1) Description of sprail bevel gear
Sprial bevel gear is a special type bevel gear, a sprial bevel gear with a cruve helical angle.
Spiral bevel gear provide gradual engagement and larger contact surface at a given time than an
equivalent straight bevel gear.
2) Gear quality of sprial bevel gear
Standard sprail bevel gear manufactured by gear teeth milling processing.
The sprial bevel gear can be with gear teeth grinding processing after heat treatment.
The gear teeth quality can reach ISO 5-6 grade (AGMA 10-11 Grade)
3) Features of Spiral Bevel Gear
a) Allow higher reduction ratio
b) Higher contact ratio, higher strength and durability than equivalent straight bevel gear.
