The main purpose is to transfer the motion of the high speed low torque device through relevant mechanical mechanism into a low speed high torque transmission. Main task is to design and plete the reducer gear in puting and assembly, the main task contain the choice of motor to the belt transmission design and calculation, to the design and calculation of gear and shaft design and calculation, finally according to the size of the selected gear and shaft in accordance with the relevant standard plete enclosure design and other related parts and ponents selection. The most important part of this design is the core of gear transmission part of the selection calculation and design calculation and check of each gear shaft is chosen in the design of helical gear, chose a helical gear is mainly in order to ensure the stability of the transmission and the use of the relationship between the two vice gear and reverse loading offset part of the axial force, residual axial force to offset by selecting the appropriate bearing, tapered roller bearings are the main choice in the design. Another window of this design is to use puter instead of traditional manual calculation, the main use is the Solidworks software, the software is mainly used to plete the 3D entity model, and then through the explosion view more clearly express of the structure principle to this device, and the use of the software of puting functions is to plete the checking calculation of gear and shaft.Keywords: gear; drive shaft; transmission ratio。設(shè)計的主要目的在于將高轉(zhuǎn)速小扭矩的運動裝置通過相關(guān)機械機構(gòu)轉(zhuǎn)換為低轉(zhuǎn)速大扭矩的傳動裝置。主要任務(wù)是進行結(jié)構(gòu)設(shè)計并完成減速機中傳動裝置的計算以及裝配,設(shè)計主要從電動機的選擇到帶傳動的設(shè)計計算,再到齒輪的設(shè)計計算以及軸的設(shè)計計算,最后根據(jù)所選齒輪以及軸的尺寸根據(jù)相關(guān)標準完成箱體的設(shè)計以及其它相關(guān)零部件的選擇。;transmission efficiency 47 目 錄摘 要 IAbstract II緒 論 1 1.電動機的選擇 4 5 6 6 6 7 7 7 8 8 8 9 9 9 : 11 : 13 14 15 Solidworks進行齒輪的算例分析 15 17 : 19 : 21 22 22 Solidworks進行齒輪的算例分析材料屬性 23 27 27 。它的輸送能力大、功耗小、結(jié)構(gòu)簡單、對物料適應(yīng)性強,因此應(yīng)用范圍很廣。按皮帶種類的不同,帶式輸送機可分為普通帶式輸送機、鋼絲繩芯帶式輸送機和高傾角花紋帶式輸送機;按驅(qū)動方式及膠帶支承方式的不同,又可分為普通帶式輸送機、氣墊帶式輸送機和鋼絲繩牽引帶式輸送機;按托輥槽角的不同,還可分為普通槽角帶式輸送機和深槽形帶式輸送機。帶式輸送機的工作原理如圖61所示。帶式輸送機按連續(xù)運輸特性可分為:(1)具有撓性牽引物件的輸送機,如帶式輸送機,板式輸送機,刮板輸送機,斗式輸送機、自動扶梯及架空索道等。移動工帶式輸送機適用于零星分散煤堆的轉(zhuǎn)運,由于結(jié)構(gòu)笨重,移動困難,目前制造廠生產(chǎn)的移動帶式輸送機帶寬為400~800mm,~25m/s,傾角為00~200,長度一般在5~20m范圍內(nèi)。固定式帶式輸送機目前生產(chǎn)的有輕型(QD型)、普通型(TD62型、TD72型、TD75型)、鋼繩芯高強度型以及其他類型帶式輸送機,如大傾角帶式輸送機(GH69型)、可彎曲帶式輸送機、移置式帶式輸送機、吊掛式帶式輸送機、壓帶式帶式輸送機、氣墊式帶式輸送機、磁性帶式輸送機、鋼繩牽引帶式輸送機、鋼帶輸送機、網(wǎng)帶輸送機。.⑸..:輸送物料的最大傾角可達90176。帶式輸送機的一般要求:在曲線段內(nèi),不允許設(shè)備給料和卸料裝置,各種卸料裝置應(yīng)設(shè)于水平段。由[2]表86和表88取主動輪基準直徑 =80 mm根據(jù)[2]式(815), 從動輪基準直徑 。那么大齒輪齒數(shù)為81。
