【摘要】：面齒輪傳動(dòng)是圓柱齒輪與面齒輪相嚙合，，實(shí)現(xiàn)類似圓錐齒輪空間相交或交錯(cuò)傳動(dòng)的新型齒輪傳動(dòng)。由于國內(nèi)對(duì)面齒輪傳動(dòng)的研究起步較晚，對(duì)面齒輪彎曲應(yīng)力計(jì)算方法研究還處于集中載荷加載方式的理論研究階段，尚未開展相關(guān)的驗(yàn)證試驗(yàn)。為了進(jìn)一步研究面齒輪彎曲應(yīng)力計(jì)算方法，并對(duì)彎曲應(yīng)力計(jì)算方法進(jìn)行試驗(yàn)驗(yàn)證，本文就面齒輪傳動(dòng)的彎曲應(yīng)力計(jì)算方法及其試驗(yàn)進(jìn)行研究，為面齒輪的工程應(yīng)用打下基礎(chǔ)。 首先，運(yùn)用有限元法對(duì)正交面齒輪傳動(dòng)的彎曲應(yīng)力進(jìn)行研究。在對(duì)正交面齒輪傳動(dòng)的彎曲應(yīng)力進(jìn)行分析和計(jì)算公式擬合時(shí)，先根據(jù)正交試驗(yàn)法的原理，運(yùn)用正交表確定有限元法分析模型的因素和水平，分集中載荷加載和均布載荷加載2種加載方式，對(duì)正交面齒輪傳動(dòng)的彎曲應(yīng)力進(jìn)行有限元分析，獲得正交面齒輪傳動(dòng)在2種載荷加載方式下的彎曲應(yīng)力分布規(guī)律；再運(yùn)用最小二乘法對(duì)有限元分析結(jié)果進(jìn)行擬合，得出正交面齒輪傳動(dòng)在2種加載方式下的彎曲應(yīng)力計(jì)算公式；最后對(duì)2種載荷加載方式下的擬合計(jì)算公式值與有限元法分析值的相對(duì)誤差進(jìn)行分析研究，驗(yàn)證2種載荷加載方式下正交面齒輪傳動(dòng)的彎曲應(yīng)力擬合計(jì)算公式的合理性。 其次，運(yùn)用試驗(yàn)法對(duì)正交面齒輪傳動(dòng)的彎曲應(yīng)力進(jìn)行研究。先根據(jù)正交面齒輪傳動(dòng)的嚙合關(guān)系，設(shè)計(jì)出適合正交面齒輪傳動(dòng)的彎曲應(yīng)力試驗(yàn)用夾具；再對(duì)與有限元分析模型參數(shù)相同的正交面齒輪的彎曲應(yīng)力進(jìn)行測(cè)量試驗(yàn)；最后分析試驗(yàn)測(cè)試值與2種載荷加載方式下的擬合計(jì)算公式計(jì)算值的相對(duì)誤差。根據(jù)本文相對(duì)誤差分析結(jié)果，提出擬合計(jì)算公式的修正系數(shù)為0.92，為正交面齒輪強(qiáng)度校核和深入研究奠定基礎(chǔ)。 最后，根據(jù)本文對(duì)正交面齒輪傳動(dòng)的彎曲應(yīng)力計(jì)算方法及試驗(yàn)研究結(jié)果，編寫了正交面齒輪傳動(dòng)的彎曲應(yīng)力計(jì)算程序，開發(fā)了計(jì)算軟件模塊。此軟件模塊通過輸入正交面齒輪傳動(dòng)的基本參數(shù)和工況條件，可以計(jì)算出正交面齒輪傳動(dòng)的彎曲應(yīng)力和安全系數(shù)，實(shí)現(xiàn)正交面齒輪傳動(dòng)的彎曲應(yīng)力計(jì)算和強(qiáng)度校核參數(shù)化。
[Abstract]:Face gear drive is cylindrical gear and gear meshing, gear transmission model to achieve a similar space intersection or bevel gear transmission. Because of the staggered domestic face gear starts late, the stress calculation method research is still in the stage of theoretical research on load - bending face gear, has not yet been carried out tests related to. Bending stress calculation method for further research on face gear, and calculation method of the bending stress test, the face gear bending stress calculation method and test research, lay the foundation for the engineering application of the face gear.
First of all, using the finite element method for bending of orthogonal face gear stress were studied. The bending stress of gear transmission orthogonal analysis and calculation formula, according to the principle of the orthogonal test, using orthogonal table to determine the finite element method to analyze the factors and levels of the model, loading and concentration cloth loading 2 kinds of loading mode, the bending of orthogonal face gear stress finite element analysis, bending of orthogonal face gear drive in 2 loading mode in the distribution of stress; and then use the least squares method to fit the results of finite element analysis, the orthogonal face gear drive in 2 kinds of bending load the stress calculation formula; finally the fitting 2 loading mode calculation formula and finite element method analysis of relative error value analysis, verify the 2 loading modes are The reasonableness of the bending stress fitting formula of the surface gear drive.
Secondly, using the method of bending test of orthogonal face gear stress is studied. According to the orthogonal face gear drive meshing relationship, design a suitable bending of orthogonal face gear transmission should clamp force test; then the measurement test on the bending stress and the finite element analysis model of the orthogonal face gear parameters of the same relative; finally, the error formula for calculating the value analysis and fitting the test value and 2 kinds of loading modes. According to the relative error of the results of the analysis, put forward the correction coefficient of fitting formula is 0.92, and laid the foundation for the orthogonal face gear strength analysis and in-depth study.
Finally, according to the orthogonal face gear bending stress calculation method and test results, preparation of orthogonal face gear drive bending stress calculation program, calculation software is developed. This software module module through the basic parameters and working conditions of the input of the orthogonal face gear drive, can calculate the bending of orthogonal face gear drive the stress and safety factor, realize the bending of orthogonal face gear transmission stress calculation and strength check parameters.
