This tool allows the calculation of multi-layered interference fits considering thermal expansion and centrifugal forces.
The inner diameter for the inner section can be defined on top of the window, each section then only has the outside diameter as input. Also an internal pressure can be defined on the inner layer and an external pressure on the outer layer. The interference is an additional input for each layer and is not determined by diameters.
If a friction coefficient and a width are defined, then a maximal permissible axial force and torque are shown on the last two rows.
