6YL-60型螺旋榨油机设计 摘要 食用油作为人们生活中必不可少的物质资源，它的榨取技术始终是是我国一直以来一项重要的生产技术。从以前的纯手工加工到现代的机械榨油，榨油技术经历了巨大的改进与变革，同时为人们提供更健康方便的生活。其中，螺旋榨油机作为现在生产生活中使用最广泛的榨油机械,它的特点是具有连续化、单机处理量大，通常应用在高油分物料的一次压榨以及预榨工艺中。本次设计的螺旋榨油机主要适用的榨油材料有花生，大豆，葵花籽等材料。 榨油机的种类有很多种，这次设计的主要目标是中小型螺旋榨油机。它的总体结构设计主要包括榨油机构，齿轮传动机构及带传动机构，进料机构及出油装置等的结构设计。这次设计的主要计算包括对电动机输入端和输出端的功率和转速的计算，再根据结果从标准中进行合适的选择；齿轮传动和带传动的设计计算选择并对进行校核，根据校核结果判断设计数据是否成立。若成立，则可取，若不成立，则另选择数据进行计算；轴的设计，榨螺榨笼的设计，轴承、键、联轴器的选择及校核等等也都按上述过程进行。榨油机工作时，主要部件有其中的榨螺和榨笼。而榨螺部分主要包括榨螺轴、榨螺、调饼头、锁紧螺母和调节螺栓等。为了保证榨螺腔装配的严密性，采用锁紧螺母将其端部夹紧，防止油饼渗入榨螺孔内，影响榨螺的顺利安装拆卸。榨膛包括榨条和榨圈两部分，榨条位于前一部分，榨圈在后一部分后部分。对于变速箱的设计，必须注意各相邻部件之间的配合关系是否得当，传动比是否满足传递足够的动力以及扭矩是否能承受正常载荷，以满足正常工作条件等要求。 关键词：榨油机；榨螺；榨笼；榨膛 Abstract Edible oil is a
