1) Features of the Helical Gear
A slanted tooth trace is one of the significant features of the helical type of gear.
Compared with other gears like the spur or worm, the helical has a larger contact surface enabling better torque transfer.
At the same time, the helix hand is the opposite. A helical gearbox is widely used to reduce the speed and increase the torque.
2) Advantages of Helical Gear
a) Guaranteed long life ensuring optimal performance for many years.
b) Minimal damage to the teeth of the gear due to even load distribution.
c) Can be made easily by gear manufacturers using the gear hobbing method.
3) Applications of Helical Gear
a) Textile Industy
b) Fertilizer Industry
c) Conveyors
d) Elevators
e) Rolling Mills
