【摘要】：面齒輪傳動具有很多獨特的優(yōu)點,尤其是在高速重載的場合。本文主要對非正交面齒輪傳動的嚙合特性與強度進行分析。 在本文中,推導出非正交面齒輪的齒面方程,并且推導出兩種刀具所生成的非正交面齒輪齒根過渡曲面方程。根據生成齒面方程,編制MATLAB程序對非正交面齒輪齒廓進行仿真。 為了分析安裝誤差對非正交面齒輪傳動接觸軌跡的影響,建立考慮軸交角、軸交錯、軸向偏移三個安裝誤差的非正交面齒輪傳動坐標系。推導相應的接觸軌跡方程,分析不同安裝誤差對傳動中非正交面齒輪接觸軌跡的影響。通過得到的接觸軌跡,對非正交面齒輪的接觸點曲率進行計算,得出接觸點處的主方向。由于齒面彈性,接觸形式由點接觸擴展成橢圓。本論文中求出擴展成的接觸橢圓半徑。同時對非正交面齒輪傳動中齒面的相對速度進行計算,基于H.Block理論,建立了非正交面齒輪傳動的齒面瞬時接觸溫度的計算公式。 最后,用CATIA對非正交面齒輪進行建模,主要介紹幾種非正交面齒輪的建模方法,利用VB.NET對CATIA進行二次開發(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對不同參數(shù)影響下,對非正交面齒輪齒根彎曲應力進行計算,并分析這些參數(shù)對彎曲應力的影響。
[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.
