Gear Ratios?

Question

Ok, so if i made a vehicle with high gear ratios, say, 1:5:10, would that be less powerful than a vehicle with the ratios from 1:2 or even 1:5? Why?

Answer 1

Techincally, power is independent of gear ratios. The higher the number of the motor turns to one turn of the gear, the higher the torque transmitted down the gear train. But since power is rate of work, that only depends on the motor and not on the gear ratio.

Answer 2

you need to tell us what you mean by "powerful". Faster acceleration, or able to pull a larger load, or better top speed? they are all different and require different gear ratios.

As the other answer said, gears do not change the power, they change the torque.

Answer 3

Powerful means more faster? more torque carrying capacity?

Answer 4

Gears multiply, (or divide), torque, not power.

You choose the gear ratio to use all the torque

your motor can provide at the speed in question.

The fastest vehicle with a given motor will use all

the torque delivered by the motor to drive the vehicle

at it's top speed.

Since this means there will be less torque available

for accelleration at low speeds, that vehicle will suffer

in accelleration.

Thats why we have gearboxes. ....Get it?

Answer 5

turns of the motor   :    to turns of the gear

more motor turns with less  final gear turns is the most powerful
