Abstract

Joint bearing can make spherical motion in a certain angle range because the contact surface is spherical in shape. And the clearance of the joint bearing is necessary for the bearing to realize oscillation, tilting and rotating motion. In order to determine the best original clearance of the joint bearing, simulation analysis of the joint bearing under different original clearances is carried out based on the theoretical calculation analysis of the mating clearance. The analysis results show that when the clearance between the inner and outer rings increases, the maximum contact stress between the inner and outer rings of the bearing increases. Under the premise of satisfying the original clearance, mating clearance and working clearance of this spherical bearing, the clearance value of this model of spherical bearing is selected as the smaller clearance in the clearance range.
