Abstract

The invention provides a rolling piston used for a compressor. The rolling piston comprises two half piston bodies. Each half piston body is internally provided with a cavity. The two half piston bodies are axially and integrally welded. According to the rolling piston used for the compressor, due to the fact that the rolling piston is divided into the two half piston bodies which are connected together through welding, manufacturing is convenient; and in addition, the piston cavities can be filled with materials with the proportion being lower than that of piston materials as needed, and hence the piston can be supported and is not prone to being deformed on the premise of ensuring that the weight of the whole piston is reduced, so that the product performance is ensured.

Description

A kind of compressor rolling piston
Technical field
The present invention relates to a kind of compressor part.
Background technology
Rotary compressor for refrigerant, also known as rolling rotor compressor, it utilizes piston to rotate and is compressed refrigerant gas, has put much years on market, and it is one of the most the most frequently used compressor.
Rolling piston is the strength member of rotary compressor for refrigerant set, the bias of its eccentric shaft being arranged on compressor turns, roll along cylinder wall during refrigeration, slide plate under spring force with the cylindrical wall close contact of rolling-rotor, composition movable sealing, along with rotary compressor uses novel environment-friendly refrigerant, high efficiency and energy-conservation etc. becomes more diverse, the rolling piston that can be suitably used under the rigor condition such as high load capacity, high power, high temperature, high pressure is had higher requirement.
For a long time, rolling piston is solid, and therefore its weight is big.For driving rolling piston to rotate, need to spend more energy.But there is higher intensity again owing to rolling piston needs possess preferable frictional behaviour, the most do not find a kind of effective ways saving energy.
The applicant has obtained the rolling piston of hollow cylinder through research, though it can alleviate weight, reduces energy consumption, but owing to the hollow cylinder of existing structure is not easy to manufacture, it is therefore desirable to find the piston of more preferable structure.
Summary of the invention
The technical problem to be solved is to overcome the above-mentioned deficiency of prior art to provide a kind of compressor rolling piston so that it is can easily manufacture.
The present invention solves the technical scheme that above-mentioned technical problem used:
Compressor rolling piston, including two and half pistons, arranges cavity in each half piston, and two and half pistons are the most integrally welded.
Specifically, according to concrete conditions such as bonding strength and piston sizes, above-mentioned welding is arranged on outer connecting end surface and/or the interior connecting end surface of two and half pistons.
Preferably, connect also by interference fit between the connection end of two and half pistons, fixing more firm between such two and half pistons, seal more preferably.
Specifically, according to concrete conditions such as bonding strength and piston sizes, above-mentioned interference connection is arranged on outer connecting end surface and/or the interior connecting end surface of two and half pistons.
Preferably, the cavity of half piston can be filled fill up proportion less than piston material material.
Preferably, above-mentioned substance is resin or plastics, can conveniently inject cavity.Obviously, above-mentioned substance is alternatively the material of other similarities.
Preferably, above-mentioned substance is the resin that with the addition of firming agent, so can inject at normal temperatures and solidify.
Compared with prior art, it is an advantage of the current invention that: owing to rolling piston is divided into two and half pistons and by being welded together, therefore manufacture more convenient.Also having proportion in piston cavity to be less than the material of piston material, therefore alleviate the weight of whole piston in guarantee on the premise of, piston can be supported and be unlikely to deform, so that it is guaranteed that properties of product.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment 1, as it is shown in figure 1, compressor rolling piston, cavity 21 is set including in, half piston 1, half piston 2, half piston 2, half piston 1 arranges cavity 11, is linked together by welding 3 between contact position inside and outside the axial biend 13,23 of half piston 2 and half piston 1.
Above-mentioned cavity 21 and cavity 11 are located on connecting end surface for annular and opening, and such half piston easily manufactures.
Embodiment 2, as in figure 2 it is shown, the outer shroud of half piston 2 connects also carries out interference connection 4 between end 23 and second half piston outer shroud connection end 13, remaining is with embodiment 1.
Interference connection 4 is also carried out between end 23 and second half piston 1 outer shroud connection end 13 owing to the outer shroud of half piston 2 connects, the most firm.
Embodiment 3, as it is shown on figure 3, the internal ring of half piston 2 connects also carries out interference connection 4 between end 23 and second half piston 1 internal ring connection end 13, remaining is with embodiment 1.
Embodiment 4, as shown in Figure 4, also carry out interference between internal ring connection end 23 and second half piston 1 internal ring connection end 13 of half piston 2 and connect 4, do not weld between internal ring connection end 23 and second half piston 1 internal ring connection end 13 of half piston 2, so on the premise of ensureing fixing intensity, it is possible to reduce operation.
Embodiment 5, as shown in Figure 5, also carrying out interference between outer shroud connection end 23 and second half piston outer shroud connection end 13 of half piston 2 and connect 4, also carry out interference connection 4 between internal ring connection end 23 and second half piston 1 internal ring connection end 13 of half piston 2, remaining is with embodiment 1.
Embodiment 6, as shown in Figure 6, arranges through hole 12 on half piston 1, arranges through hole 22 on half piston 2, through hole 22 filled up by resin 5 in the cavity of hollow cylinder, and remaining is with embodiment 3.
Certainly, it is possible in the cavity that by through hole 21 resin filled up hollow cylinder.The space casting resin 5 between half piston 1 and second half piston 2 can also be utilized.
