The Finite Element Analysis Of Split Cylindrical Roller Bearing

Split cylindrical roller bearings as mechanical basis of important oneof the links, are widely used in many fields. Its running state will directly affect theoperation of the whole mechanical system. Therefore, in order to meet the need of theproduction of a new generation of advanced machinery and equipment, it is important tosimulate the bearing.In this paper, split cylindrical roller bearing as the research object, established athree-dimensional contact model and the model of the whole profile roller bearings andcylindrical roller bearing was carried out to determine the model, unit selection,meshing, contact parameters, boundary conditions. Using the finite element methodanalysis of roller contact stress, and split cylindrical roller bearings under a certain load,the effect of different rotate speed of the bearing, and split cylindrical roller bearings incertain speed conditions, effects of different load on the bearing. And the ordinarycylindrical roller bearings are the same analysis, will split cylindrical roller bearings andcylindrical roller bearings are analyzed. Analysis on speed, under certain conditions,deformation and equivalent bearing radial load bearing the greater the greater the stress;In the condition of bearing load, the stress and strain also increases with increasing thebearing speed equivalent. Roller and an inner ring and outer ring contact stress ratioroller contact stress; The maximum stress on the inner and outer rings below the surfaceof roller and bearing inner and outer ring contact, not directly on the outer ring surface;The maximum stress can lead to contact surface to crack and then extend to thecontacting surface, can lead to long-term bearing fatigue peeling. The outer ring of thestress is small, almost no obvious strain; deformation is the most obvious inner force, sothe inner most easily damaged during bearing operation. The results are consistent withthe actual situation. Has extensive reference significance of this study to solve similarproblems in engineering.
