Abstract

Rolling piston for compressor is including interior cylinder, outer cylinder, upper cover and lower cover, between the cylinder was held with outer cylindrical no. 2 in upper cover and lower cover were impressed respectively and by cylinder of formation between interior cylinder, outer cylinder, upper cover and the lower cover. The utility model discloses since be hollow between rolling piston for compressor's interior cylinder and the outer cylinder, the light in weight of whole piston, so the drive ratio is more convenient, can the volume of saving energy saving to it is convenient to make.

Description

Compressor rolling piston

Technical field

This utility model relates to a kind of compressor part and manufacture method thereof.

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 outer ring 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.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art to provide a kind of compressor rolling piston so that it is can alleviate weight, thus reduce energy consumption.

This utility model additionally provides the manufacture method of a kind of compressor rolling piston, makes rolling piston be simple to manufacture, low cost and free from environmental pollution.

The technical scheme that the above-mentioned technical problem of this utility model solution is used is:

Compressor rolling piston, is respectively pressed between interior cylinder and two ends of outside cylinder by forming a cylinder between interior cylinder, outside cylinder, upper cover and lower cover including interior cylinder, outside cylinder, upper cover and lower cover, upper cover and lower cover.

Preferably, two ends of the outer surface of above-mentioned interior cylinder arrange outer stop bit, two ends of the inner surface of outside cylinder are respectively provided with interior stop bit, upper cover and lower cover are respectively pressed at the interior stop bit of the outer stop bit of interior cylinder two end, outside cylinder two end, so upper cover and lower cover can preferably position, and prevents upper cover and lower cover to be pressed into deep.

Accordingly providing the manufacture method of a kind of rolling piston, it comprises the steps:

(1) interior cylinder, outside cylinder, upper cover and the lower cover of required size, are prepared respectively；

(2), cylinder, outside cylinder, upper cover and lower cover in heat treatment；

(3), cylinder, outside cylinder, upper cover and lower exterior surface in corase grind；

(4), again upper cover, lower cover are respectively pressed between interior cylinder and outside cylinder；

(5) each face, is refined to reaching regulation requirement.

As stated above, so that it may produce qualified rotary compressor for refrigerant rolling piston.

Compared with prior art, the utility model has the advantage of:

1, owing to being hollow between inner cylinder and the exterior circular column of compressor rolling piston, the most whole piston lightweight, therefore drive more convenient, energy can be saved.

2, by arranging inner cylinder and exterior circular column, upper cover and lower cover being pressed into, it is easily manufactured.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

As shown in Figure 1 and Figure 2, compressor rolling piston, it is respectively pressed between interior cylinder 2 and the biend of outside cylinder 1 by forming a cylinder sealed between interior cylinder, outside cylinder, upper cover and lower cover including interior cylinder 2, outside cylinder 1, upper cover 3 and lower cover 4, upper cover 3 and lower cover 4.

In another embodiment, on outer surface two end of interior cylinder 2, outer stop bit 21 is set, on inner surface two end of outside cylinder, interior stop bit 11, upper cover 3 and lower cover 4 are set and are respectively pressed between interior cylinder 2 and the biend of outside cylinder 1 spacing by outer stop bit 21 and interior stop bit 11, see Fig. 3, Fig. 4.

The manufacture method of rotary compressor for refrigerant rolling piston, it comprises the steps:

(5) each face, is refined to reaching regulation requirement.

For preferably upper cover, lower cover being respectively pressed between interior cylinder and outside cylinder, the present embodiment has selected upper mold 5 and lower mold 6, upper cover, lower cover is respectively pressed between interior cylinder and outside cylinder by molding.

Certainly can also pass through additive method, upper cover, lower cover are respectively pressed between interior cylinder and outside cylinder.
