For solid cylinders ofa given weight, WK 2 isestimated from the formula:3. For solid or hollow cylinders, the inertia is calculated by the following equations:Solid CylinderHollow CylinderWK 2 = .000681 p LD 4WK 2 4= .000681 p L (D 2 _ 4 D1 )DLWK 2 = W ( R2 )2WK 2 = lb ft 2Where: D, D 1 , D 2 , L = InchesP = lb/in 3Where: P (Aluminum) = .0924P (Cast Iron) = .260P (Steel) = .282Calculate the inertia of complex, concentric, rotating parts by breaking the part intosimple cylinders, calculating their inertia and summing the values of each.= + +Where: WK 2 = inertia in lb. ft. 2R = cylinder radius in ft.W = weight in lbs.In applications where the speed of the load is different from the speed at the clutchor brake, the value of WK 2 is referred to as reflected inertia.DL◗ TORQUEEnglishCalculate the required torque. Estimate the torque requirements basedon the rated horsepower of the prime mover.T =63000(HP)KRPMT = torque in in. lbs.HP = horsepowerRPM = Speed at clutch or brakeIf the driven load has heavy rotating parts that must be started orstopped in a specific time, evaluate the torque from the formula:T = .039 (WK2 )∆RPMtT = average torque in in. lbs.WK 2 = total inertia load in lb. ft. 2RPM = initial RPM – final RPMt = time in seconds for ∆RPMThe time (t) in seconds required to accelerate or deceleratea rotating mechanism is estimated as follows:t = .039 (WK2 ) RPMTt = required starting or stopping timeWK 2 = total inertia load in lb. ft. 2PRPM = speed at the clutch or brakeT = rated clutch or brake torqueMetricT =P(9545)KnT = torque in Newton meters (Nm)P = transmitted power in kilowatts (kW)n = speed at clutch or brakeIf the driven load has heavy rotating parts that must be started orstopped in a specific time, evaluate the torque from the formula.T =(J)∆nt(9.55)T = average torque in Newton meters (Nm)J = total inertia load in kgm 2∆n = initial RPM – final RPMt = time in seconds for ∆nThe time (t) in seconds required to accelerate or deceleratea rotating mechanism is estimated as follows:t = (J) n(9.55)t = required starting or stopping time in secondsJ = total inertia load in kgm 2∆n = speed at the clutch or brakeT = rated clutch or brake torqueNOTE — A service factor (K) is required to determine the actual torque that the clutch must deliver. For example, some electric motors will deliver three times their rated horsepower for ashort period of time. The clutch or brake must be capable of handling the maximum possible output.NOTE — Torque increases as the speed decreases. Mount the clutch on the highest speed shaft available.363
