Abstract
In connection with the improvement of vehicles, power plants, an increase in their power, operational life, requirements for reliability and safety of use necessitate the development of new modifications of the main components and assemblies, incl. drive shafts. In this paper, an analysis of the main types of wear of cardan gears operating in various conditions is carried out. It is shown that the main types of wear of universal joints are: fatigue and abrasive wear, false brinelling, pitting, fretting. To reduce the effect of these types of wear, a comprehensive approach has been proposed, which consists in the development of highly effective methods for hardening the working surfaces of parts, the creation of thin-film composite coatings for friction parts, the development of new compositions of new generation lubricants based on mineral and synthetic oils.
