摘要:

螺杆马达是螺杆钻具的动力总成,其截面线型直接影响自身的各项工作性能。良好的工作性能是螺杆马达的设计目标。为获得工作性能良好的螺杆马达,首先,根据螺杆马达的工作原理和结构特点,提出了其效率、密封腔可靠性和稳定性的评价准则。然后,通过建立螺杆马达流固耦合三维有限元模型,基于显式非线性瞬态动力学方法分析了短幅内摆线螺杆马达密封腔接触带的接触力在不同负载工况下的变化情况。最后,基于螺杆马达效率的评价准则,针对影响短幅内摆线螺杆马达效率的关键因素,设计了一种类圆弧线型螺杆马达,并通过数值模拟和实验证明了该螺杆马达具有较好的工作性能。结果表明:在相同的负载工况下,相较于短幅内摆线螺杆马达,类圆弧线型螺杆马达密封腔的稳定性和可靠性更好,且在较高负载工况下具有更好的工作性能。研究结果为后续高性能螺杆马达的线型设计奠定了基础。

关键词: 螺杆马达类圆弧密封腔流固耦合可靠性稳定性    
Abstract:

The screw motor is the power assembly of the screw drilling tool, and its cross-sectional shape directly affects its working performance. Good working performance is the design goal of screw motors. In order to obtain a screw motor with good working performance, the evaluation criteria of efficiency, sealing cavity reliability and stability were proposed according to the working principle and structural characteristics of the screw motor. Then, a three-dimensional finite element model of fluid-structure coupling of the screw motor was established, and the contact force change of the sealing cavity contact strip of the short-amplitude endocycloid screw motor under different load conditions was analyzed based on the explicit nonlinear transient dynamics method. Finally, based on the evaluation criteria for the efficiency of screw motors, a new screw motor with quasi circular-arc contour-pattern was designed to address the key factors affecting the efficiency of short-amplitude endocycloid screw motors, and the good working performance of this screw motor was proved by numerical simulation and experiment. The results showed that under the same load conditions, the sealing cavity of the screw motor with quasi circular-arc contour-pattern was more stable and reliable than that of the short-amplitude endocycloid screw motor, and it had better working performance under higher load conditions. The research results lay a foundation for the contour-pattern design of high-performance screw motors in the future.

Key words: screw motor    quasi circular-arc    sealing cavity    fluid-structure coupling    reliability    stability
