摘　　要：对单螺杆泵定转子的螺旋曲面表面进行理论研究,在已知双参数摆线等距线方程基础上,通过已知内外摆线方程重新推导出了内外摆线等距线方程,并求出了此方程的不可微(即不连续)的点。此方程与现有一般摆线等距线方程相比,由双参数方程转化为单参数方程,将更利于型线的分析与改进。The article is the further research on the theory of spiral surface of single screw pump stator.Based on the equations on equidistant line of cycloid,the equations on equidistant line of hypocycloid and epicycloid are deduced when the equations of hypocycloid and epicycloid are known and the discontinuous point is solved.Compared to common equations on equidistant line,it turns into equation with single parameters from the one of double parameters,and this will be beneficial to the analysis and improvement on the profile line.
