Select Drive Shaft Diameter
Select a standard drive shaft from the drive shaft table and check its torque rating and angle of twist rating against the application requirements.
If Transmitted Torque (Nm) < Maximum Drive Shaft Torque (Nm) & If Acceptable Angle of Twist (Deg.) for shaft length < Rated Angle of Twist for Drive Shaft (Deg.) then drive shaft diameter selected is acceptable.
Check Drive Shaft Critical Speed
For the unsupported shaft length calculate the drive shaft critical speed for the support conditions required.
If Shaft Speed (rpm) < Drive Shaft Critical Speed (rpm) then drive shaft selection and configuration is acceptable.
