Proper belt installation and tensioning and sheave alignment are essential in order for a facility to function at optimum efficiency.
A key thing to understand when it comes to belts is proper sizing. Whether you are using a correctly-sized belt for your machine will have a significant impact on the machine’s ability to function at an optimal level.
A simple cloth tape measure can be used to measure belt size. It’s also important to remember that belts of different sizes should not be interchanged.
You can also use a mathematical equation to calculate the length of the belt. First, you will need to know the values of the following:
You can then take the pD and multiply by 3.14, divide by 2, and add to the pd multiplied by 3.14 again and divided by 2, then add 2 times the distance between the driving and driven shafts: this will also give you the belt length.
A couple tools you will want to have on hand when checking belts and sheaves:
Remember, in order to avoid:
You will want to ensure that your belt and sheave are aligned correctly. An easy-to-use tool you can utilize for this purpose is the Belt Hog from VibrAlign. With the Belt Hog, there is no need to remove belts, and one person can quickly and accurately check the alignment.
