Numerical Simulation Research on the Crowned Design by Multiple-variable-curvature Arcs for Cylindrical Roller Bearing
Based on finite element software MSC.Marc, the specific simulation model of cylindrical roller bearing was established, the axial equivalent stress distribution corresponding to Lundberg theoretical logarithmic crowned type was analyzed. Through the results of contact-mechanics properties and by means of design innovation, it is put forward that the Lundberg theoretical logarithmic crowned type can be replaced approximately by the multiple-variablecurvature arcs to avoid the stress concentration on the ends of roller. The influence of arc number on the axial equivalent and contact stress distribution was analyzed using finite element simulation. According to the numerical research, the appropriate number of curvature-changing arc segments was proposed. This method can be applicable to other types of line contact and the crown design of the roller.
