Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings.Below with reference to
The embodiment that accompanying drawing describes is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to of the present utility model
Limit.
Below with reference to the accompanying drawings the compressor crank shaft 100 according to this utility model embodiment is described in detail.
Compressor crank shaft 100 according to this utility model embodiment may include that main shaft 10, balance weight 20 and eccentric shaft 30,
Balance weight 20 is between main shaft 10 and eccentric shaft 30, and bent axle 100 can be formed in one part.And as it is shown in figure 1,
Eccentric shaft 30 relative main 10 eccentric setting, the periphery of main shaft 10 is provided with oil groove 11, and the lower end of main shaft 10 is provided with
Fuel feed hole 12, fuel feed hole 12 is connected with oil groove 11, and eccentric shaft 30 is provided with oil outlet 31, main shaft 10 and balance weight
Being provided with the first oil circuit 40 on 20, the first oil circuit 40 is arranged in the periphery of main shaft 10, and the first oil circuit 40 and oil groove 11
Being connected, the first oil circuit 40 also extends upward through balance weight 20 and is connected with oil outlet 31.
Wherein, as it is shown in figure 1, the side of the close main shaft 10 of balance weight 20 is crankshaft thrust face 21, crankshaft thrust face 21
The most only can support with the crankcase thrust surface of crankcase.Under the effect of oil pump, lubricating oil can enter into from fuel feed hole 12
In the whole oil duct of bent axle 100, under the influence of centrifugal force, lubricating oil can enter in oil groove 11, and lubricating oil can
To be flowed in the first oil circuit 40 by oil groove 11, it is arranged on the upper end of the periphery of main shaft 10 due to the first oil circuit 40, i.e.
First oil circuit 40 flows through crankshaft thrust face 21, and a part of lubricating oil in the first oil circuit 40 can lubricate crankshaft thrust face 21
With crankcase thrust surface, another part lubricating oil in the first oil circuit 40 can be upward through balance weight 20 after by eccentric shaft
Oil outlet 31 on 30 throws away.
Thus, according to the compressor crank shaft 100 of this utility model embodiment, by arranging the first oil circuit 40, on bent axle 100
Lubricating oil can flow to crankshaft thrust face 21 and crankcase thrust surface, such that it is able to two thrust surfaces of effectively lubricating, can subtract
Abrasion between slow two thrust surfaces, can improve the service life of compressor, can reduce the noise of compressor.
According to a preferred embodiment of the present utility model, as it is shown in figure 1, the first oil circuit 40 may include that main shaft oil circuit 41
With balance weight oil circuit 42, main shaft oil circuit 41 vertically extends on main shaft 10, and balance weight oil circuit 42 is vertical in balance weight 20
Extend.In other words, main shaft oil circuit 41 is connected to the part between balance weight oil circuit 42 and oil groove 11, in main shaft oil circuit 41
Lubricating oil can flow to two thrust surfaces to lubricate this two thrust surfaces.The main shaft oil circuit 41 vertically extended can keep quantitative
Lubricating oil flows to two thrust surfaces, such that it is able to two thrust surfaces of effectively lubricating.
Alternatively, as it is shown in figure 1, the junction of the first oil circuit 40 and oil groove 11 can be arranged on the underface of eccentric shaft 30.
Thus, the first oil circuit 40 can upwards be connected with oil outlet 31, so that the first oil circuit 40 simple in construction, and cloth
Put conveniently, the production difficulty of bent axle 100 can be reduced.
According to a preferred embodiment of the present utility model, as it is shown in figure 1, be formed on crankshaft thrust face 21 around main shaft 10
Groove 22, groove 22 connects with the first oil circuit 40.Thus, parts of lubricating oil can be stored in groove 22, thus
When compressor just starts, it is stored in the lubricating oil in oil groove 11 and can lubricate two thrust surfaces, and then two can be promoted only
Lubricant effect between pushing surface, can extend the service life of compressor.
Alternatively, the rotation direction of oil groove 11 is contrary with the direction of rotation of main shaft 10.Such as, when main shaft 10 turns clockwise, oil
The rotation direction of groove 11 is counterclockwise.Thus, under the influence of centrifugal force, lubricating oil is prone to flow from bottom to top in oil groove 11,
Such that it is able to improve lubricating oil flowing smoothness in oil groove 11.
According to a specific embodiment of the present utility model, connect between fuel feed hole 12 and oil groove 11 and have the second oil circuit, second
Oil circuit is obliquely installed.Second oil circuit is formed in main shaft 10, and the second oil circuit being obliquely installed is so that lubricating oil within it flows
Smooth and easy, the pump oil efficiency of bent axle 100 can be improved.Preferably, the central axis of the second oil circuit can be with in relative main 10
Heart axis bias 1mm-2mm.The second oil circuit meeting above-mentioned scope can reduce by second oil circuit shadow to main shaft 10 structural strength
Ring, it can also be ensured that the flowing smoothness of lubricating oil in the second oil circuit.
Alternatively, as it is shown in figure 1, compressor crank shaft 100 can also include: venting through hole 13, through hole 13 and second of exitting
Oil circuit is connected, and through hole 13 radially extending along main shaft 10 of exitting.It is understood that the gas in the second oil circuit can
To be discharged by venting through hole 13, such that it is able to avoid gas to continue up, the flowing smoothness of lubricating oil can be improved,
The lubricant effect of compressor crank shaft 100 can be improved.Preferably, venting through hole 13 can be arranged adjacent to the lower end of main shaft 10.
According to the compressor of this utility model embodiment, including: the compressor crank shaft 100 of above-described embodiment, due to above-mentioned enforcement
Arrange on main shaft 10 periphery of the compressor crank shaft 100 of example by the first oil circuit 40, so that the lubricating oil on bent axle 100
Flow to crankshaft thrust face 21 and crankcase thrust surface, such that it is able to two thrust surfaces of effectively lubricating, two thrust surfaces can be slowed down
Between abrasion, the service life of compressor can be improved, the noise of compressor can be reduced.
