Flat Belt

Flat belts are a type of power transmission belts.

Belts used in industrial machinery to transfer and carry materials are called conveyor belts, or they transfer motor power or torque to other parts and bring rollers into rotation, which are called power transmission belts.

Unlike conveyor belts, flat belts do not have large dimensions and are not very wide.

Instead, they have very high power and tensile strength due to the special material they are made of. Flat belt is one type of power transmission belt.

Types of Flat Belts

One form of this belt is its leather type. This type can be two or multi-layered, and in its intermediate layers, textiles, weaves, and polymers may be used.

Leather flat belts are used in situations where there is a high risk of slippage and the process speed needs to be low.

Another type is the rubber flat belt. In this model, textiles, weaves, and threads are covered and coated with rubber. This product adheres well to pulleys and has high elasticity.

The third type is the woven flat belt. Depending on the thickness, it can have three to twelve layers. Weaves in this model can be made of linen fibers or synthetic fibers. They can be covered with rubber or left uncovered.

Flat belts, in addition to power transmission, like conveyor belts, can also transfer objects like flat belts. The movement of this type of belt is based on overcoming friction and has very high tensile strength.

Flat belts are drier than other types and are often cheaper, and one of their features is resistance to pollution and dust.

Flat belts are usually made up of several layers, and their thickness affects their resistance and overall strength. The common material for the surface and underside of the belt can be rubber, leather, or synthetic fibers.

Three factors that may reduce friction in flat belts and cause wear during movement are moisture, oil, and heat.

These multi-layer belts are commonly produced and supplied in three forms. The flat belt with a polyamide layer is more commonly used in cases where more power is needed.

The polyester-layered belt in its structure increases the speed in the machine's mechanism, and the third type of flat belt, which uses both polyamide and polyester layers in its structure, has both high power and speed.

The material of the surface and underside plays a role in wear and abrasion during movement. The thickness of the intermediate layer or polyamide and the type of fibers in this layer greatly affect the flexibility and tensile strength of the flat belt.

Increasing the thickness of this intermediate layer reduces flexibility and increases tensile strength and resistance.

German, Japanese, English, and Swiss brands are among the manufacturers of flat belts whose products are marketed in Iran and sold.

This product has average speed and strength. The fourth and last type is the flat belt with longitudinal threads. Longitudinal threads are made of linen or synthetic fibers.

This product is in the form of a loop and is very suitable for heavy-duty and high-speed processes. The elasticity of this type is low.

This product has a simple structure and requires larger pulleys for movement, and its main function is to transfer power and force in industrial machines.

The pulley used for the movement of the flat belt is commonly made of cast iron or steel and has two protrusions on its body to fix the belt in place.

Some general features of this type of belt include: Flat belts should be able to withstand a temperature range of 30 to 110 degrees Celsius.

These tools produce little noise during operation and do not have much sound pollution. Flat belts, due to their smooth and toothless groove, create low friction in the machine.

This product is resistant to chemical reactions.
