Track bolt anti-loosening method
This is the most widely used method of preventing loosening. This method creates a positive pressure between the thread pairs that does not follow the external force, so as to produce a friction force that can restrain the relative rotation of the thread pairs. This positive pressure can be achieved by pressing the screw pair axially or simultaneously. Such as the use of elastic washers, double nuts, self-locking nuts and nylon insert lock nuts. This anti-loosening method is more convenient to disassemble the nut, but in the environment of shock, vibration and variable load, the track bolt will initially lose its pre-tension due to slack. As the number of vibrations increases, the lost pre-tension will be dull Increased ground will eventually lead to loosening of the nut and failure of the threaded connection.
Using split pin, stop washer and string wire rope, etc. Mechanical anti-loosening methods are relatively reliable. To deal with important connections, mechanical anti-loosening methods should be used.
Spot welding, riveting, bonding, etc. In this method, the threaded fasteners are usually crushed during disassembly and cannot be reused.
After tightening, accept punching points, welding, bonding and other methods to make the threaded pair lose the characteristics of the movable pair and the connection becomes inseparable. The disadvantage of this method is that the bolt can only be used once, and the disassembly is very difficult, and the bolt pair must be crushed to be disassembled
