The graph of angular velocity vs. torque show how angular velocity decreases as torque increases. On the mechanical power vs. torque graph for the 64:1 gear ratio, it is interesting how the efficiency peaks before the mechanical power is nearing its max.

This allowed the mill to grind more corn per hour than most other gristmills, which had a lower gear ratio. Here is a basic relationship for geartrains: Torque. times . Speed = Power. Except for friction losses, power remains a constant in a gear train. In our example above, speed was 15 times smaller on the output shaft, which means torque was ...

At this point, the CVT will hold this gear ratio, and the snowmobile will continue to accelerate through continuing to increase the engine speed. ... This can further be related to a velocity vs. time graph, also produced by the system model, to determine the snowmobiles power vs. velocity.

The closest gear ratio to the ideal value that could be found was the MP Jet 4.1 gear ratio ball bearing gearbox. This gearbox caused the motor to run at a lower voltage than the ideal gear ratio. This decreased our actual maximum speed to 117.7 ft/s.

Gear 1 is the gear with the highest n/v ratio, gear ng is the gear with the lowest ratio. ng determines the number of forward gears. 2.5 ndv i is the ratio obtained by dividing the engine speed n by the vehicle speed v for each gear i , i = 1 to ng , min-1/km/h;

Using our geometry of similar figures, since the ratio of the radii is 1 to 3, the ratio of the arc lengths is also 1 to 3. So B travels 3 times the distance in the same amount of time. Linear Speed is distance traveled divided by time.

The gear ratio is the ratio between what the motor is able to continuously spin on its own compared to the desired operating point speed. As described before, See Section 1.2.3 for information about the motor’s operating point.

On mating gears, when the tooth profiles are designed so as to produce a constant angular velocity ratio, these gears are said to have conjugate action The standard tooth profile that provides conjugate gear action is the involute profile (There are others, but not used often)
