材料和衬套厚度对水润滑阶梯腔尾轴承力学性能有限元分析

摘要

建立不同材料和不同衬套厚度的水润滑阶梯腔动静压尾轴承三维实体模型,并用Workbench软件进行有限元力学性能分析.结果表明:轴承材料和衬套厚度对尾轴承的力学性能有比较大的影响.当尾轴承的外圈材料是45#钢,衬套材料为硬橡胶时,轴承具有较好的柔性和最优的力学性能;在设计尾轴承结构时,橡胶层厚度选为20 mm,则不仅具有较好的力学性能,而且还能够节省成本.%Setting up different material and different thickness of the liner of water lubricated ladder dynamic and static pressure cavity stern bearing three-dimensional model, and analyzing mechanics performance by Workbench software. The results show that bearing material and thickness of the liner have an influences on the stern bearing larger mechanical proper-ties. When the stern bearing outer ring material is 45#steel, and bush material is hard rubber, and bearing has good mechanic-al properties of the flexible and optimal; The rubber layer thickness of 20 mm, not only has good mechanical properties, but also can save cost, when designing the stern bearing structure.
