Abstract: Non-circular gears appeared as early as the 14th century and have a history of more than 700 years. However, the research of non-circular gears is not as long as its history. Due to the special geometry of non-circular gears and the restriction of the design, analysis, manufacture and testing technology in the past, non-circular gears have not been widely used. Nowadays, with the development of computer technology, non-circular gears have again attracted the researchers' attention. In many studies, non-circular gears have applied to more and more application areas. In order to inspire researchers in this field and expand the application field of non-circular gears, the background and development of non-circular gears (mainly cylindrical gears) in the four main research fields:design and analysis, manufacture, testing and application have been summarized and analyzed. Then, the advantages and disadvantages of various theories and methods in the above research fields have been summarized, as well as the problems faced and the possible future development directions.

Key words: non-circular gear, design and analysis, manufacturing, testing, application
