Mechanical Science and Technology Yang Lianshun Analysis of Bending Stress of Orthogonal Face Gears Yang Lianshun, Zhu Rupeng, Zeng Ying (Nanjing University of Aeronautics and Astronautics, Nanjing 210016) Fund Project: Finite Element Analysis of Funded Projects of National Natural Science Foundation of China (19675005) and Aviation Science Foundation (97C2023) Model, the maximum bending stress characteristics of the three-tooth model of the orthogonal face gear under different parameters (such as modulus, number of teeth, tooth width) are studied. This paper considers the most unfavorable condition of the face gear loading, that is, the tooth tip of the face gear The concentrated load is added at different positions in the width direction. The finite element analysis shows that the maximum bending stress of the face gear is not at the root but at the middle position along the tooth height direction, and the maximum bending stress is transmitted when the action point moves toward both ends. The position moves toward the top of the tooth. This is important for controlling the position of the contact points in the face gear drive design.
FaceGearDrive (FaceGearDrive) is a new type of gear transmission in which a spur gear meshes with a bevel gear (face gear). It has many unique advantages and geometric phenomena - the unit normal of the tooth surface is ns circle radius; Us is the tool The axial parameter of a point on the tooth surface; 0s is the angle parameter Us and 0s of the point on the involute of the tool is the parameter of the involute tooth surface, which is determined. Thus, the equation of the face gear is the ratio of æ², and there are m2, = k2/k=h/h. In equation (3), 0S is taken as the parameter at the tip circle of the tool, and 0S=(ra, /r, the face gear can be obtained. The transition surface equation of the tooth surface is: Shanghai Science and Technology Press, Sun Jincai, 1986, etc. Revised statistical energy balance equation, Chinese Academy of Aeronautics, 9th Mechanical Power Transmission Conference, C, 1998, Zeng Ying et al.
