Abstract

823,729. Gear finishing. NATIONAL BROACH & MACHINE CO. Nov. 5, 1956 [Dec. 12, 1955], No. 33666/56. Class 83 (3). In a method of shaving a gear, a cutter having its most nearly aligned cutting edges disposed in helical paths 53 is fed relatively to the gear in a direction parallel to the common normal to their axes, while preventing relative motion between them in any direction transverse to the common normal, and while positively rotating the gear or cutter. The staggering of the edges avoids cutter marks. The cutter has unmodified teeth and is rotated to give a cutting speed of 250 ft./min. while being fed radially of the gear. Just prior to, or upon full depth being reached, the rotation is reversed. A crossed axis angle of 20-30 degrees is used. By providing opposite sides of the cutter teeth with different pressure angles, a correct gear is produced without the necessity of reversing rotation. Reasons are advanced in the Specification as to why the method does not produce an undesirable hollow lead modification, as would be expected theoretically. Moreover, it is stated that gears with a slight crown have been produced by the method. Internal or external gears can be shaved by external or internal cutters.
