Question

What is backlash error and how to avoid it

Answer 1

Backlash error occurs in screw gauge, when we try to rotate the screw very fast to ... reading, toavoid this we should rotate the screw slowly in only one direction.Backlash, a clearance between mating gear teeth, is built into speed ... On the other hand, the same clearance causes lost motion between reducer input .... overheating of the gears and bearings, and even seizing and failure. .... Backlash should be avoided in case of measuring instruments like lead screw, screw gauge etc.

Heya!
--------

=============================================================

♦Back Lash Error =>
===============

◾When the sense of rotation of the screw is suddenly changed , the screw head may rotate but the screw itself may not move forward or backward .

◾This may change the scale reading even by the actual movement of the screw . This is known as Back Lash Error.

♦Causes =>
==========

◾Loose fitting of the screw

◾Due to wear and tear of threading due to pronologed use of screw .


♦Reduced by =>
==============

◾Rotating the Screw in the same direction for a particular set of Observations !
