Abstract

665,947. Gear - finishing. NATIONAL BROACH & MACHINE CO. Oct. 5, 1949 [Jan. 10, 1949], No. 25616/49. Class 83 (iii). A shaving-tool 12 for finishing worm teeth 10 comprises teeth with surfaces intersecting the flanks to form cutting edges, the surfaces being inclined at various angles less than 45 degrees to the axis of the tool, and the said cutting- edges being present on some of the teeth throughout the entire active tooth height of the tool. The tool is of plain or helical spur form. Various arrangements of teeth are shown, such as in Fig. 5, and the ends of the teeth may be chamfered. The inclination of the surfaces is preferably between 2 and 30, degrees. In a modification the surfaces are formed by gashing the teeth as shown in Fig. 8. During finishing the tool is mounted for free rotation and relative traverse is imposed in a direction lying between the lines 16, 18, Fig. 2. The worm may be finished in a plurality of strokes with reversal of rotation and infeed after each stroke. Numerical examples of finishing operations are given, in one of which relative traverse is effected at an angle of 45 degrees to the worm axis at 4.6 inches/min., the worm rotating at 600 r.p.m. and the total infeed being 0.001 inch.
