The strongpoint of this industry is have great output of the production is the variety production. and the produce process is very mechanization and steeling is a important technology to fulfill the country with the development of steeling industry the industry integrate very well with the traditional mechanism industry. How to make use of the steeling manufacture technology, enhance the rolling quality of the production, decrease the product of rolling time,enhance the rate of product useful rolled steel .The straighting technology is a important tache to enhance the surface quality and flatness of the production .This article describes the reasons inflatedness occurred on medium and heavy plate． The type of levelers， the determination of basic parameters， energetic date for 2600 plate leveler,the decision for plete structure and design， the development of plate leveling technology .This article design basis on the boardstrip straighting machine produce process and the working principle in the steel metallurgy. This article first begin with the scheme review of the energetic date for 2600. Then go along with choice of the pressure electromotor, the design and checking of pressing the nut and the pressure screw, Worm and worm gear design and checking the life of the designed the local assessor and the over all structure. Besides researched the development direction of the straighting machine . Keywords: Pressure system。 Correction force。 flatness 目錄 遼寧科技大學(xué)本科生 畢業(yè)設(shè)計 第 III 頁 1. 緒論 .............................................................................................................. 1 矯正機現(xiàn)狀 ................................................................................................................. 1 輥式矯正機的發(fā)展趨勢 .............................................................................................. 1 輥式矯正機的分類 ...................................................................................................... 2 矯正機壓下系統(tǒng) .......................................................................................................... 2 輥式矯正機原理 .......................................................................................................... 3 國內(nèi)外概況和預(yù)測 ...................................................................................................... 3 矯正機壓下機構(gòu)的研究內(nèi)容 ...................................................................................... 3 ........................................................................................................ 5 矯正機壓下方案 .......................................................................................................... 5 矯正工藝 ...................................................................................................................... 6 上排工作輥整體平行調(diào)整 ............................................................................... 6 總體結(jié)構(gòu)設(shè)計 .............................................................................................................. 6 壓下裝置的組成 ............................................................................................... 6 電動機 ............................................................................................................... 7 減速機 ............................................................................................................... 7 聯(lián)軸器 ............................................................................................................... 7 ................................................................................................. 9 矯正機結(jié)構(gòu)參數(shù)的確定 .............................................................................................. 9 矯正扭矩 kM 的確定 .................................................................................................. 10 各輥矯直力 P的計算 ................................................................................................ 11 壓下螺絲主要參數(shù)計算 ........................................................................................... 11 電機的選擇 ................................................................................................................ 13 傳動比的分配 ............................................................................................................ 13 ........................................................................................... 15 材料的選擇 ................................................................................................................ 15 蝸輪蝸桿的參數(shù)計算 ............................................................................................... 15 蝸桿的校核 ............................................................................................................... 17 校核齒根彎曲疲勞 強度 ................................................................................. 17 蝸桿剛度的校核 ............................................................................................. 18 ....................................................................... 20 螺母的尺寸計算
