Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
In engine cylinder as shown in Figures 1 to 6 dial oil lubrication mechanism, including piston cylinder 4 and inner casing, piston cylinder 4 with it is interior
Cylinder connects, and piston 2 is equipped in piston cylinder 4, and inner casing is equipped with connecting rod 1 and crank axle 3, and connecting rod 1 includes shaft end 11 and plug end 12, shaft end
11 connecting crank axis 3, plug end 12 connect piston 2；Inner casing is filled with lubricating oil, and the shaft end 11 of connecting rod 1 is towards under lubricating oil liquid level
Side, which is equipped with, dials oily part 10, dials 1 surface of connecting rod that oily part 10 is fixed on shaft end 11, dials oily part 10 and follows 1 shaft end 11 of connecting rod rotation pendulum
It is dynamic, it dials oily part 10 and stirs lubricating oil into lubricating oil liquid level lower section, lubricating oil splash is formed between 4 inner wall of piston cylinder and interior casing wall
Sputtering chamber, lubricating oil splashed to oily 10 activity of part is dialled in sputtering chamber.Oily part 10 is dialled to swing with the moving rotary of crank axle 3,
Lubricating oil is instigateeed, lubricating oil is random to be sputtered and hit to inboard wall of cylinder block, forms lubrication oil droplet, oil droplet is distributed to cylinder
The surface of each parts of body, is lubricated it.
As shown in Figure 1, Figure 2 and Figure 3, bearing, 1 shaft end 11 of connecting rod are equipped between 11 inside of shaft end of connecting rod 1 and crank axle 3
Place is equipped with the shaft end oilhole 100 for entering bearing for lubricating oil；Shaft end oilhole 100 connects sputtering chamber；Shaft end oilhole 100, which is located at, to be dialled
The front side of oily part 10.
In the present embodiment, oily 10 direction of rotation of part is dialled counterclockwise, to dial oily part 10 in Fig. 1 and is being moved to lowest part
When, group oily part 10, which is pushed forward, is shoved into lubricating oil into shaft end oilhole 100 so that lubricating oil is entered in bearing, to bearing
Position is lubricated.And dial the groove that oily 10 middle part of part is equipped with arc, the groove center of circle towards shaft end 11 stir lubricating oil liquid level when
Moving direction（Oily part 10 is dialled in bottom, oily part 10 is dialled and is in forward travel state）So that lubricating oil is used as by groove
It is oriented to so that a large amount of lubricating oil is entered in bearing, maximizes the inlet of its lubricating oil.
Crank axle 3 includes crank piece 31, and 1 side wall of connecting rod of shaft end 11 is bonded with crank piece 31,1 side wall of connecting rod of shaft end 11
Shaft end oil groove 110 is offered, shaft end oil groove 110 is in groove-like, and shaft end oil groove 110 connects sputtering chamber.Lubricating oil is led to
It crosses shaft end oil groove to enter between crank piece and connecting rod, reduces the abrasion between connecting rod 1 and crank piece 31.
As shown in figure 4,2 wall of piston is pivotally connected by pivot with filling in the connecting rod 1 at end 12, the connecting rod 1 at plug end 12 is equipped with plug end
Oilhole 120, plug end oilhole 120 connect pivot and sputtering chamber.Lubricating oil can be entered by filling in end oilhole 120 on pivot, drop
Abrasion between low pivot and plug end 12, and fill in the opening inclination of end oilhole 120 and set upward so that lubricating oil is easier to enter
The position.
As shown in Figure 4 and Figure 5, the side wall of piston 2 is equipped with piston oilhole 20, is stayed between 4 inner wall of 2 side wall of piston and piston cylinder
There are lubrication cavity 23, the connection of piston oilhole 20 lubrication cavity 23 and sputtering chamber；Lubricating oil splash passes through piston to 2 inside of piston
Oilhole 20 enters lubrication cavity 23, and oil ring 22 is equipped in lubrication cavity 23 and causes the distribution in lubrication cavity 23 of lubricating oil more
It is uniform.Lubricating fluid is lubricated 4 inner wall of piston cylinder so that being worn between 4 inner wall of piston 2 and piston cylinder reduces.
2 outer end side wall of piston is equipped with sealing ring 21, and sealing ring 21 enters combustion for preventing from lubricating lubricating oil in cavity 23
Burn indoor, lubricating oil avoided to participate in burning, when piston 2 is moved to the right, sealing ring 21 can by inner wall there are profit
Lubricating oil scrapes, it is made to be returned in sputtering chamber out of piston oilhole 20.
As shown in Figure 1,4 inner end of piston cylinder tilts down setting.The lubricating oil entered in piston cylinder 4 can be with gravity
Effect is flow back into inner casing again, and lubricating oil is avoided to be detained in piston cylinder 4 and enter in combustion chamber.
Since lubricating oil liquid level is excessively high, lubricating oil can leak out at the output shaft 30 of crank axle 3；Therefore it is lubricated in the present embodiment
The liquid level of oil cannot be excessively high, and in rotary moveable, there are spacing always with lubricating oil liquid level for the shaft end 11 of connecting rod 1, avoid connecting rod 1
Axle portion 11 contacts so that a large amount of lubricating oil leaks.
The above makes the preferred embodiment of the present invention, does not depart from this hair for those of ordinary skill in the art
Under the premise of bright principle, several variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
