1. Determine the component force of the main drive system as the external load in the circumferential direction, radial direction and axial direction.
2. The force components are arranged in two directions parallel to the axial direction and perpendicular to the axial direction; that is, the axial force and the centripetal force,
3. According to the fulcrum balance condition of the shaft; find the supporting reaction force of each fulcrum; that is, the external load on the bearing,
4. According to the size and proportion of the centripetal force and the axial force of the support; determine the type of bearing suitable for accepting such external force,
5. These external forces are converted into the equivalent dynamic load applied to the bearing according to the inevitable rules; for the demand of bearing fatigue life accounting,
6, sometimes these external forces according to another rule; converted into the equivalent static load applied to the bearing; to check whether the bearing can occur forever permanent deformation.
