How To Measure A Belt Pulley. How to calculate belt length. Proper selection of a conveyor pulley when selecting a pulley for a belt conveyor application, specifications will be determined by addressing the following steps:
For example an 80 tooth pulley would have an 8” outside diameter (o.d.) (80 teeth / 10) or a 33 tooth pulley would have a 3.3” outside diameter (o.d.) (33 teeth /. Rotate the v belt to place the paint mark against the flat surface. Step 1 the face length of the conveyor pulley step 2 the anticipated belt tension of the conveyor system step 3 the outer diameter & shaft diameter of the conveyor pulley
Obtain the circumferences of both the driver pulley and the driven pulley by measuring the radii of both pulleys.
This means you would measure the widest part of the belt (thick section) and then from the widest part to the narrowest part of the belt. Or use the second calculator to figure the distance between two pulleys. Set the flat outer edge of the v belt on a flat surface. Under load, the belt will be under a maximum tension of 9.1 pounds on the tight side, and a minimum tension of only 4.3 pounds on the.
