【摘要】：目前,随着现代工业技术的迅速发展,液压传动与控制技术也在不断随之高速发展,因此对现有使用中的液压马达的性能参数提出了更高要求。传统的液压马达在结构上都是一个转子对应一个定子,只能实现一种转速转矩的输出,而本论文研究的是一种特殊结构类型的新型轴向液压马达,此种液压马达结构上的最大特点是由一个转子对应两个定子,而且不需要回程弹簧。能够在马达单位重量保持不变的情况下获得比传统马达更大的比功率。由于该马达的特殊结构实现了在一个马达壳体内多个马达同时工作,所以可以实现多种不同转速和转矩的等倍输出,扩展了液压马达的应用范围和性能参数。本文首先对目前常用的几种液压马达进行了简要的分析和论述,然后介绍了本文要研究的新型液压马达的结构特点及工作原理,并使用三维建模软件SolidWorks对其进行计算机实体建模,以便更好的理解该马达的结构和原理。通过对该马达的主要运动部件进行运动学和动力学分析,并利用SolidWorks的仿真插件CosmosMotion和CosmosWorks对马达的主要部件的运动和受力进行计算机仿真分析,得出了其主要运动部件的运动规律曲线图和受力形变状态图,找到了在设计中应该注意加强的应力集中点。文中对该马达在多种情况下的转速输出进行了详细的分析,得出了马达输出转速表达式和马达输出转速不均匀系数的表达式,最终推导出其输出转速与其各个结构参数之间的相互关系,并得出相应的计算公式。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]:At present, with the rapid development of modern industrial technology, hydraulic transmission and control technology is also developing rapidly. Therefore, the performance parameters of the existing hydraulic motors are put forward higher requirements.
The structure of traditional hydraulic motor is a rotor corresponds to a stator, can only achieve a speed of output torque, and this paper is a new type of axial hydraulic motor is a special type of structure, the biggest characteristic of this kind of hydraulic motor structure consists of a rotor of two stator, and not need to return spring. Can remain unchanged for more than traditional motor power. The motor unit weight due to the special structure of the motor can work at the same time in a motor shell of a plurality of motors, so you can achieve a variety of other times is not the same output speed and torque, and expanded the range of application of hydraulic motor the performance and parameters.
This paper first analyzes and discusses briefly on several commonly used hydraulic motor, then introduces the structure and working principle of new type hydraulic motor is studied in this paper, and the computer modeling using 3D modeling software SolidWorks, in order to better understand the motor structure and principle of kinematics and dynamics analysis by. The main moving parts of the motor, and the use of SolidWorks simulationsoftware CosmosMotion and CosmosWorks are main parts of the motor movement and force analysis of the computer simulation, the motion curve of the main moving parts of the deformation and stress state diagram, found in the design should pay attention to strengthening the stress concentration. In this paper, the output speed in various conditions of the motor are analyzed in detail, the expression of the motor output speed and motor transport In the end, the relation between the output speed and the parameters of each structure is deduced, and the corresponding formula is obtained.
This research provides a detailed basis for future optimization design, further improving work efficiency, reducing production cost and expanding application scope, and provides a detailed theoretical basis for the future production of the motor.
