A sprocket or sprocket-whee is a profiled wheelwith pearly whites, or cogs that mesh with a chain, track or additional perforated or indented materials The name ‘sprocket’ applies generally to any wheel upon which radial projections engage a chain moving over it. It is distinguished from a equipment in that sprockets should never be meshed together straight, and differs from a pulleyin that sprockets have the teeth and pulleys are clean.
Sprockets are used in bicycles ,motorcycles, vehicles, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or even to impart linear movement to a monitor, tape etc. Most likely the most common form of sprocket may be found in the bicycle, where the pedal shaft bears a large sprocket-steering wheel, which drives a chain, which, subsequently, drives a little sprocket on the axle of the trunk wheel. Early on automobiles were also largely powered by sprocket and chain device, a practice mainly copied from bicycles.
Sprockets are of various designs, no more than efficiency becoming claimed for each by their originator. Sprockets typically do not have a flange ,Some sprockets used in combination with timing belts ,have flanges to keep the timing belt centered. Sprockets and chains are as well used for power tranny from one shaft to some other where slippage isn’t admissible, sprocket chains simply being used rather than belts or ropes and sprocket-wheels instead of pulleys. They might be run at large speed and some forms of chain happen to be so constructed as to be noiseless also at high speed.
When a sprocket has worn, it can trigger rapid chain wear and will should be replaced at the initial available opportunity.
Replace it too early, however, and you could be incurring unnecessary costs.
Examining a sprocket
In the event that you examine the faces of the sprocket teeth you should be able to tell immediately whether a sprocket has worn or not.
What you are searching for is a shiny strip on each of the teeth, about the pitch circle size, as indicated in the illustration below:
It is well worth noting though a high-quality sprocket will probably have seen several chains before it displays anything like the degree of wear displayed above.
Misaligned sprockets are a common reason behind premature chain wear, and so when sprockets are substituted it is important they are properly aligned with the shafts.
After the shafts and sprocket tooth faces are accurately aligned, the load will be distributed evenly across the whole chain width which will help to achieve optimum service life.
To check on for wobble, a direct edge, nylon line or laser sight tool ought to be used over the machined faces of the sprockets in several positions. You can then drive the keys residence as a final check.
Hardened teeth
Sprocket tooth wear may also occur when low grades of sprocket materials have been used, or when using little sprockets with a speed ratio greater than 4:1.
It is suggested to manufacture the sprockets with hardened teeth to overcome a number of the issues associated with escalating tooth wear.
FB Chain gets the engineering capability to offer sprockets in products to suit the application circumstances, such as special grade alloy steels.
Split sprockets
Another FB Chain speciality is our ability to manufacture high-quality sprocket segments. Split sprocket solutions can save huge amounts of downtime in terms of replacing large, difficult-to-access drives.
A sprocket is a wheel with tooth upon which a flexible machine for instance a chain or belt rides. The rotation of the sprocket advances the chain or belt. Picture a bicycle chain assembly or a bulldozer track and you possess the concept.
Ever-power manufactures miniature 0.1475″ pitch sprockets with a pitch size less than 1/2 ” (0.431) ranging up to 4 inches (3.992) available in stainless steel, anodized aluminum, nylon, or phenolic material. These are designed to be paired with miniature stainless chain weighing only 0.03 pounds per foot, given connectors or customized with riveted limitless loops.
Ever-power offers the even more muscular 0.1875″ pitch and #25 chain in carbon steel or stainless steel that can handle work loads up to 70.4 pounds with an average tensile durability of 506 pounds. Nickel plated #25 chain is also readily available. Hub or hubless type sprockets for these chains can be found in share or by special order, according to the pitch, number of teeth, and specialized drilling or reboring. They can be found in carbon steel, glass reinforced Nylon, and light weight aluminum.
Flexible timing chain is manufactured with a polyurethane-covered Kevlar® or STAINLESS core in 0.1475″ pitch (.230″ chain width) or 0.15708″ pitch (.220″ chain width) with a tensile power of 100 pounds. Coordinating pin hub or hubless sprockets can be found in 303 STAINLESS or anodized aluminium with inventory bore diameters of 1/8 to 3/8 inches. Sprocket features that can be customized incorporate lightening holes, pitch lengths, slotted hubs, and number of teeth. Contact a Ever-electric power representative for unlisted configurations.
