运用ANSYS软件,对φ850轧机轴承座不同承载厚度值进行了有限元模拟分析,得出了轴承座接触应力随轴承座承载厚度变化的规律。在考虑安全系数及轴承变形等因素的情况下,选取轴承座孔承载厚度值,为轧机轴承座的使用提供了理论依据。 By using ANSYS software, the finite element analysis of different bearing thickness of φ850 rolling mill bearing was carried out, and the rule that the contact stress of bearing was changed with the bearing thickness was obtained. Considering the factors of safety factor and bearing deformation, the thickness of the bearing seat hole is selected to provide a theoretical basis for the use of the rolling bearing seat.
