摘　　要：型腔尺寸的大小和腔数对水润滑橡胶尾轴承的力学性能有重要影响,并且直接影响轴承的承载能力和运转精度。本文基于有限元法,研究了不同型腔数目、型腔全角和型腔长度对尾轴承的力学性能影响。结果表明:在5种不同腔数尾轴承的研究对比中发现,4腔尾轴承的力学性能最优。研究型腔全角和长度因素影响时,发现全角55°长度500 mm的型腔结构性能更好。Cavity size and the cavity number have an important influence on the mechanical property of water lubricated rubber stern tube bearing, and affect the bearing capacity and running accuracy directly. The effect of different number of cavity, cavity full angle and cavity length on mechanical properties of stern bearing was studied based on the finite element method in this paper. The results show that the mechanical properties of 4 cavity stern bearing is the best compared with the other five different cavity stern bearings. It was found that cavity structure performance of the angle of 55 and the length of 500 mm is better than others.
