Belt Tension Formula

Formula for belt tension Bob Is The Oil Guy

Oct 26, 2018 · The formula is: (Deflection of belt) = (0.25)*(span length of belt between the two pulleys where the force is applied)*(perpendicular force applied on belt midway between the two pulleys)/(belt tension) Force applied on belt will be roughly 10 lb when you push with your index finger but "calibrate" your index finger first. You should measure

Tension your belts at the speed of light!

When the free span of a belt is plucked, tapped, or struck it will vibrate at a frequency known as its "natural" frequency. The frequency is a function of the static belt tension, the belt mass, and the length of the free belt span according to the following relationship: T = 0.0104 * K * L2 * F2 Where: T = static belt tension (lbs)

Maximum belt tension. While the centrifugal tension (sigma_{cf}) acts equally throughout the belt during operation and the quasistatic tensions (sigma_t) and (sigma_s) are only present to this extent in the corresponding belt sections, the bending stress acts only during rotation around pulleys, with the largest bending stress acting on the smaller drive pulley (see figure above).

The part you don''t understand is that for a given belt tension, belt deflection is directly proportional to the vertical force applied. So, if the belt deflects 1/4 inch when you push with 10 lb of force, it will deflect 1/8 inch when you push with 5 lb, and it will deflect 1/2 inch when you push with 20 lb.
