河南农业大学 本科生毕业论文（设计） 题 目 摘 要 he Washing Machine Parts on The Shell Design Abstract The Project is the washing machine parts on the shell design. First of all, the initial overall program washing machine, washing machine and then an analysis of the transportation system and to determine the design of principles; and then in accordance with this principle in accordance with the size of an initial design, the first of the chain conveyor system and its corresponding chain round for the design and to determine the number of chain links and support the delivery of its specific size board. Choice on the basis of the motor to determine the conditions of the motor according to known reducer selected and completed the design of dynamic systems. Then the shell of the washing machine and sink has been designed, the last of the washing machine and drying system, spray system has been designed. Finally, to determine the total washing machine assembly drawing. In the design, based on my own to strengthen and consolidate the specialized course of study, to improve m access to documents and the use of computer graphics capabilities. Key words: shell parts, conveyor systems, power systems, sprinkler systems, drying systems 目 录 1.引言 1 2. 设计的主体内容 1 2.1 初定清洗机的总体方案 1 2.2 输送系统的设计 1 2.2.1 输送系统草图 2 2.2.2 选择输送链 2 2.2.3 确定输送链轮的尺寸 3 2.2.4张紧轮尺寸的确定 4 2.2.5 估算输送链条节数Lp 5 2.2.6 输送板的设计 5 2.2.7 导轨的设计 6 2.3 输送链动力系统设计 6 2.3.1电动机的选择 6 2.3.2分配传动比 8 2.3.3设计链传动 8 2.3.4主动轮设计 10 2.3.5从动轮设计 11 2.4轴的设计及其强度校核 12 2.4.1 轴的设计 12 2.4.2 轴承的选用 14 2.4.3 轴承座的选用 15 2.4.4 主动轴的强度校核 15 2.4.4 键的选取及其强度校核 17 2.5喷淋系统的设计 18 2.5.1喷嘴的设计 18 2.5.2离心泵的选取 19 2.5.3输液管道的设计 20 2.6吹干系统的设计 21 2.6.1喷嘴的设计 21 2.6.2 输气管道的设计 21 2.7 清洗机箱体的设计 22 2.7.1 清洗、吹干室的设计 22 2.7.2 机座的设计 22 2.7.3 水槽的设计 23 2.8 清洗机的总装图 23 2.9 一些说明 24 3. 结语 24 参考文献 25 致 谢 26 1.引言 随着机械行业的发展，对机械加工效率也提出了更高的要求，加工过程中零件的清洗效率也有待提高。金属零件通常是用钢、铁、铝等材料制成，它们在机械加加工过程中要使用各种切削油、润滑油和防锈油，这些油类的主要成分是矿物油或动植物油。这些附着在零件表面的油在进行下一步加工前，大多被要求除去，而人工清洗去除效率很低，零件清洗机应运而生。 本课题主要研究壳体零件清洗机的设计过程，以清洗拖拉机后桥壳
