It’s a good idea to replace the belts on pulleys once a year to ensure they’re performing at their best. The V-Belt Pulley, also known as a sheave, is one of the fastest-growing and most commonly utilized product types in the Power Transmission and automotive industries.

V belt pulley measurement is straightforward; nevertheless, there are many various types and alternatives when it comes to properly identify a v-belt pulley.

Belts are not measured by their diameter or when they are folded in half. A v belt measurement instrument or a cloth tape measure is the most precise way to measure the circumference of a v belt (Not a steel tape measure or ruler).

Wrap a tiny diameter string/rope around the belt and measure the length of the string as an alternative. Make sure the belt is under slight stress and the fabric tape measure is tightly against the back of the belt when measuring.

Also, keep in mind that belts stretch, and there is no set measurement for how much a belt can stretch. To figure out the portion v belt you have, you’ll need to measure the width and depth.

To measure industrial V Pulley one can also follow the below steps:

  • The first thing you should do is measure the pulleys outside diameter (O.D).
  • Next, we’ll take a measurement of the pitch diameter (P.D.), which is the diameter of the belt itself as it rides in the pulley. If you already know your v-belt size or if the pulley and belt are severely worn, skip this step.
  • Next, determine the pulley’s wall thickness.
  • The whole width of the “belt housing,” which is where the belt actually travels in the pulley, should be measured.
  • It’s usually a good idea to measure the hub extension if the pulley’s hub extends beyond the “belt housing” width.
  • The entire width of the pulley is the ultimate measurement. In most cases, this will indicate the belt type or series that was utilized.

V-belts were invented to increase belt dependability and torque transmission from the crankshaft to rotating components in the early days of automotive development. V-belts are still a popular serpentine belt today.

V-belt transmissions are a significant improvement over round or flat belt transmissions; they offer superior traction, speed, and load capabilities while having a long service life and easy repair. Heavy loads improve transmission efficiency by wedging the belt deeper into the groove of the pulley, reducing friction.
