The phenomenon of increased loading capacity caused by several contact teeth is called the multi - tooth meshing effect 我们将齿轮啮合过程中因多齿啮合而导致齿轮副承载能力提高的现象称为多齿啮合效应。
So , it is of great importance to study multi - tooth meshing effect of three - ring gear reducer to disclose the essence of high loading capacity of three - ring gear reducer , increase loading capacity , minimize design parameters and reduce manufacturing cost 因此,考虑三环传动中的多齿啮合效应对于揭示三环减速器大承载能力的本质、提高三环减速器的承载能力、缩小设计尺寸、降低制造成本具有重要的意义。
Aimed to the two deficiencies of three - ring gear transmission , the dissertation will analyze these two aspects . the first , according to the finite element model of gear pair of three - ring gear reducer , the dissertation is aimed to analyze the multi - tooth meshing effect of three - ring gear reducer using finite element method , and the number of teeth contacted simultaneously , their load distribution characteristics and the von mises stress change are gained 针对三环减速器以上两点的不足之处,本文将对以下两方面进行分析:首先,本文以三环减速器齿轮副有限元模型为研究对象,利用有限单元法对三环减速器多齿啮合效应进行分析,得到三环减速器传动时的实际接触齿数、啮合齿载荷分配以及vonmises应力变化规律。
The types of ecosystem in the region included wetland ecosystem , agricultural ecosystem ( including paddy field and dry lands ) and forest ecosystem . a large number of species of acridoidea were in frost ecosystem , about 38 species , afterwards in file dry land agricultural ecosystem ( 22 species ) , wetland ecosystem ( 11 species ) and paddy field ( 10 species ) 佛坪自然保护区特有种比较多，例如透翅凸额蝗traulishyulinalazhengetal 、佛坪刁蹦蝗sinopodismafopingensllvzhengetal和多齿稻蝗oxyamultldentalazhengetal等蝗虫发生规律方面，汉中地区8月份出现的成虫种类最多，达36种， 9 、 10月份次之，分别为30种和26种， 4月份最少，为2种。
