Backlash is the play or movement between mechanical components due to gaps or clearances.

• Backlash refers to the amount of movement or play that occurs between two mechanical components.

• It is caused by gaps or clearances between the components, which can result in imprecise or inaccurate movement.

• Backlash is commonly seen in gears, where the teeth have small gaps to allow for smooth engagement.

• For example, when a gear is rotated in one direction and then quickly reversed, ther...read more
