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.
