# How To Measure Belt Size For Pulley

How To Measure Belt Size For Pulley. L is the distance between the pulley axles.; The general rule for measuring a man’s belt size is to take your pant size and add 2 inches.

If we need to calculate the distance between the centres of the two pulleys, then we can use the following calculations to approximate this. An additional option is to wrap a small diameter string/rope around the belt, then measure the. For example, if pulley 1 is 6 diameter, and spins at 1000 rpm, and you need to find pulley 2 size to spin it at 500 rpm, enter pulley 1 = 6, pulley 1 rpm = 1000, pulley 2 rpm.

### D 1 = Pitch Diameter Of Larger Pulley.

Without measuring the outside diameter, you won’t be able to choose a pulley with the right size. How do you measure the timing belt between two pulleys? To achieve the circumferential length, you take the total number of teeth and multiply that by the pitch measurement.

### Center To Center Distance Unknown.

When you choose a pulley with the wrong diameter, you are going to destroy the. L is the distance between the pulley axles.; The driven pulley is the reactive pulley to the driver.

### Secondly, You Get Your Tape Measure And Put It Around Your Pants Just Like You Put On A Belt.

It's an approximation of the one given above: We will need to know the diameters of the pulleys as well as the belt length. If you know any 3 values (pulley sizes or rpm) and need to calculate the 4th, enter the 3 known values and hit calculate to find the missing value.

### The Above Image Illustrates Which Dimensions We Need And Each Is Colour Coded To Half Make.

The first thing you should do is measure the pulleys outside diameter (o.d). Well get out the tape measure and the calculator. For example, if pulley 1 is 6 diameter, and spins at 1000 rpm, and you need to find pulley 2 size to spin it at 500 rpm, enter pulley 1 = 6, pulley 1 rpm = 1000, pulley 2 rpm.

### The Length Of A Synchronizing Belt, Also Specifically Referred To As The Pitch Length, Can Be Determined By The Total Circumference Of The Band Measured From The Row Of Pitches.

Hold the cloth tape measure against the length or width of the belt depending upon which measurement you need. Yes, you need to measure the od (outside diameter) of v belt pulleys. To figure out the portion v belt you have, you’ll need to measure the width and depth.
