一、问题的提出本钢热连轧厂热连轧机组生产能力的提高,受到了传动系统减速机及齿轮座的强度限制。为适应生产要求提高轧机的生产能力,现场要求对传动系统减速机及齿轮座等进行改造。且要求投资少上马快,提出仍采用原减速机箱体、轴及轴承结构,总速比不变,提高传功齿轮的承载能力。据此,本文对连轧机组的减速机及齿轮座进行了最优化设计及分析。设计时假定在不改变原齿轮的材质及热处理,不改变加工精度,对啮合参数进行优选,以提高齿轮的承载能力。
First, the issue put forward Bengang Tandem hot rolling mill production capacity increase, by the transmission reducer and gear seat strength limit. In order to meet the production requirements to improve the mill’s production capacity, on-site requirements for transmission reducer gear box and so on. And asked to invest less quickly, put forward still using the original reducer box, shaft and bearing structure, the total speed ratio unchanged, to improve the carrying capacity of power transmission gear. Accordingly, this article has carried on the optimal design and the analysis to the speed reducer and the gear seat of the rolling stand. The design is assumed to be in the original gear without changing the material and heat treatment, does not change the machining accuracy, the meshing parameters for optimization, in order to improve the carrying capacity of the gear.
