1) Speed Reduction of Speed Reducer/ Gear Box
a) Gear Ratio
The gear ratio is a measurement of how different gear sizes interact to transfer energy. The measurement
of a circle, which is a major component of gears, is the most important portion of this computation.
Examining the circumference of a circle might help you understand how to calculate the gear ratio.
b) Driver Gear
The driving gear is the equipment that provides the energy (often called the driver).
The majority of mechanical systems require the use of gears. Gears are wheel-like revolving objects
with teeth around their rims. One gearwheel transfers turning motion and force to the other as the gears
rotate together. In a mechanical system, gears are used to transport energy. Gear trains of two or more
wheels work together to transfer rotary motion and force from one part of a complex machine to another.
c) Driven Gear
The driven gear is the gear to which the force is directed (often called the follower).
Regardless of how many gears are in the series, they are the biggest of the gear set and come
in a variety of designs.
