Modernization of Tooth-Rounding Equipment in Gear Production

Russian Engineering Research Aims and scope

Abstract

For smoother gear changes, the ends of the gear teeth are rounded in gearboxes. The rounding profile depends on the gear’s operating conditions. A cam has been designed for the manufacture of a nonstandard tooth-tip profile (120° facets) on a 5N530 machine tool. The profiling algorithm for the cam is described, and the coordinates of a random point on the cam profile are calculated in several examples. Some relations between the cam geometry and the geometry of the gear being machined are explained. The calculations largely employ MS Excel software, which requires practically no special skills. KOMPAS-3D software is used to formulate the design problem and for the design of the cam profile itself. The method proposed for cam design is simple and readily employed.
