Abstract
The present invention relates to a kind of high-power engine driving-chain bearing pin and the method for assembling chain, bearing pin two ends diameter is less than middle part diameter, and bearing pin two ends end face is provided with swell centre bore.During chain assembling, making bearing pin head end swell deform in taper die press-in swell centre bore, the head end of swell realizes being accurately positioned of carrier bar with the bearing pin shaft shoulder, is prevented effectively from bearing pin and play occurs in chain plate hole.This connected mode exerts oneself big 50% 150% than traditional corner riveting, and bearing pin weight reduces 5% 10%, and bearing pin is along the circumferential direction evenly distributed with the chain plate hole magnitude of interference.
Description
Technical field
The present invention relates to a kind of engine fittings, particularly to a kind of high-power engine driving-chain bearing pin and assembling chain
Method.
Background technology
Chain in use carrier bar is often and the gear teeth produce side grinding and collision, makes carrier bar drag riveting under responsive to axial force
The danger fallen apart.Therefore, chain riveted must be firmly.
The common two jiaos of rivetings of die mode of engine chain industry, corner riveting.Traditional die mode axially positions loosely
Gu, on high-power engine, shock loading is big, and bearing pin easily occurs fretting wear, after working long hours, bearing pin meeting in chain plate hole
Occur substantially to rotate relative to carrier bar.Under this state, bearing pin is produced and shears and abrasion by carrier bar, reduces bonding strength, thus
Affect chain service life.Two jiaos of rivetings or corner riveting are bearing pin head end region swell so that chain plate hole contacts with bearing pin
, there are stress raisers, affect the fatigue behaviour of carrier bar in power along the circumferential direction skewness.
Summary of the invention
For overcoming prior art not enough, the present invention proposes a kind of high-power engine driving-chain bearing pin connected mode, improves
Bearing pin fastening strength, reduces stress and concentrates, and reduces weight chain while improving chain service life.
By theory analysis and verification experimental verification, bearing pin and chain plate hole are interference fit, adjust by the way controlling the magnitude of interference
Fastening strength.Driving engine chain bearing pin conventional coupling arrangement is two jiaos of rivetings or corner riveting, along chain plate hole circumferencial direction interference
Amount difference, easily occurs stress to concentrate, affects the fatigue life of carrier bar.On conventional coupling arrangement, carrier bar is the most reliable on bearing pin
Axial location, when, under big load applying working condition, when axial force suffered by bearing pin is more than fastening force, bearing pin can be altered vertically
Dynamic, easily cause and drag riveting, cause chain to fall apart.
For this situation, the present invention proposes a kind of high-power engine driving-chain bearing pin connected mode.Its bearing pin two
End diameter less than middle part diameter, 80% the 90% of a diameter of middle part, two ends diameter, head end path Partial Height be with
Cooperation thickness of link plates 155% 185%.Bearing pin head end is provided with swell centre bore, and end part of pin shaft aperture is head end external diameter
20% 40%, end part of pin shaft hole depth is 85% the 110% of matched thickness of link plates.
Assembly method is: bearing pin inserts in chain plate hole, and the bearing pin shaft shoulder is fitted with carrier bar.Taper die pressure pin shaft end
In hole, hole swell being turned up, valgus dividing potential drop is put down.
This bearing pin connected mode passes through the deformation of bearing pin head end, the bearing pin shaft shoulder and the bearing pin magnitude of interference with hole firmly bearing pin
It is fixed together with carrier bar, effectively prevents bearing pin from play occurring in chain plate hole.This connected mode bearing pin and the interference of chain plate hole
Amount is along the circumferential direction evenly distributed, and is prevented effectively from stress and concentrates.This connected mode is riveted tightly tenacity big 50% than traditional corner
150%.The change of pin shaft structure simultaneously makes its weight reduce 5% 10%.
Accompanying drawing explanation
Fig. 1 is pin shaft structure figure；
Fig. 2 is bearing pin front view.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is further detailed explanation:
In a kind of high-power engine driving-chain bearing pin connected mode, bearing pin includes bearing pin main body 1, bearing pin head end 2, pin shaft hole 3.
Its technical characteristics is the 85% of bearing pin head end 1 a diameter of bearing pin main body 1 diameter, and bearing pin head end 2 path Partial Height is therewith
Coordinating the 160% of thickness of link plates, the aperture of pin shaft hole 3 is the 30% of head end external diameter, and bearing pin head 3 hole depth is matched chain thickness of slab
The 100% of degree.
This bearing pin connected mode passes through the deformation of bearing pin head end, the bearing pin shaft shoulder and the bearing pin magnitude of interference with hole firmly bearing pin
It is fixed together with carrier bar, effectively prevents bearing pin from play occurring in chain plate hole.This connected mode bearing pin and the interference of chain plate hole
Amount is along the circumferential direction evenly distributed, and is prevented effectively from stress and concentrates.This connected mode is riveted tightly tenacity big 123% than traditional corner.With
Time pin shaft structure change make its weight reduce 6%.
Embodiment 2
A kind of high-power engine driving-chain bearing pin, bearing pin two ends diameter is less than middle part diameter, and bearing pin two ends end face is provided with
Swell centre bore.The 83% of a diameter of middle part, two ends diameter.Swell centre bore path Partial Height is matched chain thickness of slab
The 172% of degree.Swell centre bore path is the 25% of two ends external diameter.Swell depth of center hole is the 98% of matched thickness of link plates.
This connected mode is riveted tightly tenacity big 132% than traditional corner.The change of pin shaft structure simultaneously makes its weight reduce 8%.
Embodiment 3
A kind of high-power engine driving-chain bearing pin, bearing pin two ends diameter is less than middle part diameter, and bearing pin two ends end face is provided with
Swell centre bore.The 87% of a diameter of middle part, two ends diameter.Swell centre bore path Partial Height is matched chain thickness of slab
The 175% of degree.Swell centre bore path is the 35% of two ends external diameter.Swell depth of center hole is matched thickness of link plates
100%.This connected mode is riveted tightly tenacity big 142% than traditional corner.The change of pin shaft structure simultaneously makes its weight reduce
5.5%。
