本设计是关于对称式三辊卷板机的设计,主要对卷板机上、下辊及减速器进行设计和计算。
位置的分析和经验模型本文研究的水平对称式卷板机特点如下:采用水平下调式,即下辊可作水平移动,可实现不用调头便可预弯端头,使进料、对中、预弯、卷圆、矫圆整个卷板过程连续完成,利于提高生产效率,降低工人劳动强度;设置板料对中装置和支承辊装置,利于提高卷板精度和卷板质量;采用全液压驱动,使设备结构简化,便于卷板过程中的速度和压力控制,起停、换向灵活,运行平稳,操作方便;结构简单, 便于操作和维护维修,符合现场技术工人的操作和维修水平,高效实用。
设计前部分详细阐述了卷板机上、下辊结构设计和受力分析。板机结构型式为三辊对称式, 在该结构中上辊下压提供压力,两下辊做旋转运动,为卷制板材提供扭矩。它具有结构简单、体积小、重量轻、经济、等优点。动力源则选择了YZ系列YZ160L—6型电机,其工作特性优于Y系列电机,适用于有轻微震动,正反转且转速不高的场合。
总体设计后部分所涉及的减速器采用了三级展开式圆柱齿轮结构。齿轮材料为40Cr,并经调质及表面淬火。校核齿轮、轴、键、轴承确保了设计的实际可行性。

Abstract
This design is about the three-roller symmwtry rolling machine,mainly calcats the up and down roller and the decelerator.
The charact type of level eristic of level adjust below three rollers Rolling Machine in thisinvestigation is as the adjust,the end can be bendedwithout turn around and the whole process of plate coiling including entering、center adjusting、pre-bending、coiling、cylinder proofread can pletedcontinuously;due to whole hydraulic pressure driving protocol,the structure wassimplified,and speed and pressure was easily controlled in the process of platecoiling;The setup of the center adjusting and the equip of supporting,the preciseand quality of plate coiling was improved;owing to the simplified structure,theoperation and maintenance is easy to carried out.
During the front process of the design,the rolling machine`s structucre design and the analysis of strength are described. The rolling machine` structure is three-roller symmetry. Pressure provides pressure under owing structure the above-average roller , the roller does revolution sport under two , sheet material provides moment of torsion to roll of has a series of advantages such as simply structure,small volume,light weight,economical and so type YZ-160L-6 motor is selected as the power source,which adapts situation such as slience quenching and light reverse velocity.
The last part of the paper is ahout decelerator which is choosing triple e
