适当的皮带张力对于最佳的动力传输以及延长皮带使用寿命至关重要。为确保最佳多楔带传动操作,建议在张力测量装置的帮助下测量偏差力值 (N) 以便检查皮带张力。通过 PIX 拉伸试验仪可以确保大多数驱动器的皮带张力达到足够的可靠性。

Tension Measurement Procedure

  1. Measure the span-length of the Belt in mm. (refer below sketch drawings)
  2. Tie a string or a thread on the two pulleys along with the length of the Belt and mark the center of the span on the Belt.
  3. Calculate 1.5% of the span (say ‘x’) for Belt length less than 1000 mm and 1.0% of the span for Belt length more than 1000 mm. Adjust lower ring on the tension tester on the millimeter scale to coincide, "x" mm with the lower side of the ring. Adjust lower side of the upper ring at 0.00 N.
  4. Place tension tester at the center of the span of the Belt. Apply force with the help of tension tester perpendicular to the span, till the lower surface of the lower ring touches the string.
  5. Read the deflection force value (N) on the Newton scale by taking reading at the lower side of the upper ring.
  6. Compare the deflection force value (N) with the values given in the Table 'A'. The deflection force value (N) should lie between the minimum and maximum values given in the Table 'A'. (Next page)
  7. Deflection force less than the minimum recommended value in the range indicates an under-tensioned drive & deflection force higher than the maximum recommended value indicates an over-tensioned drive.

Important:

  1. For new Belts the deflection force value (N) should be kept at maximum.
  2. Maximum deflection force value (N) is recommended for pulsating & shock loads.
  3. It is recommended to re-check the Belt tension after approximately 24 hours of running and adjust the tension, if necessary.
