摘  要

隨著我國煤炭、冶金礦山向大型化發展，以大型破碎站為關鍵設備的半連續開采工藝得到了廣泛的應用。而大型破碎站的主機設備一直依賴于歐、美發達國家的產品。因此，開發高效節能新型破碎設備、替代進口、滿足國內大型礦山的需要勢在必行。
我國大型露天煤礦可移式破碎站始于90年代。其破碎性能僅能滿足煤及較軟剝離物的破碎，使用受到了限制，不能滿足礦山使用要求。而本論文研究的高效錘式破碎機由于其結構上獨特的優點，使得生產能力大、破碎硬度高、破碎比大、排料粒度均勻、過粉碎小。因此，該破碎機是一種發展前途廣闊的高效破碎設備。
本文完成了綜采工作面錘式破碎機的整機外形的布局設計，介紹了各類型破碎機的應用和工作原理，以及目前國內破碎機的現狀和發展趨勢，結合破碎能力及要求采用一級錐齒減速；闡述了齒輪失效的條件；液力偶合器的工作原理；煤的水分對碎破過程中的影響；煤的粒度對破碎效果的影響；破碎機械的維修。
 

關鍵詞： 破碎機 ；錐齒輪；液力偶合器 

ABSTRACT
With the development trend of Chinese coal and metal mine towards the upsizing, the half continuous mining technology featuring a large-scale crushing station as the key equipment has been used widely. Considering the main machine of the large-scale crushing station always depend on products from the developed countries such as European counties and USA, it is imperative to develop a new high-efficiency and energy saving crushing equipment to substitute imported equipment and meet the needs for the domestic large-scale mine.
 China's large-scale opencast mine may shift crusher station began in the 1990s. Broken only meet its performance than the soft coal and stripping of the broken, use was limited, can not meet the requirements of the use of mines. This thesis research and the efficient hammer crusher because of its unique structure on the merits, making production capacity, high hardness broken, broken than large, uniform size markers, too small to smash. Thus, the crusher is a broad future development of efficient broken equipment.
The layout having accomplished the complete machine external form putting the dyadic spirit face hammer crusher together designs the main body of a book, application and operating principle having introduced the type crusher of all kinds's, at present domestic crusher current situation and developing trend and, adopt the one-level cone tooth to reduce the speed combining with the broken ability and request; Condition having set forth a gear wheel becoming invalid; Hydraulic coincidence the implement operating principle; The coal moisture content breaks effect in process to being broken; Impact of the coal size over broken effect; Break the machinery be maintained to pieces.
