滾齿机是制造齿轮的专用机床,提高滾齿机精度的意义在于:滾齿机的生产率是切齿机床中最高的。而且,可望应用高速滚齿得到成倍地提高。为了降低齿轮制造成本和减少对国外高精度机床进口,研制高精度、低成本的滾齿机具有重要的经济价值。 经过几年的理论研究和实践之后,本文提出了一种即不提高另件制造精度,又不太多的增加另件数目,而能够把普通级的滾齿机精度提高到高于目前国内精密级滾齿水平的方法。这种方法是将控制论引入机床设计中,对占整机精度65％的工作台系统进行了深入的理论分析,给出了新的设计方法。按照新的设计方法,研制成功了工作台蜗轮付的反馈控制系统。经过切齿试验和测试鉴定证明,这种系统是成功的。这种方法不但能应用于机床系统中,也可用于其他机械系统的设计中。
Gear hobbing machine is a special machine tool for manufacturing gears. The significance of improving hobbing machine precision is that the hobbing machine productivity is the highest among gear cutting machine tools. Moreover, the application of high-speed hobbing is expected to be exponentially improved. In order to reduce gear manufacturing costs and reduce the import of high-precision machine tools abroad, the development of high-precision, low-cost hobbing machine has important economic value. After several years of theoretical research and practice, this paper presents an increase that can not increase the precision of the other parts, but not too much to increase the number of parts, and can be an ordinary hobbing machine precision to higher than the current domestic precision Level hobbing level of the method. This method is to introduce cybernetics into the machine tool design, and the in-depth theoretical analysis of the workbench system which accounts for 65% of the whole machine accuracy is given, and a new design method is given. In accordance with the new design method, the successful development of the worktable worm feedback control system. After cutting teeth test and test identification proved that this system is successful. This method can not only be used in machine tool systems, but also in the design of other mechanical systems.
