T_2N values are calculated at n₁=n_1n, continuous duty cycle, uniform operation and KA=1 according to ISO 6336. T_2N(1.2M) has been calculated for 1200000 revolutions of the output shaft, and T_2N(6M) has been calculated for 6000000 revolutions of the output shaft. The application factor KA according to DIN-3990-1 must be considered for each duty cycle and machine type.
T_2Peak is the maximum output torque the gearbox can tolerate during startups, inversions or other peaks. This value should never be used for continuous operation or for intermittent operation with frequent accelerations.
n_1N is the rated input speed for continuous operation
n_1Max is the maximum input speed for intermittent service. For continuous operation at speeds over n_1n please inquire
