Abstract
The present invention relates to a kind of roller for roller chain, the roller bus of this roller chain is cydariform curve, the adverse effect of edge effect is reduced as a result of cydariform curve, improve the distribution of contact of Contact Pair, to ensure the uniformity of contact stress stress and further reducing edge effect, appropriate selection cydariform curve and cydariform amount, further to reduce contact stress peak value, make distribution of contact more reasonable so that roller stress tends to uniform, so as to improve the service life and bearing capacity of chain and sprocket driving device, improve the functional reliability and stability of chain and sprocket driving device.Due to roller chain roller and sprocket engagement when the contact stress peak value that produces reduce, be not susceptible to spot corrosion, abrasion, improve service life;The field of conjugate action there will not be larger sliding friction and abrasive wear simultaneously, and transmission efficiency also increases;And be conducive to the engaging-in of chain to nibble out, reduce rotational noise and improve the stationarity of work.
Description
Technical field
The present invention relates to a kind of roller for roller chain, it is mainly used in roller chain and set in chain and sprocket driving device
Cylinder chain, it is also possible to for bearing pin chain.
Background technology
Roller chain transmission device is used primarily in the strong machine driving of low speed, heavy duty, reliable operation, overload capacity
Power is big, dust is more, have the more severe occasions of environment such as pollution with transmitting.Because in above-mentioned workplace,
Roller chain transmission device has simple structure, handling ease for other transmission devices, overhauls conveniently
The advantages of.The engagement of roller chain and sprocket belongs to non-conjugated engagement, and the quality in its running is directly connected to
The reliability and service life of chain and sprocket driving device work.The roller outer surface of the roller chain of current structure is cylinder
Face, its bus is straight line, and when big torque is transmitted, roller two ends can produce obvious edge stress effect,
There is larger peak stress, cause roller discontinuity, exacerbate the abrasion of roller and sprocket wheel, so that
Influence the service life and bearing capacity and stationarity of chain and sprocket driving device.
The content of the invention
It is an object of the invention to provide it is a kind of wear and tear less, bearing capacity is higher, service life is more long for chain
The roller of roller chain in transmission device.
The technical scheme is that:A kind of roller for roller chain in chain and sprocket driving device, outside the roller
The curve of surface bus is to be close to the central raised cydariform curve of bus, and the roller bus is one or more snippets
Cydariform curve, therefore the adverse effect of edge effect is reduced, improve the distribution of contact of Contact Pair, reach
Two ends peak stress is reduced, the stress distribution of roller can be effectively improved and the use of whole chain and sprocket driving device is improved
Life-span.To ensure the uniformity of distribution of contact and further reducing edge effect, the cydariform curve tool
There is certain cydariform amount.Using appropriate cydariform curve and the design of cydariform amount so that roller stress tends to
Uniformly, reducing the EDGE CONTACT stress of roller so that distribution of contact is more reasonable, and then improves chain
The service life and bearing capacity of transmission device, improve the functional reliability and stability of chain and sprocket driving device.
Further technical scheme is the present invention:The cydariform curve of the roller bus can be optionally one of following,
The Wave curved of logarithmic curve, circular curve, sine curve, elliptic curve and multi-section circular arc curve composition.
Further technical scheme of the invention is:The roller bus cydariform curve is using logarithmic curve as drum
Shape curve, the improvement to edge stress effect is the most obvious, and the cydariform curve of the roller bus is preferably right
Number curve.
Further technical scheme is the present invention again:The cydariform amount of the logarithmic curve of the roller bus, both
Ensure cydariform effect, avoid excessive cydariform amount to reduce contact area on the contrary again, make localized contact stress
Raise, hollow roller is taken into account again the flexibility of certain elastic deformation and rotation, and the cydariform amount takes
Value scope is between 0.005~0.02mm.
The beneficial effects of the invention are as follows:Using this roller bus central raised cydariform curve and appropriate drum
The technical scheme of shape amount, to reduce the EDGE CONTACT peak stress of roller, and causes that roller stress tends to uniform.
The contact stress peak value produced when the roller of roller chain is with sprocket engagement is smaller, is not susceptible to spot corrosion, abrasion,
Improve service life and bearing capacity;The field of conjugate action there will not be larger sliding friction, transmission efficiency simultaneously
Also increase;Further, since using this technical scheme, being conducive to the engaging-in of chain to nibble out, slow down
Vibration, reduces rotational noise and improves the stationarity of work.Roller outer surface bus can using cydariform curve
Avoid material from assembling, accelerate the very fast leaving side of material, can further reduce dust and other impurities to sprocket wheel and chain
The abrasive wear of bar.In a word, it is this optimization roller chain roller be adapted to bearing capacity it is higher, service life compared with
Long, transmission is relatively steady, and abrasion is normal and reduces maintenance.
Brief description of the drawings
Fig. 1 is the mesh schematic representation of roller chain transmission device
Fig. 2 is prior art roller generalized section
Fig. 3 is present pre-ferred embodiments roller section (curve is exaggerated) schematic diagram
Specific embodiment
Roller chain transmission device as shown in Figure 1, is made up of, the tooth of sprocket wheel 1 sprocket wheel 1 and roller chain 2
Wide 3 engage with the outer round surface of the roller 4 of roller chain 2.
As shown in figure 3, the basis of the roller face of cylinder straight edge line 5 in the roller chain of prior art shown in Fig. 2
On, the roller straight edge line 5 of roller chain is optimized for be close to the central raised cydariform curve of bus, the roller
Bus 5 is one or more snippets cydariform curve, therefore reduces the adverse effect of edge effect, improves Contact Pair
Distribution of contact, reaches reduction two ends peak stress, can be effectively improved the stress distribution of roller.To ensure
The uniformity of distribution of contact and further reduction edge effect and service life, the cydariform curve should be selected
Select appropriate cydariform amount δ 6.
Further technical scheme is:The cydariform curve of the roller bus 5 can be optionally one of following, logarithm
The wave smooth curve of curve, circular curve, sine curve, elliptic curve and multi-section circular arc curve composition.
Further technical scheme is:The cydariform curve of the roller bus 5 is preferably logarithmic curve.
Further technical scheme is again:The cydariform amount δ's 6 of the logarithmic curve of the roller bus 5 takes
Value scope is between 0.005~0.02mm.
Above-described embodiment is used for illustrative purposes only, and not limitation of the present invention, as long as chain with
During sprocket engagement, the roller bus of chain is cydariform curve, no matter and hoisting-chain, haulage chain and driving-chain,
And the chain of the different purposes such as single, double row roller chain, can fall within the scope of the present application.
