摘　　要：利用proE在数控深孔螺旋拉床整机设计中建立模型,并依靠其组件mechanica对设计中的关键零件进行分析。在机床某些零件的设计中需考虑变因素,如主轴联轴器处的变形。由于在设计中要求拉杆穿过主轴内部,而主轴尾部需要使用依靠挤压变形传递扭矩的联轴器,太大的间隙致使拉杆外径一定的情况下主轴内孔壁变薄,太小间隙则使主轴和拉杆也被挤压到一起,经过分析则可以得到优化后的间隙选择。Use proE to establish model in NC deep hole helical broacher design. Then, based on the mechanica, analyze the key parts, and certain parts of machine need to consider variable, such as the coupling component distortion of principle axis. During the process, shaft needs to through the principle axis and the end of principle axis needs coupling component distortion of principle axis. The oversize clearance will thin the principle inner hole wall based on certain shaft outer diameter. The small clearance will crush the principle axis and shaft. After analyzing, acquire the optimal clearance selecting.
