Interference fit is a type of model for nonlinear analysis with contact region in the contact surface.
For this, a tight interference fit is required between the inner ring of the bearing and the shaft.
Unfortunately, because most bearings are unable to handle both axial displacement and structural misalignment, it has not been feasible for hearings to be installed with an interference fit on both the inner and outer ring.
The most commonly used methods for creating this radial "clamping" force are interference fits, axially preloaded tapers, and radially preloaded slotted hubs.
The methods traditionally used to facilitate the connections of shafts and hubs can be classified into three types: material fit, which uses welding, soldering, or adhesives; positive form fit, which uses keys, splines, and polygon-shaped hubs or shafts; and friction fit, which uses interference fit, tapered forms, and shrink disks.
