1、设计说明书 第 页DF-300 多层纸复合机组裁切部分设计摘 要这次设计的目的是设计出一套能够生产高质量防渗漏纸垫的机械设备.这次设计包括各种传动装置的选择与设计计算,还有气缸的计算选择,电动机,减速器的选择.首先是功率的分配.牵引所需要的功率是由主电机分配而来,切纸所需要的功率由一个调速电机经过减速装置后直接提供.传动方面包括链轮的设计,根据所需要的功率以及转速选择合适的链轮型号以及合适的中心距.在各个传动装置之间合理地分配传动比,既要求严格地完成各种功能要求,包括精度等技术要求,还要在此基础上尽量地减少设计制造的成本.使用气缸控制线压力,可以保持压力的准确,也减少了工人的劳动强度.节省了人
2、力资源,减速器的选用使传动结构大为简化,使设计的机械更轻便.关 键 词 ： 比 较 ， 传 动 ， 气 缸 ， 结 构 设计说明书 第 I 页DF-300 Multilayer Laminating Paper Cutting Part Cutting Part Of The DesignAuthor:Zhang XudongTutor:Zou JingchaoAbstractThe aim of the design is to design a machine that can produce high quality paper mat that can defend percolati
3、on. The design contains the comparison of the moving device, and the design calculation of the air cylinder, and the choice of the electric motor, decelerating machine.First,the allotment of the power. The power which lead the paper to move is branches from the main electric motor, at the same time,
4、 the power what the cutting part need is from a motor which can change its speed. The moving device contains the design of the chain, according to the power needed and the speed to choose the suitable chains. To allotment the suitable number between different device. The machine should complete vari
5、ous of functions including the accuracy requested, on this foundation, decrease the cost of design and the manufacturing as far as possible. I use two air cylinder to control the pressure between two stalks, and also reduce the workers labor strength, so save the human resource, I use a Decelerating
