Gear Box

 

a gear-ratio mechanism for step-changing the frequency (speed) of rotation of a driven shaft in relation to a driving shaft operating at a constant rotation frequency. The gearbox consists of sliding gear drives located in a separate housing or in a common housing with the other mechanisms. Another term for the mechanism that feeds into the driving wheels of an automobile and other transport vehicles is “transmission.”
