Drive Considerations

There are a number of factors to be considered before selecting a particular belt style for a specific application. Two of the most important factors to be addressed are the type of drive configuration and the provisions for belt tensioning (or lack thereof). The first thing to look at is the number of belts required to satisfy the application requirements and the overall geometry of the belt path, including sizes and number of pulleys.

Type of drives:

  • Individual, single drive, two pulleys
  • Open, crossed drive and quarter turn (90 degree twist)
  • Multiple-Belt Groups or Sets
  • Multiple pulleys (serpentine), four pulley quarter turn (mule drive), multiple belts on common shafts with backside idlers, multiple belts common tensioning or fixed-center shafts.

The next considerations are the allowable space to accommodate belt width and the type of pulley on which the belt will run. Is the pulley face open or are flanges used to retain the guide belts? Are any pulleys crowned for guidance and belt tracking? If so, what type of crowning is being used and how severe is the crown? What is the face width of the open pulleys or what is the dimension between the flanges? These answers are required for proper belt selection.

Not all belts are designed to withstand running against flanges. Most types of flat woven endless belts will track well over a minimum of pulley crowning. If flanges are required, always use straight sides at 90 degrees to pulley face surface and maintain sharp corners, minimizing any rounding which causes the belt to climb the flange.
