【摘要】：本文首先根據(jù)交錯(cuò)軸斜齒輪傳動(dòng)的空間嚙合原理，在合適的坐標(biāo)系中，，建立了交錯(cuò)軸斜齒輪傳動(dòng)齒面接觸分析的幾何模型，為后面在MATLAB中繪制瞬時(shí)接觸橢圓，進(jìn)行齒面接觸分析提供了理論基礎(chǔ)。 其次，利用MATLAB軟件編程，建立交錯(cuò)軸斜齒輪傳動(dòng)齒面接觸模型，并繪制出兩齒面接觸時(shí)的瞬時(shí)接觸橢圓；通過(guò)對(duì)不同參數(shù)的交錯(cuò)軸斜齒輪傳動(dòng)進(jìn)行研究，分析出不同參數(shù)對(duì)齒面接觸區(qū)的影響規(guī)律；得到在不同的條件下，通過(guò)合理選擇基本參數(shù)來(lái)提高齒輪的接觸性能。 最后，在PRO/E中建立交錯(cuò)軸斜齒輪傳動(dòng)三維運(yùn)動(dòng)仿真模型，導(dǎo)入到ANSYS中進(jìn)行齒面接觸應(yīng)力分析；運(yùn)用ANSYS的結(jié)構(gòu)靜力學(xué)模塊，得到了齒面接觸區(qū)的形狀和應(yīng)力應(yīng)變?cè)茍D，分析出交錯(cuò)軸斜齒輪傳動(dòng)齒面接觸應(yīng)力和應(yīng)變分布情況，直觀的顯示了齒輪在嚙合時(shí)的接觸變形和應(yīng)力分布情況，為如何提高齒輪的嚙合性能提供了理論依據(jù)，為后續(xù)進(jìn)一步尋找可行的失配嚙合修形方法和加工工藝奠定了基礎(chǔ)。
[Abstract]:In this paper, according to the spatial meshing principle of staggered helical gear transmission, a geometric model of tooth surface contact analysis of staggered helical gear transmission is established in a suitable coordinate system, which is used to draw instantaneous contact ellipse in MATLAB. The theoretical basis for tooth surface contact analysis is provided. Secondly, by using MATLAB software, the tooth surface contact model of staggered helical gear transmission is established, and the instantaneous contact ellipse is drawn when two tooth surfaces are in contact, and the different parameters of staggered helical gear transmission are studied. The influence of different parameters on the contact region of tooth surface is analyzed, and the contact performance of gear is improved by reasonable selection of basic parameters under different conditions. Finally, a three-dimensional kinematic simulation model of staggered helical gear transmission is established in PRO/E, which is introduced into ANSYS for tooth surface contact stress analysis, and the shape and stress-strain cloud diagram of tooth surface contact area are obtained by using the structural statics module of ANSYS. The distribution of contact stress and strain on gear surface of staggered helical gear transmission is analyzed. The contact deformation and stress distribution of gear in meshing are shown intuitively, which provides a theoretical basis for how to improve the meshing performance of gear. It lays a foundation for further searching for feasible mismatch meshing modification method and processing technology.
