【摘要】：随着液压技术的不断发展，对液压马达的种类和性能提出了更多和更高的要求。当实际工况需要马达有多个稳定转矩、转矩的输出时，现有的定量马达是不能实现的。针对这个不足，从马达基本原理出发，研制出了一系列基于双转子结构的新型液压马达。在双转子结构中，一个定子与两个转子分别相互配合，在不改变马达输入流量且没有复杂变量机构的条件下，这种新型马达通过不同输入进、出油口的连接可以输出多种不同的转速和转矩，实现了在一个壳体内，多个马达同步工作且相互独立的功能。如果当作泵来使用，则可以不用减压阀同时工作在不同压力下同时输出多种不同流量以满足系统需要，这样就可以在液压系统中节省泵、马达和阀的使用数量，同时节省了能量消耗。本文首先对等宽曲线双转子偏心壳转多速马达的结构和工作原理进行了详细的介绍，然后借助SolidWorks建立该马达的实体模型和动态运动过程。通过对马达运动特性的理论分析，建立了滚柱连杆的位移、速度、加速度数学模型，同时分析了等宽曲线双转子偏心壳转多速马达的扭矩特性，，建立了瞬时扭矩数学模型，并对其数学模型进行了模拟，得出了双转子马达的扭矩脉动规律。通过SolidWorks软件建立双转子马达的三维实体模型；对其物理模型在MATLAB中进行仿真分析计算，得到了连杆滚柱马达相应零件的速度和加速度仿真曲线。经过对这些仿真曲线的分析可以得到影响等宽曲线双转子偏心壳转多速马达运动学的因素。从而为设计出更合理的该马达提供依据。本文的研究为今后优化设计，进一步提高工作效率、降低生产成本、扩展运用范围提供较详细的依据，并为该马达未来的定型生产提供了较详细的理论依据。
[Abstract]:With the development of hydraulic technology, more and more requirements are put forward for the type and performance of hydraulic motors. When the actual working condition requires the motor to have multiple stable torque, torque output, the existing quantitative motor can not be achieved. In order to solve this problem, a series of new hydraulic motors based on double rotor structure are developed based on the basic principle of motor. In a two-rotor structure, one stator and two rotors cooperate with each other, without changing the input flow rate of the motor and without complex variable mechanism, the new motor enters through different inputs. The connection of the outlet can output a variety of different rotational speed and torque, and realize the function of synchronous and independent operation of multiple motors in one shell. If it is used as a pump, it is possible to work at different pressures without reducing the pressure and simultaneously output a variety of different flows to meet the needs of the system, thus saving the use of pumps, motors and valves in the hydraulic system. At the same time, the energy consumption is saved. In this paper, the structure and working principle of the multi-speed motor with double rotor eccentricity shell with equal width curve are introduced in detail, and then the solid model and the dynamic motion process of the motor are established by means of SolidWorks. Based on the theoretical analysis of motor motion characteristics, the mathematical models of displacement, velocity and acceleration of roller connecting rod are established. At the same time, the torque characteristics of eccentric shell and multi-speed motor with double rotor with equal width curve are analyzed, and the instantaneous torque mathematical model is established. The mathematical model is simulated and the torque pulsation law of double rotor motor is obtained. The three-dimensional solid model of the double-rotor motor is established by SolidWorks software, and the simulation curves of velocity and acceleration of the corresponding parts of the roller motor are obtained by the simulation and calculation of the physical model in MATLAB. Through the analysis of these simulation curves, we can get the factors that affect the kinematics of double rotor eccentricity shell to multi-speed motor with equal width curve. Thus, a more reasonable basis for the design of the motor is provided. The research in this paper provides a detailed basis for further optimization design, further improvement of work efficiency, reduction of production cost, expansion of application range, and provides a more detailed theoretical basis for the future finalized production of the motor.
