Gears play an important role in trucks, car, buses, motor bikes and even geared cycles. These gears control speed and include gears like ring and pinion, spiral gear, hypoid gear, hydraulic gears, reduction gearbox. Automotive gear ratio is the number of turns of the drive wheels in relation to the number of turns of the engine. If the engine is considered the input and the drive wheel is considered to be the output then the input gear or the pinion is said to mate with the output gear or the ring gear to drive or rotate it.
Depending on the size of the vehicle, the size of the gears also varies. There are low gears covering a shorter distance and are useful when speed is low. There are high gears also with larger number of teeth. These high gears cover a longer distance with one revolution of pedal.
Angular Bevel Gears :
Used in rotor craft drive system to redirect the shaft from horizontal gas turbine engine to the vertical rotor.
Bevel Gears : Important components on all rotorcraft drive system.
Crown Wheel and Pinion : Used in motorcycle automotive gearboxes.
Differential Gear : Helps two wheels of the car to rotate differentially with respect to each other.
Fine Pitch Gear : It is an anti-backlash gear used to minimize errors introduced by backlash.
Helical Bevel Gears : Used as storage and retrieval units in automobiles.
Helical Gears : In helical gear the teeth are cut an angel, allowing for more gradual and smoother meshing between gear wheels.
