What is the difference between straight teeth and helical teeth on the large girth gear of a ball mill?

2026.03.19

The large girth gear is a critical component responsible for driving the rotation of a ball mill's shell. Its tooth profile design is primarily categorized into two types: spur gears (straight teeth) and helical gears (helical teeth). These two types exhibit significant differences in terms of load-bearing characteristics, operational smoothness, and manufacturing complexity. With spur gears, the teeth run parallel to the gear axis. Their machining is relatively simple, resulting in low...
