Where is the load carrying section of a v-belt situated?

The load-carrying section of a v-belt is situated on the neutral axis. This is because the neutral axis is the point within the belt where there is no tensile or compressive stress when the belt is in operation. It is the part of the belt that experiences the least amount of distortion and can effectively handle the tension generated by the load being transmitted.

When a v-belt operates in a pulley system, it has a trapezoidal cross-section, with the sides of the belt pressing against the pulley grooves. The load-carrying components of the belt — where the actual load is supported — align along this neutral axis, allowing for efficient transfer of power and load without excessive wear or stretching of the belt material.

Understanding the location of the load-carrying section is crucial for proper belt selection, installation, and maintenance, ensuring optimal performance and longevity of the belt in mechanical systems.
