Helical gear sets are commonly used in helical gearboxes due to their smooth operation and ability to handle high loads. They consist of two or more gears with helical teeth that mesh together to transmit power and motion.
Helical gears offer advantages such as reduced noise and vibration compared to spur gears, making them ideal for applications where quiet operation is important. They are also known for their ability to transmit higher loads than spur gears of comparable size.
The teeth are twisted oblique to the gear axis. The hand of helix is designated as either left or right. Right hand helical gears and left hand helical gears mate as a set, but they must hae the same helix angle .
1. Has higher strength compared with a spur gear 2. More effective in reducing noise and vibration when compared with spur gear 3. Gears in mesh produce thrust forces in the axial direction
