【摘要】：面齒輪傳動(dòng)具有很多獨(dú)特的優(yōu)點(diǎn),尤其是在高速重載的場合。本文主要對(duì)非正交面齒輪傳動(dòng)的嚙合特性與強(qiáng)度進(jìn)行分析。 在本文中,推導(dǎo)出非正交面齒輪的齒面方程,并且推導(dǎo)出兩種刀具所生成的非正交面齒輪齒根過渡曲面方程。根據(jù)生成齒面方程,編制MATLAB程序?qū)Ψ钦幻纨X輪齒廓進(jìn)行仿真。 為了分析安裝誤差對(duì)非正交面齒輪傳動(dòng)接觸軌跡的影響,建立考慮軸交角、軸交錯(cuò)、軸向偏移三個(gè)安裝誤差的非正交面齒輪傳動(dòng)坐標(biāo)系。推導(dǎo)相應(yīng)的接觸軌跡方程,分析不同安裝誤差對(duì)傳動(dòng)中非正交面齒輪接觸軌跡的影響。通過得到的接觸軌跡,對(duì)非正交面齒輪的接觸點(diǎn)曲率進(jìn)行計(jì)算,得出接觸點(diǎn)處的主方向。由于齒面彈性,接觸形式由點(diǎn)接觸擴(kuò)展成橢圓。本論文中求出擴(kuò)展成的接觸橢圓半徑。同時(shí)對(duì)非正交面齒輪傳動(dòng)中齒面的相對(duì)速度進(jìn)行計(jì)算,基于H.Block理論,建立了非正交面齒輪傳動(dòng)的齒面瞬時(shí)接觸溫度的計(jì)算公式。 最后,用CATIA對(duì)非正交面齒輪進(jìn)行建模,主要介紹幾種非正交面齒輪的建模方法,利用VB.NET對(duì)CATIA進(jìn)行二次開發(fā),得出非正交面齒輪的齒面,得出非正交面齒輪的模型。然后利用ANSYS對(duì)不同參數(shù)影響下,對(duì)非正交面齒輪齒根彎曲應(yīng)力進(jìn)行計(jì)算,并分析這些參數(shù)對(duì)彎曲應(yīng)力的影響。
[Abstract]:Surface gear transmission has many unique advantages, especially in the case of high speed and heavy load. In this paper, the meshing characteristics and strength of non-orthogonal face gear transmission are analyzed. In this paper, the tooth surface equation of non-orthogonal surface gear is derived, and the equation of tooth root transition surface of non-orthogonal face gear produced by two kinds of cutters is derived. A MATLAB program is developed to simulate the tooth profile of non-orthogonal surface gear. In order to analyze the influence of the installation error on the contact track of the non-orthogonal face gear transmission, the axial intersection angle is considered and the shaft is staggered. The non-orthogonal surface gear transmission coordinate system with three installation errors is deviated. The corresponding contact trajectory equation is derived. The influence of different installation errors on the contact trajectory of non-orthogonal gear is analyzed. The contact point curvature of non-orthogonal gear is calculated through the contact trajectory obtained. Get the main direction of the contact point. Due to tooth surface elasticity. The contact form is extended from point contact to ellipse. In this paper, the radius of contact ellipse is obtained. At the same time, the relative velocity of tooth surface in non-orthogonal gear transmission is calculated based on H.Block theory. The formula for calculating the instantaneous contact temperature of tooth surface of non-orthogonal face gear transmission is established. Finally, CATIA is used to model the non-orthogonal face gear. Several modeling methods of non-orthogonal face gear are introduced, and the secondary development of CATIA is carried out by using VB.NET. The tooth surface of the non-orthogonal face gear and the model of the non-orthogonal face gear are obtained. Then the bending stress of the tooth root of the non-orthogonal face gear is calculated by using ANSYS under the influence of different parameters. The effect of these parameters on bending stress is analyzed.
