摘 要
單繩纏繞式礦井提升機(jī)的工作原理:鋼絲繩的一端用鋼絲繩夾持固定在卷筒幅板上,另一端經(jīng)卷筒的纏繞后,通過(guò)井架天輪懸掛提升容器。這樣,利用主軸旋轉(zhuǎn)方式的不同,將鋼絲繩纏繞上或放松,以完成提升或下降容器的工作。
主軸是單繩纏繞式礦井提升機(jī)的主要結(jié)構(gòu),它的作用是:①支撐纏繞提升機(jī)鋼絲繩的卷筒;②承受各種正常載荷(包括固定載荷和工作載荷);③承受各種積極情況所造成的非常載荷。在非常載荷作用下,主軸部分不應(yīng)有殘余變形。減速器要滿足傳動(dòng)比要求,保證提升機(jī)正常工作,傳動(dòng)應(yīng)準(zhǔn)確,平穩(wěn),可靠。減速器應(yīng)該在滿足強(qiáng)度條件的同時(shí)盡可能小型,以減少占用空間。單繩纏繞式礦井提升機(jī)的主軸和減速器是其核心部件,要求我們應(yīng)認(rèn)真設(shè)計(jì),精心制造,這對(duì)于確保礦井提升機(jī)安全可靠運(yùn)行,預(yù)防和杜絕故障及事故的發(fā)生,也具有十分重要的意義。
本設(shè)計(jì)根據(jù)生產(chǎn)實(shí)際和預(yù)選的數(shù)據(jù),以提升機(jī)的配套設(shè)備為核心,經(jīng)過(guò)科學(xué)的計(jì)算和分析,設(shè)計(jì)了礦井提升機(jī)的傳動(dòng)系統(tǒng)。

ABSTRACT
What the principle of the single rope twines mine pit elevator is that: One end of the steel wire rope is fixed to winding by the steel wire rope nip, a nother end after twined hangs and promotes the vessel by derrick wheel. In this way, we make use of the differences of the revolve way to twine or relax the steel wire rope so that to complete the vessel to step up or drop down.
Main axle is the core part of the mine elevator. Its functions are: ① the steel wire rope of twines the type mine pit elevator ; ② endure a kind of normal load( including fixed load and work load ); ③ endure the kinds of unusual load which is result from positive situation. Under the unusual load function, the part of the main axle equipment should not remain remaining distortion. The decelerator should meet the need of reduction rate to make the elevator fuction well. The transmission should be accurate, steady, and reliable. The decelerator should be as small as possible to decrease the space it takes. It required us to be careful designing and manufacturing when. Only in this way can we prevent the occurrence of failures or accidents .Obviously, the processes is very significant.
This design is on the basis of the data which are chosen by advance and actually, take the elevator supplementary equipment as the core, after the analysis and computation in science, has designed and chosen a set of the transmission system of the mine pits elevators.
KEY WORDS: elevator, main axle, decelerator
