Because there are frequent failures in the connection method which uses crosshead intermediate axle shaft to join the relevant oart in the axis system of transmission system coupling this article suggests to use copper sliding pieces type transmission to increase the life of the middle axle system in transmission 摘要针对主传动中间轴系统采用十字头联轴器与相关件连接方式，故障较多，改进为铜滑块式传动，提高了主传动中间轴系统的寿命。
Specially , in recent years , it has realized the roller change quickly and the main - drive system , the two level automation reformed successfully . on this condition , it realized the technology optimization , increased the task rate of unit and production quality , expanded the rolling kind and specification , and got the significant economic effects 特别是近几年来快速换辊和主传动系统、两级自动化改造成功,并在此基础上实现了工艺优化,使轧机作业率、产品质量有了明显提高,轧制品种和规格有了扩展,经济效益显著。
By means of the method of combining theoretic analysis with mathematic calculation , the mathematic model of medium mill ' s electromechanical twist vibration was established , the whole response of the system in transition process was obtained by the solution of the model , the clearance and skid of main transmission system were analyzed in rolling process , and they were studied with computer simulation 摘要采用理论分析和数值计算相结合的方法建立了中厚板轧机机电扭振数学模型，通过对该模型的求解，得到系统在过渡过程中的全部响应，且对轧机在轧制过程中的主传动系统的间隙和打滑两种状态进行了分析，并对此进行了计算机仿真研究。
Abstract : the present article introduces the principal factors governingthe movement process of the turnover machine , describes the revamp on the original control system of the main driver and heavy truck hauling device of the turnover machine including application of quadrant logic speed regulation system and supersynchronous logic compensating state control system into the revamp of the machine as well as the function and features of the systems , and discusses the movement process of the main driver of the turnover machine 文摘:介绍翻车机的运行过程要素，对翻车机主传动及重车牵引原控制系统进行改造，引入四象限逻辑控制调速系统及超同步逻辑补偿状态控制系统，阐述其性能、特点及工作过程，针对翻车机主传动运行过程展开讨论。
The spindle is supported by high - accuracy rolling bearing ; the frequency governor imported from abroad is used in the main drive system to realize stepless speed regulation and constant linear cutting functions ; the bed is supersonic frequeney hardened , plastic coated guide ways are used for the carriage ; and stepping motor of acservo motor are used x and z axis to realize feed movement via the ball screws 主轴采用高精度的滚动轴承支承；主传动采用进口变频调速器，实现无级调速功能及恒线速切削功能；床身采用超音频淬硬处理，采用贴塑导轨； x轴和z轴均采用步进或伺服电机，通过滚珠丝杠，实现进给运动。
