Helical Gears Design of Transmission Systems

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.
