Question

What is backlash error?

Answer 1

Backlash Error is a error.

In case of a micrometer screw gauge, the backlash error is the error in measurement due to backlash of the internal gears.

Thank you.

Answer 2

Answer:It is an error in the Screw gauge or Micrometre screw

Explanation:

In case of micrometre screw gauge the backlash error is the error in which measurement due to backlash of the internal gears.In a pair of machine gears the distance between two space and tooth thickness is called as backlash.

Tooth thickness is the distance between two adjacent teeth measured along the pitch circle . Practically the tooth space is always greater than the tooth thickness to prevent jamming of the gears due to thermal expansion
