Difference between Spur and Helical Gear

Difference between Spur and Helical Gear Points : Difference between Spur Gear and Helical Gear, Spur Gear vs Helical Gear, comparision between Spur Gear and Helical Gear
Difference between Spur and Helical Gear
Spur Gear
Helical Gear
1.These are particularly loud, due to the gear tooth engaging and colliding. Each impact makes loud noises and cause vibration.When two of the teeth start to engage, the contact is gradual--starting at one end of tooth and maintains contact as the gear rotates into full engagement.
2.There are more competent as less teeth touching when two gears are connected.There are less competent because they have more teeth touching when two gears are attached, leading to increased friction.
3.Spur gears are use in screwdrivers, washing machines, windup alarm clocks, and other devices.Helical gears can be used to adjust the rotation angle by 90 deg.
4.Spur gears cost less to manufacture than helical gear.More costlier due to higher design costs.
5.The teeth on spur gears are straight and are mount in parallel on different shafts.The teeth on a helical gear cut at an angle to the face of gear.
6.Due to less teeth touching while two gears are linked load capacity is fewer.Because the load distributes crosswise more teeth the load capacity is elevated.
7.The most common gears are spur gears and are use in series for large gear reduction.Helical gears work more easily and silently compared to spur gears.
8.Are less tough due to teeth bearing extreme load.These are extra durable due to the cause of even load distribution.
