What is a worm and wheel gear?
it is used to change directions
Is worm and wheel reversible?
yes you can reverse worm and gear. A worm gear can rotate the worm, its based on the lead angle, pressure angle and co.efficient of friction between the pairs.
What is the difference of a crown gear or a worm gear?
A crown gear has teeth that engage with other bevel gears. The teeth stick out at right angles to the face of the wheel. A worm gear is a screw that attaches to a wheel by engaging teeth along the wheel. As the screw turns, the wheel also moves and the drive reduces rotational speed and allows for higher torque. Worm gears are used when a project requires large gear reductions.
'What kind of gears would you find in a windscreen wiper and a windmill 'for example worm gear rack and pinion'?
A worm gear can be found in a windscreen wiper and a windmill. It is a mechanical arrangement has a toothed wheel that is worked by a short revolving cylinder or worm that bears a screw thread.
What could a worm and wheel be used for?
gear box or speed reducer.
What is difference between bevel gear and worm wheel?
A bevel gear is cone shaped with the gear teeth placed vertically along the periphery. A worm gear is barrel shaped with the teeth spiraling along the length like a screw.
Why does an electric knife have a nylon gear and a steel worm?
The general answer applies to this and other equipment or tools with similar drives. It goes like this. The worm gear is often machined onto the end of the rotor in the motor. The gear it drives, the worm wheel, is made of material that is not as hard and can fail more easily. If the tool jams up, it is better in the long run (read easier and cheaper) to replace the worm wheel rather than the worm itself. A similar tool with this drive setup is one of the high end Oster barber clippers.
What type of gear is a combination of a gear combined with threads of a screw?
A worm drive.
If you have a worm gear and a sprocket gear and the worm gear rotates slowly on its shaft how will the sprocket gear turn?
Even slower
What is an example of a gear in the bathroom?
Probably the simplest example in the bathroom would be the gear attached to the faucet handle. It consists of a worm gear which opens and closes a valve, restricting or blocking water flow from the spigot.
Why worm is geared with worm gear Give reasons?
A worm or machine can be geared with worm gear to give it higher torque or to reduce rotational speed in the machine.
What is lead in gear?
linear distance moved by the gear(worm,screw jack) for one rotation of the gear(worm,screw jack)
