How to measure V-belt 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.
