【摘要】：偏置面齒輪傳動(dòng)是一種相錯(cuò)軸齒輪傳動(dòng)，這種傳動(dòng)形式能大幅度拓寬面齒輪傳動(dòng)的應(yīng)用領(lǐng)域，為設(shè)計(jì)者提供了更大的發(fā)揮空間，小齒輪軸線的偏置有利于采用跨式支承，提高傳動(dòng)系統(tǒng)的剛性，且這種傳動(dòng)類型具有較大的重合度。因此，偏置面齒輪傳動(dòng)在機(jī)械工程領(lǐng)域具有較大的發(fā)展?jié)摿Α?本文研究了偏置面齒輪傳動(dòng)的幾何原理，建立了漸開(kāi)線插齒刀加工偏置面齒輪的數(shù)學(xué)模型，推導(dǎo)了偏置面齒輪的齒面方程。根據(jù)偏置面齒輪的展成原理，推導(dǎo)了偏置面齒輪根切和頂尖的極限條件，確定了不發(fā)生根切和不發(fā)生頂尖的最小內(nèi)半徑和最大外半徑。分析了偏置面齒輪的有效齒寬與偏置距的關(guān)系。研究了變位偏置面齒輪的齒寬與變位系數(shù)的關(guān)系。 在Pro/E環(huán)境中調(diào)用齒輪庫(kù)，，對(duì)圓柱齒輪實(shí)現(xiàn)參數(shù)化建模。推導(dǎo)了偏置面齒輪的齒面網(wǎng)格點(diǎn)，根據(jù)齒面方程求出齒面點(diǎn)坐標(biāo)，導(dǎo)入Pro/E中完成了對(duì)偏置面齒輪的三維建模。 以AutCAD2006版本為開(kāi)發(fā)平臺(tái)，利用二次開(kāi)發(fā)工具ActiveX Automation，以Visual Basic為編程語(yǔ)言，實(shí)現(xiàn)了面齒輪的零件圖的繪制，建立了公差數(shù)據(jù)庫(kù)，實(shí)現(xiàn)了公差標(biāo)注的自動(dòng)化。 利用ANSYS分析軟件對(duì)圓柱齒輪和偏置面齒輪進(jìn)行了靜態(tài)的彎曲應(yīng)力分析。結(jié)果顯示：在集中載荷下，圓柱齒輪承受的最大彎曲應(yīng)力在齒根處，當(dāng)集中載荷向兩端移動(dòng)時(shí)，圓柱齒輪承受的彎曲應(yīng)力逐漸增大；偏置面齒輪承受的彎曲應(yīng)力的位置在齒面中部，當(dāng)載荷逐漸向兩端移動(dòng)時(shí)，偏置面齒輪承受的彎曲的彎曲應(yīng)力逐漸增大。 最后，根據(jù)偏置面齒輪與圓柱齒輪的嚙合原理，通過(guò)對(duì)現(xiàn)有的514型插齒機(jī)的改造，完成了偏置面齒輪的插齒加工。并對(duì)加工出來(lái)的偏置面齒輪進(jìn)行了滾檢和噪聲測(cè)試。實(shí)驗(yàn)基本上達(dá)到了預(yù)期的目的，驗(yàn)證了本文的理論研究成果。
[Abstract]:Offset face gear transmission is a kind of misalignment gear transmission. This transmission form can greatly widen the application field of face gear transmission, and provide more space for designers. The bias of pinion axis is favorable to adopt span support. Improve the rigidity of the transmission system, and this type of transmission has a greater degree of coincidence. Therefore, the offset face gear transmission has great development potential in the field of mechanical engineering. In this paper, the geometric principle of offset face gear transmission is studied, the mathematical model of involute gear shaper is established, and the tooth surface equation of offset face gear is deduced. According to the generating principle of offset face gear, the limit conditions of root cutting and center of offset face gear are derived, and the minimum inner radius and maximum outer radius of the gear with no root tangent and no center are determined. The relationship between the effective tooth width and the offset distance of the offset face gear is analyzed. The relationship between tooth width and displacement coefficient of offset face gear is studied. The parametric modeling of cylindrical gear is realized by calling gear library in Pro/E environment. The tooth surface mesh points of the offset face gear are derived, and the coordinates of the tooth surface point are obtained according to the tooth surface equation, and the 3D modeling of the offset face gear is completed by Pro/E. Taking the AutCAD2006 version as the development platform and using the secondary development tool ActiveX Automation, as the programming language, this paper realizes the drawing of the part drawing of the surface gear, establishes the tolerance database and realizes the automation of the tolerance marking. The static bending stress analysis of cylindrical gear and offset gear was carried out by using ANSYS software. The results show that the maximum bending stress of the cylindrical gear is at the root of the tooth under concentrated load. When the concentrated load moves to both ends, the bending stress of the cylindrical gear increases gradually. The bending stress of the offset face gear is located in the middle of the tooth surface. When the load moves to both ends gradually, the bending stress of the offset face gear increases gradually. Finally, according to the meshing principle of offset face gear and cylindrical gear, the gear shafting process of offset face gear is completed by modifying the existing 514 gear shaper. The rolling inspection and noise test of the gear with offset face are carried out. The experiment basically achieves the expected purpose, and verifies the theoretical research results of this paper.
