Tighten the bolts alternately sleeve pulley until the sleeve and pulley release. 3. Remove the sleeve and the pulley from the shaft. Pulley drive pulley ratio is how to calculate the efficiency ratio determines the pulley, a pulley and efficient power transmission lines need to hold good pulley, the pulley in the choice of when to pay attention to transfer power, many people do not know how to count the power transmission Bushes specifications below Jiaojiang fine art machinery factory to tell you about. Transmission ratio is calculated as i = Dl / D2 = n2 / nl where: i: transmission ratio; Dl: capstan (power machine pulley) mm; D2: driven wheel (water pump pulley) mm; n1: Active rotation number (turns / points); n2: passive rotation number (rev / min); When using flat belts, transmission ratio i is determined: the opening drive. i <5, or prone to slipping.
