The tapered roller bearing has great influence on rotary machine with high load,and hollow roller bearing is applied in significant engineering right now.According to Hertz contact theory and FEM,the equivalent three- dimensional simulation model of single roller-ring solid and hollow tapered roller bearing is established in ANSYS separately,the influence rule of various hole rate and load on elastic deformation and contact stress etc is analyzed.As a result,contact stress value is verified by theoretical calculating result.Simultaneously,the analysis one affords reference for optimal design and engineering application of tapered roller bearing.
