摘要
提升機(jī)是一種實(shí)現(xiàn)工程物料向上運(yùn)輸?shù)臋C(jī)械，它是當(dāng)代最為得力的輸送設(shè)備之一，它廣泛運(yùn)用于礦山、碼頭、化工等各種場合，但是不同的工況下它對(duì)設(shè)備的要求是不同的
本文以食品加工業(yè)為背景，設(shè)計(jì)提升食品的機(jī)械。食品提升皮帶機(jī)是在帶式輸送機(jī)的基礎(chǔ)上發(fā)展起來的。食品提升皮帶機(jī)與傳統(tǒng)的帶式輸送機(jī)一樣是以膠帶、鋼帶、鋼纖維帶、塑料帶和化纖帶等作為傳送物料和牽引工件的輸送機(jī)械。其特點(diǎn)是承載物料的輸送機(jī)也是傳遞動(dòng)力的牽引件，這與其他輸送機(jī)械有著顯著的區(qū)別。本次設(shè)計(jì)的食品提升皮帶機(jī)是一種小型的運(yùn)輸機(jī)械，其承載能力要求較小，相對(duì)于其他的帶式輸送機(jī)成本要求低，設(shè)計(jì)結(jié)構(gòu)緊湊。
本設(shè)計(jì)從整體結(jié)構(gòu)出發(fā)，對(duì)整個(gè)裝置中的驅(qū)動(dòng)部分和傳動(dòng)部分進(jìn)行了設(shè)計(jì)與計(jì)算。其中在驅(qū)動(dòng)裝置的設(shè)計(jì)與計(jì)算中，本設(shè)計(jì)選擇電機(jī)—減速器的裝置來作為驅(qū)動(dòng)設(shè)備；而在傳動(dòng)部分的設(shè)計(jì)中，本設(shè)計(jì)選擇了同步帶輪與驅(qū)動(dòng)裝置相連，從而傳遞動(dòng)力。本文另外還對(duì)裝置中的改向滾筒、壓輥及機(jī)架部分進(jìn)行了選擇設(shè)計(jì)，同時(shí)對(duì)其他的輔助設(shè)備也做了必要的計(jì)算和選擇。
本設(shè)計(jì)主要設(shè)計(jì)減速器的結(jié)構(gòu)，確定了內(nèi)部各傳動(dòng)齒輪以及軸的各主要參數(shù)，以及改向滾筒的設(shè)計(jì)，并對(duì)其工作原理作了詳細(xì)分析。

Abstract
Hoist is a progressive realization of the transport of materials engineering machinery, it is the most modern equipment capable of conveying one of its widely used mines, docks, chemical and other occasions, but a different condition of its equipment requirements are different The
In this paper, food processing industry as the background, design enhance food machinery. Enhancing food in the belt conveyor belt machine is developed on the basis of. Food and upgrade the traditional belt machine, like a belt conveyor belt, strip, with steel fibers, plastics and chemical fibers with a transmission belt, and other materials and the delivery of mechanical traction workpiece. Its characteristics are carrying the material conveyor is also the change of power transmission parts, machinery and other transport has significant differences. The design of the food enhance belt machine is a small transport machinery, its carrying capacity requirements of small, relative to other low-cost requirements of the belt conveyor, compact design.
The design of the overall structure of the entire device in the drive and drive some parts of the design and calculation. One driver in the design and calculation, the electrical design options - as a reducer of the device to drive equipment in the transmission part of the design, selected the design of the timing belt pulleys connected with the drive to transfer power . This paper was also installed in the bend of the drum, roll and rack some pressure to choose a design, while the other auxiliary equipment have also done the necessary calculations and choices.
The main design reducer design the structure, determining the internal transmission gear and the axis of the main parameters, and bend the drum design, and the principle of detailed analysis.
Keywords: Reducer Bend pulley Pressing wheel Roller
