Background

As early as 350 b.c., gears were documented in the literature by the ancient greek famous philosopher, arizusdord. Around 250 b.c., a winding machine using a worm gear was described in the literature by archimedes, a mathematician. The gears in the metric front are also preserved in the irack katesfin vestige today.

The history of the gear is long in China. According to historical records, gears are used in ancient China which is 400-200 years before the Gongyuan, bronze gears which are unearthed in Shanxi of China are the oldest gears found so far, and a compass vehicle which reflects the achievement of ancient science and technology is a mechanical device with a gear mechanism as a core. In the period of the reviving of Italian literature in the latter half of the 15 th century, the famous talent has more than one nano-da vinci, which not only leaves the work and performance of non-wear-out in the aspect of cultural art and gear technology history, but also keeps the prototype of the sketch at that time after more than 500 years. Until the end of the 17 th century, the study of wheel tooth shapes that correctly transmit motion was not initiated. In the 18 th century, after the european industrial revolution, the gear transmission has been increasingly widely used; the development of cycloidal gears followed by involute gears has been the dominant practice until the beginning of the 20 th century. Thereafter, modified gears, circular gears, bevel gears, helical gears, and the like have been developed.

Modern gear technology has reached: the gear module is 0.004-100 mm; the diameter of the gear is 1 mm-150 m; the transmission power can reach hundreds of thousands of kilowatts; the rotating speed can reach one hundred thousand revolutions per minute; the highest peripheral speed amounts to 300 m/s.
