Special Issue Information

Dear Colleagues,

In recent years, environmental and sustainability issues have become increasingly important. The dynamics and lubrication of gears are growing concerns for environmental and sustainability issues. The dynamics and lubrication of gears have been important under higher loads, speed, temperature and performance expectations in multiple powertrain applications, including automotive, aeronautical and marine applications. Therefore, recent advances in the dynamics and lubrication of gears will be able to be effectively utilized. This topic is effective for the improvement of the efficiency of machines.

This Special Issue aims to provide a platform for researchers to share their latest findings and applications related to gear technologies, including gear dynamics analysis, tooth contact analysis, vibration control, noise reduction, and lubrication techniques, etc. We welcome original research articles, review papers, and case studies related to these topics. Contributions with real experiments are encouraged.

In the current energy landscape, efficiency is a critical topic. Therefore, even in the case of geared transmissions, it is essential to predict and calculate power losses as accurately as possible from the design phase. There are mainly three categories of losses in a gear unit: friction—the power losses due to the contact between teeth in rotation on the one hand and the seals with the spindles on the other hand; churning—the power losses generated by the air–lubricant mixture compression around teeth roots during rotation; and windage—the power losses due to the teeth aerodynamic trail in the air–lubricant mixture. While the first two categories of losses are intensively studied in the literature, the papers focusing on windage power losses are less representative. An estimation of windage power losses can be performed by numerical simulation, and the accuracy of the results depends on the mesh density and the available computing power. The present study discusses the influence of meshing on the windage torque of an orthogonal face gear immersed in air and compares numerical results generated by SolidWorks 2025 Flow Simulation software with experimental data measured on a test rig.
