As shown in Figure 2, blotter cover 1-5 inner circle 1-5-1's and supplementary bearing 1-2 is outer for oil cover 1-5 and supplementary bearing 1-2 assembling relationship figure
Disc 1-2-3 is interference fitted, and to ensure during compressor operation, to disengage it because of vibration, the part coordinates interference to exist
0.05~0.15mm, even more greatly.Being interference fitted the power that inside contracts formed makes supplementary bearing 1-2 endoporus 1-2-4 circularity be deteriorated,
Internal diameter size diminishes, and have impact on the formation of bearing film, in turn results in the diameter of axle and holds axle failure.
【The content of the invention】
It is an object of the invention to provide a kind of horizontal rotor compressor, to solve above-mentioned technical problem.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of horizontal rotor compressor, including the pump housing；The pump housing includes supplementary bearing and blotter cover；The main body annular wall of supplementary bearing
Center is provided with endoporus；Annular wall, main body annular wall and blotter cover are installed provided with blotter cover in the periphery of the main body annular wall of supplementary bearing
One end face annular groove of formation between annular wall is installed；Blotter cover interference is arranged on blotter cover and installs annular wall outer surface.
Further improve of the invention is：The depth of end face annular groove is more than blotter cover and installs annular wall mistake with blotter cover
It is full of the length of cooperation.
Further improve of the invention is：Blotter cover installs wall thickness δ=1~3mm of annular wall.
Further improve of the invention is：Blotter cover and blotter cover install the magnitude of interference of annular wall for 0.05~
0.15mm。
Further improve of the invention is：The pump housing also includes base bearing, rotary piston, bent axle and cylinder；Main shaft
Hold and be respectively arranged at cylinder both sides with supplementary bearing；Rotary piston is arranged in cylinder；The short shaft diameter of supplementary bearing and bent axle coordinates, main
The long diameter of axle of bearing and bent axle coordinates, and the eccentric diameter of axle of rotary piston and bent axle coordinates；Short shaft diameter, the eccentric diameter of axle, the long diameter of axle according to
Secondary connection.
Further improve of the invention is：The horizontal rotor compressor also includes motor and housing；The pump housing and
Motor is arranged in housing；Motor is arranged at long diameter of axle periphery.
Relative to prior art, the invention has the advantages that：
A kind of horizontal rotor compressor of the present invention, has an end face annular groove on the supplementary bearing end face for installing blotter cover, inhales
The blotter cover that oily cover interference is arranged on end face annular groove periphery installs annular wall outer surface；Even if blotter cover installs annular wall with matching
Blotter cover inner circle between interference degree in 0.05~0.15mm, or when slightly larger again, because blotter cover installs depositing for annular wall
The deformation that power is brought that inside contracts formed when being interference fitted with blotter cover inner circle can be effectively absorbed, is making the endoporus of supplementary bearing
Size and circularity by being influenceed to be changed into minimum, reach negligible degree.

【Embodiment】
Refer to shown in Fig. 3 and Fig. 4, a kind of horizontal rotor compressor of the present invention, including the pump housing 1, motor 2 and housing
3；The pump housing 1 and motor 2 are arranged in housing 3；The pump housing 1 is main by base bearing 1-1, supplementary bearing 1-2, rotary piston 1-3, song
Axle 1-4, blotter cover 1-5, cylinder 1-6 are constituted.
Base bearing 1-1 and supplementary bearing 1-2 are respectively arranged at cylinder 1-6 both sides；Rotary piston 1-3 is arranged in cylinder 1-6；
Supplementary bearing 1-2 and bent axle 1-4 short shaft diameter coordinates, and the base bearing 1-1 and bent axle 1-4 long diameter of axle coordinates, rotary piston 1-3 and song
