Abstract
The utility model discloses an oil free structured piston of a compressor. The oil free structured piston of the compressor comprises a piston body, wherein the piston body is made of cast aluminum material and comprises a first split body (1a) and a second split body (1b), the first split body (1a) and the second split body (1b) are connected into a whole through a pin (2), a compressed surface (3) of the piston is located on the first split body (1a), a first plastic support ring (4a) is arranged in the middle of the outer circle of the first split body (1a), a first piston ring (5a) and a second piston ring (5b) are arranged at intervals on the first split body (1a) and between the first plastic support ring (4a) and the second split body (1b), and a second plastic support ring (4b) is arranged on the outer circle, close to the first split body (1a), of the second split body (1b). The oil free structured piston of the compressor is suitable for an oil free large-piston compressor, simple to machine, and high in reliability.
Description
Technical field
The utility model relates to a kind of piston, particularly relate to a kind of for compressor without the large piston of oily structure.
Background technique
Generally be used for small piston without oily structure piston, but large piston, piston mass is larger, be difficult to satisfy than pressure request, and if alleviate piston weight, the rigidity of piston is difficult to again meet design requirement.
Therefore those skilled in the art be devoted to develop a kind of low specific pressure without the large piston of oily structure.
The model utility content
Because the defects of prior art, technical problem to be solved in the utility model be to provide a kind of use low specific pressure without the large piston of oily structure.
For achieving the above object, the utility model provides a kind of compressor without oily structure piston, comprises piston only, and described piston only is casting aluminium material, comprises the first split and the second split; Described the first split and the second split are connected to integral body by pin; The compressing surface of piston is positioned in described the first split; Be provided with the first plastic support ring in the middle part of the cylindrical of described the first split; Described the first split locates to be arranged at intervals with first piston ring and the second piston ring between described the first plastic support ring and described the second split; Described the second split is provided with the second plastic support ring near the cylindrical of described the first split place.
Better, the external diameter of described the first split is 757mm.
Better, the external diameter of described the first plastic support ring and the second plastic support ring is
Better, towards described the first split one side, described the second support ring is concordant with the end face of the second split.
Better, the spacing of described the first plastic support ring, first piston ring, the second piston ring and the second plastic support ring adjacent face is 15mm.
The beneficial effects of the utility model are: it is demanding without the large piston compressor of oil that the utility model can adapt to reduced pressure, and casting processing is simple, reliability is high.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of compressor comprises the piston only of cast aluminium without oily structure piston, and piston only comprises the first split 1a and the second split 1b, and the first split 1a and the second split 1b are connected to integral body by pin 2.The compressing surface 3 of piston is positioned on the first split 1a.
Be provided with the first plastic support ring 4a in the middle part of the cylindrical of the first split 1a, the first split 1a locates to be arranged at intervals with first piston ring 5a and the second piston ring 5b between the first plastic support ring 4a and the second split 1b, the second split 1b is provided with the second plastic support ring 4b near the cylindrical at the first split 1a place.Towards the first split 1a one side, the second support ring 4b is concordant with the end face of the second split 1b.
The external diameter φ 1 of the first split 1a is 757mm.The external diameter φ 2 of the first plastic support ring 4a and the second plastic support ring 4b is
The spacing of the first plastic support ring 4a, first piston ring 5a, the second piston ring 5b and the second plastic support ring 4b adjacent face is 15mm.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
