What is the device ratio?
The transmission ratio is the relationship between the number of teeth to two gears that are ignited. This relationship is expressed mathematically. For example, if one gears with 13 teeth are powered by gearing with 21 teeth, the transmission ratio is 1/1.62 or 1: 1.62. Almost all types of mechanical machines such as vehicles, agricultural equipment and industrial machines, in some way use gears and gearbox ratios are used to define machine performance.
The idea of the transmission ratio is based on the circuit of the circles. When the two gear is connected to the outer edge of the different circuits, the movement of one is converted to a greater or less movement by another. If the gear with a large circuit rotates, which is only half as large, the smaller gear turns twice as fast as larger. The same concept works in the opposite.
gear ratios are specifically adapted to manMotor and other machines, to achieve a certain result. In some contexts, such as car transmissions, the transmission ratios can be changed to adapt to the needs of the car at different speed speeds. The lowest gear in the car gearbox will have a high gear ratio, such as 2: 1 or 3: 1. This gives the car the ability to easily start moving from a complete stop, such as a traffic light. Since the engine must carry out two or three revolution for each revolution, the engine cannot produce a car in a low gear very quickly.
In the second stage, the gearbox ratio is lower, which means that the engine may not work so hard to provide the car for further acceleration. In higher gears, gears are gradually decreasing. They are good for slight acceleration and reduce the engine speed needed to keep the car at a convenient voyage speed. The gears in the transmission therefore serve to enlarge or reduce the output ofat the speed of the car at the time.
gears can sometimes be connected by belts or other ways, but most of them are joined by teeth. This arrangement provides some clear benefits. First, if none of the teeth breaks, there is no slip between the gears, which would result in a loss of efficiency. They also allow to design accurate gear ratios. Although the circuits of the gears are slightly imperfect, the teeth do it so that these imperfections do not matter. Since they exactly synchronize gears, they also give them an accurate gear ratio.
