Hi guys in this article we learn about the topic Difference between Spur Gear and Helical Gear it important topic in Theory of machine so without wasting of time let's see some further information,

Difference between Spur Gear and Helical Gear

Difference between Spur Gear and Helical Gear

Sr.no.	Spur Gear	Helical Gear
1	Spur gears are simplest type of gears and gears are straight cut gears.	Helical gears are cylindrical type of gears and teeth are helix shape.
2	Spur gears are suitable for low speed applications	Helical gears are suitable for high speed applications.
3	In spur gears the teeth are parallel to the gear axis.	In helical gears the teeth axis are inclined to the gear axis.
4	Manufacturing cost is more than helical gears.	Cost is more.
5	In spur gears load carrying capacity is relatively low.	In helical gears load carrying capacity is high due to larger number of teeth are available.
6	Spur gears life is short.	Helical gears life is longer as compared to spur gears.
7	In spur gear the contact between teeth of of gear occurs instantly.	In the helical gears the contact between two gears occurs moderately.
8	Vibration and noise are produced.	Provide smooth and quite operation.
9	Spur gear teeth are subjected to impact of loading.	Helical gear teeth are subjected to gradual loading.
10	In spur gears the teeth are linear and mount parallel on different shafts.	In Helical gears teeth are cut on angle to face of the gear.
11	Spur gears are less strong due to teeth bearing extreme load.	Helical gears are long lasting due to cause of balanced load distribution.
12	Spur gear used in washing machine, And alarm clocks and other devices.	Helical gears used in Automotive applications.

So in this article we learn the topic Difference between Spur Gear and Helical Gear hope you understand well.
