正交面齿轮啮合点的计算机仿真

给出了点接触面齿轮传动的齿面方程和啮合接触方程,编制了相应的计算机程序,对接触点轨迹进行了仿真;分析了主要传动参数对接触点位置的影响,获得的一些规律可供在工程应用中参考。即刀具和小齿轮齿数差、齿数比、模数对啮合接触点有很大影响:当齿数差由小变大,齿数比从大变小或当模数从大变小时,接触点向面齿轮的小端移动

Computerized Simulation of Meshing in Perpendicular Face Gear Drive

In order to avoid deflective load which may affect the strength and dynamic performances of a face gear, the face gear drives chiefly adopts spur gear whose tooth number is less than that of shaper so as to achieve point contact transmission. This paper has given the gear surface equation and meshing contact point equation in face gear drive. A program is developed to simulate the contact point track. The influence of main transmission factors on contact point position is analysed and some rules used in engineering are obtained. The gear tooth difference,tooth number ratio and modulus have great effects on the engaged contact point. If the tooth difference has been increased or tooth number ratio or modulus decreased, the contact point will move toward the small end of the face gear.
