axial run-outs, of the backlash, the root clearance and of the free play. Note: When a gear set must be turned because of wear, it is no longer possible to align the gears by means of the backlash. The drive must be set up by means of the root clearance.A suitable guide value for the tooth tip play is 0.25 to 0.3 times the module.
In mechanical engineering, backlash, sometimes called lash or play, 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".
