Design algorithm for generatrix profile of cylindrical crowned rollers

Design algorithm for generatrix profile of cylindrical crowned rollers

The cross-section of roller profile controls the pressure distribution in the contact area and radically affects the roller bearings basic dynamic load rating and rating lives. Today the most used roller profiles are the logarithmic profile and cylindrical-crowned (ZB) profile. The logarithmic profi...
