摘 要
機(jī)械化運(yùn)送越來(lái)越廣泛的得到應(yīng)用,近年來(lái)已成為發(fā)展最迅速的行業(yè)之一在機(jī)械化輸送的領(lǐng)域里,鏈條輸送既能實(shí)現(xiàn)垂直,水平,傾斜,彎曲及相互組合的各種輸送軌跡,又能適應(yīng)散裝,帶裝等各種類型的物料搬運(yùn);既能滿足運(yùn)行平穩(wěn),低速輸送和節(jié)拍可控的自動(dòng)化生產(chǎn)先的工況要求,又能在惡劣的環(huán)境里可靠的工作,鏈條輸送機(jī)作為性能良好的連續(xù)輸送機(jī),它可以不停的在同一方向運(yùn)輸物料,裝卸無(wú)須停機(jī),具有很高的生產(chǎn)率. 由于鏈條輸送機(jī)供料均勻與運(yùn)行速度穩(wěn)定,工作過(guò)程中消耗的功率變化不大,因而驅(qū)動(dòng)裝置功率較小 鏈條輸送機(jī)的重要功能元件是輸送鏈,而鏈條的結(jié)構(gòu)是千變?nèi)f化的,所以鏈條輸送機(jī)能適用于眾多的使用環(huán)境和眾多的使用要求.與帶傳動(dòng)相比, 鏈傳動(dòng)沒(méi)有彈性滑動(dòng)和打滑,能保持準(zhǔn)確的平均傳動(dòng)比,傳動(dòng)尺寸比較緊湊,不需要很大的張緊力,作用在軸上的載荷也小;承載能力大;效率高 ,如果溫度較高,在這樣的環(huán)境下如果我們采用帶傳動(dòng),帶子的壽命會(huì)很短,而且實(shí)際情況會(huì)更糟,采用齒輪傳動(dòng),可能情況也沒(méi)什么差別, 在低速運(yùn)行大中心距的情況下,與齒輪傳動(dòng)相比,鏈傳動(dòng)能吸振與緩和沖擊,結(jié)構(gòu)簡(jiǎn)單,加工成本低廉,安裝精度要求低.

Abstract
Mechanization transit more and more extensive get application, have become in recent years develop the most quick profession one in mechanize transport field in, chain transport can realize vertical, level, incline , bend and make up mutually various transport locus, can again meet bulk, take pack wait for the stock of various types carry ; can satisfy operation steady, transport at low speed may control with metre automation production the late requirement of operating mode, again can in bad environment in reliable work, chain conveyer is performance good continuous conveyer, it need not stop in same one side to transportation stock, load and unload need not stop machine, have very high productivity. Since chain conveyer is let , expects , is even , is steady with traversal speed, the power change that consumed in working process is not large , thus the power of actuating device less prick Jia Lu suddenly make noise signboard sheath Lu earth the structure of chain is ever changing, so chain conveyer can apply to numerous use environment and numerous use ask . compare with , chain transmission with tape transmission have no elasticity slide with hit slippery, can maintain accurate average transmission compare than, transmission size compact, do not need great tensile force, take affect in axle on load also little; bearing capacity big; efficiency is positive drive high , if temperature higher, in such environment take off if we can be the condition of big central distance at low speed short very much with the life of tape transmission and belt, also actual condition can go bad more, adopt , possible condition also sink what difference, in run compare with , chain transmission with positive drive can inhale shake lash with mitigation, structure simple, finished cost cheap, installation precision requirement low.
