壳体零件自动清洗机设计.doc

河南农业大学 本科生毕业论文（设计） 题 目 壳体零件自动清洗机设计 摘 要 本设计是关于壳体零件清洗机的设计。首先初定了清洗机的总体方案，接着分析了清洗机的输送系统并确定了设计原则；然后根据这一原则按照初定的尺寸进行设计，首先对输送系统的输送链和与其相对应的链轮进行了设计并确定了输送链链节数及与其配套的输送板的具体尺寸。在此基础上选择电动机，确定电动机后根据已知条件选取了减速器并完成动力系统的设计。接着对清洗机壳体和水槽进行了设计，最后对清洗机的喷淋系统和吹干系统进行了设计。最终确定清洗机的总装配图。在设计的基础上，加强自己对专业课的学习和巩固，提高自己查阅文献和利用计算机绘图的能力。 关键词：壳体零件，输送系统，动力系统，喷淋系统，吹干系统 The 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
