【摘要】：本课题研制设计的三型内啮合齿轮马达是一种新型的可变量、低脉动的液压马达。本课题来源于安徽省教育厅自然基金重点项目：《新型内啮合齿轮马达关键技术研究》(KJ2011A094)。三型内啮合齿轮马达的扭矩脉动仅仅是普通内啮合齿轮马达的1/9,从而大大降低系统的噪音污染；该齿轮马达通过改变齿轮接触时的齿宽而实现了变量,大大扩展了齿轮马达的应用范围。本文首先分析了三型内啮合齿轮马达的瞬时扭矩特性,并对其进行仿真,将分析的结果与普通齿轮内啮合齿轮马达进行比较。其次建立了三型内啮合齿轮马达的仿真模型,并利用有限元分析软件对三型内啮合齿轮马达的端面泄漏和径向泄漏分别进行流场仿真分析,并得到压差为2MPa时,不同的端面间隙、径向间隙与泄漏流量的关系,接着对三型内啮合齿轮马达进行了模态分析和静力分析,最终得出齿轮马达适用的频率范围和安全系数。接着以体积和瞬时扭矩脉动最小的为目标函数,建立了三型内啮合齿轮马达的优化数学模型,并利用MATLAB的优化工具箱得出了最终的优化结果。最后设计了三型内啮合齿轮马达的变量机构,对主要的零部件进行了设计。
[Abstract]:The three type internal meshing gear motor developed by this project is a new type of variable, low pulsating hydraulic motor. This topic comes from the key project of the natural fund of the Anhui Provincial Education Department: "the key technology of the new internal meshing gear motor" (KJ2011A094).
The torque ripple of the three type inner meshing gear motor is only the 1/9 of the ordinary inner meshing gear motor, which greatly reduces the noise pollution of the system. The gear motor realizes the variable by changing the tooth width of the gear contact, and greatly expands the application range of the gear motor.
In this paper, the instantaneous torque characteristic of the three type internal meshing gear motor is analyzed, and the simulation is carried out. The results are compared with the ordinary gear internal gear motor.
Secondly, the simulation model of three type internal meshing gear motor is established, and the finite element analysis software is used to simulate the flow field of the end surface leakage and radial leakage of the three type inner meshing gear motor, and the relationship between the different end surface clearance, the radial clearance and the leakage flow is obtained when the pressure difference is 2MPa, and then the three type internal meshing gear horse is made. Modal analysis and static analysis were carried out, and the frequency range and safety factor of gear motor were finally obtained.
Then the optimization mathematical model of the three type internal meshing gear motor is established with the minimum volume and instantaneous torque ripple as the objective function, and the final optimization results are obtained by using the optimization toolbox of MATLAB.
Finally, the variable mechanism of the three type internal meshing gear motor is designed, and the main parts are designed.
