Driven by an electric motor, power is transmitted through the power of a variable speed reducer. The chain drive and the worm drive mechanism transmit power to the working mechanism and feed the grinding disc to achieve continuous feed. Grinding wheel feeder is the key equipment to achieve high efficiency automation of smelting sintering system. It can be used to feed various smelting raw materials and achieve continuous quantitative delivery. According to the design requirements, the design plan was formulated, the structure of the grinding disc feeding mechanism was designed, and the main components of the plate were designed, selected and calculated. The content includes the choice of main motor power, gear reducer, and coupling options, worm gear, bearings, sprocket and worm gear design, verification, lubrication methods and lubricants. The disc feeder is reasonable in structure, low in cost, and easy to install and maintain. It can be widely used in steel, metallurgy, building materials, chemicals, energy and other industries. Key words: disc feeder; reducer; coupling 目 录 TOC \o 1-3 \h \z \u 摘 要 I Abstract II 1 绪论 1 1.1磨盘给料机概论 1 1.2 磨盘给料机的应用 2 1.3 给料机的分类 2 1.3.1振动给料机 2 1.3.2螺旋给料机 3 1.4 磨盘给料机设计参数 4 2 总体方案设计 5 2.1 磨盘给料机工作原理 5 2.2 磨盘给料机工作过程 5 2.3 减速器结构 6 3 磨盘给料机的设计 7 3.1 电动机的选择 7 3.1.1 计算电动机所需功率 7 3.1.2 电动机的选择 8 3.2 驱动装置设计 9 3.2.1 分配传动比 9 3.2.2 驱动装置的运动及动力参数计算 9 3.2.3 选定齿轮类型、精度等级、材料及齿数 11 3.2.4 按齿面接触疲劳强度设计 12 3.2.5 按齿根弯曲强度设计 15 3.2.6 斜齿轮传动几何尺寸的计算 17 3.3 轴的设计计算 18 3.4 键的选择和校核 22
