1、华东理工大学学士学位论文摘要颚式破碎机俗称颚破,由动颚和静颚两块颚板组成破碎腔,模拟动物的两颚运动而完成物料破碎作业的破碎机。广泛运用于矿山冶炼、建材、公路、铁路、水利和化工等行业中各种矿石与大块物料的破碎。被破碎物料的最高抗压强度为320MPa,颚式破碎机的动颚直接悬挂在偏心轴上。由于动颚是偏心直接带动的,所以活动颚板可以同时做垂直和水平的复杂摆动,颚式破碎机对石块不但能起到压碎和劈碎的作用,还能起到碾碎的作用。随着科技的发展,矿石业的需求也大大增加,各种不同型号的颚式破碎机的设计显得尤为重要。本毕业设计主要是对9501250(进料口尺寸(宽×长))的颚式破碎机进行设计,对破碎
2、机上面的各个零件进行拆分,画出各个零件的零件图,然后画出其装配图。计算并确定了颚式破碎机的主要参数及其主要结构的设计,设计内容主要包括了颚式破碎机的动颚,偏心轴,皮带轮,前墙,侧墙,法兰,端盖,等一些重要部件,另外对颚式破碎机的工作原理及特点和主要部件作了介绍,同时对机器参数(主轴转速,生产能力,破碎力及功率等)作了计算以及对偏心轴作了设计。此外,还简单介绍了破碎的意义和破碎工艺,颚式破碎机的操作及维修等等。关键词:颚式破碎机动颚破碎偏心轴V华东理工大学学士学位论文AbstractJawcrusheriscommonlyknownasthebrokenjaw,bymovingja
