What is the difference between helical gear and screw?

Spur gears have straight teeth while helical gears have curved teeth. Generally, helical gears are usually quieter and smoother in operation, while spur gears are easier to make and much less expensive.Helical gears are stronger than spur gears.


Is there anyway it increase the power out put of a motor?

The power output of a motor can be changed by the use of gears. Gears can be used to increase torque by reducing the speed of the output shaft by placing a large gear on the output shaft, coupled to a smaller gear. Conversely, by using a small gear on the output shaft, coupled to a larger gear, the speed can be increased with a reduction in torque.


Where are worm gears used?

worm gears are used in machines that need high gear ratiosspoonsWorm gears are found in some kinds of 90 degree gearing junctions, generally with a large change in gearing ratio.For example, many tillers have worm gears between the input shaft and the crosswise tines.Since a motorcycle doesn't need a true differential, it may also have a worm gear connecting the drive shaft to the rear wheel.An adjustable end wrench (Crescent Wrench) also has a worm gear for adjustment, and it is easily visible.There are some devices such as a telescope stand that have precision adjustment with a worm gear, especially if the only adjust through a fraction of a circle.Worm gears are used to reduce speed. They can be found in factories. Google it to buy one.
