河南科技学院 200届本科毕业论文（设计） 论文题目：——减速器设计 学生姓名： 所在院系： 机电学院 所学专业： 导师姓名： 完成时间：200年月日 电葫芦中间是钢丝绳卷筒，用小车悬挂于工字钢制作的天车大梁上，一端用法兰固定一台能够制动的锥形转子电动机，用传动轴将动力传递到另一端的减速机。经过减速的动力传递给钢丝绳卷筒，带动吊钩起重。 提升电动机选用葫芦专用锥形转子异步电动机，该种电动机具有通电转动、断电自制动，输出为矩形花键。通过计算选择ZD131-3型号的电动机。 电葫芦减速器采用三级同轴结构，具有布局合理结构紧凑、重量轻、体积小、传动运行平稳等特点。减速器外壳采用优质铸铁材料、轴全部采用优质合金，具有高强度，重量轻的优点。减速器齿轮采用硬齿面斜齿轮的标准设计计算、材料为优质钢或合金钢，能够承受较大的载荷，抗冲击能噪声较小等优点。相关配件及附件如：轴承、通气螺塞、放油螺塞、键、轴承端盖、密封圈等的选择均根据手册计算选用。 关键词：起重设备；电动葫芦；卷筒；三级同轴减速器 全套图纸，加153893706 The design of 1.5t Electric Hoist Abstract Electric wire rope hoist drum is the middle, used car flying in the I-beam girders Crane produced, one end with a flange fixed to the conical rotor brake motors, used to power transmission shaft to the other side of the reducer. After slowing the momentum transfer to the wire rope drum, lifting hook driven by the rope drum. Hoist motor upgrade selection of special cone-shaped rotor induction motor, with the power of the motor rotation, brake when the power off, output is rectangle spline. Choice the ZD131-3 motor models by calculating. Electric hoist reducer coaxial three-stage structure, have a rational layout and compact structure, light weight, small size, stable transmission and so on. Reducer casing use of high-quality cast iron materials, shaft all use of high-quality alloy, with high-strength, light weight advantages. The reducer helical gear using the hardened gear standard design, materials is high-quality steel or alloy steel, to withstand a greater load, shock, noise, etc. Related parts and accessories such as: bearings, ventilation plug, put the oil plug, key, bearing end caps, seals and other options are selected in accordance with the manual calculation.
