(It is ideal to calculate from the actual load applied to the belt.) ∙ Overload Factor (Ks)=Ko+Ki+Kr+Kh+Km Ko : Load Correction Factor (Table 14) Ki : Idler Correction Factor (Table 15) Kr : Speed Multiplication Correction Factor (Table 16) Kh : Operation Time Correction Factor (Table 17) Km : Start/Stop Correction Factor (Table 18) ∙ When converting the torque (Tq) into transmission power (Pd), calculate the applicable values by using the following expressions. Torque (Tq)=tqxKs Transmitting Power (Pd)=Tqxn/9550 Tq : Design Torque (N·m) tq : Transmission Torque Ks : Overload Factor Pd : Design Power (kW) n : Speed (rpm)
