摘要 论述了面齿轮传动的研究现状及需要进一步研究的问题。作者对面齿轮传动中受到刀具数量多和齿宽窄的限制提出了新认识,认为机械产品的型号是有限的,相应所用齿轮参数也是有限的;同时通过使用现代设计方法可以充分地利用有效齿宽,需要采用现代分析技术对面齿轮的强度作进一步的深入研究。由于接触斑点的位置不仅与几何尺寸有关,还与变形及各种误差有关,这些误差又都是随机的。因此,作者在文中提出了概率弹性啮合分析的新概念。 The research state and problems to be further researched on the face gear drive are discussed. It has been reported by other authors that with proper design face gear drive can find a successful application in high power, such as helicopter transmissions. First, this paper presents a new recognition of limiting the large number of shapers and the small tooth width in the application of the face gear drive. For some kind of mechanical product, the model is limited, so are the parameters of gear. By the use of modern design method, the effective tooth width of the face gear can be fully utilized. Secondly, the strength of bend, Hertzian stress and scuffing of face gear needs to be researched further. The analysis of stresses in face gear can be made by the finite element method and boundary element method. Thirdly, the new idea of the analysis of random elastic engagement is presented. The point contact face gear drive is used in order to avoid the undesirable bearing form. The contact position of bearing is not only related to the geometry size,but also related to elastic deformation, while errors of assembly and manufacturing are random. The development of the theory of random elastic engagement is necessary.
