Ontology 1, axis rank 2, oil storage tank 3, Circumferential oil groove 4, axial oil groove 5, pouring orifice 6, fuel feed hole 7, oil-through-hole 8 and threaded mounting hole 9,
Wherein：The pin body 1 includes axis rank 2 and oil groove, and the oil groove includes several Circumferential oil grooves 4 being located in pin body 1
With several axial oil grooves 5, the Circumferential oil groove 4 and axial oil groove 5 communicate, and the end face center of the axis rank 2, which runs through, a radial direction
Straight slot, is additionally provided with a radial indentation 21 on 2 end face of axis rank, and 1 outer circle of the pin body is nearby equipped with an axial fuel inlet hole
7, there are three radial oil-through-holes 8, the oil-through-hole 8 to be communicated with the oil groove for connection on the fuel feed hole 7, the fuel feed hole 7
Pouring orifice 6 is located on the bottom surface of the radial indentation 21, and the internal thread for blocking lubricating oil, institute are equipped at the pouring orifice 6
It states 1 middle part of pin body and is circumferentially with an oil storage tank 3, the threaded mounting hole 9 is located at the both ends of the surface center of pin body 1.
Further, an oil-through-hole 8 positioned at 1 middle part of pin body is set to the inside of oil storage tank 3.
Further, the pin body 1 uses modifier treatment.
Advantageous effect caused by the utility model is：The utility model designs a kind of high-efficiency lubricating axis pin, by pin
Oil groove is arranged in shaft body with in-line to be connected, the abrasion between axis pin and contact component is effectively reduced, to play
The purpose for improving working effect and prolonging the service life.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the right view of the utility model embodiment.
In figure：1- pin bodies, 2- axis rank, 21- radial indentations, 3- oil storage tanks, 4- Circumferential oil grooves, 5- axial oil grooves, 6-

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, so that the advantages of the utility model and feature is easier to be readily appreciated by one skilled in the art.Based on this reality
With the embodiment in novel, any technical person familiar with the field do not obtained by creative work it is all other
Embodiment shall fall within the protection scope of the present invention.
As Figure 1-Figure 2, the present embodiment provides a kind of high-efficiency lubricating axis pins, including pin body 1, axis rank 2, oil storage tank
3, Circumferential oil groove 4, axial oil groove 5, pouring orifice 6, fuel feed hole 7, oil-through-hole 8 and threaded mounting hole 9, pin body 1 include axis rank 2
And oil groove, the oil groove include Circumferential oil groove 4 and axial oil groove 5, it is uniformly distributed on the outer circumference surface of pin body 1 there are six（At least six
It is a）Axial oil groove 5 is circumferentially with one to reduce the number of filling lubricating oil in the middle part of the outer circumference surface of pin body 1
Oil storage tank 3 is arranged with four in the pin body 1 of 3 both sides of oil storage tank（At least four）Circumferential oil groove 4, the week
It is communicated to oil groove 4 and axial oil groove 5；It is radial scarce to be additionally provided with one through there is a radially through groove for the end face center of axis rank 2 on the end face
Mouth 21（Referring to Fig. 2）, it is preferable that radial indentation 21 and radially through groove are set as plumbness；The outer circle of pin body 1 is nearby equipped with
One axial fuel inlet hole 7, there are three radial oil-through-holes 8 for connection on fuel feed hole 7, and three oil-through-holes 8 are communicated with oil groove respectively, wherein
