Bevel gear with curved ,oblique teeth to provide gradual engagement and large contact surface at a given time than an equivalent straight bevel gear .
Spiral bevel gears Features:
1 has higher contact ratio ,higher strength and durability than an equivalent straight bevel gear
2.Allows a higher reduction ratio
3.Has better efficiency of transmission with reduced gear noise
40Involves some technical difficulties in manufacturing
Spiral bevel gears Applications :Automobiles, Tractors, Vehicles, final reduction gearing for ships, Especially suitable for high-speed, heavy load drives.
