发布时间：2018-11-17 07:25
【摘要】：偏置面齿轮传动是一种相错轴齿轮传动，这种传动形式能大幅度拓宽面齿轮传动的应用领域，为设计者提供了更大的发挥空间，小齿轮轴线的偏置有利于采用跨式支承，提高传动系统的刚性，且这种传动类型具有较大的重合度。因此，偏置面齿轮传动在机械工程领域具有较大的发展潜力。 本文研究了偏置面齿轮传动的几何原理，建立了渐开线插齿刀加工偏置面齿轮的数学模型，推导了偏置面齿轮的齿面方程。根据偏置面齿轮的展成原理，推导了偏置面齿轮根切和顶尖的极限条件，确定了不发生根切和不发生顶尖的最小内半径和最大外半径。分析了偏置面齿轮的有效齿宽与偏置距的关系。研究了变位偏置面齿轮的齿宽与变位系数的关系。 在Pro/E环境中调用齿轮库，，对圆柱齿轮实现参数化建模。推导了偏置面齿轮的齿面网格点，根据齿面方程求出齿面点坐标，导入Pro/E中完成了对偏置面齿轮的三维建模。 以AutCAD2006版本为开发平台，利用二次开发工具ActiveX Automation，以Visual Basic为编程语言，实现了面齿轮的零件图的绘制，建立了公差数据库，实现了公差标注的自动化。 利用ANSYS分析软件对圆柱齿轮和偏置面齿轮进行了静态的弯曲应力分析。结果显示：在集中载荷下，圆柱齿轮承受的最大弯曲应力在齿根处，当集中载荷向两端移动时，圆柱齿轮承受的弯曲应力逐渐增大；偏置面齿轮承受的弯曲应力的位置在齿面中部，当载荷逐渐向两端移动时，偏置面齿轮承受的弯曲的弯曲应力逐渐增大。 最后，根据偏置面齿轮与圆柱齿轮的啮合原理，通过对现有的514型插齿机的改造，完成了偏置面齿轮的插齿加工。并对加工出来的偏置面齿轮进行了滚检和噪声测试。实验基本上达到了预期的目的，验证了本文的理论研究成果。
[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.
