ABSTRACT:
A technique for correcting backlash in gears utilized in printing machines. The backlash is corrected by means of toothed segments, i.e. sections of a gear, with each segment having gear teeth of varying width, with the teeth at the center of the segment having greatest width and the width of successive teeth decreasing by 0.005 to 0.6 mm to minimum values at both ends of the segment. Each segment is positioned so that the gear teeth of proper diameter to reduce backlash are disposed next to the teeth of the gear on which the segment is mounted.
