+86-18057366698 Contact UsThe lock nut is also a screw cap. It is a component that is screwed together with a nut or bolt to have a firm function. All the processing and production of machinery and equipment are necessary to use the original. The lock nut is to make the gap between the machinery and equipment. The parts connected to the same can only be connected with the same type of standard lock nuts and screws by relying on the threads on the inner side.
1. Anti-loosening of machinery and equipment
The lock nut stopper is used to immediately limit the relative rotation of the lock nut pair. Such as the use of difficult-to-open gear pins, connecting stainless steel wires and stop sealing rings, etc. Since the lock nut stopper has no pre-tightening force, the anti-loosening stopper can only be effective when the lock nut nut is loosened and returned to the stop part. Therefore, the method like the lock nut does not prevent loosening but only prevents explosion. out.
2. Riveting and anti-loosening
After tightening, using punching, electric welding, bonding and other methods, the lock nut pair lacks the movement characteristics and the connection becomes undetachable. The disadvantage of this method is that the bolt can only be used once, and the disassembly and assembly are very difficult. It is necessary to destroy the anchor bolt pair to be disassembled.
3. Anti-loose by friction
It is a widely used anti-loosening method, which generates a positive pressure between the lock nut pair that does not change with the action of the external force, so as to generate a sliding friction force that can block the relative rotation of the lock nut pair. This kind of positive pressure can be carried out by clamping the lock nut pair in the radial direction or in the other two directions. Such as the use of ductile sealing rings, double nuts, lock nuts and insert lock nuts.
4. Anti-loose structure
It uses the structure of the lock nut to prevent loosening of the lock nut for Down syndrome.
5. Flushing method to prevent loosening
After the nut is tightened, the punching point at the end of the thread will damage the thread; the anti-loosening is usually applied to the threaded surface with an anaerobic adhesive. After tightening the anti-loosing nut, the adhesive can dry and solidify independently, and the anti-loosing effect is expected good. The disadvantage of this method is that the bolt can only be used once, and it is very difficult to disassemble and assemble, and it can be disassembled if it is necessary to damage the anchor bolt pair.
