Auto and motorcycle screw loose control technology
Auto and motorcycle in motion will be strongly vibration, especially in complex situations road is even more so. Thread fasteners by twisting is generated when tight axial pre-tightening force to achieve. In violent vibration of the preloaded force reduce gradually will lead to loose. Bolt looseness in the form of lateral inversion, the translation of the lateral and axial strain, three forms, these loose form can cause screws or nuts and supporting surface displacement between-from loose phenomenon to appear.
