摘 要
礦山提升設(shè)備是礦山運(yùn)輸中的咽喉設(shè)備，占有特殊地位，是井下與地面聯(lián)系的主要工具。
礦山提升設(shè)備的用途是沿井筒提運(yùn)礦石和廢石，升降人員，下放材料、工具和設(shè)備。礦山提升設(shè)備在工作中如果一旦發(fā)生機(jī)械和電氣故障就會(huì)造成停產(chǎn)，甚至人身傷亡。為了保證生產(chǎn)和人員的安全要求礦山提升設(shè)備運(yùn)行準(zhǔn)確，安全可靠，井必須配有性能良好的控制設(shè)備和保護(hù)裝置。
礦山提升設(shè)備的耗電量一般占礦井總耗電量的30%一40%，所以為了降低礦石的成本，必須經(jīng)濟(jì)合理地選擇和使用礦山提升設(shè)備。礦山提升設(shè)備又是礦井最大固定設(shè)備之一，是—套較復(fù)雜的機(jī)械-電氣機(jī)組。
這篇畢業(yè)設(shè)計(jì)的論文主要闡述的是一套系統(tǒng)的關(guān)于環(huán)面蝸輪蝸桿減速器的設(shè)計(jì)方法。環(huán)面蝸輪蝸桿減速器是蝸輪蝸桿減速器的一種形式.這個(gè)方法是以加工過(guò)程和蝸輪減速器的使用條件的數(shù)學(xué)和物理公式為基礎(chǔ)的。
目前，在環(huán)面蝸輪蝸桿減速器的設(shè)計(jì)、制造以及應(yīng)用上，國(guó)內(nèi)與國(guó)外先進(jìn)水平相比仍有較大差距。國(guó)內(nèi)在設(shè)計(jì)制造環(huán)面蝸輪蝸桿減速器過(guò)程中存在著很大程度上的缺點(diǎn)，正如論文中揭示的那樣，重要的問(wèn)題如：輪齒的根切；蝸桿毛坯的正確設(shè)計(jì)；蝸輪蝸桿的校核。

ABSTRACT
The mine lift technique is in the mine haulage pharynx and larynx equipment, holds the special status, and is the mine shaft and the ground relation main tool.
The mine lift technique use is picks up and ships the ore and the scrap rock along the well chamber, the fluctuation personnel, the release material, the tool and the equipment. Mine lift technique in work once if has the machinery and the electrical failure can create the production suspension, even person casualties. In order to guarantee the production and personnel's safety requirements mine lift technique movement is accurate, safe reliable, the well must have the performance good control device and the protective device.
The mine lift technique power consumption occupies the mine pit total power consumption generally 170%, therefore in order to reduce the ore the cost, must the economical reasonably choice and the use mine lift technique. The mine lift technique also is one of mine pit most greatly fixed equipments, is the complex machinery - electricity unit.
This paper of graduation project mainly presents a systematic approach for the design of circular worm gear reducer . circular worm gear reducer is one of the members in the worm gear reducer family . the approach is based on the mathematical formulations and physical formulation on the generation process and conditions for the type of worm reducer .
At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of fault in the design of circular worm gear reduce. As can be revealed from the literature search , important problem such as： tooth undercutting ；proper design of worm gear blank；computations of worm and label gear.
Key words: Lifting hoist ；reducer ；worm ；ge
