石虎塘水电站水轮发电机组合轴承结构特点

摘要

The paper makes an introduction to the structure characteristics of combination bearing for hydro-genera-tor of Shihutang hydropower station. Through carrying out finite element analysis and calculation on stresses and de-formations of key bearing parts by computer software and optimizing the structure, the long-term safe and stable oper-ation of unit was achieved, which provides a practical reference for future design and manufacture of big-sized bulb tubular generator.%∶文章主要讲述石虎塘水电站的组合轴承结构特点，同时运用计算机软件对关键部件进行应力和变形的有限元计算分析，优化设计结构，从而达到机组长期安全、稳定的运行实绩，为今后大型灯泡贯流式机组的发电机设计及制造提供借鉴和参考。
