摘　　要：介绍了目前钻井泵常采用的整体铸造式、整体锻造式、组焊式、组装式4种结构形式。组装式曲轴可避免整体铸造、整体锻造及焊接等带来的诸多问题,被越来越多的钻井泵设计者所采用。确定芯轴和偏心轮之间合理的装配过盈量是组装式曲轴设计的关键点和难点。应用ANSYS软件的非线性接触分析功能,计算出某新型组装式曲轴的芯轴与偏心轮之间合理的装配关系为H7/t6,可供同类设计参考。Four types of frequent crankshafts are introduced：whole casted,whole forged,assembly welded,and assembly crankshaft.The assembly crankshaft is being adopted by more and more pump engineers because it can avoid many other type crankshafts＇ problems.It is critical and difficult for assembly crankshaft designing to determine apposite interference value between central shaft and eccentric wheel.ANSYS＇nonlinear contact analysis function was used to calculate some new type crankshaft＇apposite assemble relationship between central shaft and eccentric wheel is H7/t6.It may be a reference in similar designing.
