摘 要本次設(shè)計參照了太原煤科院研制生產(chǎn)的 EBJ-120TP 型掘進機，這是一種中型懸臂式掘進機，主要用于中型煤巷及半煤巖巷的掘進作業(yè)。它結(jié)構(gòu)緊湊、適應(yīng)性好、機身矮、重心低、操作簡單、檢修方便。我的設(shè)計主要針對掘進機的行走部進行結(jié)構(gòu)及傳動等相關(guān)設(shè)計。設(shè)計中采用履帶式行走部，驅(qū)動動力由液壓馬達提供，利用液壓馬達轉(zhuǎn)動方向變化實現(xiàn)行走部前進、后退和轉(zhuǎn)向。在行走部傳動設(shè)計中，采用高速直聯(lián)液壓馬達接一級圓柱直齒輪傳動再接 3K(Ⅱ)型行星傳動的設(shè)計方案，通過制動器并將它和液壓馬達聯(lián)結(jié)，制動器內(nèi)圈懸浮,既起到制動功能又起聯(lián)軸器作用，源頭制動使制動性能更可靠。本設(shè)計的創(chuàng)新點：用制動器替代了聯(lián)軸器。減速器安裝時左右兩側(cè)的減速器對調(diào) 180 度錯開布置。充分利用空間，使結(jié)構(gòu)緊湊。關(guān)鍵詞：懸臂式掘進機 ；行走部 ；行星減速器 ；制動器 ； 行星齒輪ABSTRACTThis design References the EBJ-120TP tunneling machine which is designed by Coal Science Research Institute in Taiyuan. It is one kind of medium cantilever tunneling machine which is mainly used in the medium coal lane and the half coal crag lane digging the tunnels, its structure compact, the compatibility good, the fuselage short, the center of gravity low, the operation simple, the overhaul is convenient. My design mainly aims at the tunneling machine’s walks-organization. I try to carry on the design of its structure and transmission.It uses marching walks organization, the actuation power provides by the oil motor, using the change of the oil motor’s rotation direction to make the walks-organization advance, retrocede, and turn. In the transmission design of the walks organization, using High-speed hydraulic motor to connect a pair of cylindrical Gear then connect a 3 K (II) type planetary gear, and uses the brake to link hydraulic motors Brake Inner Ring suspended can brake and link, and the source of more reliable braking performance. The innovation in designing: Use braking instead of coupling; when reducer is installed ,at each side of the reducer reversed 180 degrees staggered layout. Make full use of space and compact structure.Keywords：Cantilever tunneling machine; Walks-organization; Planet reduction gear; Brake, Planetary gear
