Plastic gears: State-of-the-art design and technology (review)
A review of the retrospective and modern state in the field of theory and practice of plastic gears is presented. Various aspects of such gears design, technology and applications are discussed. It is noted that corresponding problems are under considerationpermanently on the last common engineering meetings and specialized ones. The analysis of the papers allows to conclude that main trends in plastic gears are the following once: comparison the experimental results with VDI 2736 and JIS 1759 normative paper data; development of the methods of accelerated tests; investigation on fatigue bending strength, pitting and wear resistance; improvement of the noise, vibration and harshness behaviors; analysis and optimization of reinforced composite materials structure; application of additive technologies; fabrication of high precise plastic gears and development of computer-aided design methodology.
