Abstract

1,192,430. Gear-cutting. W. FERD. KLINGELNBERG SOHNE G.m.b.H. 11 Dec., 1967 [25 Feb., 1967], No. 56143/67. Heading B3K. A worm-gear or like hob comprises two body parts joined by an intermediate ring, the teeth of a gear being completely cut by the cutting edges 19, 20 adjacent the gap. As the hob is reduced by sharpening, the ring is reduced in thickness so that the tooth gap at the centre remains the same. The teeth are relieved helically on their front faces when the inter-tooth grooves are helical and are relieved radially on a logarithmic or archimedean spiral. The flank clearance angles may differ and may be up to 8 degrees and the tip clearance angles may be less than 10 degrees. A new hob cuts over-depth in order to permit several resharpenings to take place. For rough-cutting, the ring (16) is selected to cause the edges 21, 22 to take the main cut.
