The Stress Analysis about Rolling-Sliding Blend Bearing under Heavy Load

Article Preview

Abstract:

In the paper a new kind of rolling-sliding blend bearing has been studied. In order to comparing the new bearings and rolling bearings in the carrying capacity and service life, the stresses on the inner ring, the outer ring and the roller of rolling bearing and rolling-sliding blend bearing are analyzed by establishing the finite element model and solving it with finite element analysis software. The results show that the width of the stress concentration area on the outer ring and the roller and the inner ring of rolling-sliding blend bearing is 25 per cent narrower than that of rolling bearing and the depth of the largest stress on the outer ring and the roller and the inner ring of rolling-sliding blend bearing is 25 per cent shallower than that of rolling bearing and the largest stress on the middle and the end of the outer ring and the roller and the inner ring of rolling-sliding blend bearing is much smaller than that of rolling bearing. In the same case rolling-sliding blend bearings have greater carrying capacity and longer service life than rolling bearings.
