Abstract
The invention relates to a hinge pin, in particular to a hinge pin with inclined oil holes, and belongs to the technical field of connecting pieces. The hinge pin comprises a hinge pin body, wherein a plurality of first axial oil transportation holes and a plurality of second axial oil transportation holes are formed in one end of the hinge pin body, and first drainage grooves which are the same with the first axial oil transportation holes in number are formed in the peripheral surface of the hinge pin body. Second drainage grooves which are the same with the second axial oil transportation holes in number are formed in the peripheral surface of the hinge pin body, and each second drainage groove is directly communicated with the corresponding second axial oil transportation hole. The four corners of each first drainage groove are communicated with the corresponding first axial oil transportation hole in the peripheral surface of the hinge pin body. According to the hinge pin, the oil holes can be more conveniently dredged under the condition that an oil duct is blocked, losses of a part making contact with a shaft are reduced, the service life is prolonged, and maintenance cost is reduced.
Description
Technical field
The present invention relates to a kind of bearing pin, a kind of bearing pin with inclined oil hole of air, belongs to link technical field specifically.
Background technique
Bearing pin, for connecting two or more component in relative rotation that have, in the process of rotating relative to bearing pin at component, can produce larger frictional force, therefore need to use oil lubrication.For convenient, on the periphery of bearing pin, add lubricant oil, conventionally on an end face of bearing pin, be provided with axial oil transportation channel, and on the periphery of bearing pin, be provided with radially oil transportation channel, axially oil transportation channel communicates with oil transportation channel radially, lubricant oil by axial oil transportation channel and radially oil transportation channel enter on bearing pin periphery, and then be diffused into the periphery of whole bearing pin, because the working environment of bearing pin is poor, the dust that the external world enters easily hinders the diffusion of lubricant oil, the face of parts of causing contacting with axle can not lubricate preferably, make the too early wearing and tearing of component and bearing pin.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby a kind of inclined oil hole of air formula bearing pin is provided, can to oilhole, dredge more easily, reduce the loss of the parts that contact with axle, reduce maintenance cost.
According to technological scheme provided by the invention, inclined oil hole of air formula bearing pin comprises bearing pin body, it is characterized in that: bearing pin body one end is provided with a plurality of first axial oil transportation hole and a plurality of second axial oil transportation hole, bearing pin body external peripheral surface is provided with first drainage trough identical with the first axial oil transportation hole number, and each first drainage trough is directly communicated with one first axial oil transportation hole; Bearing pin body external peripheral surface is provided with second drainage trough identical with the second axial oil transportation hole number, and each second drainage trough is directly communicated with one second axial oil transportation hole; Four angles of each the first drainage trough are communicated with respectively a first oil transportation hole radially that is arranged on bearing pin body external peripheral surface, and four angles of each the second drainage trough are communicated with respectively a second oil transportation hole radially that is arranged on bearing pin body external peripheral surface.
Further, a plurality of first axial oil transportation hole distributes along bearing pin body even circumferential.
Further, a plurality of second axial oil transportation hole distributes along bearing pin body even circumferential.
Further, the through hole of a plurality of first axial oil transportation hole for tilting.
Further, the through hole of a plurality of second axial oil transportation hole for tilting.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, the in the situation that of stopping up of oil channel, can to oilhole, dredge more easily, reduces the loss of the parts that contact with axle, increases the service life, and reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention.
Fig. 2 is plan view of the present invention.
Description of reference numerals: 1-bearing pin body, 2-the first axial oil transportation hole, 3-the first drainage trough, 4-first be oil transportation hole, 5-the second axial oil transportation hole, 6-the second drainage trough, 7-second oil transportation hole radially radially.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises bearing pin body 1, bearing pin body 1 one end is provided with a plurality of first axial oil transportation hole 2 and a plurality of second axial oil transportation hole 5, the a plurality of first axial oil transportation hole 2 distributes along bearing pin body 1 even circumferential, and a plurality of second axial oil transportation hole 5 distributes along bearing pin body 1 even circumferential.The described a plurality of first axial oil transportation hole 2 and a plurality of second through hole of axial oil transportation hole 5 for tilting.
Bearing pin body 1 external peripheral surface is provided with first drainage trough 3 identical with the first axial oil transportation hole 2 quantity, and each first drainage trough 3 is directly communicated with one first axial oil transportation hole 2.Bearing pin body 1 external peripheral surface is provided with second drainage trough 6 identical with the second axial oil transportation hole 5 quantity, and each second drainage trough 6 is directly communicated with one second axial oil transportation hole 5
Four angles of each the first drainage trough 3 are communicated with respectively a first oil transportation hole 4 radially that is arranged on bearing pin body 1 external peripheral surface, lubricant oil enters the first drainage trough 3 by the first axial oil transportation hole 2, pass through again radially oil transportation hole 4 of the first drainage trough 3 introducings first, bearing pin body 1 and part surface of contact are lubricated.Four angles of each the second drainage trough 6 are communicated with respectively a second oil transportation hole 7 radially that is arranged on bearing pin body 1 external peripheral surface, and lubricant oil enters the second drainage trough 6 by the second axial oil transportation hole 5, then introduce the second oil transportation hole 7 radially by the second drainage trough 6.
The present invention is simple in structure, compact, reasonable, the in the situation that of stopping up of oil channel, can to oilhole, dredge more easily, reduces the loss of the parts that contact with axle, increases the service life, and reduces maintenance cost.
