Read the deflection force value (N) on the Newton scale by taking reading at the lower side of the upper ring.Ĭompare the deflection force value (N) with the values given in the following table 1 on page 38. Apply force with the help of Tension Tester perpendicular to the span till the lower surface of the ring touches the string. Place Tension Tester at the centre of the span of the belt. Adjust lower side of the upper ring at 0.00 N. Adjust lower ring on the Tension Tester on mm scale to coincide ‘x’ mm with the lower side of the ring. Tie a string / thread on the two pullies along the length of belts and mark centre of the span on the belt.Ĭalculate 1.5% of the span (say 'x') for the belt length less than 1000mm & 1% of the span for belt length more than 1000mm. Measure the span length of the belt in mm (Ref.sketch) The belt tension in most drives can be checked with adequate reliablity by means of PIX V-belts Tension Tester. To ensure optimum V-belt drive operation, it is recommended to check the tension in the belts by measuring the deflection force value (N) with the help of a tension measuring device. Proper belt tension is vital to the operation of drive and the life of V-belts. General guidlines for tension measurement of V-belts) ![]()
