How to Select an Appropriate Transmission Belt?

Belts are mechanical components that are used to transmit power without causing phase shift. They are lightweight material loops used to link multiple spinning shafts, which are usually parallel mechanically. Belts may be used to transfer power or activity as a transmitting feature effectively.

How to select a transmission belt?

You'll have to know the kind of portion and the belt measurements to make the best decision. This guide will show you the various parts available on the market.

The application determines the type of belt to use:

  • torque to be distributed

  • rotational velocity

  • center distance

  • ratio of reduction

  • circumstances of temperature and lubrication

Why select a flat belt?

Like every other transmission belt device, the flat belt requires mechanical energy to be transferred from one pulley to another. Flat belts have a 98 percent performance rating, but they are only ideal for light loads. Flat belts can be self-centered by curved pulleys until the drive mechanism is balanced. Many power transmission systems use this kind of belt.


Broad flat belts can be used with large pulleys to provide high strength at incredible velocities.

  • About 98 percent more efficient than V-belts.

  • V-belts offer a shorter service life.

  • The process is very silent.

  • It is possible to have a significant center distance.

How is a round drive belt useful?

A round drive belt is a high-performance solution. It adds durability with minimal stretch for minimum take-up needs. It has a heavy-duty stress-relieved fabric cover for better durability.

Why select a V-belt?

These are the most frequently used power transfer belts. They transfer more power than flat belts at the same stress frequency. Variable-speed motors, for example, make use of them. They have the best traction, pace, bearing load, and life span configurations.


The belt's V-shaped segment follows a pulley pattern, stopping it from sliding and improving torque transfer.

  • It is thinner than a flat belt, so it uses less room.

  • It doesn't have to be as tense as it is now.

  • Between 300 and 2,130 m/min is the best speed level.

Why select a ribbed belt?

This type of belt is ribbed lengthwise, as the name implies, significantly increasing the contact area between the pulley and the belt. The ridge portion of the belt adheres to the pulley, and this is how it operates. Its one-piece design ensures a uniform spread of belt stress around the pulley's touch surface.


  • A broad power spectrum.

  • The product has a long lifespan and is dependable.

  • It is possible to achieve a high transmission ratio.

  • Consistent tension.

  • Transmission is silent.

Why select a synchronous slotted belt?

Synchronous belts are slotted. They're used to powering camshafts and the ancillary transmission on certain motorcycles, for example. They can also be used on a variety of commercial and agricultural equipment. Synchronous belts are necessary to prevent phase changes. And if it is very stiff, the slotted belt would still change due to its elasticity.


They ensure that the mechanism is coordinated and that action is communicated without slipping.

Unlike other belts, these belts can tolerate low speeds and need less initial friction because power transfer is achieved by gear meshing.

What is the purpose of a transmission belt?

The automobile industry is among the most well-known uses for belts: automobiles use a ribbed belt to synchronize the main engine components' motions (valve, pistons) during different operating cycles: the ribbed belt powers the alternator, power steering pump, water pump, and other peripheral parts.
