Changes in Tooth Micro-Geometry

Abstract

This paper discusses methods for optimizing the micro-geometry of the teeth of hypoid and bevel gears to improve their operational characteristics. Due to manufacturing errors and changes caused by operating conditions, the teeth of these gears are often not ideally meshed with theoretical profiles, leading to increased wear and localised contact. One effective solution is the modification of the micro-geometry of the teeth, including changes to the tilt angles, pressure angles, and spiral angles. The studies show that the precise adjustment of parameters such as the distances between the elements of the gear meshing helps to improve load distribution and increase the durability of gears. The results of this work are important for improving the performance and reliability of gear drives in various mechanisms, including automotive transmissions and industrial equipment.
