WARM-FORM GEAR CUTTER ON THE BASIS OF THE INVOLUTE WORM FOR CUTTING SPUR WHEELS

摘要

FIELD: cutting tools. ^ SUBSTANCE: cutter contains the teeth with two lateral and one apical cutting edges located in the plane of the front surface of the tooth; to reduce the labor intensity of production the lateral cutting edges are made in the shape of arcs of the circular located to the effect that for each arc of the circular the value of the arithmetic average distance from its spots to the intersection line of the correspondent lateral side of the involute worm with the plane of the front surface of the tooth passing through the spot of intersection of the arc of the circular and the pitch cylinder has the minimal value. ^ EFFECT: enhanced cutting efficiency. ^ 1 dwg, 1 dwg
