ZP275转盘设计 [摘要]转盘是石油钻机的提升设备之一，在钻井作业中，主要用于旋转钻杆柱，在起下钻和下套管时，支撑井下的钻柱（或套管柱）重量。转盘可用于链条传动，也可用于万向轴传动。 本文对ZP275转盘的基本结构，详细尺寸进行了设计，ZP275转盘主要由转台装置、铸焊底座、输入轴总成、锁紧装置、主补心装置、上盖等零部件组成。本文介绍了ZP275转盘设计理论与计算方法，通过转盘的基础参数，对一些主要的零件进行了计算，强度分析和材料的选用。主要包括，齿轮副的计算和强度校核，轴承的选用与计算，强度校核，轴的结构设计，联接件的强度校核。用SolidWorks和CAD绘制了总装配图，轴承图和齿轮图。然后对ZP275转盘的安装使用及其调整进行了详细的介绍，对密封润滑、运输方面提出了建议，最后确定ZP275转盘的整体结构。 [关键词]转盘密封润滑强度校核轴承 Desig
