But manufacturing industry productivity? is mainly decided by the manufacture equipment -- engine bed's advanced degree. ?? This design isΦ1500㎜ the gear blank special-purpose lathe to feed speed change system design. The lathe to feed system module by to feed gear box, the apron and so on is composed. According to the project description request, the lathe main axle's rotational speed divides into two areas, high speed area and low speed area. The high speed area rotational speed is situated between 60--160r/min; The low speed area speed is situated between 6--16r/min. From the electrical machinery 1450 r/min rotational speeds, fall to the 6r/min rotational speed, the reduction gear ratio achieve 1:241. To feed quantity range of variation which matches with the main axle is big. This is one of this design difficulties. The designer root uses from the headstock adopts the cutting velocity, through the gear box speed change, to feed quantity which must match with the lathe, thus has solved this problem. ? In line with “economy, practical” the principle of design, this design basis lathe finishing and the roughing various requirement, has designed two kind of different to feed quantities. And selected to various part of designs has carried on the detailed computation and the proof, the organization simplifies, the layout was compact, the frugal material, reduced the cost.
