Ratio ( i = N in / N out )
Backlash is measured at 2% of Nominal output torque T_2N.
These values are measured by gearbox with ratio = 10 (1-stage) or ratio = 100 (2-stage) at 3.000 rpm without load..
Applied to the ourput flange center at 100 rpm.
These values are measured by gearbox with ratio 10 (1-stage) or ratio 100 (2-stage) at 3,000 rpm no loading.
By lower ratio and/or higher rpm, the noise level could be 3 to 5 dB higher.
