摘 要
我國薄煤層資源豐富，可采儲量約占總可采儲量的19%，而且分布廣、煤質(zhì)好。薄煤層采煤機械化經(jīng)過多年的發(fā)展，取得了一定的成效，但由于薄煤層采煤工作面生產(chǎn)條件艱難，長期存在推進速度慢，效率低、經(jīng)濟效益差等突出問題。特別是有些礦井厚、薄煤層并存，薄煤層作為解放層開采，由于薄煤層開采速度緩慢，使下部厚煤層資源長期得不到開采，影響采煤工作面的正常接替，甚至被迫丟失一部分薄煤層資源。研制適合的薄煤層采煤機,以適應不同的煤層結(jié)構,提高薄煤層采煤的工作效率是當務之急。
雖然薄煤層采煤機的型號、規(guī)格有許多,但它的各主要組成部分大同小異，合理選擇薄煤層采煤機的截割部的參數(shù)，可以改善其工作性能和減少采煤比能耗。選擇這個題目就是要進一步熟悉薄煤層采煤機各部分的工作原理，對其進行更好的改進，并對它的截割部減速器進行細致分析設計，使其耐用并且省時省力容易裝修，使其在工作中能夠有更好的經(jīng)濟效益。對于現(xiàn)在使用較為廣泛的薄煤層采煤機的減速器中存在的錐齒輪，影響電動機的安放和使用壽命，針對此處進行改進。
關鍵詞：薄煤層采煤機；截割機構；減速器。
Abstract
Thin seam in China is rich in resources, recoverable reserves total recoverable reserves of 19 percent, and widely distributed, coal good. Thin seam coal mining mechanization after years of development, has achieved some results, but because of thin seam coal face difficult production conditions, promote the long-standing slow, low efficiency, poor outstanding problems in economic benefits. Especially some of mine thick, thin seam coexist as a liberation layer thin seam mining, as a result of the slow pace of thin coal seam, so that the lower part of thick coal seam is not a long-term exploitation of resources, affecting the normal coal face to succeed, and even forced the loss of part of a thin coal resources. Development of suitable thin seam shearer in order to adapt to different seam structure and improve the thin seam coal mining efficiency is a priority.
Although the thin coal seam shearer models, specifications there are many, but it is the major component of the more or less the same, a reasonable choice of thin coal seam shearer cutting unit parameters, can improve its performance and reduce power consumption than coal. Choose this subject is to become more familiar with the thin coal seam shearer parts of the working principle, its better to improve, and its cutting unit carried out a detailed analysis of reducer design, make it durable and easy to save time and manpower on decoration, their work can have a better economic benefits. For now the more extensive use of thin coal seam shearer reducer existing bevel gears, the impact of the installation and service life of electric motors for improved here.
Key words: thin coal seam shearer; cutting institutions; reducer.
