摘要

非圆行星轮系是非圆齿轮液压马达的核心部件。非圆行星轮系由于其节距曲线的动态变化而表现出明显的非线性和时变特性，这给其承载接触分析带来了一系列挑战。本文基于有限元分析方法，对非圆行星轮系的实际啮合行为进行了仿真，建立了非圆行星轮系的全齿接触模型。通过引入齿面啮合节点的啮合刚度，分析了啮合过程中接触轨迹、法向接触力、综合弹性变形、啮合刚度和加载传动误差的变化规律。研究了载荷和转速对齿轮加载接触特性的影响，揭示了非圆行星齿轮系加载接触特性的变化规律。研究结果对非圆行星轮系的动态接触分析具有一定的指导意义。

Research on loaded contact characteristics of planetary gear train for high-order elliptic non-circular gear hydraulic motor

Non-circular planetary gear train is the core component of non-circular gear hydraulic motor. The non-circular planetary gear train exhibits significant nonlinear and time-varying characteristics due to the dynamic changes of the pitch curve, which makes its loaded contact analysis face a series of challenges. In this paper, based on the finite element analysis method, the actual meshing behavior of the non-circular planetary gear train is simulated, and the whole tooth contact model of the non-circular planetary gear train is established. By introducing the meshing stiffness of the tooth surface mesh node, the variation law of the contact trajectory, the normal contact force, the comprehensive elastic deformation, meshing stiffness and loaded transmission error in the meshing process are analyzed. The influence of load and rotational speed on the loaded contact characteristics of gears is studied, and the variation law of loaded contact behavior of non-circular planetary gear train is revealed. The research results have certain guiding significance for the dynamic contact analysis of non-circular planetary gear train.

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
