Determine the keyed joint / interference fit parameters to transfer the torque between a shaft and a hub.

Main operations

  • Finite-elements modelling of the assembly: shaft, hub, key.
  • Definition of nonlinear friction contacts between the parts.
  • In the case of an interference fitted assembly, consideration of the tighten adjustment between the hub bore and the shaft outer diameter.
  • Nonlinear static calculation under the load of torque to transfer
  • Analysis of the mechanical constraints on the shaft and the hub
  • Analysis of the shear stress and the mating pressure on the key
