 The High Performance V-Belt looks like a relatively benign and simple device. They are basically glorious rubber bands, right? Need to be replaced? Just measure the width and circumference of the top, find another belt of the same size, and pat it on the drive. The only problem is: this method is almost wrong.

  Since John Gates invented the high-performance belt in 1917, the high-performance V-belt, like their timing belt cousin, has undergone tremendous technological development. A series of high-performance V-belts that are highly application-specific and provide distinct performance levels.

  In this article, we will review some of the basics of high-performance V-belts to help you better understand which belt to use in a given application, so that the belt drive can last longer, operate more efficiently, and Save downtime and money.

  Size is not everything

  However, please pay attention to the differences in cord material, host compound, cover layer configuration, temperature range and application requirements. Although they are similar in appearance, each belt is designed for a different purpose. Using the wrong belt may cause equipment damage or serious safety issues. What is the right belt for work? It depends on the application. The following are some of the environmental and application design standards that will affect belt selection:

  Ambient temperature

  Oil resistance

  Ozone resistance

  Electrostatic conductivity

  Power capacity

  Pulsation or shock load

  Small pulley diameter

  Back idler

  Eccentric tolerance

  Serpentine or quarter turn layout

  Minimum take-up

  pay close attention

  High speed

  energy efficiency

  Dust and abrasive

  As you can see, there are many factors to consider before choosing the right high-performance V-belt for the job.

  Generally speaking, high-performance V-belts can be divided into the following categories:

  Ambient temperature

  Heavy burden

  industrial machinery

  Continuous operation

  Heavy objects and often harsh conditions

  relaxing work

  Low power application

  Intermittent use

  Automobile industry

  The working principle of high-performance V-belt

  Unlike flat belts that rely solely on friction and can track and slide off the pulleys, the side walls of the high-performance V-belt can be fitted into the corresponding pulley grooves to provide a larger surface area and higher stability. When the belt is running, the belt tension will exert a wedging force perpendicular to its top, pushing its side wall to the side of the pulley groove, thereby multiplying the friction force, so that the drive can transmit higher loads.
