Abstract

669,737. Lapping gears. FELLOWS GEAR SHAPER CO. July 26, 1948 [Aug. 15, 1947], No. 19950-148. Drawings to Specification. Class 60. [Also in Group XXII] A method of finishing a gear wherein a gearlike tool is displaced relatively to the gear along a rectilinear path inclined to both the axis of the gear and of the tool comprises the following features : (a) the rate of feed is 0.011 to 0.035 inches per gear revolution in the direction of the work axis, (b) the crossed axis angle and the angle between the rectilinear path and the gear axis are such that the relative displacement of the gear or tool along said path is at least equal to one fifth of the total relative displacement of the tool or gear when such displacement is sufficient to produce backlash, and (c) the tangent of the crossed axis angle is at least equal to one fourth of the tangent of the angle between the rectilinear path and the gear axis. The latter angle, is not greater than 35 degrees, and the crossed axis angle is not greater than 15 degrees. Preferably the latter angles are 25 and 7 degrees respectively, and the rate of feed is 0.016 inches per gear revolution. The tool may be a shaving cutter, a burnishing tool or a lap.
