1. Move an axis in one direction farther than the maximum possible backlash. (Example .020, hopefully less than that is needed!) 2. Mount a dial indicator and zero it. 3. Move the axis again in the same direction for a specific distance (it doesn't matter how far). 4. Move the axis backwards the same distance.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
The maximum angle that allows the gear to move when the other mating gear is held stationary. (4) Radial backlash ( j r ) The radial Backlash is the shrinkage (displacement) in the stated center distance when it is set so the meshed tooth flanks of the paired gears get contact each other. (5) Axial Backlash ( j x )
