1) Description of spiral bevel gear
Spiral bevel gear is a bevel gear with helical angle of spiral teeth
.
Bevel gear with curved, olique teeth to provide gradual engagement and larger contact surface.
2) Features of spiral bevel gear
a) With higher contact ratio, higher strength and durability compared with an equivalent straight bevel gear.
b) Allows higher reduction ratio.
c) With better efficiency of transmission with reduced gear noise.
3) Applications of Spiral bevel gear
Automobiles, tractors, vehicles, final reduction gearing for ships.
Suitable for high-speed, heavy load drives.
