Below with reference to Fig. 1-Fig. 7, the bent axle 100 for piston compressor 1000 according to embodiments of the present invention is described.
As shown in Figure 4 and Figure 5, piston compressor 1000 includes connecting rod 200 and one end (the i.e. Fig. 4 being connected to connecting rod 200
The right-hand member of shown connecting rod 200) piston 300, the other end (i.e. the left end of the connecting rod 200 shown in Fig. 4) of connecting rod 200 is suitable to cover
It is located on bent axle 100, connecting rod 200 can play the effect connecting piston 300 and bent axle 100, such that it is able to by the rotation of bent axle 100
The dynamic linear reciprocating motion being converted into piston 300 of transhipment is for the gas in compression cylinder.
Bent axle 100 for piston compressor 1000 according to embodiments of the present invention can include body 10.As Fig. 1 institute
Show, body 10 includes long shaft part 20 and the gearratio of cycloid axle formation being located at long shaft part 20 one end (i.e. the upper end of the long shaft part 20 shown in Fig. 1)
30, the side wall of gearratio of cycloid axle formation 30 is formed with out oil groove 40, goes out oil groove 40 not through gearratio of cycloid axle formation 30 away from long shaft part 20
End face (i.e. the upper surface of the gearratio of cycloid axle formation 30 shown in Fig. 1), gearratio of cycloid axle formation 30 is formed with oil outlet 50, one end of oil outlet 50
Run through the upper surface of gearratio of cycloid axle formation 30, oil outlet 50 is connected with going out oil groove 40.
As shown in figure 1, being provided with crank 90 between long shaft part 20 and gearratio of cycloid axle formation 30, gearratio of cycloid axle formation 30 is eccentrically arranged in song
On handle 90.Alternatively, go out oil groove 40 and can be configured to axial direction (i.e. above-below direction shown in Fig. 1) inclination along gearratio of cycloid axle formation 30
Extend, tilt extend go out oil groove 40 and can be conducive to the lubrication between gearratio of cycloid axle formation 30 and the left end of connecting rod 200.
As shown in Figure 4 and Figure 5, the other end (i.e. the left end of the connecting rod 200 shown in Fig. 4) of connecting rod 200 is suitable to be set in partially
On heart shaft part 30, and the left end of connecting rod 200 closes out oil groove 40, and the lubricating oil being thrown away from oil outlet 50 is suitable to get rid of to piston
300.That is, in piston compressor 1000 operation process, the left end of connecting rod 200 closes out oil groove 40, it is possible to reduce
Go out the oil mass that oil groove 40 throws away, such that it is able to reduce the oil pump capacity oil groove 40.Can be used by going out the lubricating oil that oil groove 40 throws away
To lubricate the contact surface of the left end of gearratio of cycloid axle formation 30 and connecting rod 200, so that connecting rod 200 and bent axle 100 stable connection
And long service life.Specifically, the lower end going out oil groove 40 is connected with oil outlet 50, thereby may be ensured that out oil groove 40 preferably
Lubricate oil groove 40 and the contact surface of connecting rod 50.In addition, the lubricating oil that oil outlet 50 throws away can get rid of to piston 300, thus right
Contact surface between piston 300 and cylinder plays lubrication it is ensured that normal work in cylinder for the piston 300.
Thus, the bent axle 100 for piston compressor 1000 according to embodiments of the present invention, can improve piston type pressure
The oil pump capacity of contracting machine 1000, and the contact surface between piston 300 and cylinder can be played with lubrication, reduce piston 300
Friction and cylinder between, further can reduce the caloric value of piston compressor 1000.
In some examples of the present invention, in conjunction with shown in Fig. 1, Fig. 4 and Fig. 5, for the bent axle of piston compressor 1000
100 can further include：Fuel-displaced pin 60, fuel-displaced pin 60 can be located in oil outlet 50, and fuel-displaced pin 60 is positioned at fuel-displaced
The one end (i.e. the upper end of the oil outlet 50 shown in Fig. 4) in hole 50, has fuel-displaced with what oil outlet 50 inside connected in fuel-displaced pin 60
Passage 61.That is, after the lubricating oil that long shaft part 20 flows to oil outlet 50 enters oil outlet 50, then by fuel-displaced pin 60
Oil discharge passage 61 throws away oil outlet 50.It is understood that because fuel-displaced pin 60 is arranged in oil outlet 50, so oil discharge passage
61 internal diameter is less than the internal diameter of oil outlet 50, thus, by arranging fuel-displaced pin 60, at least can reduce piston type to a certain extent
The oil pump capacity of compressor 1000.Alternatively, fuel-displaced pin 60 can be resilient key.
Alternatively, as shown in Figures 2 and 3, one end end face away from long shaft part 20 of fuel-displaced pin 60 could be formed with court
The breach 70 opening wide to the central axial direction of long shaft part 20.By being provided with breach 70 on fuel-displaced pin 60, can improve fuel-displaced
Pressure in hole 50 so that the lubricating oil throwing away from breach 70 throw away higher to get rid of the bottom into piston 300, from
And the effect of lubrication piston 300 and cylinder can be played.And in piston compressor 1000 operation process, got rid of by breach 70
The lubricating oil going out intermittently gets rid of the bottom into piston 300.For example, as shown in fig. 6, A as breach 70 in region gets rid of into piston 300
Bottom rotational coverage, now piston compressor 1000 may be at exhaust condition.Alternatively, fuel-displaced pin 60 with go out
Oilhole 50 can be with interference fit, and the fuel-displaced pin 60 of interference fit and oil outlet 50 cooperation are stable.
As a kind of optional embodiment, as shown in fig. 7, oil outlet 50 can include (i.e. upper shown in Fig. 7 vertically
Lower direction) the first connected oil outlet 80 and the second oil outlet 81, the cross-sectional area of the first oil outlet 80 is less than the second oil outlet
81 cross-sectional area, the free end (i.e. the upper end of the first oil outlet 80) of the first oil outlet 80 run through gearratio of cycloid axle formation 30 away from length
The end face of shaft part 20.Lubricating oil in entrance oil outlet 50 first passes through the second oil outlet 81 and is thrown away by the first oil outlet 80, by
In the first oil outlet 80 cross-sectional area be less than the second oil outlet 81 cross-sectional area, such that it is able to further increase oil outlet
Pressure in 50, so the lubricating oil throwing away from the first oil outlet 80 throw away higher.
Alternatively, oil outlet 50 can be circular port, slotted eye, Long Circle hole or polygonal hole.May be appreciated
It is that, when oil outlet 50 is circular port, fuel-displaced pin 60 can be for circular port in order to coordinate with oil outlet 50.That is, going out
The shape of oily pin 60 adaptively can be selected according to the shape of oil outlet 50.
The piston compressor 1000 of embodiment according to a further aspect of the invention, including above-described embodiment for piston type
The bent axle 100 of compressor 1000.Have above-described embodiment the bent axle 100 for piston compressor 1000 piston type compressed
Machine 1000 can improve oil pump capacity, and can lubricate piston 300 and cylinder, thus caloric value can reduce.
