毕业论文2150F2精轧机主传动系统设计说明

2150F2精轧机主传动系统设计摘 要 本次毕业设计的设计对象是 2150F2精轧机主传动系统。轧钢机主传动系统主要由电动机、减速器、齿轮座、连接轴以与联轴节等组成。对于 2150 精轧机来说，其轧制要求有较高的精度，板型要有较高的平整度，就要对轧机的各个部件进行精准的设计。该论文主要以轧机的主传动为主题展开，对轧机主传动的设计就要求对于涉与到传动件的各个部件如电动机、减速器、齿轮座、连接轴、联轴器等进行设计计算，需要对轧机的轧制力、传动力矩和传动功率进行计算，对主电机容量进行选择，对设计好的主减速机的齿轮、轴以与联接轴进行强度校核，直到满足要求。本文通过几次反复的计算已满足要求。设计好轧机的尺寸结构以后需要对润滑方式的进行选择，并对轧机的经济性、环保性进行评估。当各个方面都满足时才是一个合格的设计。关键词：主传动；设计；校核；减速机;润滑；环保The Design Of The Main Driver Of 2150F2 Finishing millABSTRACTThe design of this graduation project is the main drive structure of 2150F2 finishing mill. The main drive system of a rolling mill is mainly composed of an electric motor,a reduced, a gear seat,a connecting shaft and a coupling. For the 2150 finishing mill,its rolling requirements have higher precision,the flatness of the plate must be higher, so it is necessary to carry out precise design of each part of the rolling mill. This paper mainly to themaindrive for the theme, design of the main drive requires eachcomponent to involvetransmission parts such as motor, reducer, gear seat and a connecting shaft, coupling design and calculation, calculation of rolling force of rolling mill,the required driving torque andthetransmissionpower, the selection of the main the capacity of motor, reducer design ofthe gear shaft and the connecting shaft and check the strength ,until the meet therequirements. After designing the size structure of rolling mill, it is necessary to select the lubrication mode, and evaluate the econo...
