Control Operation and Analysis of the Spur Gears Profile

Abstract

The theoretic profile of cylindrical gear can be described with an involute curve detected in the front section. The correct formation of the profile assures uniform transmission of the angular velocity from the conducting wheel to the driven one. Profile errors result non-uniform gait, noise and pulsation in the teeth and in bearings. The aim of this paper is the determination of the profile errors using the theoretical profile as reference. The experiment was carried out using a coordinate measuring machine. The real profile is constructed by theoretical equations. The errors are determined comparing these two sets of surfaces, the theoretical and the measured profile. These errors are presented in a graphical user interface (GUI) made by the authors. This GUI is parameterized, so it can be used to evaluate any gear.
