Bevel gears are useful when the direction of a shaft's rotation needs to be changed. They are cone-shaped and usually mounted on shafts that are 90 degrees apart, but they can be designed to work at other angles as well. The teeth on bevel gears can be straight, spiral or hypoid. Str...

Gears carry the motion from the motor to the screwdriver bit. On the next page, we'll take a look at how the gears fit together. Electric Motor The electric motor ©2007 HowStuffWorks The electric motor is a standard DC electric motor. See How Electric Motors Work to see the par...
Gear ratios are fundamental in understanding how gears work, with the ratio indicating how many times a gear has to turn for another gear to turn once; for instance, in a worm gear, a threaded shaft engaging the teeth on a gear can create a high gear ratio in a compact space. Planetary...

A gearset is a set of gears that enable a rider to move from a complete stop to a cruising speed. Transmissions on motorcycles typically have four to six gears, although small bikes may have as few as two. The gears are engaged by shifting a lever, which moves shifting forks inside the...
Upshift back to 2, and if it’s still too easy, then upshift to 3. This works because the higher gears move you farther for each spin of the pedals, making you do more “work”, and making it less “easy”. Did you know REI & REI Co-op have a Bike Sale and Clearance? Click ...
If you were to take the outer casing off, you would see a mass of gears, cams, cranks and belts, all driven by a single electric motor. The exact configuration of these elements varies a good deal with the different sewing machine brands, but they all work on a similar idea. The ...
An easy-to-understand explanation of how gears work and why they can give a machine more speed or force (but not both at the same time).
to judge anyone or to push patients to change before they’re ready. If people are happy with their lives, God bless them. But Roxie wasn’t. Still, we had to tread gently. Long ago, I learned to work with where a patient is at, then go from there. Roxie wasn’t yet ready to ...
