摘　　要：阐述了方钻杆旋塞阀的工作原理,分析了旋塞阀的主要故障。用Pro/E对旋钮进行结构有限元分析,讨论了旋钮的变形、应力与应变的分布。将浮动套轴承用于旋塞阀,在旋钮处安装一浮动套轴承,将旋钮的滑动摩擦变为浮动套轴承的滑动摩擦,减小开关阻力,为新型旋塞阀的研制提供一定的理论参考。Working principle of kelly crock is elaborated, the main fault is analyzed. The construction is analyzed by the Pro/E, the distribution of the displacement, stress and strain are discussed. The floating ring bearing is used. The floating ring bearing is installed on the kelly crock, it can make the wear of the kelly crock from slipping to slipping of floating ring bearing, so the rotating resistance is decreased and theoretical reference is provided for the development of new kelly crock.

关 键 词：旋塞阀 PRO/E 浮动套轴承 故障分析
