A bevel gear with helical teeth is called a _____ bevel gear

Explanation:
Bevel gears are named by how their teeth engage on the conical pitch surface. When the teeth are curved or angled rather than straight, they form a spiral (or helical) gear on the bevel family. The term spiral bevel gear describes teeth that wrap around the pitch cone, enabling smoother contact and higher load capacity than straight teeth. If the teeth were straight, it would be a straight bevel gear; if the shafts didn’t intersect, you’d be looking at a hypoid gear, which is a different arrangement. So a bevel gear with helical teeth is a spiral bevel gear.
