Which type of belt transmission is the most widely used in general mechanical transmission

In general mechanical transmission, the most widely used belt transmission is the ordinary V-belt transmission.

Mechanical transmission is widely used in mechanical engineering, mainly refers to the transmission of power and motion through mechanical means. There are two types of friction drives: friction drives that transmit power through friction between components, and meshing drives that transmit power or motion through the engagement of the driving and driven components or through the engagement of intermediate pieces.

Mechanical transmission mechanisms can change the mode, direction, or speed of motion provided by power and be purposefully utilized by people. In ancient China, there were many types of transmission mechanisms that were widely used. In addition to the ones described above, such as seismographs, blowers, and so on, they were all products of mechanical transmission mechanisms. In ancient China, transmission mechanisms mainly included gear transmission, rope transmission, and chain transmission.

Gear transmission. Its emergence was no later than the Western Han Dynasty, when the Guide Car, Jili Drum Car, and the hydraulic astronomical instrument invented by Zhang Heng in the Eastern Han Dynasty used quite complex gear transmission systems. These gears are only used to transmit motion and do not require high strength. As for the gears used in production, they need to transmit a large amount of power, generally with a large stress and high strength requirements.

In ancient times, such gears were used in water extraction, grain processing, and other work using animal power, water power, and wind power. For example, on a rollover, it is necessary to apply a primary gear transmission mechanism to change the direction and transmission of motion to meet the working requirements of the rollover.

Chain drive. "It appeared very early in ancient China, and there were already bronze chains on horses in the Shang Dynasty. Other bronze and jade articles also used chains as decorations.". The bronze chariots of the Qin Dynasty unearthed in Xi'an have very exquisite metal chains. But none of this is considered a chain drive. As a power transmission chain, it appeared in the Eastern Han Dynasty.
