How to Tension Belt Drives with your gates tension testers

Up to 30 lbs.
1. Measures the span length(t)
2. Position the lower of the two “0” rings using either of these method.
  1. On the scale reading “ Deflection inches”, set the “0” Ring to show a deflection equal to 1/64” per inch of span length(t)
  2. On the scale reading “Inches of Span Length”, set the “0” Ring to show a deflection equal to the inches of measured span length(t).
  Read the scales at the bottom edge of the “0” ring. Leave the upper “0” Ring in maximum “ down “ position.
3. At the centre of the span(t) apply force with the Gates Tension Tester perpendicular to the span, large enough to deflect one belt of a multiple belt set on the drive until the bottom edge of the lower “0” Ring is even with the tops of the remaining belts. For drives with only one belt, a straightedge across the pulleys will assure accuracy of positioning.
4. Find the amount of deflection force on the supper scale of the Tension Tester. The Sliding Rubber “0” Ring slides up the scale as the tool compresses — and stays up for accurate reading of pounds force. Read at the bottom edge of the ring ( Slide ring down before reusing).
5. Compare the deflection force with the range of forces recommended. If less than minimum recommended deflection force, belts should be tightened. If more than maximum recommended deflection force, drive is tighter than necessary. (Note : There normally will be a rapid drop in tension during the “run-in period” for V-belt drives. Check tension frequently during the first day of operation.)

  3. At the center of the span(t), apply force, with the Gates Tension Tester perpendicular to the span, large enough to deflect one belt of a multiple belt set on the drive until the bottom edge of the lower “0” Rings are even with the tops of the remaining belts. For drives with only one belt, a straightedge across the pulleys will assure accuracy of positioning.
  4. Find the amount of deflection force on the upper scales of the Tension Testers. Total force will be the sum of the readings on each of the two scales as the tool compresses —and stay up for accurate reading of edge of the rings. ( Slide the rings down before reusing )
  5. Compare the total deflection force with the range of forces recommended. If less than minimum recommended deflection force, drive is tighter than necessary.
    Note: There normally will be a rapid drop in tension during the “run-in period” for V-belt drives. Check tension frequency during the first day of operation.
