What is the ratio of driven gear to driving?

What is the ratio of driven gear to driving?

Using the colon notation, the gear ratio is 3:1. The order of the two numbers in a ratio is very important. In this case, the ratio of the 15-tooth driver gear and the 45-tooth driven gear is 3:1. A gear ratio is always given as the ratio of the rotations of the driver gear to the rotations of the driven gear.

Is a higher final drive ratio better?

High Final Drive Ratios A higher final drive ratio will result in more torque at the wheels but a lower top speed. Since torque is what helps the vehicle accelerate, a higher final drive ratio will offer better acceleration.

What is a typical final drive ratio?

The pinion gets the drive from the engine while the crown-wheel is attached to the wheels and rotates them. Usually, there are 3 to 4 times more teeth on the ring gear than the pinion. Thus, it provides the final speed reduction between 3:1 to 4:1. The drive pinion is an integral part of the pinion shaft.

What does a 4 1 gear ratio mean?

There is a trade-off between speed and torque, which is rotational power. When the gear ratio is 1:1, the amount of torque is the same, and the speed is the same. If you reversed the ratio (say, 4:1), you would cut the speed but boost the torque.

How is RC gear ratio calculated?

For every mating pair of gears in an RC car, there exists a gear ratio. The gear ratio is simply the number of teeth of one gear divided by the number of teeth of a mating gear.

What is the gear ratio when the transmission is in 1 1 ratio?

In 4th gear, the gear ratio of 1:1 means that the engine and the transmission’s output rotate at the same speed, referred to as the “direct drive” ratio. 5th and 6th gears are known as overdrive gears, in which the output of the transmission is revolving faster than the engine’s output.

What’s the fastest RC motor?

“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds. Not only is this car stylish, but it also reaches speeds over 100 miles per hour.”
