rolling piston manufacture method so as to easily manufactured, low cost.
The present invention solves the technical scheme that adopted of above-mentioned technical problem：
Compressor rolling piston, including overcoat, inner sleeve and support ring, inner sleeve includes two inner sleeve monomers, each inner sleeve monomer
It is convex shape hollow cylinder, two inner sleeve monomer vertical ports are linked together by support ring, and overcoat is to join with inner sleeve
The pipe closing, outside the fixing inner sleeve upon connection of overcoat.
Preferably, two inner sleeve monomer shapes are just the same, so only need to manufacture a type of inner sleeve monomer, therefore soon
Speed, convenient, a large amount of manufacture.
Specifically, two inner sleeve monomers also can pass through other conventional meanses by being welded together with support ring
Link together.
Preferably, the connection at above-mentioned jacket and inner sleeve two end is welding and/or interference connects, and such jacket and inner sleeve is fixed
More firm, sealing property is more preferable.
Above-mentioned jacket and inner sleeve also can bond together.
Also correspondingly provide a kind of manufacture method of compressor rolling piston, it comprises the following steps：
1）First one-shot forming goes out two inner sleeve monomers,
2）Again the vertical of two inner sleeve monomers is linked together and is linked together by support ring,
3）It is fixed on corresponding overcoat in connecting and put again.
Above-mentioned two inner sleeve monomers are preferably identical monomer, so easily manufactured, low cost.
The end face that above-mentioned overcoat can pass through inner sleeve two end is welded with junction in pipe or bonds together, and also can pass through
It is full of and cooperate together.
Compared with prior art, it is an advantage of the current invention that：Because rolling piston inner sleeve is divided into two inner sleeve monomers, two
Inner sleeve monomer is identical, therefore, it is possible to convenient and extensive manufacture.
Due to inner sleeve monomer can one-shot forming, it is thus eliminated that existing cutting process, substantial amounts of material can be saved,
Low production cost.
Due also to the two of inner sleeve inner sleeve monomers are linked together by support ring, therefore, support ring is at rolling
The middle part of piston, under the support of support ring, rolling piston can effectively be propped up at middle part on the premise of ensureing to mitigate weight
Support, so that it is guaranteed that product can be unlikely to deform during long-term use, performance is more preferable.
Brief description
Fig. 1 is the decomposition texture schematic diagram of embodiment of the present invention rolling piston inner sleeve.
Fig. 2 is the structural representation of embodiment of the present invention rolling piston.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in figure 1, the inner sleeve of compressor rolling piston, including, inner sleeve monomer 1, inner sleeve monomer 2, inner sleeve monomer 1 with
Inner sleeve monomer 2 is identical.
Inner sleeve monomer 1 is in "convex" shaped cylinder, inner sleeve monomer 1 middle setting cavity 11, and one end is chimb 13, perpendicular to convex
The other end on side 13 is joint face 12.
Equally, inner sleeve monomer 2 is in "convex" shaped cylinder, inner sleeve monomer 2 middle setting cavity 21, and one end is chimb 23, hangs down
The straight other end in chimb 23 is joint face 22.

Together.
The biend 12,22 of inner sleeve monomer 1 and inner sleeve monomer 2 can also first weld together, and then welds with support ring 3 again
It is connected together.
As shown in Fig. 2 overcoat 4 is the pipe being just enclosed within outside inner sleeve, overcoat 4 is fixed on above-mentioned inner sleeve after connecting
Outward, overcoat 4 both can weld with inner sleeve, bonding or interference fit, preferably weld.
A kind of manufacture method of compressor rolling piston, it comprises the following steps：
1）First one-shot forming goes out inner sleeve monomer 1,
2）Again the vertical of two inner sleeve monomers 1 is linked together and passes through support ring 3 and link together,
3）It is fixed on corresponding pipe 4 in connecting and put again.
