Abstract

154,184. Aktiebolaget Svenska Kullagerfabriken. Nov. 19, 1919, [Convention date]. Gear-cutting; milling-cutters.-Spur or bevel wheels with straight or skew teeth are generated on the rolling principle, for example, by pairs 2. 3 of grinders or cutters inclined to each other at twice the pressure angle and moving in on a straight line 6 as the blank 1 rotates, in the case of spur teeth, and swinging about the axis of the generating-cone when the teeth are bevel, the cutters being conically or otherwise concave or convex, as shown at 8, 9, so that the teeth are curved across their breadth, the radius of curvature being less at the top than at the bottom of the teeth, the length of tooth contact thus varying during the drive. The meshing teeth may respectively or both be concave and convex.
