1) Description of Helical Gear Shaft
The spur gear that has helix teeth (helicoids teeth) is called Helical Gear. Helical gears can transmits force
between parallel shafts and non parallel shafts. They are widely used in different industries, such as the
automotive, and in industrial machinery. Helical gears can bear load more than spur gears and work more quietly.
Spur gears make noise due to sudden contact between gear teeth at the time of engagement, but helical
gears make smooth contact from one edge of the tooth the other. This provides smooth and noiseless
operation with higher efficiency than spur gears.
2) Classification of Helical gears
a) Parallel helical gears (used to transmit power between parallel shafts)
b) Double helical gears or herringbone gears.
c) Cross helical gears or skew gears (used to transmit power between non parallel shafts)
