【摘要】：针对齿轮传动中因齿轮齿面磨损,导致啮合间隙增大,影响装置传动效率的问题,提出了一种可补偿侧隙的3K型变齿厚行星齿轮传动装置。首先分析了该新型装置的啮合特性。运用单元分析法推导出各啮合效率与传动效率的关系。然后,基于啮合原理与积分中值定理,得到重合度、变位系数、啮合角和锥角等基本参数与啮合效率的关系,进而得出各啮合参数与整机传动效率的数学模型。最后,基于优化设计理论,以MATLAB为工具,在满足齿轮强度的条件下,以传动效率为设计目标,得出齿轮啮合参数的一组最优解。该研究对变齿厚齿轮传动装置的设计具有一定的指导作用。
[Abstract]:In order to solve the problem of gear gear tooth surface wear, which leads to the increase of meshing clearance, which affects the transmission efficiency of the device. This paper presents a 3K type planetary gear drive with variable tooth thickness, which can compensate for the backlash. Firstly, the meshing characteristics of the new gear are analyzed. The relationship between the meshing efficiency and the transmission efficiency is derived by using the element analysis method. Then, the relationship between the meshing efficiency and the transmission efficiency is derived. Based on the meshing principle and the integral mean value theorem, the relationship between the basic parameters such as coincidence degree, modification coefficient, meshing angle and cone angle and the meshing efficiency is obtained, and the mathematical model of the meshing parameters and the transmission efficiency of the whole machine is obtained. Based on the theory of optimal design, using MATLAB as a tool, under the condition of satisfying the gear strength, the design goal is to take the transmission efficiency as the design goal. A set of optimal solutions of gear meshing parameters is obtained. This study has a certain guiding effect on the design of gear transmission device with variable tooth thickness.
