摘 要
MG180/435-W型液壓牽引采煤機主要用于中厚煤層的綜采作業(yè)。它可以一次采全高，并且能適應煤層厚度變化和底板起伏不平的條件。該采煤機適應性好、功率大、采煤效率高、操作簡單、檢修方便。本設計主要針對采煤機的整機進行方案設計，對截割部進行結構及傳動等相關設計。MG180/435-W型液壓牽引采煤機采用彎搖臂截割部，截割電機橫向布置在搖臂上，搖臂和機身連接沒有動力傳遞，取消了螺旋傘齒輪和結構復雜的通軸。在截割部傳動設計中，利用直齒輪和行星齒輪組成減速器是設計的一般原理，設計出適合截割部使用的減速器，并將它和礦用電動機直接聯結，簡化了截割部的傳動布置。本設計的創(chuàng)新點：把截割部的減速器安裝在搖臂里，使用了兩個惰輪來增加中心距，這樣也使齒輪的總個數減少，提高了傳動效率。結構上將離合器安裝在電機軸上，使制動變的方便安全。設計中對2K(Ⅰ)型行星減速器進行了優(yōu)化配齒，采用高度變位，并做了相應的校核，在保證需要的傳動比的情況下，使設計的2K(Ⅰ)型行星減速器體積最小。

ABSTRACT
The MG180/435-W type liquid presses to lead to shearer to mainly used for the medium thick coal seam to adopt homework. It can cuts the whole seam height in one trip, and accommodate the changing of seam thickness and floor undulation. Should the shearer adaptability like, the power is big and adopt a coal efficiency high, operate in brief and check to fix convenience. This design mainly carrieson a project design to the whole machine of the shearer, spreading to move to wait a related design towards the cutting drum to carry on structure. The MG180/435-W type liquid presses to lead to shearer curved the ranging arm of the cutting drum, and the electrical engineering horizontal arranges in the ranging arm. There is no motive delivering between ranging arm and gearhead conjunction and canceling spiral umbrella wheel gear and structure a complicated stalk. In the design of the cutting drum spread move , the exploitation keeps the general theory that wheel gear and planet wheel gear's constituting to decelerate a machine is a design. Designing to suit a deceleration machine which mows an usage, and will it and the mineral use electric motor to combine directly, simplifying to the cutting drum to spread to move a decoration. The creative of this design: Cut a deceleration machine of mowing the department to install in the ranging arm, used two round to increase center to be apart from, so as to make the total piece of wheel gear reduced, and raised to spread to move an efficiency. The structure full general clutch installs on the electrical engineering stalk, making the moving convenience and safety. In the Design medium to 2K(Ⅰ) type the planet decelerated a machine to carry on excellent turn to go together with teeth, adopt height to change, and did a homologous check. Be promising to need of spread under circumstance of moving the ratio, make the 2K(Ⅰ) of design type planet decelerate machine physical volume minimum.
