The function of gears.
Author:
Gears are toothed mechanical components that can mesh with each other, and their application in mechanical transmission and the entire mechanical field is extremely widespread. Modern gear technology has reached: gear module from 0.004 to 100 millimeters; gear diameter from 1 millimeter to 150 meters; power transmission can reach over 100,000 kilowatts; rotational speed can reach hundreds of thousands of revolutions per minute; and the highest circumferential speed can reach 300 meters per second. With the development of production, the smooth operation of gears has received attention. In 1674, Danish astronomer Romer first proposed using an epicycloid as the tooth profile curve to achieve smooth-running gears.
