毕业设计(论文) 题目沥青搅拌机设计专业机械设计制造及其自动化学号学生指导教师答辩日期哈尔滨工业大学哈尔滨工业大学毕业设计(论文) 摘要为了提高产品的加工效率和质量,满足特定的加工要求,本课题设计研究了 LB2000 沥青搅拌机的总体构造,使得该沥青搅拌机在相同的要求下达到更好的使用效果,结构更加简便,使用更加方便。根据加工工艺要求进行设计,采用工序高度集中的原则,确定了搅拌机的整体布局方案,拟定了电机的传动路线,应用最优化方法布置零件、确定传动参数,设计了轴的结构,进行了齿轮、轴承等相关零件的强度校核计算。搅拌机采用微机程控和手动相结合的控制方法,大大提高了工作效率和安全,较好实现了设计要求。本沥青搅拌机具有优良的搅拌性能卓越的经济性能优秀的质量和稳定可靠的特性,模块化设计,运输安装快速:模块化和快速安装系统技术的采用,令运输与安装变的更加快捷。现在沥青搅拌机已经克服了无法加粉料和沥青老化的问题,同时由于具有生产设备简单,能力大;但是其仍然具有一些难于克服的缺点,主要有材料无法达到强制搅拌站的精确程度;精度误差比较大;对原料的含尘、水、超限料尺寸要求比较严格。关键词:沥青搅拌机;沥青混凝土搅拌设备;搅拌机;路面机械。 2 哈尔滨工业大学毕业设计(论文) The design of LB2000 pitch mixer Abstract: Inorder toimprove the processing efficiency and quality ofthe products ,satisfied the specific processing demand, this subject designs the overall structure ofstudying LB2000 pitch mixer, make this pitch mixer reach better result ofuse under the same demand .The structure ismore simple and more convenient,and more convenient touse. Design according tothe process, The principle with highly centralized process isadopted inthe design. The whole overall arrangement scheme ofthe mixer isconfirmed. The transmission route ofthe electrical machinery isdesigned, use optimize the method and assign the part isoptimized. The parameter ofthe transmission is decided, the structure ofthe axle isdesigned ,the intensity of carrying onsuch relevant parts asgear wheel ,bearing ,etc. ischecked and calculated. The mixer adopts the programmable controlled and manual control method bine together according puter, which improved the working efficiency security greatly ,and realizes the designing requirement better. This asphalt mixer has fine stirs the performance remarkable economical performance outstanding quality and the stable reliable characteristic, the modular design, the transportation installment fast: The modulation and fast installs the system technology the use, mand transports and the installment changes even more quickly. Now the asphalt mixer already overcame has been unable the question which added the pow
