What is backlash

Question

What is backlash

Accepted Answer

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, there may be a slight delay or movement before the gear engages in the opposite direction due to backlash.
Backlash can affect the accuracy and precision of mechanical systems, especially in applications where precise positioning is required.

Accepted Answer

example, in a pair of gears, backlash is the amount of clearance between mated gear teeth
