Introduction of Gearbox:
 

  • Gearbox is an assembly of parts including the speed-changing gears and the propeller shaft by which the power is transmitted from an engine to a live axle.
  • It uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.
  • Gearbox includes the right-angle drives and other gearing in windmills, horse-powered devices, and steam engines, in support of pumping, milling, and hoisting.
  • Most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft (e.g. a motor crankshaft). This means that the output shaft of a gearbox rotates at a slower rate than the input shaft, and this reduction in speed produces a mechanical advantage, increasing torque. A gearbox can be set up to do the opposite and provide an increase in shaft speed with a reduction of torque. Some of the simplest gearboxes merely change the physical direction of power transmission.
