What is the gear?
The gear wheel is one with teeth or notches machined into its perimeter. The gear wheel is able to connect with the teeth of the next gearbox to create a basic machine. The transmissions, watches and many other types of machines that work with the help of gears and mechanical assemblies of power units use general wheels. This ability to change is known as a gear ratio. The ratio defines the amount of mechanical power or multiplication created by two gears. The ratio is derived from the gears on each gear wheel. When discussing the transmission ratios for automotive drive drives, if the driving shaft turns the pastor gearing four complete revolutions and circular gears turns the tire of 10 complete revolutions, it is reported to have a gear ratio 4:10. The strength of one person can be increased to the strength of hundreds of hundreds with the correct gear ratio of the gear wheel. Gear wheelIt allows machines to perform and perform tasks that would not be possible with the unique power of people or even horses.
The gear wheel also allows the machine to create high -speed low -speed input functions by multiplying the transmission ratio. By selecting the correct size of the gears, the slow input speed can be converted to a high output speed and the user can enjoy the advantages of a powerful fan by very slowly crank on the handle.
car transmission is the main example of multiplication of equipment. As the car works, the engine remains at a relatively common level of revolution per minute (RPM). To increase the speed, the transmission wheel, the gear combination begins to change or shifts the gear and increases the vehicle's speed. The transmission continues to change the order in which the different sets of the gearbox combinations are connected and the vehicle moves through all possible transmissions to make withE reached the speed of cruise.
The correct transmission ratio in transmission allows the vehicle to work at the speed of the motorway while at a very low engine speed. This is responsible for obtaining an adequate mileage and maintaining the durability of the engine.
