What is a gear
- Nov 20, 2018 -

The gear is a mechanical component that has teeth on the rim that can continuously mesh to transmit motion and power. It is a toothed mechanical part that can mesh with each other. The diameter of the large gear is twice the diameter of the pinion.


The application of gears in transmissions has long appeared. In the 300 years of BC, the ancient Greek philosopher Aristotle explained the problem of transmitting rotational motion with bronze or cast iron gears in "Mechanical Problems". At the end of the 19th century, the principle of the incision method and the special machine tools and tools that used this principle to cut the teeth appeared one after another, which made the gear processing have more complete means. With the development of production, the stability of the gear operation was taken seriously.


Gears; mechanical elements on the rim that have teeth that continuously engage to transmit motion and power, are toothed mechanical parts that can mesh with each other. The diameter of the large gear is double the diameter of the pinion. If the big gear does not move, the pinion revolves around the big gear for one week, and the pinion rotates for a few weeks? Conversely, if the pinion does not move, the large gear revolves around the pinion for a week, and the large gear rotates for a few weeks? The large gear does not move, the small gear revolves along the large gear for one week, and the small gear rotates once; when the small gear does not move, the large gear revolves around the pinion for one week, and the large gear rotates for one and a half, that is, one rotation at 240°, and 360° rotation. One and a half weeks, the 480° position is rotated for two weeks, and the 720° position is rotated for three weeks.
