Transient Wear Analysis Model for Cylindrical Gear Conjunctions

Lead Research Organisation: Loughborough University
Department Name: Wolfson Sch of Mech, Elec & Manufac Eng

Abstract

The proposed research aims to develop a novel transient wear analysis tool with particular focus on cylindrical gear pairs. The model will be developed for commonly used materials for this type of gear pairs. The developed methodology will enable the estimation of wear at the design process to maintain a desired level of durability in the final product. The tool will be capable of integration with tribo-dynamic tools to deliver an estimation of NVH refinement and efficiency.

The developed model and knowledge will have a generic form, being able to be implemented in other fields of study with similar underlying physics. They include bearings, piston-ring pack, valvetrain, artificial joints and seals.

Description The investigation has lead to a method that helps to determine how the changes due to wear on the surfaces of contacting gears due to sliding motion impact their efficiency to transmit power as well as the associated noise, vibration and harshness.
Exploitation Route Industry that design gear pairs can use this work to objectively optimise gear pair geometry for multiple objectives: wear, efficiency and Noise Vibration and Harshness refinement.
