Paper Title:
Application Research of NC Machining of Circular-Arc Aligned Gear
  Abstract

Abstract: numerical control system is used to control the gear hob and gear blank in autorotation and linkage generative movement, to realize the machining of teeth shape and teeth dividing; and at the same time it controls the vertical displacement of the gear hob and the horizontal displacement of gear blank, to make a circular arc track whose radius is the sum of gear blank’s radius and gear hob’s radius, thus realizing the NC machining of circular-arc aligned gear. Before and after the machining of teeth form, transition arc is used to finish the trimming and thinning of the teeth thickness at the teeth end; on the prerequisite of machining the circular-arc aligned gear, this method successfully solves the puzzle of gear chamfering, and discharges all gear burr into the lower end of the teeth. The advantage of this machining method lies in that when the hob cuts deeper, as the both side-blades are cutting the work-piece at the same time, the thinning on both sides are quite symmetrical, and the fine symmetry remains during the uniform change of the teeth thickness. So, the machining precision of the parts is prior to the requirements in the drawing, and this method yields good effect, which broadens the application of NC technology.
