Research on the Mechanical Wear of Gear-Shaped Parts

Dear Colleagues,

Gear-shaped parts are widely used in industries for the purpose of sealing, power transmission, etc. They are usually in direct contact with paired gears to perform their functionalities, and surface wear due to the interaction of micro-contact of rough sliding surfaces is one of several failure modes. Apart from the direct material loss that leads to the functional failure, the wear causes the system to change its vibration and noise characteristics and consequently accelerates the occurrence of other failure modes.

At present, contemporary wear theories make it possible to build a relatively accurate model to assess the wear state of a surface, and the wear measurement techniques are capable of displaying the surface topographies at an enlarged scale. However, the in-depth wear mechanism of gear-shaped parts bridging the manufacturing process, molecular details, and macroscale properties of materials remains unclear. A good understanding of the wear mechanism and the monitoring and evaluation method is desired for the strength enhancement of gear-shaped parts and elongation of gear-like systems.

This Topic aims to provide a premier international platform for professionals to discuss and present their most recent research on the mechanical wear of gear-shaped parts. The articles in this Topic will cover various topics, including surface modification, lubrication, and tribology; anti-friction design; wear and wear evaluation; and fault diagnosis or damage detection of gears. Submissions on other topics are also welcomed.
