How is the transmission between the gears calculated?
The five ring of the driving wheel is the 100 gear, that is, a circle of the driven wheel. This is the case of slow drive; in turn, the driving wheel 100 teeth, driven wheel 20 teeth, then the growth rate. The driving ratio is 5; the driving wheel is small; the driven wheel is large; the reduction ratio is 5; on the contrary, the speed ratio is 5;
The rack can be viewed as an infinitely large gear. There is no way to calculate the gear ratio: the rest are the same. There are differences in gear drive (internal gear drive and external gear drive)
Gear drive can play a role in reducing the force, but also can only achieve the purpose of slow down or speed up; the former has a very important strength, reliability and other complex calculations. This is a widely used form of mechanical transmission, is a wide range of applications, a very technical content of a technology.
I describe the following as plain as possible:Transfer movement, with a fixed axis parallel shaft gear transmission is the most simple example: if the driving wheel (engine and motor connected) tooth number is 20, the driving wheel (connected with work machine) tooth number is 100, because the teeth are engaged with each other, so the driving wheel is a circle, from the wheel turned 20 teeth,
