Research On Fewer Teeth Gear Hobbing Processing Technology

Y38 hobbling machine bed is widely used in the engineering practice of typical gear processing equipment, due to the gear hobbling machine machining involutes gear has the characteristics of continuous cutting, machining efficiency and precision is higher. If can in Y38 hobbling machine bed processing production directly, for application of few teeth gear will bring great convenience.This paper analyzes the gear hobbling machining process, the size of each cutting edge hob cutter tooth cutting force, cutting force and calculating the total. MATLAB software is used to describe the hobbling process track to hob and gear meshing condition for parameter invariant, when solving the hob cutting in the gear machining section and the cutting track of a cylinder.Study selection using the generating cutting principle in Y38 hobbling machine processing few teeth roll cutting technology, analysis Y38 hobbling machine drive system, realized the few teeth gear in theory in Y38 hobbling machine processing, and cannot be started in the processing of machine tools, workbench, rotational speed in excess of the prescribed limit of rolled low cutting speed for theoretical analysis.On this basis a Y38 gear hobbling machine bed processing few teeth gear modification, using electromagnetic coupling induction motor instead of machine tool main motor, the connection method of gear reducer, achieved in Y38 hobbling machine bed processing and few teeth gear, and summarizes the advantages and disadvantages of solution.
