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.
