| In the current market economy,how to complete production tasks with the lowest consumption in the shortest time is the tireless pursuit of people.Therefore,the "economy" and "periodicity" of worm wheel processing are very important.This topic is from dalian heavy industry crane deceleration machine factory.In the actual production process,the factory often receives the production order of the single-piece non-standard worm gear or the worm wheel needed to repair the machine.In the above two cases,the production cost and production time of worm wheel processing are extremely high.In order to adapt to market trends and solve the practical difficulties of factory,this paper puts forward with fly-cutter(no tangential tool post)hobbing worm gear of a kind of method,this method is convenient and feasible in the individual production,in solving the urgent worm gear processing tasks is a very practical and effective method.The research of the subject is based on the detailed theoretical analysis,and puts forward its own opinions in the research methods,research methods and various links in the research process.In the analysis stage of principle,the formation of worm spiral Angle and the relation between worm wheel and fly-cutter,the indirect enveloping principle of worm gear tooth shape,the calculation of the split gear wheel and the concept of "roll cutting ratio" are introduced in detail.In the process implementation,the methods of cutting into the feed,the adjustment of the machine tool,the installation of the tool,the technical inspection of the finished products are all put forward their own opinions;In the tool design,the types and shape of the cutter body are introduced in detail,the choice of cutter cutting parameters is discussed,and the tool interference situation is discussed.Finally,the effects of the parameters on the quality of the parts and the corresponding solutions are presented through machining the finished parts.The practice shows that the worm wheel with fly-cutter can meet the needs of users’ daily use,and also can meet the needs of machine repair work.The use of this method saves enterprises from the cost of cutting the cutting tool and non-standard cutting tools,and also greatly reduces the production cycle of worm gear,which is worth promoting to the whole social enterprise. |
