Service Factor for Clutch Solution

STEP 0: Pre-Calculation Summary

Formula Used

Service Factor for Clutch = Torque Capacity for Clutch/Rated Torque of Friction Clutch
K_s = Mt_r/M_Trated
This formula uses 3 Variables

Variables Used

Service Factor for Clutch - The Service Factor for Clutch is defined as the ratio of the torque capacity and the rated torque value of a clutch.
Torque Capacity for Clutch - (Measured in Newton Meter) - The Torque Capacity for Clutch is defined as the product of rated torque and service factor of the clutch.
Rated Torque of Friction Clutch - (Measured in Newton Meter) - Rated Torque of Friction Clutch is the torque that is rated for the friction clutch.

STEP 1: Convert Input(s) to Base Unit

Torque Capacity for Clutch: 47000 Newton Millimeter --> 47 Newton Meter (Check conversion here)
Rated Torque of Friction Clutch: 27640 Newton Millimeter --> 27.64 Newton Meter (Check conversion here)

STEP 2: Evaluate Formula

< 10+ Basics of Friction Clutches Calculators

Coefficient of Friction of Clutch given Friction Radius

Go Coefficient of Friction Clutch = Friction Torque on Clutch/(Axial Force for Clutch*Friction Radius of Clutch)

Friction Radius of Clutch given Friction Torque

Go Friction Radius of Clutch = Friction Torque on Clutch/(Coefficient of Friction Clutch*Axial Force for Clutch)

Axial Force on Clutch given Friction Radius

Go Axial Force for Clutch = Friction Torque on Clutch/(Coefficient of Friction Clutch*Friction Radius of Clutch)

Friction Torque on Clutch given Friction Radius

Go Friction Torque on Clutch = Coefficient of Friction Clutch*Axial Force for Clutch*Friction Radius of Clutch

Rated Torque of Clutch given Torque Capacity

Go Rated Torque of Friction Clutch = Torque Capacity for Clutch/Service Factor for Clutch

Torque Capacity of Clutch

Go Torque Capacity for Clutch = Service Factor for Clutch*Rated Torque of Friction Clutch

Service Factor for Clutch

Go Service Factor for Clutch = Torque Capacity for Clutch/Rated Torque of Friction Clutch

Friction Radius of Clutch given Outer and Inner Diameter

Go Friction Radius of Clutch = (Outer Diameter of Clutch+Inner Diameter of Clutch)/4

Inner Diameter of Clutch given Friction Radius

Go Inner Diameter of Clutch = (4*Friction Radius of Clutch)-Outer Diameter of Clutch

Outer Diameter of Clutch given Friction Radius

Go Outer Diameter of Clutch = (4*Friction Radius of Clutch)-Inner Diameter of Clutch

Service Factor for Clutch Formula

Service Factor for Clutch = Torque Capacity for Clutch/Rated Torque of Friction Clutch
K_s = Mt_r/M_Trated
