Abstract
The invention discloses a wear-resisting pin shaft which comprises a pin shaft body.The outer surface of the upper portion of the pin shaft body is provided with an induction quenching layer, and the two ends of the lower portion of the pin shaft body are each provided with a gap.In this way, the wear resistance of the pin shaft is improved; meanwhile, after the pin shaft bears loads to be bent, the surface of the pin shaft body is not prone to cracks, fatigue fractures occurring in the using process are reduced, and the service life of the wear-resisting pin shaft is prolonged.
Description
Technical field
The present invention relates to the improvement of a kind of bearing pin, particularly a kind of wearability improving bearing pin；Simultaneously after bearing pin bending loaded, pin body surface is not likely to produce crackle, reduces the fatigue fracture occurred in use procedure；Increase the wear-resisting bearing pin in service life.
Background technology
Bearing pin is one of part on chain, and the bearing pin of conventional chain is usually integral quenching, temper.For the chain under special environment, in order to improve its anti-wear performance, surface induction hardening is also taked to process.But adopt conventional impewdance matching mode, owing to impewdance matching is much higher compared with bearing pin matrix, after bearing pin bending loaded, the easy crack initiation in surface, use procedure occurs fatigue fracture often.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of wearability improving bearing pin；Simultaneously after bearing pin bending loaded, pin body surface is not likely to produce crackle, reduces the fatigue fracture occurred in use procedure；Increase the wear-resisting bearing pin in service life.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is a kind of wear-resisting bearing pin, including: pin body；The outer surface on described pin body top is provided with impewdance matching layer；The two ends of described pin body bottom are equipped with a breach.
Preferably, the angle of described impewdance matching layer is 45 degree of-75 degree.
The invention has the beneficial effects as follows: the wear-resisting bearing pin of one of the present invention, impewdance matching layer is set by the outer surface on pin body top, improve the wearability of bearing pin；Simultaneously after bearing pin bending loaded, pin body surface is not likely to produce crackle；Reduce the fatigue fracture occurred in use procedure；Increase service life.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of wear-resisting bearing pin of the present invention.
Accompanying drawing 2 is the sectional view at Figure 1A-A place.
Wherein: 1, pin body；2, impewdance matching layer；3, breach.
Detailed description of the invention
Below in conjunction with accompanying drawing, presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
Referring to Fig. 1 and Fig. 2, the embodiment of the present invention includes:
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is a kind of wear-resisting bearing pin, including: pin body 1；The outer surface on described pin body 1 top is provided with impewdance matching layer 2；The two ends of described pin body 1 bottom are equipped with a breach 3, and described breach 3, in plane, confirms direction when being conducive to assembling；The angle of described impewdance matching layer 2 is 45 degree of-75 degree.
The invention has the beneficial effects as follows: the wear-resisting bearing pin of one of the present invention, impewdance matching layer is set by the outer surface on pin body top, improve the wearability of bearing pin；Simultaneously after bearing pin bending loaded, pin body surface is not likely to produce crackle；Reduce the fatigue fracture occurred in use procedure；Increase service life.
Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all falls within rights protection scope of the present invention.
