Abstract
PURPOSE:To eliminate a slack between a rack and a sector gear by grinding the tooth surface while swinging the sector gear by means of a copying model sector gear on the same shaft as the sector gear and a model rack engaged with it. CONSTITUTION:A spindle support stand 5 is mounted as capable of sliding in perpendicular to the paper face on a slide base 12 on a bed 3, and a model sector gear 2 is fitted to one end of a spindle shaft 4 swung by means of a york 7 driven by a motor 6, and it is engaged with a model rack 1 on a rack fixing head 11. A grindstone 9, which is driven in rotation by a motor against a sector gear 8 under process fixed to other end of the spindle shaft, is moved back and forth along a slide 19. During the processing, a locating member 21 takes shelter downward. When the spindle shaft 4 swings, the spindle shaft support stand 5 slides in perpendicular to the paper face and the tooth surface is grinded.
