What are the reasons and measures for the anti-loosening of threaded connections?
Reason: Under the action of shock, vibration and load change, the pre-tightening force of the threaded connection may disappear at a certain moment, and the connection may be loosened. The threaded connection at high temperature may also loosen due to differences in temperature deformation and other reasons. Therefore, anti-loosening must be considered in the design.
Measures: Use additional friction to prevent loosening, such as slotted nuts and cotter pins, stop washers, etc., and other methods to prevent loosening, such as punching method to prevent loosening, and bonding method to prevent loosening.
