Description
Technical field
The utility model belongs to air compressor design manufacturing technology field, is related to a kind of crankcase of air compressor machine, especially
It is the lubrication system in a kind of air compressor crankcase.
Background technique
Air compressor abbreviation air compressor machine is a kind of equipment to compressed gas.Air compressor and water pump structure class,
Most of air compressors are using reciprocating-piston, rotating vane or rotary screw come compressed air, and air compressor machine presses working principle
It can be divided into three categories: displacement type, power type (velocity profile or turbine type), heating power type compressor.Positive displacement compressor be directly according to
The equipment for improving gas pressure by changing gas volume；Piston compressor is one kind of positive displacement compressor, compression member
Part is a piston, is moved reciprocatingly in cylinder.The crankshaft being mounted in crankcase is driven to generate rotary motion by motor,
And then drive connecting rod that piston is made to generate reciprocating motion, cause volume of cylinder to change.Due to the variation of inner pressure of air cylinder, pass through air inlet
Valve passes air through air cleaner (silencer) into cylinder, and in compression travel, due to the diminution of volume of cylinder, compression is empty
Gas passes through the effect of exhaust valve, and through exhaust pipe, check valve (check-valves) enters air accumulator, since crankshaft is transported at a high speed in crankcase
Turn, it is the important measures prolonged its service life that good lubrication is kept to it.
It is double that Chinese patent (notification number: CN201650671U, publication date: 2010-11-24) discloses a kind of automobile air compressor
Cylinder integral one-piece crankshaft box structure, the integral one-piece crankshaft box structure include cylinder body and crankcase, install crankshaft, cylinder in crankcase
Installation piston rod sub-assembly in vivo.Cylinder body is twin-tub, and the twin-tub and crankcase are integral type, and the bottom of crankcase is equipped with
The outer diameter of oil sealing mouth, twin-tub is equipped with reinforcing rib；Oil sealing mouth is arranged in crankcase bottom；Crankcase one end is equipped with connection engine
Positioning convex platform, the other end connects boring cover, and positioning convex platform is equipped with the venthole that is distributed in a ring.
There is no the specific lubrication system in open crankcase in above patent document, traditional lubricating system is usually in song
The a large amount of lubricating oil of injection, not only at high cost in axle box, and easily occurs the risk of oil leak in use for some time, due to
No specific aim is lubricated, lubricant effect is also bad.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, is proposed in a kind of air compressor crankcase
Lubrication system, the technical problem to be solved by the utility model is to how to reduce the leakage and promotion of lubricating oil in crankcase
Lubricant effect.
The purpose of this utility model can be realized by the following technical scheme:
A kind of lubrication system in air compressor crankcase, air compressor crankcase includes the shell with cavity, the shell
One end end face have and be connected to the through-hole of cavity, which is characterized in that there is boss, institute on the inside of the other end face of the shell
The middle part for stating boss has installation groove, and the lubrication system includes being provided with the oil filler point of housing top surface and being provided with shell bottom
The oil outlet in face further respectively has the oil inlet passage being connected to inside the oil filler point and the installation groove and company on the shell
Lead to the oil discharge passage inside the oil outlet and the installation groove；Oil seal ring is equipped in the installation groove at notch,
Annular groove is offered on the inner wall of the oil seal ring, passes through drainback passage phase between the annular groove and the oil discharge passage
Connection.
The principle is as follows: crankshaft installed is in the cavity of shell, and for installing bearing in installation groove, bearing is located at close
In the space of installation groove slot bottom, one end of crankshaft is mounted in installation groove by the bearing, and the outer ring of bearing and installation are recessed

Outside shell, and it is connected with driving motor, through hole also is provided with bearing and sealing structure.After installing crankshaft, so that bearing space
Closing, lubricating oil can be accommodated by installing in the space of bearing, inject lubricating oil to bearing space by oil filler point and oil inlet passage
Afterwards, lubricating oil plays the role of lubricating action to bearing, and oil seal ring plays lock oil, and most of lubricating oil is let out without going past oil seal ring
Dew, all lubricating oil are recycled by external oil circuit；Entire oil circulation system can be mentioned by compressor, blower etc.
For power；Since oil seal ring and crankshaft relatively rotate, there is gap between the two, least a portion of lubricating oil can permeate oil seal ring with
Flow out bearing space in gap between crankshaft, by the way that annular groove is arranged on oil seal ring inner wall in the technical program, so that stream
The lubricating oil for entering oil seal ring is blocked when passing through annular groove, and is flowed back into oil discharge passage by drainback passage, most
It also imports in oil circulation system eventually.This lubrication system only needs a small amount of lubricating oil, it will be able to which that shoots the arrow at the target is directed to bearing
It is lubricated, effectively reduces the leakage of greasing substance, and ensure that lubricant effect.
In the lubrication system in above-mentioned air compressor crankcase, the quantity of the annular groove is at least three and owns
Annular groove is evenly spaced on along the axial direction of oil seal ring, and the size of the annular groove is by oil seal ring close to installation groove slot bottom
One end gradually become smaller to close to one end of installation groove notch.Pass through the blocking reflux of multiple annular grooves in layer, energy
It is substantially prevented from outflow of lubrication oil, maximized circulation lubrication.
In the lubrication system in above-mentioned air compressor crankcase, there is several reinforcing ribs on the inner wall of the shell,
The oil inlet passage and oil discharge passage are arranged in the reinforcing rib.It can guarantee the intensity of crankcase in this way.
In the lubrication system in above-mentioned air compressor crankcase, the notch of the installation groove is towards the through-hole, institute
It states through-hole described in installation groove face and the two is coaxially disposed；The drainback passage is connected to the ring near installation groove notch
At connected in star slot bottom.
In the lubrication system in above-mentioned air compressor crankcase, the two sides side of the shell close to top all have by
The installation inclined-plane that side extends to top surface inclination, it is 90 ° that two installation inclined-planes, which are formed by angle, on each installation inclined-plane
A mounting hole is all had, two mounting holes are symmetric using the center line of boss as symmetry axis.The lateral surface of shell
Piston/cylinder is installed at mounting hole, piston/cylinder is fastened by bolts on installation inclined-plane, the intracorporal piston of piston cylinder
It is connected by piston rod and connecting rod with crankshaft, connecting rod passes through mounting hole.The above-mentioned design of mounting hole was both examined from space layout
Consider, and shell can be effectively reduced and reveal machine oil from mounting hole.
Compared with prior art, the lubrication system in the utility model only needs a small amount of lubricating oil, it will be able to which some is put
Being lubricated for bearing for arrow, effectively reduces the leakage of greasing substance, and ensure that lubricant effect.
