摘   要

     在參考國(guó)內(nèi)外有關(guān)中厚煤層采煤機(jī)的情況下，完成了截割電機(jī)功率為180KW總裝機(jī)功率為450KW的截割式滾筒液壓牽引采煤機(jī)的整機(jī)方案設(shè)計(jì)及對(duì)采煤機(jī)截割部進(jìn)行了重點(diǎn)設(shè)計(jì)。主機(jī)身采用整體結(jié)構(gòu)形式，取消了長(zhǎng)螺柱及傳統(tǒng)意義上的螺栓聯(lián)接；此結(jié)構(gòu)簡(jiǎn)單、可靠，且尺寸小，大大的降低了采煤機(jī)的機(jī)身高度。截割部采用四級(jí)傳動(dòng)前三級(jí)為直齒傳動(dòng)，第四級(jí)為行星傳動(dòng)。在前三級(jí)的直齒傳動(dòng)利用直齒傳動(dòng)設(shè)計(jì)的一般原理，設(shè)計(jì)出適合截割部的齒輪傳動(dòng)依次分為截一軸系，惰一軸系，截二軸系，截三軸系，，惰二軸系；采用了兩個(gè)惰軸系是本設(shè)計(jì)的創(chuàng)新點(diǎn)，它即滿足了傳動(dòng)強(qiáng)度的要求又滿足了截割高度對(duì)截割部長(zhǎng)度的要求。在第四級(jí)行星傳動(dòng)中，用運(yùn)2KH行星減速器設(shè)計(jì)的原理，設(shè)計(jì)出適合截割部的一級(jí)2KH型行星減速器，并將它和滾筒直接聯(lián)結(jié)，大大簡(jiǎn)化了截割部的設(shè)計(jì)，節(jié)省了材料、空間。此外對(duì)截割部上的其它部分如離合器，內(nèi)噴霧系統(tǒng)也進(jìn)行了詳細(xì)設(shè)計(jì)及校合。

ABSTRACT

Reference to the domestic and international thick seam Shearer circumstances, Cutting completed the electrical power of 180 KW total installed power of 450 KW of cutting-cylinder hydraulic traction Shearer Whole program design and right shearer cutting focus of the Department of Design. Host overall body structure, eliminating a long stud, and the traditional sense of the bolt; This structure is simple, reliable, and small size, greatly reducing the height of Shearer's fuselage. Cutting Part 4 used to drive before three straight tooth drive, the fourth level of planetary transmission. The former three straight drive gear teeth through the direct transmission of the general design principles, designed for cutting the Department of Gear were divided into a closed shaft, the shaft an inert, as of two shaft, up 3 shaft, and inert two shafts; using two inert shaft is the innovation in design, It is a drive to meet the strength to meet the demands of the cutting height on the cutting Minister degree requirements. In the fourth grade planetary transmission, and use Win two KH planetary reducer design principle, designed for cutting the Department of a two-KH planetary reducer, and it will directly link drum, greatly simplified the cutting of the design, saving materials and space. In addition to cutting the Department of the other parts such as clutch, which spray system also carried out a detailed design and a calibration.
