- Case Studies
Higher torque ranges, actuation pressures, and stronger release springs are available to meet customer’s specific design requirements. Contact Logan for more details.
|Small Inertia Low Cycle Rate Non-pulsating Load||1.3 to 1.7|
|Large Inertia Low Cycle Rate Non-pulsating Load||1.7 to 2.2|
|Small Inertia High Cycle Rate Pulsating Load||2.2 to 3.2|

I Calculate the torque requirement for the application using one of the following formula
Torque (Lb./In.) = HP* 63025/RPM
Tc (Nm.) = HP* 9550/RPM
II Identify the service factor which best identifies your application from the suggested service factor table.
III Adjust the torque requirement using the selected service factor.
Gross Torque Capacity (T) / Safety Factor (SF)
T= Tc x SF or T=Tb x SF
IV. Determine if the model will:
1) Accommodate the shaft and key
2) Operate at the required speed
3) Fit within the available space
V. Determine the Drive Ring Mounting
Vl. Complete the Application Fact Sheet

HP = Horsepower
RPM = Clutch or Brake shaft speed
WR2 = Total inertia to be stopped (Ib.ft.2)
T = Required Torque (Lb./ Ft., Nm, Lb./in)
Tc = Clutch Torque (Lb./ Ft., Nm, Lb./in)
Tb = Brake Torque (Lb./ Ft., Nm, Lb./in)
t = Time to stop (seconds)
SF = Service Factor
HP = T(Lb./Ft.)*RPM /5250
Torque (Lb./Ft.) = HP*5250/RPM
HP = T(Lb./Ft.)* RPM / 63025
Torque (Lb./In.) = HP * 63025 / RPM
HP = T(Nm..) x RPM /9950
Torque (Nm.) = HP*9950/RPM
