Buy Best-in-Class Flat Belt Pulleys from Emechmart
Flat belt pulleys are used in transmission systems driven by flat belts, typically in high-speed, low-power applications in textile, papermaking and office machinery such as computer printers. Flat belt pulley is also used for conveyors. Compared to pleated belts of similar horsepower, flat belts are 25% or thinner, making flat belt pulleys smaller than V-belt pulleys.
As the top flat belt pulley suppliers, you will find flat belts are also more affordable at our online store. One safety factor is that the belt may slip in the event of over-torque, preventing damage to equipment other than the belt. Flat belt drive pulleys apply a driving force to the belt. They do not need an oval flat belt pulley. A flat pulley idler can also be used for the reverse side of a traditional V-belt.
Special features of Flat belt pulley at Emechmart
The flat belt and pulley may have a moulded crown, which helps centre the belt, prevents rubbing against the outer flanges, and provides support at the centre of the belt where tension is highest. The crowning of flat belt pulleys also helps keep the flat belt on the belt pulley, and the belt tends to be the tightest. A flat belt drive sometimes includes a tracking sleeve or other mechanism to keep the belt on the flat pulley.
A flat belt is a simple power transmission system that was perfect for its day. It can deliver higher power at higher speeds (500 hp at 10,000 ft/min or 373 kW at 51 m/s) in the case of wider belts and larger pulleys.
But these wide-belt-large-pulley drives are heavy, take up a lot of space, require high tension leading to high loads, and are poorly suited for close hubs, so V-belts mainly Used for short distances.
Long-distance power transmissions are usually not belted at all and it is considered as an advantages of flat belt pulley. For example, factory machines now have separate electric motors. Thus, the machines have certain specifications that flat belt pulleys must include:
· Belt width
· Outside the circle
· Bore size
· Hub diameter
· Hub projection
Tension on flat belts is usually determined by adjusting the distance between the pulleys by a small amount, such as 2%, to stretch the belt.
Types of Pulleys for Flat Belts
The different types of pulley for flat belt are as follows:
Cast Iron Pulley: Due to its low cost the winch is usually made of cast iron. The rim is held in place by a net of central masters or by arms or spokes.
Steel Pulley: Steel pulley is made from pressed steel sheet and has great strength and durability. These pulleys are lighter in weight about 40 to 60% less than cast iron pulleys of similar capacity and are designed to run at high speeds.
Wooden Pulleys: Wooden pulleys are lighter and have a higher coefficient of friction than cast iron or steel. These pulleys have 2/3 the weight of cast iron pulleys of the same size. They are typically made from selected maple that has been cast into sections and glued together under great pressure.
Paper Pulley: Paper Pulley is made from compressed paper fibers with metal in between. These pulleys are commonly utilised for belt transmission from electric motors when the center-to-center shaft distance is small.
Fast and loose pulley: A fast and loose pulley used on the shaft can turn the machine on or off at will. A fast pulley is attached to the machine shaft while a loose pulley moves freely.
