4.0 - TORQUE
Rated output torque
T n2 [in·lbs]
This is the torque output the gearbox can deliver safely, based on:
• uniform loading and service factor S.F.= 1
• 10000 hours theoretical lifetime
Maximum torque
T 2max [in·lbs]
The output torque the gear unit will withstand in a static condition or a highly intermittent operation.
It is generally meant as a momentary peak load or starting-up torque under load.
Required torque
Tr2 [in·lbs]
The torque drawn by the application. It must always be equal to or less than rated output torque
«T n2 »forthegearboxunderstudy.
Calculated torque
T c2 [in·lbs]
Computational torque value to be used when selecting the gearbox, considering required torque
«T r2 »andservicefactor«S.F.».
It is obtained through the equation:
T c2 T r2 S.F. T n2

5.0 - HORSEPOWER
Rated input power
P n1 [HP]
«P n1 » is the horsepower that can be safely applied to the gearbox when the same is operated:
• at rated speed (values listed for n 1 = 1750, 1450, 1150 and 870 rpm)
• under service factor S.F. = 1
• yielding a theoretical lifetime of 10000 hours.
