Title: Improvements in or relating to bevel wheels
IPC: B23F1/06
Filed: 1928-04-12
Abstract: 288,610. Coutant, R. G. L., (Assignee of Veber, G.). April 13, 1927, [Convention date]. Gear-cutting.-In bevel gearing, the tooth profiles are of involute form varying in pressureangle from one end of their length to the other in such manner as to be substantially superposable. Fig. 6 shows, for example, three involute arcs d, d<1>, d<2> of pressure-angles. 22‹, 21‹, and 20‹ respectively and substantially identical over the greatest tooth height h, n. In practice, teeth approximating sufficiently closely to the theoretical form may be produced by the use of a cutter the profile of which corresponds with that of the required tooth form at the largest pitch diameter, the profile of greatest pressure-angle being situated at this point. Preferably, the intermeshing wheels are each formed by moving a rotating milling-cutter x, Figs. 7, 8, with helically arranged teeth extending over a segment A and lateral cutting- faces of the involute form required at the largest pitch diameter, or a reciprocating tool, so that its axis follows a. path parallel to the bottoms y of the tooth spaces, while the bevel blank is rotated on its axis. The completed wheel has non-tapering teeth, the tooth spaces being wider than the thickness of the milling-cutter and the teeth thinner at the pitch circles as they approach the larger ends of the wheels.
