Abstract
The utility model relates to a kind of exhaust structures of compressor, including rotary compressor shell, rotary compressor shell is enclosure space, it is internally provided with eccentric shaft, the lower section of eccentric shaft is disposed with upper bearing (metal), cylinder and lower bearing from top to bottom, upper bearing (metal) includes upper bearing (metal) outer diameter, positioned at the outside of eccentric shaft, noise reduction lid is provided on the outside of upper bearing (metal) outer diameter, noise reduction lid is connect by bolt mode with upper bearing (metal), noise reduction lid is internally provided with noise reduction lid internal diameter, is provided with gap between noise reduction lid internal diameter and upper bearing (metal) outer diameter；Advantage is that the exhaust pathway of gas after changing changes, and is exhausted by the gap of noise reduction lid internal diameter and bearing outside diameter.It eliminates and covers the exhaust channel of aperture or other shapes in noise reduction, reduce manufacturing procedure, saved cost.
Description
Technical field
The utility model relates to compressor field, specifically a kind of exhaust structure of compressor.
Background technique
The structure of compressor is that the exhaust channel in hole or other shapes that gas is covered by noise reduction is discharged at present.Noise reduction
The internal diameter and upper bearing (metal) outer diameter of lid are contacts.On the one hand such structure is easy in compressor rotation in the place of contact
The exhaust channel of gas leakage, such noise reduction lid changes, and cannot play the role of good reduction gas noise.Another aspect noise reduction lid
Bolt mode and cylinder locking are used by bolt hole, when compressor rotation, noise reduction lid and upper bearing (metal) contact portion are easy to produce
Raw impact noise.
Utility model content
The purpose of the utility model is to provide a kind of exhaust structure of compressor, solves the noise reduction when compressor rotation
The problem of lid and upper bearing (metal) contact portion are easy to produce impact noise.
In order to achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of exhaust structure of compressor, including rotation
Rotary compressor shell, is characterized in that: rotary compressor shell is enclosure space, is internally provided with eccentric shaft, eccentric
The lower section of axis is disposed with upper bearing (metal), cylinder and lower bearing from top to bottom, and upper bearing (metal) includes upper bearing (metal) outer diameter, is located at bias
The outside of axis is provided with noise reduction lid on the outside of upper bearing (metal) outer diameter, and noise reduction lid is connect by bolt mode with upper bearing (metal), noise reduction lid
It is internally provided with noise reduction lid internal diameter, gap is provided between noise reduction lid internal diameter and upper bearing (metal) outer diameter, 5- is arranged in the size in gap
10mm。
The advantages of the utility model and beneficial effect are: the exhaust pathway of gas changes after change, passes through noise reduction lid
The gap of internal diameter and bearing outside diameter is exhausted.It eliminates and covers the exhaust channel of aperture or other shapes in noise reduction, reduce
Manufacturing procedure, has saved cost.Since noise reduction lid internal diameter and upper bearing (metal) outer diameter are clearance fits, compressor is avoided
The possibility of noise reduction lid and upper bearing (metal) impact noise occurs when operating.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of original noise reduction lid；
Appended drawing reference is as follows: 100, shell 200, cylinder 300, upper bearing (metal) 400, lower bearing 500, eccentric shaft
600, noise reduction lid 601, noise reduction lid internal diameter 602, aperture 603, bolt hole.
Specific embodiment
As shown in Figs. 1-2, the utility model relates to a kind of exhaust structures of compressor, including rotary compressor shell
100, in which: rotary compressor shell is enclosure space, is internally provided with eccentric shaft 500, the lower section of eccentric shaft is from top to bottom
It is disposed with upper bearing (metal) 300, cylinder 200 and lower bearing 400, upper bearing (metal) includes upper bearing (metal) outer diameter, positioned at the outer of eccentric shaft
Side is provided with noise reduction lid 600 on the outside of upper bearing (metal) outer diameter, and noise reduction lid is connect by bolt mode with upper bearing (metal), in noise reduction lid
Portion is provided with noise reduction lid internal diameter 601, and gap is provided between noise reduction lid internal diameter and upper bearing (metal) outer diameter, and 5- is arranged in the size in gap
10mm.Working principle is as follows: it is enclosure space inside rotary compressor shell 100, when eccentric shaft 500 rotates, and low pressure gas
Body is compressed into high pressure gas in the compression chamber that cylinder 200, upper bearing (metal) 300 and lower bearing 400 are formed.High pressure gas passes through
Noise reduction lid 600 is discharged to compressor inner space.Noise reduction, which covers, is provided with bolt hole 603, for passing through bolt mode and upper axis
It holds and is connected with cylinder locking；Noise reduction lid after optimization cancels aperture 602 in the plane, but increasing noise reduction lid internal diameter 601 makes
It obtains and forms gap between noise reduction lid internal diameter and upper bearing (metal) outer diameter 301.Compressed high pressure gas is discharged to compressor by gap
It is internal.
