A contact analysis for unconventional mounting processes of angular ball bearings
International Journal of Mechanics and Materials in Design, 2023 AbstractRigorous protocols must be followed when mounting ball bearings to avoid structural damage and subsequent malfunctioning or unexpected failures. Unconventional mounting procedures may produce excessive contact pressures between the elements of the bearing, therefore the whole process must be well-understood and modelled to prevent unwanted ...
