Steady-State Torque of a Coupling Equations

Steady-state torque (Ts) The torque used to select couplings should be based upon the following equations:

In SI units:

Steady-State Torque SI Units

In inch (imperial) units:

Steady-State Torque Imperial Units


TS = steady state torque used to select the coupling (SI, newton-meters; U.S., inch-pounds)

Pnormal = input power required by the driven machine at the specified normal operating point (SI, kilowatts; U.S., horsepower)

Nnormal = speed corresponding to the normal power (in revolutions per minute)

S.F. = service factor
