This procedure creates an example using the sample specifications.
Sample Data:
- Required Torque: T = 40-lb ft
- Clamping Factor: ν = 0.08
- Type of Loading: static
- Shaft Diameter: d = 1 in
- Hub Length: L = 1.5 in
- Number of Joint Bolts: N = 4
- Material: steel grade 37

- Start the Separated Hub Joint Calculator.
- On the Calculation tab:
- In the Type of Strength Calculation, select Check Calculation.
- In the Load area, enter Torque = 40.
- In the Dimensions area, enter Shaft Diameter = 1.
- In the Joint Properties area, click the button next to the Material edit field, and select the material and type of loading from the database. Enter Clamping Factor = 0.08.
- In the Bolt Properties area, enter Number of Joint Bolts = 4.
- Click Calculate to perform a separated hub joint strength check. The optimum hub length is based on minimum hub length, joint strength, pressure values, and axial force in bolts.
- Click OK to insert separated hub joint calculation to the Autodesk Inventor Assembly.
