摘 要
機械化運送越來越廣泛的得到應用,近年來已成為發(fā)展最迅速的行業(yè)之一在機械化輸送的領域里,鏈條輸送既能實現垂直,水平,傾斜,彎曲及相互組合的各種輸送軌跡,又能適應散裝,帶裝等各種類型的物料搬運;既能滿足運行平穩(wěn),低速輸送和節(jié)拍可控的自動化生產先的工況要求,又能在惡劣的環(huán)境里可靠的工作,鏈條輸送機作為性能良好的連續(xù)輸送機,它可以不停的在同一方向運輸物料,裝卸無須停機,具有很高的生產率. 由于鏈條輸送機供料均勻與運行速度穩(wěn)定,工作過程中消耗的功率變化不大,因而驅動裝置功率較小 鏈條輸送機的重要功能元件是輸送鏈,而鏈條的結構是千變萬化的,所以鏈條輸送機能適用于眾多的使用環(huán)境和眾多的使用要求.與帶傳動相比, 鏈傳動沒有彈性滑動和打滑,能保持準確的平均傳動比,傳動尺寸比較緊湊,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,帶子的壽命會很短,而且實際情況會更糟,采用齒輪傳動,可能情況也沒什么差別, 在低速運行大中心距的情況下,與齒輪傳動相比,鏈傳動能吸振與緩和沖擊,結構簡單,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.
