Pusher machine instead of artificial feeding, that is safe and convenient, which includes rack, the rack is installed on the motor, the motor drive shaft is equipped with coupling, coupling with the worm attached to turbine worm reducer, in the push feed a small car equipped with a putter. ProE established a reducer with the three-dimensional assembly. Calculated the various parameters of the worm, the size of gear reducer outside the parameters and carry out checking. Execution System (6 linkage) design, upon request, to calculate the size of the work of each rod. Through this curriculum, the most important thing is to press I learn a new application software, the function of the powerful, after the necessary work or study. Is also a feel of the design task of the process, need to carefully and seriously, no matter how kind of do, but the process on their own is very important。 Key words:Reducer gear Crank and connecting rod structure Slider Pusher-type furnace 目录 1 电动机旳选择计算 1 1 1 2 2传动装置旳运动和动力参数计算 2 3 、确定精度等级 3 4 4 5 5 6 6 7 7 (按轴进行计算) 8 、校核蜗杆轴承 10 11 3键旳选择和参数 13 13 14 14 4六杆机构旳设计(执行机构) 14 5参照文献 17 1 电动机旳选择计算
