A gear is made up of toothed wheels ("teeth") connected to shafts. To calculate speed ratio, otherwise known as gear ratio, you divide the number of teeth of the input gear by the number of teeth of the output gear. Speed Ratio Definition A gear train consists of more than one gear ...
calculate the gear ratio as 40/20, which simplifies to 2/1, or 2:1. (The tooth count on the driven wheel always goes on top of the fraction or first in the ratio). This tells you that, for every rotation of the driven wheel, the driver wheel makes two rotations. Similarly, a rat...
How to calculate if a gear purchase has paid itself off Dec 11, 2020 Hello everybody, I'm trying to be a bit more thoughtful when making a gear purchase (who doesn't want to buy more lenses! haha). I was wondering if you had any tips on what % to use to calculate if a gea...

Gears are generally used for one of four different reasons: To reverse the direction of rotation To increase or decrease the speed of rotation To move rotational motion to a different axis To keep the rotation of two axes synchronized Understanding the Concept of the Gear Ratio Understanding the...

The amount of drag is proportional to the airspeed of the hang glider: The faster the glider moves, the more drag it creates (see How Gliders Work for details). How a pilot maneuvers a hang glider As with soarplane gliders, the balance of these three forces (lift, drag, gravity) ...

anelectric screwdriverhas a very large gear reduction (reduction in the speed of a rotary machine such as an electric motor) because it needs lots of torque to turn screws. But the motor only produces a small amount of torque at a high speed. With a gear reduction, the output speed can...
