针对现有锥螺杆-衬套副曲面成形方法复杂、难于实现成型加工等问题,提出了一种基于平面截面圆和圆柱螺旋线的锥螺杆-衬套副曲面成形方法,并通过空间啮合理论,建立了锥螺杆-衬套副的螺旋曲面方程。系统地研究了其空间接触特性及其密封机理,并通过运动仿真分析验证了锥螺杆-衬套副运动过程中不存在轴向位移的理论。研究结果表明:提出的锥螺杆-衬套副曲面成形新方法具有数学建模简单、便于数值计算和曲面成形加工的优点,有利于提高锥螺杆-衬套副的空间接触特性和密封性能,以便使其满足容积式海水液压泵的工作条件。

The complex surface building method of the existing screw-sleeve pair goes against the moulding process. According to the problem, a surface building method of the pair based on circular cross section and cylindrical helix was investigated, the surface equation of cone screw and sleeve was established based on the space meshing theory. The contact characteristics and the sealing mechanism of the pair were systemmatically studied. The theory without axial motion during the movement of the screw-sleeve pair was verified by motion simulation. Analysis show that the new surface building method makes the mathematical modeling easier, which is favorable to numerical calculation and moulding process. With good contact characteristics and sealing performance, the screw-sleeve pair built by this method will meet the working condition of the cavity type seawater hydraulic pump.
