A meshing simulation of a face-gear and a cylindrical gear, with difference in the number of teeth Δ =1−3, was conducted to obtain the contact path of face-gear tooth surface and the area and shape of contact region, with corresponding programs programmed by using MATLAB software. And the conclusion was right verified by the detection experiments on face-gear tooth surface contact. The results show that the difference in numbers of teeth of the cylindrical gear has little effect on the area and location of the contact area of the tooth surface in face-gear transmission, while the transmission ratio has a great impact on the location of the contact area of tooth surface. The larger the transmission ratio, and closer of the tooth contact area to the middle of the face gear teeth, the more improvement for the property of face-gear transmission. The area and shape of the tooth surface contact area is influenced by the manufacturing precision. The higher accuracy and more stabe, the area and shape of the tooth surface contact area bring about the higher quality of transmission. Therefore, large transmission ratio and high manufacture precision are beneficial to improve the quality of face-gear transmission. Key words: face-gear meshing; contact path; contact area of tooth surface; transmission ratio
摘要：根据面齿轮啮合原理，研究面齿轮啮合过程中的齿面接触特性；运用 MATLAB 软件编制相应的程序仿真 接触区域面积及形状， 并通过面齿轮齿面接 出齿数差 Δ =1~3 的圆柱齿轮与面齿轮啮合时面齿轮齿面的接触轨迹、 触检测实验验证其正确性。研究结果表明：圆柱齿轮的齿数差对面齿轮传动的齿面接触区域的面积和位置影响不 大，而传动比对齿面接触区域的位置影响较大，传动比越大，齿面接触区域越靠近面齿轮轮齿的中部，越有利于 提高面齿轮传动的性能。同时实验表明齿面接触面积和形状受制造精度影响，精度越高，齿面接触区域面积和形 状越稳定，传动质量越高。因此，大的传动比和高的制造精度对提高面齿轮的传动性能是有益的。 关键词：面齿轮啮合；接触轨迹；齿面接触区域；传动比 中图分类号：TH132.4 文献标志码：A 文章编号：1672−7207(2013)01−0095−06
