Gearboxes 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 or higher rate than the input shaft, and this speed reduction produces a mechanical advantage, increasing torque.
- The gearbox is composed of the clutch shaft, countershaft, main shaft, bearing, and gears
- The clutch shaft utilizes engine force and transmits it to the other parts of the gear, it is linked through a clutch that rotates the driving shaft. It is provided with a single gear fixed on it and rotates with the engine speed together with the crankshaft
- The countershaft is provided with several gears in different sizes that can generate a huge torque level.
- The main shaft is also commonly known as the output shaft, that rotates at a different speed and gives a mandatory torque
- Bearings are mounted on both ends of the shaft which promotes support and helps to deliver maximum power with less friction loss. Gear is used to transmit power from one shaft to another
