Abstract

Taking a cylindrical roller bearing as a research object, the contact stress between the cylindrical roller and the outer ring raceway with a taper error is studied by means of ANSYS in order to obtain the allowable value of the upper bound of the taper error. The results show that the given load corresponds to the suitable upper bound of the taper error of the outer ring raceway and with the increasing taper error, the contact stresses between the cylindrical roller and the outer ring raceway increase observably and the distribution of the contact stresses presents more complex asymmetry and nonuniformity.
