完整设计论文 摘要 目前我国开采薄煤层的机械设备机较少 而刨煤机是一种价格低、结构简单、维修方便、操作容易的采煤设备。
因此有必要对刨煤机进行研究设计。
本文对刨煤机目前国内、国外的发展情况进行了阐述,主要对刨煤机刨头的传动系统和急停缓冲装置进行了设计研究。
本文选用由由电动机、耦合器、减速器组成的机械驱动装置,由该装置向刨头提供动力;通过对刨头的受力分析,结合刨头实际采煤过程,利用气压传动的原理,对现有的气缸稍微改造来设计一个急停缓冲装置。
刨头传动系统带动刨头完成切削煤壁的运动,急停缓冲装置,保证刨头运行到工作端面时候紧急、可靠、安全地停车。

Therefore it isnecessary to carry on the research to design the coal plow. This article to the coal plow the home the overseas developmentsituation has carried on the elaboration at present mainly and stoppedthe buffer mechanism to the coal plow discount transmission system toconduct the design research anxiously. This article selects by themachinery drive which by the electric motor the coupler the reductiongear is composed provides the power by this equipment to the discountThrough to the discount stress analysis the union discount actual miningcoal process the use pneumatic actuator principle designs one to theexisting air cylinder slightly transformation to stop the buffermechanism anxiously. The discount transmission system impetus discount completes thecutting coal wall the movement stops the buffer mechanism anxiouslyguaranteed the discount moves to work end surface time urgent reliablestops safely.Key word: Coal plow Transmission system Stops the buffer mechanismanxiously前言 .................................................... 51 绪论 .................................................. 61.1 课题来源 ............................................ 61.2 课题的设计目的及意义 ................................. 61.3 刨煤机在国内外的发展情况 ............................. 61.4 制约我国刨煤机发展的主要因素有 ....................... 81.5 对刨煤机行业在国内发展的建议 ......................... 81.6 设计内容和预期结果................................... 92 刨煤机的传动系统设计.................................. 112.1 机头机尾传动系统的布置 .............................. 122.2 链论的选择设计 ...................................... 132.3 传动链保护装置设计 ................................ 142.4 电动机的选型 ........................................ 152.5 联轴器的选型计算 .................................... 162.6 减速器的选型 ........................................ 172.6.1 减速器的选型计算 .................................. 172.6.2 减速器低速轴外伸段直径的计算及校核................. 183 刨头缓冲装置的设计.................................... 203.1缓冲装置的方案..................................... 203.2 刨头刨削阻力的计算 ................................. 213.2.1 刨刀间距 t 的确定 ............................
