What types of pulleys are available for modern industrial use?
For modern industrial use, pulleys are generally defined by belt type. The pulleys are sprocket,synchronous, flat, round and V belts, which are used for the corresponding belt type. For example, synchronous belt pulleys contain teeth with notches that are spaced to engage the teeth of the matching belt. For flat belt pulleys, on the other hand, do not contain teeth because they are used for flat, smooth belts.V-belt pulleys contain an inclined belt track to fit the passing V-belt.
- Chain&Sprocket – Sprockets
- Flat Belt – Flat belt pulley
- Timing Belt – Timing belt pulley
- V-Belt- V Belt pulley
There are three structures of a pulley system in industry using:
- One has a fixed axle
- One has a moveable axle
- A compound, which is a mixture of the two
What are timing belt pulleys
Timing belt pulleys are a wheel on a shaft or an axle. It is developed in order to support the change of direction and movement of a belt or a cable along the circumference. Pulley is grooved in between two flanges all over its circumference. Toothed belts and pulleys are of major importance in synchronous drives based on flexible components.Their curilinear tooth profile was designed with high-speed and provide excellent registration without a loss in torque carrying capability making them ideal for precise registration applications and heavy loads. Timing belt drives are increasingly replacing inefficientroller chain sprockets for the transfer of power from shaft to shaft, torque multiplication, speed reduction, speed increase, and shaft synchronization.
Adavantages of timing belt pulley
Timing belts maintain system timing better through the use of a toothed profile and toothed pulleys or sprockets, and typically have a higher power density, allowing for smaller belt and pulley packages for a similar load. Because of these improvements, timing belts are also usually a more expensive option, are also usually a more expensive option.
- high level of synchronicity
- Low noisy
- No lubrication need
- A higher power density
- smaller belt and package for a similar load
Applications of Timing belt pulleys
Pulleys are widely used in marine, shipping and nautical applications; they also find use in various pieces of industrial equipment and machinery. For timing belt pulleys, they are used in industries where need an extremely high level of synchronicity. And the pulley must be able to perform under high rotational speeds of thousands of RPMs which can easily be seen during a typical driving profile. The toothed part of the belts stay effective in producing greater power transmissions and this property is found to be very suitable in driving automobile motors. Toothed belt supports for increasing the engine power and reduces the engine noise. Here, we list some typical timing belt pulley applications in industries.
Timing belt pulley applications
●Brick and Clay pug mills
●Mills, oven, and paper pulpers
●Agitators for liquid
