Abstract
The utility model discloses a piston pin on diesel engine, including the shank, the pinhole has been seted up in the shank, the annular groove has been seted up to the outer peripheral face of shank, be provided with the fine cotton piece of annular glass in the annular groove, the oil filler point has been seted up to the tip of shank, lubrication groove intercommunication on oil filler point and the shank inner wall. The advantage is: the utility model has the advantages of simple structure, effectively noise absorbing and oil addition are comparatively convenient for they.
Description
Technical field
This utility model belongs to diesel engine part technical field, especially relates to the piston pin on a kind of diesel engine.
Background technology
At present, the piston pin on diesel engine with piston with the use of time can produce certain noise, this easily increases the weight of the noise pollution of periphery working environment；Also having is exactly that existing piston pin also exists bigger inconvenience when needing oil addition；It is therefore desirable to improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that the piston pin on a kind of diesel engine, and it has simple in construction, can effectively absorb noise and oil addition conveniently feature.
To achieve these goals, this utility model be the technical scheme is that the piston pin on a kind of diesel engine, including shank, offers pin-and-hole in described shank；The outer peripheral face of described shank offers annular groove, is provided with annular glass cotton block in described annular groove；The end opens of described shank has oil filler point, and described oil filler point connects with the oil-way on shank inwall.
The two ends of described oil-way have certain level interval.
Described annular groove is three, and it is equidistantly distributed on shank.
The inwall of described pin-and-hole is coated with wearable ceramic coat layer.
Adopt after said structure, this utility model compared to the prior art advantageously: simple in construction of the present utility model, the annular glass cotton block in shank outer peripheral face annular groove can absorb its operationally produced noise, effectively reduces noise pollution；And the wearable ceramic coat layer of pin-and-hole inwall can strengthen its with piston with the use of time abrasion resistance, increase the service life；Shank offers oil filler point, and oil filler point connects with the oil-way on pin-and-hole inwall, the convenient inwall oil addition to pin-and-hole of this structure, it is prevented that component wear.
Accompanying drawing explanation
Fig. 1 is planar structure schematic diagram of the present utility model.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, below in conjunction with drawings and Examples, this utility model is further illustrated.
Embodiment, as shown in Figure 1: the piston pin on a kind of diesel engine, including shank 10, offers pin-and-hole 11 in shank 10, the outer surface of shank 10 and the inwall of pin-and-hole 11 are respectively provided with carburized layer, and carburized layer can improve the overall stiffness of shank 10.Outer peripheral face at shank 10 offers annular groove 12, and annular groove 12 is three, and it is equidistantly distributed at the front portion of shank 10, middle part and rear portion respectively；Being provided with annular glass cotton block 13 in annular groove 12, annular glass cotton block 13 can absorb shank 10 operationally produced noise, effectively reduces noise pollution.Offering oil-way 15 on the inwall of pin-and-hole 11, the two ends of oil-way 15 have certain level interval, this structure arrange can lubricate more abundant；End opens at shank 10 has oil filler point 14, and oil filler point 14 connects with oil-way 15；So by injecting lubricating oil on oil filler point 14, then lubricating oil is allowed to be flowed in oil-way 15, in order to the inwall of pin-and-hole 11 is lubricated.Being coated with wearable ceramic coat layer on the inwall of pin-and-hole 11, wearable ceramic coat layer can strengthen the abrasion resistance of pin-and-hole 11 inwall, extends its service life.
