Abstract
The utility model discloses a kind of flange and casing connecting structure, and wherein said flange offers groove vertically, and described shell end embeds in described groove.Also disclose a kind of horizontal rotary compressor bearing support and to oil casing connecting structure, described bearing support has outside flange, and wherein, described flange offers groove vertically, described in the shell end that oils embed in described groove.Also disclose a kind of horizontal rotary compressor, it comprises above-mentioned horizontal rotary compressor bearing support and oils casing connecting structure.The utility model utilizes very simple structure, can ensure the close fit of flange and housing when local heating, is particularly useful for horizontal rotary compressor bearing support and the compact siro spinning technology of the housing that oils, improves its installation reliability.
Description
Technical field
The utility model relates to horizontal rotary compressor lubrication system, particularly relates to flange and casing connecting structure, horizontal rotary compressor bearing support and oil casing connecting structure and horizontal rotary compressor.
Background technique
The for the benefit of oil lubrication on compressor of existing horizontal rotary compressor, conventional technology adopts bearing support axle journal cylindrical to be assembled by interference fit with the housing inner circle that oils.Fig. 1 is the horizontal rotary compressor bearing support of prior art and the schematic diagram of the casing connecting structure that oils.As shown in Figure 1, the cylindrical of the axle journal (also claiming flange) of bearing support 10 and the inner circle interference fit of the housing 20 that oils, the close-fitting section of housing 20 of oiling is drawing part, wall thickness should not thicken, and due to wall thickness thinner, after having assembled, when local heating, due to bearing support 10 and the difference of housing 20 in material, thickness that oils, the two be heated after degrees of expansion difference to some extent, for the housing 20 that oils of thin-walled, its inner circle degrees of expansion is far longer than the axle journal cylindrical of the bearing support 10 of heavy wall, coming off of the housing 20 that so very easily causes oiling.
Model utility content
The object of the utility model embodiment is to provide a kind of flange and casing connecting structure, horizontal rotary compressor bearing support and the casing connecting structure that oils, the horizontal rotary compressor comprising above-mentioned linkage structure is also provided, makes to solve the interelement close fit problem that is connected in local heating's situation.
For solving the problems of the technologies described above, the utility model embodiment proposes a kind of flange and casing connecting structure, and described flange offers groove vertically, and described shell end embeds in described groove.
As preferably, described shell end periphery and described groove inner headed face interference fit.
The utility model embodiment also proposes a kind of horizontal rotary compressor bearing support and to oil casing connecting structure, and described bearing support has outside flange, and wherein, described flange offers groove vertically, described in the shell end that oils embed in described groove.
As preferably, described in oil shell end periphery and described groove inner headed face interference fit.
The utility model embodiment also proposes a kind of horizontal rotary compressor, comprises above-mentioned horizontal rotary compressor bearing support and oils casing connecting structure.
The utility model utilizes very simple structure, can ensure the close fit of flange and housing when local heating, is particularly useful for horizontal rotary compressor bearing support and the compact siro spinning technology of the housing that oils, improves its installation reliability.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
The utility model embodiment provides a kind of flange and casing connecting structure, and flange offers groove vertically, and shell end embeds in groove.When local heating, shell end degrees of expansion is larger than flange, utilizes this structure of the present utility model, and housing can be made more to be fixedly mounted in the groove of flange, improves installation reliability.
Wherein, shell end periphery can with groove inner headed face interference fit.Both connections can be made so more reliable.
The utility model embodiment still provides a kind of horizontal rotary compressor bearing support and oils casing connecting structure.Fig. 2 is the horizontal rotary compressor bearing support of the utility model embodiment and the schematic diagram of the casing connecting structure that oils, and Fig. 3 is the enlarged view of local in Fig. 2.As Figure 2-3, bearing support 1 has outside flange, and flange offers groove 3 vertically, and housing 2 end that oils embeds in groove 3.When local heating, the housing 2 end degrees of expansion that oils is larger than flange, utilizes this structure of the present utility model, and the housing 2 that can make to oil can be fixedly mounted in the groove 3 of flange more, improves installation reliability.Similarly, oil housing 2 end periphery can with the inner headed face interference fit of groove 3.
The utility model embodiment still provides a kind of horizontal rotary compressor, comprises above-mentioned horizontal rotary compressor bearing support and oils casing connecting structure.When horizontal rotary compressor comprises this linkage structure, its operation is more reliable.
Certainly, be more than preferred implementation of the present utility model, should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
