Analitical Method to Calculate the Unknown Geometry of Cylindrical Gears

Gonzalo González Rey, Alejandra García Toll

Abstract


A mathematical method of reverse engineering to determine the basic geometry for manufacturing of external parallel-axis cylindrical involute gears by means of workshop measurement tools is presented. This procedure proposes a practical method to obtain the fundamental gear parameters in order to have a reference for calculating the load capacity of cylindrical gears or when a “copy” of an external parallel-axis cylindrical involute gear is necessary for recreating other new gear according to ISO standards by generation cutting.
