摘要反击式破碎机在诸多行业都有广泛应用,比如、建筑、煤炭、矿山、环保、水利等行业,特别是在水电工程,铁路和高速公路等流动性石料的作业中被广泛使用。它是利用物料进入破碎腔后与高速旋转的板锤撞击破碎进行打碎的机器。破碎机需要处理各种物料,但是不同的物料的特性不同,比如说结构特性和物理特性,这就造成了破碎机种类繁多。68728
反击式破碎机破碎中硬性石灰石等材料,因其具有结构简单,重量轻,造价低廉,运转平稳,高效节能等优点。在第四种传动方案中,采用的是涡轮蜗杆减速器,这种减速器的最大好处是传动比大,零件数目又少,因而结构紧凑;由于蜗杆齿是逐渐进入啮合及逐渐退出啮合的,同时啮合的齿对较多,故冲击载荷较小,传动平稳,噪声低。但这种传动的最大缺点是在啮合处有相对滑动,当滑动速度很大,工作条件不够良好时,会产生较严重的摩擦与磨损,从而引起过分发热,使润滑情况恶化,因此摩擦损失较大,效率低。同时也无过载保护。

Abstract The impactcrusher hammer crusher is developed on the basis of, a lot of application in limestone, sandstone, the cement clinker, burned clay, gypsum and coal, ore of broken use, so, it is designed to have a wide range of prospects and rich experience for reference. The essence of the design is, in the final design scheme of the overall, when you refer to all the main parts design, installation, orientation, and the inpidual parts strength check and test. And in the related project, to the impactcrusher rotor hammer live longer carry out more detailed analysis. In all parts of the design, to include the material choice, the size of the sure, processing requirements, the structure of the technology to meet, and other components of the cooperation of requirements, etc. In the strength of checking is, to use the related formula, the analysis of the dangerous parts, check a watch, mapping and calculation, etc. And then on the overall for installation, working process and work all the way to check, and pay attention to the maintenance, insurance device, and other aspects of the problem, the last of the main parts of the machining accuracy, tolerance, the choice of analysis, in order to ensure that the crusher of the final design of economy and reliability.
