The pinion from the drive of the cement mill was failed; the teeth cracked and spall occurred on the sides of several teeth. The failure was only located on one side of the pinion. This type of failure is common with surface-hardened gears.
When it comes to transmissions, helical is the most commonly used gears and it even generates large amounts of thrust. It's Advantages:-The angled teeth engage more gradually than do spur gear teeth so that they can run more smoothly. Helical gears, as well as helical gearboxes, are highly durable and ideal for high load applications.
