Belt and pulley functions

The functions of timing belt pulley in their various applications are given below:

·   The primary function of a belt is to transfer power (rotary energy) from one source to another. At the same time, the pulley, which has a groove around its circumference, allows the belt to pass easily through it while transmitting the rotational motion.

·   The design of a flat belt pulley to achieve various diameter functions is used to increase or decrease the speed of application of its forces.

·   These pulleys are often found on heavy-duty applications and are not used to transmit rotational motion.

·   Finally, the function of the belt is to apply force from one direction, either vertically or horizontally, depending on the position of the energy source and the application conditions that this force will.

·   A pulley is not used to transmit rotational motion as it is used to lift heavy loads. A pulley helps reduce the amount of force required to lift a load.

Applications for belts and pulleys

Belts and pulleys are also used in air compressor engines, agricultural equipment, conveyor belt pulley, etc. Belts and pulleys are intentionally designed for any application requiring another source's rotational motion. Many machines and tools range from big to small, like winches, treadmills, washing machines, etc.

A motor belt pulley that changes the direction of force is used on cranes, to pull out buckets, raise flags, adjust window blinds, etc. Below are examples of belt and pulley applications:

·   In bulldozer, it is used for lifting

·   An extended ladder

·   Using a crane in a construction site

·   Up or down the escalator

·   Opening and closing the garage door

·   Belts and pulleys in vehicles

·   The height uses multiple pulleys to do its job

·   Various fitness or exercise equipment use pulleys

·   Curtains in theatre halls use a pulley, which makes them easy to separate

Type of belts and pulleys at Emechmart

Below are the different types of types of pulley belts that are considered as the most popular products at our online store:

Open Belt Drive

In this type of pulley, the shaft rotates in one direction. The shafts are arranged in parallel directions. This means the direction of rotation is the same as that of the driven pulley.

Crossed Belt Drive

A crossed lung has greater transmissive power but cannot move as fast. This can cause belt wear. The shaft rotates against the pulley. To reduce wear in these pulley types, a greater distance between the pulleys should be maintained and then run at a lower speed.

Fast and loose cone pulley

In this type of pulley, there are two pulleys, the first is faster than the second. The fast pulley is mounted on the shaft with a keyed joint while the loose pulley rotates freely on the shaft. This loose pulley does not transmit any power. This type of pulley is suitable for multiple machines that receive power from a single source.

Stepped cone pulley

Stepped cone pulley is also known as speed cone. In these pulley types, more than one pulley of different diameters is adjacent to each other. Stepped cone pulleys are used in applications that require gear shifting or where the speed of the moving shaft changes frequently, such as in machines. The same belt is used to achieve different speeds.
