Abstract
Rolling piston for compressor, it includes interior cylinder, outer cylinder, connects the lid, connects the lid and sets up cylinder and/or outer cylindrical one -tenths cavity in the cavity inclusive AND, connects including fixed between two ends of cylinder and outer cylindrical and between being covered hollow cylinder of formation of lid by interior cylinder, outer cylinder, connection. The utility model discloses because the holding surface of connecting between lid and interior, the outer cylinder is great, consequently connect the lid internally, outer cylinder's holding power increases, especially the holding power to piston center part increases, consequently the utility model discloses in the basis that alleviates whole piston weight go up to make, the outer cylinder homoenergetic enough obtains the support and non -deformable to ensure to produce the property ability.
Description
Technical field
This utility model 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 hollow cylinder in use can deform, therefore can affect its serviceability.
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 not only alleviate weight and can ensure that serviceability.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
Compressor rolling piston, including interior cylinder, outside cylinder, connection lid, connect lid arrange cavity or form cavity with interior cylinder and/or outside cylinder, connect lid and be fixed between interior cylinder and two ends of outside cylinder by forming a hollow cylinder between interior cylinder, outside cylinder, connection lid.
Preferably, above-mentioned connection lid is divided into upper cover and lower cover two part, upper cover and lower cover are separately fixed between interior cylinder and two ends of outside cylinder by forming a hollow cylinder between interior cylinder, outside cylinder, upper cover and lower cover, upper cover and/or lower cover arrange cavity or and interior cylinder and/or outside cylinder between formed cavity.
Preferably, upper cover and/or lower cover section are essentially U type or the type of falling U, and such upper cover, lower cover are more easily manufactured and can preferably support outside cylinder or interior cylinder by a spike for U-shaped two sides.
Preferably, two ends of the outer surface of above-mentioned interior cylinder are respectively provided with outer spacing, and upper cover and lower cover are respectively by outer spacing, and such upper cover and lower cover can preferably position, and prevent upper cover and lower cover to be pressed into deep.
Preferably, two ends of the inner surface of above-mentioned outside cylinder are respectively provided with interior spacing, and upper cover and lower cover are respectively by interior spacing, and such upper cover and lower cover can preferably position, and prevent upper cover and lower cover to be pressed into deep.
Preferably, above-mentioned upper cover and lower cover are that interference is connected or welds with interior cylinder and outside cylinder respectively, so fixing more firm, seal more preferably.
Compared with prior art, the utility model has the advantage of: bigger owing to connecting the supporting surface between lid and inside and outside cylinder, therefore connect lid support force internal, exterior circular column to increase, particularly the support force at piston centre position is increased, therefore this utility model makes inside and outside cylinder all can be supported and be unlikely to deform on the basis of alleviating whole piston weight, so that it is guaranteed that properties of product.
Accompanying drawing explanation
Fig. 1 is the configuration diagram of this utility model embodiment rolling piston.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the structural representation of another embodiment rolling piston of this utility model.
Fig. 4 is the B-B profile of 3.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Embodiment 1, as shown in Figure 1 and Figure 2, compressor rolling piston, is respectively pressed between interior cylinder 2 and the biend of outside cylinder 1 by forming a hollow 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.
Arranging cavity 31 in the middle of above-mentioned upper cover 3, cross section is essentially inverted U, and it can reduce the weight of upper cover 3, and the spike further through U-shaped two sides can preferably support outside cylinder.
In like manner, lower cover 4 arranges cavity 41, also can reduce the weight of lower cover 4.
But owing to the spacing of upper cover 3 and lower cover 4 is less, therefore, upper cover 3 and lower cover 4 have preferably support to the outside cylinder 1 of rolling piston, and therefore the outside cylinder 1 of rolling piston is unlikely to deform.
On the outer surface of above-mentioned interior cylinder 2, two ends are respectively provided with outer spacing 21, and upper cover 3 and lower cover 4 are respectively by outer spacing 21 spacing, and therefore upper cover 3 and lower cover 4 are installed more convenient.
Embodiment 2, by the most U-shaped for the cross section of the upper cover 3 in embodiment 1 and lower cover 4, remaining is identical with embodiment 1, sees Fig. 3, Fig. 4.
Above-mentioned upper cover, lower cover can be different titles according to angle when manufacturing or the difference of viewing angle, such as left cover, right cover, its essence is and refer to identical object.
Certainly upper cover 3, lower cover 4 cross section can be also L-type, although its only two, but also form cavity between itself and interior cylinder 2, outside cylinder 1, therefore belong to the concrete manifestation form of upper cover 3, lower cover 4, each fall within protection domain of the present utility model.
Above-mentioned upper cover 3, lower cover 4 cross section can be also other shapes, as long as meeting the technical characteristic of claim, all protected by this utility model.
