in the case of perforated please note: the load-bearing width b 0 based on the number of per-forations which decrease cross sec-tions. staggered perforations in partic-ular can reduce the load-bearing width considerably. reduce the figure for the load-bearing width b 0 by a further 20 % to take tolerances for per-

lets say that you own a factory and you need to a v- length. the diameters of the pulleys are 15 and 30 cm, and you want the distance between them to be 1.5 meters. d l = 30 cm = 0.3 m; d s = 15 cm = 0.15 m; l = 1.5 m; input the values into the equation. note, that the units are not relevant as long as theyre the same for all ...

drive slippage can result in excessive pulley cover wear, take-up bounce, and possible breakage if the take-up bounces high enough. excessive sag occurs when the tension is low and the drops (sags) between the idlers more than normal. optimal sag is 1.0% - 2.0% of the center-to-center ...
