钢带机数控减速器及冷却横向移动机构的设计+CAD图纸
本次课题研究的是钢带机的机构,即：钢水包的进给机构、冷却机构和横向移动机构。非晶钢带的厚度可以由钢带机托盘上铁水包与下方冷却滚筒之间距离来决定，因此，必须保证本次设计的精确度。
论文中主要介绍了钢带机工作原理、钢带机各个机构的选用以及各零件的设计计算及其校核。其中减速器是设计的重点，需要选择电机、减速器结构、轴、轴承以及联轴器等。最后进行冷却滚筒以及箱体设计

Strip machine reducer and transverse moving mechanism design
Abstract：The strip machine is a kind of equipment for the production of thin amorphous strip. The ladle can be accurately moved to designated spot with transverse moving mechanism and numerical control device, then the molten steel from the ladle in the slit flow out when cooling roller speed cooling. The crystal is not aligned on the formation of amorphous strip. This material is widely used, and can save a lot of energy as while.
This research focused on the mechanism of strip machine, including feeding mechanism of ladle, cooling mechanism and transverse moving mechanism. The distance of ladle and cooling drum can directly control the thickness of amorphous strip, so accuracy is the most important factor.
This paper mainly introduced the working principle of steel band machine, how to select each part of it, design and calculation of various parts, and how to check those parts. Among them, reducer is the focus of this design, including choosing the type of motor, reducer structure determination, selecting the right bearing and coupling structure of all. Finally we could design the cooling roller and cabinet.
Key words: strip machine；CNC gear reducer；transverse moving mechanism ;high-precision
