In order to bine theory with practice. Learn how to make mechanical design, understand the principles and parameters of mechanical transmission devices. Learn how to use a variety of tools, such as AutoCAD, visually renders mechanical structure on the floor plan. Through the design of cylindrical gear reducers for singlestage cylindrical gear reducers have a simple understanding and awareness. Gear reducers are an integral part of the mechanical transmission devices. Mechanical transmission devices in constant use, with varying degrees of wear and tear, so regular maintenance for machinery, to extend its service life, efficient running, improving the efficiency of production. Keywords: Mechanical gearing,Gear reducers,Design principles and parameters are configured 中北大學(xué) 2021 屆畢業(yè)設(shè)計說明書 第 Ⅰ 頁 共 Ⅱ 頁 目 錄 1 緒論 ...................................................................................................................................... 1 2 減速器概述 .......................................................................................................................... 4 減速器的主要型式及其特性 ........................................................................................... 4 減速器結(jié)構(gòu) ....................................................................................................................... 4 減速器潤滑 ....................................................................................................................... 5 3 減速機設(shè)計計算 .................................................................................................................. 7 選擇電動機： ................................................................................................................... 7 選電動機類型 ................................................................................................................ 7 確定電動機轉(zhuǎn)速 ............................................................................................................ 7 確定電動機的型號 ........................................................................................................ 7 傳動比： ........................................................................................................................... 7 4 齒輪的選擇 .......................................................................................................................... 8 齒輪傳動的設(shè)計計算 ....................................................................................................... 8 選擇齒輪材料及精度等級 ............................................................................................ 8 按齒面接觸疲勞強度設(shè)計 ............................................................................................ 8 轉(zhuǎn)矩 T1 ........................................................................................................................... 8 載荷系數(shù) k ..................................................................................................................... 8 許用接觸應(yīng)力 [σH] ......................................................................................................... 8 校核齒根彎曲疲勞強度 ................................................................................................ 9 齒形系數(shù) YFa 和應(yīng)力修正系數(shù) YSa .............................................................................. 9 許用彎曲應(yīng)力 [σF] .......................................................................................................... 9 計算齒輪傳動的中心矩 a ........................................................................................... 10 計算齒輪的圓周速度 V ............................................................................................ 10 5 減速器的軸及軸上零件的結(jié)構(gòu)設(shè)計 ................................................................................ 11 軸的結(jié)構(gòu)設(shè)計 ................................................................................................................. 11 階梯軸各段直徑 的確定 ....................
