Special Issue Information
Dear Colleagues,
Gears are unquestionably crucial parts in a mechanical system, responsible for transmitting torque in various applications, and in equally varying characteristic length scales, such as car and truck engines, wind turbines, lawn mowers, and watches. Without a reliable- and fully-functioning gearbox, or as in the case of an old reputable bicycle—just a single gear, it does not matter how powerful engine is set to drive the vehicle. For wind power, the gearbox ensures the rotational energy of the turbine generated by the wind is transmitted to the electrical generator.
A well-functioning gear is directly dependent on the quality of its lubrication, and its lifetime is dependent on the friction- and wear dynamics in the system. To be able to optimize the performance of a gear and its lifetime, an understanding of the tribological mechanisms in the system is vital. This is not a simple task; great advancements have been made the last few decades due to the increased computational capacity enabling more sophisticated numerical simulations and refined experimental and evaluation techniques. However, due to the inherent multidisciplinarity of tribology in general, with intersecting areas such as rheology, fluid and solid mechanics, contact mechanics, material sciences, and chemistry, the complexity of lubrication, friction and wear dynamics in gears is highly prominent. We still have a great deal to discover in this intriguing area of engineering sciences.
The current Special Issue is devoted to the latest developments and findings in the versatile area of gear tribology. This Special Issue cover both the functionality of gears by means of the tribology aspects, and the modelling of issues related to gear performance such as lubrication and wear.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Lubricants is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
