Mechanical transmission is widely used in mechanical engineering, mainly refers to the
transmission of power and motion by mechanical means. It mainly includes gear drive, belt drive, chain
drive, friction drive, hydraulic drive, etc.
Gear transmission is an important basic part of mechanical equipment. Compared with belt chain,
friction and hydraulic transmission, it has a series of characteristics such as large power range, high
transmission efficiency, stable movement, accurate transmission ratio, long service life and compact
structure. It is irreplaceable in the field of general mechanical equipment for the characteristics of
safety, reliability and cost-effectiveness .
