【摘要】：本文结合谐波齿轮传动的啮合理论以及样条曲线的相关知识点,提出了一种新型的谐波传动齿型--β型齿型。该齿型符合谐波传动啮合原理,可提高谐波减速器的性能,还具有调整方便的特点。同时以共轭原理为基础,完成了谐波减速器β型齿型的设计软件,并根据共轭理论,利用本软件对渐开线齿型进行了分析和验证。本文的主要内容简述如下：(1)在研究渐开线齿型的理论基础上,以样条曲线为基础,提出了β型齿型,即根据具体参数,得出柔轮的初始齿廓方程,再根据设定的优化准则,将柔轮齿廓曲线进行优化,最终得出优化齿型。(2)以共轭理论为基础,得出了与柔轮齿型相共轭的刚轮曲线,该曲线与柔轮齿型处于理论共轭状态。(3)在求出上述共轭曲线的基础上,计算出了刚轮曲线的法向移距曲线,以满足实际背隙的要求。(4)可将最终齿廓曲线用AutoCAD进行精确描述,并利用ANSYS软件对模型进行了静力分析。(5)利用ANSYS软件,在同等加载条件下,将具有β型齿型的谐波减速器柔轮与同规格双圆弧和渐开线齿型的柔轮进行了应力分布的仿真对比,结果表明：β型齿型在这一方面的性能明显高于其余两种齿型。(6)在上述工作的基础上,编制了绘制柔轮β型齿廓曲线以及共轭曲线的软件,输入相应参数后,该软件可方便地绘制所求规格的β型齿廓曲线。(7)最后,以32-80型渐开线齿型作为验证对象,进行了渐开线齿廓曲线的验证,并根据验证的结果加工出了实物样机。通过上述工作,说明β型齿型与现有齿型相比更具有先进性,更符合谐波齿轮传动的啮合要求,使得谐波减速器的性能更加完善。
[Abstract]:Based on the meshing theory of harmonic gear transmission and the related knowledge of spline curve, a new type of harmonic transmission tooth shape-尾 tooth type is proposed in this paper. The tooth shape accords with the meshing principle of harmonic drive, can improve the performance of harmonic reducer, and has the characteristic of convenient adjustment. At the same time, based on the conjugate principle, the design software of the 尾 tooth profile of harmonic reducer is completed, and according to the conjugate theory, the involute tooth profile is analyzed and verified by the software. The main contents of this paper are summarized as follows: (1) on the basis of the theory of involute tooth profile and spline curve, the 尾 tooth profile is put forward, that is, according to the specific parameters, the initial tooth profile equation of the flexible wheel is obtained, and then according to the set optimization criterion, The tooth profile curve of flexible wheel is optimized, and the optimized tooth profile is obtained. (2) based on conjugate theory, the curve of rigid wheel conjugate with the tooth shape of flexible wheel is obtained. The curve is in a theoretical conjugate state with the flexo tooth profile. (3) on the basis of the above conjugate curves, the normal distance curve of the rigid wheel curve is calculated to meet the requirements of the actual back gap. (4) the final tooth profile curve can be accurately described by AutoCAD. The static analysis of the model is carried out by using ANSYS software. (5) the stress distribution of harmonic reducer with 尾 tooth is compared with that of double arc and involute gear of the same size by using ANSYS software under the same loading condition. The results show that the performance of 尾 type tooth shape is obviously higher than that of the other two tooth types. (6) on the basis of the above work, a software is developed to draw the curve of 尾 shape tooth profile and conjugate curve of flexible wheel, and the corresponding parameters are input into the software. The software can easily draw the 尾 type tooth profile curve. (7) finally, the involute tooth profile curve of 32-80 type is used as the verification object, and the physical prototype is processed according to the verification results. Through the above work, it is shown that the beta-type tooth type is more advanced than the existing tooth type, more in line with the meshing requirements of harmonic gear transmission, and makes the performance of harmonic reducer more perfect.
