What are the reasons and measures for preventing loosening of threaded connections?
Reason : Under the action of shock, vibration and variable load, the pre-tightening force may disappear at a certain moment, and the connection may loosen. The threaded connection at high temperature may also loosen due to temperature deformation differences. Anti-looseness must be considered when designing.
Measures : Use additional friction to prevent loosening, such as grooved nuts and split pins, stop washers, etc., and other methods to prevent loosening, such as punching to prevent loosening, and bonding to prevent loosening.
