Belt Tensioning General Method This method of tensioning Synchronous belts should satisfy most drive requirements Step 1 Reduce the center distance so that the belt can be placed onto the sprockets without forcing or prying it over the flanges Step 2 Increase the belt tension until the belt feels snug or taut
belts after first tensioning You can use one of the following tools to check the belt tension 1 Gates belt tension tester Refer Figure 11 Page 7 recommended 2 Place the belt tension indicator on the top of the belt at the center of the span and apply a force perpendicular to the belt
The best method to find the exact source is to simply release tension on the belt and spin each pulley in the supercharger drive by hand A pulley or an accessory with a failed bearing should be obvious there should be discernable drag unevenness or wobble evident in the faulty component
Flat belts still find applications in machinery Conveyor belts are a common example During the 19th and early 20th century flat leather belts were often found driving machinery in factories and for conveying power from engines to farm machinery Such belts running over cylindrical pulleys quickly wander off the pulleys

How crowned pulleys keep a flat belt tracking Before Vbelts were invented machinery was usually powered through flat canvas belts running on crowned pulleys These flat belts stayed centered on pulleys without any guides or flanges The key to keeping them tracking centered on the pulleys is the use of quotcrowned pulleysquot
VBelts largest advantage over flatbelt drives is the utilization of wedging to increase the total friction between the belt and pulley without increasing the hub load or effective tension Tensioning a Vbelt will cause the tensile members of the belt to exert resulting force R on the body of the belt The body of the belt in turn exerts a
In order to gain the most life from a flat wire conveyor belt the amount of tension on the system should be kept to a minimum When the conveyor is not running the belt should not be under tension When driven the tension on the belt should be just enough to move the belt when fully loaded Over time this tensioning will stretch the belt
