Helical Gear teeth advantage and application

 

Helical gear
Helical gears have teeth that are inclined to the axis of the gear. For the same tooth width, helical gears have longer teeth than spur gears. Therefore, they can transmit more power between parallel shafts than spur gears.

Helical gear applications
Helical gears are used to transmit heavy loads between parallel shafts at very high rotational speeds. The following are the applications of helical gears in various products.
car gearbox
Printing and other machinery
Conveyors and elevators
Factory automation, etc.

Advantages of helical gears
Higher load carrying capacity and contact ratio compared to spur gears.
Smoother and quieter than spur gears.
Good accuracy level

Disadvantages of helical gears
Less efficient compared to spur gears.
The helix angle also increases the axial thrust on the shaft
