摘要:

目前,单螺杆式水力机械螺杆-衬套副的断面齿廓有短幅内摆线型和短幅外摆线型两种。本文论述了上述两种摆线型螺杆-衬套副的啮合理论,然后以此为基础,重点研究了螺杆-衬套副的作用力问题,包括螺杆所受的总轴向力及其三个分量(端面轴向力、液压差轴向力和正压力铀向力);倾倒力矩;横向力等。所获得的结论对单螺杆式水力机械的设计计算和科研工作有一定的参考价值。

Abstract:

In this paper,the dynamic loads on the screw in a screw-liner pair with cross-sectional profiles of hypotrochoid or epitrochoid type of singlescrewed hydraulic machinery have been studied.The engagement theory,specifically the exact theoretical expressions of the axial forces,overturning force and overturning moment,transverse force etc are given.The findings are useful in design and research of single-screwed hydraulic machinery.
