摘 要
本設計是關(guān)于對稱式三輥卷板機的設計，主要對卷板機上、下輥及減速器進行設計和計算。
設計前部分詳細闡述了卷板機上、下輥結(jié)構(gòu)設計和受力分析。板機結(jié)構(gòu)型式為三輥對稱式, 在該結(jié)構(gòu)中上輥下壓提供壓力,兩下輥做旋轉(zhuǎn)運動,為卷制板材提供扭矩。它具有結(jié)構(gòu)簡單、體積小、重量輕、經(jīng)濟、等優(yōu)點。動力源則選擇了YZ系列YZ160L—6型電機，其工作特性優(yōu)于Y系列電機，適用于有輕微震動，正反轉(zhuǎn)且轉(zhuǎn)速不高的場合。
總體設計后部分所涉及的減速器采用了三級展開式圓柱齒輪結(jié)構(gòu)。齒輪材料為40Cr，并經(jīng)調(diào)質(zhì)及表面淬火。校核齒輪、軸、鍵、軸承確保了設計的實際可行性。

ABSTRACT
This design is about the three-roller symmwtry rolling machine,mainly calcats the up and down roller and the decelerator
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 system.It has a series of advantages such as simply structure,small volume,light weight,economical and so on.YZ 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 expanding columm gear constiuction .The material of gear is 40Cr which has been hardening surface.The gears, axes, keys, bearings are checked, so to confirm this design is practical
Key words: Rolling machine；Motor；Decelerator；Key；Gear
