Special Issue Information

Dear Colleagues,

The modeling and prediction of wear in gears have been ongoing challenges in the fields of tribology and mechanical engineering. Over the past two decades, significant contributions have been made to understand the complex phenomena associated with gear wear, including contact mechanics, material degradation, lubrication dynamics, and the effects of operational conditions on gear performance.

As gear systems are integral to a wide range of mechanical equipment, from automotive transmissions to industrial machinery, the ability to accurately predict wear and failure is of paramount importance. The interplay between the contact interface, the tribological properties of the materials, and the dynamic loading conditions makes the modeling and prediction of gear wear a multifaceted problem that requires interdisciplinary approaches.

This Special Issue is dedicated to advancing the state of the art in modeling and predicting wear in gears. We invite researchers from around the world to submit their original research articles, review papers, and case studies that address the following topics:

  • Experimental and theoretical studies on gear wear mechanisms;
  • Development and validation of wear prediction models;
  • Influence of lubrication on gear wear;
  • Role of surface roughness and material properties on gear wear performance;
  • Impact of operational conditions (speed, load, temperature) on gear wear;
  • Condition monitoring and diagnostic techniques for gear wear detection;
  • Numerical simulations and multiscale modeling of gear contact and wear;
  • Case studies on gear wear in real-world applications.

We are particularly interested in contributions that integrate knowledge from tribology, materials science, mechanical engineering, and computational mechanics to tackle the challenges in gear wear prediction. By bringing together experts from these fields, we aim to foster a collaborative environment that leads to innovative solutions and improvements in gear design, maintenance, and reliability.

This paper introduces an experimental approach to study the distribution of power losses in an oil jet-lubricated planetary gear set, with the aim of increasing the efficiency of these gearboxes. A thermal model is developed to estimate power losses associated with temperature distribution. This model is applied to analyze experimental data collected from a dedicated test setup. Different configurations are studied to progressively validate the thermal network. In this paper, only a configuration composed of a rotating ring gear and a fixed planet carrier is studied. This configuration enables the validation of a thermal network developed from a basic configuration where power loss sources are not numerous. The study reveals that, for this configuration, load-independent power losses are primarily attributed to hydrodynamic losses in the bearings, while the gear windage effects are of second order. The power losses are then compared to those generated by the same planetary gear set but using a rotating planet carrier. The comparison shows that the configuration composed of the rotating ring gear and fixed planet carrier produces less power loss than the other configuration. Full article
