Welded-Steel-Type Drag Chain
·According to ASME B29.18M Steel Welding Traction Chain,Accessories and SprocketTooth Profile and ISO 6971 Welding Structure Curved Plate Traction Chain,Accessoriesand Sprocket,there are many kinds of accessories to choose from,and they can also becustomized and developed according to users requirements.
·The structure of the curved plate chain with the drawing welding structure is basicallythe same as that of the curved plate chain with the engineering welding structure.Thesleeve welded with the curved plate is a non-circular special-shaped pipe,the outercircular surface of the sleeve is engaged with the sprocket,and the non-circular surfaceis consistent with the running direction of the chain,which is used for pushing orscraping materials.
·High-quality steel and advanced technology are selected for production.Special-shaped sleeve parts are seamless steel pipes formed by precision drawing,ensuringaccurate sleeve size and good meshing with sprocket,and adopting advanced andefficient welding special equipment for reliable welding quality:There are two kinds ofproducts with different tensile strength indexes to choose from.
·Curved plate chain with traction welding structure is a chain used in traction conveyor,which is suitable for conveying large or stacked bulk materials.

WEAR

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the two sprockets, since it is always the smaller one that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the two sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
