【摘要】：齒輪傳動是現(xiàn)在機(jī)械傳動的最重要的傳動形式之一,形式很多,應(yīng)用廣泛。圓柱齒輪的分度圓形狀是半徑為常數(shù)的圓周曲線,傳動比是常數(shù),而非圓齒輪節(jié)曲線的半徑是不斷變化的,其傳動嚙合比圓齒輪要復(fù)雜很多,傳動比為變量函數(shù),并且函數(shù)的變化規(guī)律與相互嚙合的齒輪的節(jié)曲線的半徑有關(guān)。本文主要探究高階非圓類橢圓齒輪的基本傳動原理、傳動特性分析、運動學(xué)分析、動力學(xué)分析以及運動時的從動輪運動特性分析。根據(jù)齒輪嚙合原理,研究了高階非圓類橢圓齒輪的基本傳動原理,推導(dǎo)出高階非圓類橢圓齒輪的節(jié)曲線方程。齒輪傳動效率高并且傳動平穩(wěn),凸輪可以實現(xiàn)變速傳動且容易控制,然而非圓齒輪是同時兼具齒輪和凸輪二者優(yōu)點的一種集成化的機(jī)械元件,因此在實際的機(jī)械產(chǎn)品加工生產(chǎn)過程當(dāng)中,非圓齒輪相對于傳統(tǒng)的凸輪機(jī)構(gòu)和連桿變速比機(jī)構(gòu),具有壓倒性的優(yōu)勢。本文研究的非圓齒輪主要是以高階橢圓齒輪為主。本文首先介紹了國內(nèi)外非圓齒輪的研究現(xiàn)狀,根據(jù)非圓齒輪的嚙合原理,針對不同的設(shè)計參數(shù),建立了高階橢圓齒輪節(jié)曲線數(shù)學(xué)模型,接著利用MATLAB的編程計算功能編制出高階橢圓齒輪基本參數(shù)求解程序,并對其根切、凹凸性進(jìn)行校驗;根據(jù)MATLAB生成的齒廓,導(dǎo)入到SolidWorks中拉伸成三維模型,接著利用ANSYS,對高階非圓類橢圓齒輪輪齒進(jìn)行模態(tài)分析,分析階數(shù)變化時齒輪各階頻率的變化規(guī)律。最后利用ADAMS虛擬樣機(jī)仿真非圓齒輪的嚙合運動,分析階數(shù)的改變對高階非圓類橢圓齒輪的各種運動學(xué)參數(shù),動力學(xué)參數(shù)的影響,找出高階非圓類橢圓齒輪的階數(shù)變化時其各種運動學(xué)參數(shù)及動力學(xué)參數(shù)的變化規(guī)律,最后與理論曲線進(jìn)行比較。
[Abstract]:Gear transmission is one of the most important transmission forms of mechanical transmission. The indexing circle of a cylindrical gear is a circular curve with a constant radius, the transmission ratio is a constant, and the radius of the non-circular gear pitch curve is constantly changing. Its transmission meshing is much more complicated than the circular gear, and the transmission ratio is a variable function. And the variation of the function is related to the radius of the pitch curve of the meshing gear. This paper mainly discusses the basic transmission principle, transmission characteristic analysis, kinematics analysis, dynamic analysis and kinematic analysis of high order non-circular elliptic gear. Based on the meshing principle of gears, the basic transmission principle of high-order non-circular elliptical gears is studied, and the nodal curve equation of high-order non-circular elliptic gears is derived. The gear transmission efficiency is high and the transmission is stable, the cam can realize the variable speed transmission and is easy to control. However, the non-circular gear is an integrated mechanical element with both the advantages of the gear and the cam. Therefore, the non-circular gear has an overwhelming advantage over the traditional cam mechanism and linkage speed ratio mechanism in the actual machining and production process of mechanical products. The non-circular gears studied in this paper are mainly high-order elliptical gears. This paper first introduces the research status of non-circular gears at home and abroad. According to the meshing principle of non-circular gears, a mathematical model of high-order elliptic gear pitch curve is established for different design parameters. Then the program of solving the basic parameters of high-order elliptic gear is compiled by using the programming and calculating function of MATLAB, and the root cutting and convexity of the gear are checked, and the tooth profile generated by MATLAB is imported into SolidWorks to form a three-dimensional model. Then the modal analysis of the higher order non-circular elliptical gear teeth is carried out by using ANSYS.The variation law of each order frequency of the gear is analyzed when the order is changed. Finally, the meshing motion of non-circular gear is simulated by Adams virtual prototype, and the influence of the change of order on the kinematic and dynamic parameters of high-order non-circular elliptical gear is analyzed. The variation laws of various kinematics and dynamics parameters of higher order non-circular elliptic gears are found out and compared with the theoretical curves.
