What is a common problem that results from misalignment in gear systems?

Misalignment in gear systems often leads to the formation of hook teeth, which is a common problem in such mechanisms. When gears are not properly aligned, the contact point between the gear teeth is displaced, causing uneven wear on the teeth. This misalignment can result in the teeth being damaged or deformed, often leading to a hook shape. Hook teeth can then create further operational issues such as increased vibration, noise, and potential failure of the gear system. Addressing alignment is crucial to maintain the integrity of the gear teeth and the overall performance of the system.
