Abstract
The invention discloses a horizontal rotor compressor which comprises a pump body. The pump body comprises a supplementary bearing and an oil suction cover; an inner hole is formed in a body annular wall of the supplementary bearing; an oil suction cover installing annular wall is arranged on the periphery of the body annular wall of the supplementary bearing; an end face annular groove is formed between the body annular wall and the oil suction cover installing annular wall; the oil suction cover is installed on the outer surface of the oil suction cover installing annular wall in an interference mode. According to the horizontal rotor compressor, the end face annular groove is formed in the end face of the supplementary bearing used for installing the oil suction cover, and the oil suction cover is installed on the outer surface of the oil suction cover installing annular wall on the periphery of the end face annular groove in an interference mode; even if the interference degree between the oil suction cover installing annular wall and the inner circle of the oil suction cover which is matched with the oil suction cover installing annular wall is from 0.05 mm to 0.15 mm or slightly larger than 0.15 mm, due to the existence of the oil suction cover installing annular wall, the deformation caused by indentation force generated by interference fit between the oil suction cover installing annular wall and the inner circle of the oil suction cover can be effectively absorbed, and the influences on the dimension and circular degree of the inner hole in the supplementary bearing are so small that the influences can be ignored.

[background technique]
Refer to shown in Fig. 1, existing horizontal rotor compressor, be made up of the pump housing 1, drive motor 2, housing 3; Its middle pump body 1 formed primarily of main bearing 1-1, supplementary bearing 1-2, rotary piston 1-3, bent axle 1-4, blotter cover 1-5, cylinder 1-6, the assembling relationship figure of blotter cover 1-5 and supplementary bearing 1-2 as shown in Figure 2, the inner circle 1-5-1 of blotter cover 1-5 and the periphery 1-2-3 interference fit of supplementary bearing 1-2, during for ensureing compressor operation, do not make it throw off because of vibration, this part coordinates interference all at 0.05 ~ 0.15mm, even larger.What interference fit was formed inside contract power makes the circularity of the endoporus 1-2-4 of supplementary bearing 1-2 be deteriorated, and internal diameter size diminishes, and have impact on the formation of bearing film, and then causes the diameter of axle to hold axle to lose efficacy.
[summary of the invention]
The object of the present invention is to provide a kind of horizontal rotor compressor, to solve the problems of the technologies described above.
To achieve these goals, the present invention adopts following technological scheme:
A kind of horizontal rotor compressor, comprises the pump housing; The pump housing comprises supplementary bearing and blotter cover; The main body annular wall center of supplementary bearing is provided with endoporus; The periphery of the main body annular wall of supplementary bearing is provided with blotter cover and installs annular wall, and main body annular wall and blotter cover are installed between annular wall and formed an end face circular groove; Blotter cover interference is arranged on blotter cover and installs annular wall outer surface.
The present invention further improves and is: the degree of depth of end face circular groove is greater than the length that blotter cover and blotter cover install annular wall interference fit.
The present invention further improves and is: blotter cover installs the wall thickness δ=1 ~ 3mm of annular wall.
The present invention further improves and is: the magnitude of interference that blotter cover and blotter cover install annular wall is 0.05 ~ 0.15mm.
The present invention further improves and is: the described pump housing also comprises main bearing, rotary piston, bent axle and cylinder; Main bearing and supplementary bearing are arranged at cylinder both sides respectively; Rotary piston is arranged in cylinder; Supplementary bearing coordinates with the short shaft diameter of bent axle, and main bearing coordinates with the major axis footpath of bent axle, and rotary piston coordinates with the eccentric diameter of axle of bent axle; Short shaft diameter, the eccentric diameter of axle, major axis footpath connect successively.
The present invention further improves and is: described horizontal rotor compressor also comprises drive motor and housing; The pump housing and drive motor are arranged in housing; Drive motor is arranged at periphery, major axis footpath.
Relative to prior art, the present invention has following beneficial effect:
A kind of horizontal rotor compressor of the present invention, the supplementary bearing end face installing blotter cover has an end face annular groove, and the blotter cover that blotter cover interference is arranged on end face annular groove periphery installs annular wall outer surface; Even if blotter cover installs interference degree between annular wall and the inner circle of blotter cover matched at 0.05 ~ 0.15mm, or time slightly large again, because blotter cover installs the existence of annular wall, effectively can absorb the distortion brought with the power that inside contracts formed during blotter cover inner circle interference fit, the impact that the size of the endoporus of supplementary bearing and circularity are subject to becomes minimum, reaches negligible degree.

Fig. 2 is that existing horizontal compressor blotter cover and supplementary bearing assemble schematic diagram;
Fig. 3 is horizontal rotor compressor longitudinal sectional drawing of the present invention;
Fig. 4 is the assembling schematic diagram of horizontal rotor compressor blotter cover of the present invention and supplementary bearing.
In figure: 1, the pump housing; 1-1, main bearing; 1-2, supplementary bearing; 1-2-0, main body annular wall; 1-2-1, end face; 1-2-2, end face circular groove; 1-2-3, blotter cover install annular wall; 1-2-4, endoporus; 1-3, rotary piston; 1-4, bent axle; 1-5, blotter cover; 1-5-1, inner circle; 1-6, cylinder.
[embodiment]
Refer to shown in Fig. 3 and Fig. 4, a kind of horizontal rotor compressor of the present invention, comprises the pump housing 1, drive motor 2 and housing 3; The pump housing 1 and drive motor 2 are arranged in housing 3; The pump housing 1 formed primarily of main bearing 1-1, supplementary bearing 1-2, rotary piston 1-3, bent axle 1-4, blotter cover 1-5, cylinder 1-6.
Main bearing 1-1 and supplementary bearing 1-2 is arranged at cylinder 1-6 both sides respectively; Rotary piston 1-3 is arranged in cylinder 1-6; Supplementary bearing 1-2 coordinates with the short shaft diameter of bent axle 1-4, and main bearing 1-1 coordinates with the major axis footpath of bent axle 1-4, and rotary piston 1-3 coordinates with the eccentric diameter of axle of bent axle 1-4.Short shaft diameter, the eccentric diameter of axle, major axis footpath connect successively.Drive motor 2 is arranged at periphery, major axis footpath.
