The Method Of Selecting A Transmission Belt

For making your choice of choosing transmission belts proper, you need to be aware of the kind of section beside the dimensions of the belt.

The kind of belt you must use is dependent on the kind of application you have like:

  • Reduction ratio
  • Lubrication and temperature conditions
  • The torque that needs to be transmitted
  • Center distance
  • Rotational speed

Benefits of belt drives

In comparison to various other systems of transmission, like chains or gears, belts propose numerous benefits like:

  • Belt drives are more flexible.
  • Belt drives are quieter.
  • You do not need to lubricate a belt drive.
  • Belt drives don’t need a parallel shaft.
  • You can activate the clutch action by discharging the tension of the belt.
  • Belt drives propose protection against obstruction and overload.
  • The belt drives are efficient from 95 percent to 98 percent.
  • You can easily install and maintain a belt drive.
  • Belt drives increase the life of a machine service because of the absorption of load fluctuations.
  • Belt drives have a low cost of the total installation.
  • A belt drive also requires low maintenance costs.
  • When there is a large gap between the shafts, belt drives become a highly economical option.

Types of belts

Every power transmission belt is either a positive drive or friction drive. The positive drive belts depend on the teeth’ engagement on the belt, and there isn’t any slip of positive drive belts except for tooth jumping or ratcheting.

On the other hand, friction drive belts depend on the friction between the pulley and the belt for transmitting power. They need tension for maintaining the ideal amount of friction. A flat belt is considered the purest type of friction drive, whereas V-belts possess friction multiplying influence due to the wedging action.

What are flat belts?

A modern flat belt is created from rubberized and reinforced fabric, which proposes high friction levels and strength with the pulley. This lessens the requirement for higher tension. Various surface patterns of flat belts do serve different transmission needs. A longitudinal groove lessens the air cushion that a flat belt generates in a high horsepower application and outdoor installation. The job of the air cushion is lessening the friction between the belt and the pulley. The groove almost lessens the effects of grease, oil, dust, and dirt and helps in lessening the levels of noise.

Get known to synchronous belts

The asynchronous belt has a toothed profile, which mates with a corresponding groove present in the pulley. The synchronous belts propose a similar optimistic engagement as chains or gears. People use synchronous belts in various applications where positioning, indexing, or a proper ratio of speed is needed. A synchronous belt is capable of wearing rapidly when pulleys tend to be misaligned, particularly in a long-center-distance drive. A recent advancement has created a pulley and a belt which utilize a V-shaped tooth instead of a straight tooth shape. This runs quieter compared to other shapes and does not need pulley flanges.
