How To Measure V Belt Pulley?

Summary

To measure a V-belt pulley, begin by determining the pulley's pitch diameter, which is the diameter of the circle formed by the tops of the V-belt's teeth. Measure this diameter using a caliper or ruler. Next, calculate the outside diameter by adding the pulley's pitch diameter to twice the depth of the V-belt groove. Finally, measure the bore diameter, which is the diameter of the hole in the center of the pulley.

One of the growing and most widely used product types in the power transmission and automotive industries is the V-belt pulley, also known as a "pulley.". A V-belt pulley is an accessory that transfers energy between shafts with the aid of a V-belt. However, in order to keep this important pair of equipment running properly, when the old equipment wears out, it is necessary to ensure that the proper V-pulley is replaced. To do this, you need to know the size, dimension and type of your V-pulley so that the replacement will function properly. It is a simple task to learn how to measure a V-belt pulley and calculate its dimensions.

Step 1

Measure the outside diameter of the pulley.

Step 2

Then measure the pitch diameter. This measurement represents the diameter of the belt itself as it runs in the pulley. If you already know the size of the V-belt, or if the pulley and belt are badly worn, you do not need to perform this step.

Step 3

Measure the wall thickness of the pulley.

Step 4

Measure the total width of the belt housing, where the belt actually runs in the pulley.

Step 5

If the pulley has a hub that extends beyond the width of the "belt housing," it is often best practice to measure the extension of the hub.

Step 6

The final measurement is the entire overall width of the pulley. In most cases, this will specify the type or series of belt used.
