Because the eccentric self-locking nut has the automatic tightening function and the absorption of high-frequency vibration function, it can realize the safe application in high vibration frequency, high vibration strength and long vibration time, especially in the vibration frequency alternating occasions.When the vibration frequency is high, the vibration strength is large, the vibration time is long, especially the vibration frequency intersection, in addition to glue, soldered nut, the current anti-loosening nut can not achieve safety and loosening (some anti-loosening nuts can only achieve the effect of nut falling off).
1. The axial vibration force causes the nut pretension force is instantly "0", when the vibration force disappears by the fastener, the screw elastic recovery force, the axial impact on the nut, the greater the impact force, the higher the impact frequency, the greater the impact frequency change range, the longer the impact time, the more likely it is to loosen the nut!
2. Sometimes although the axial vibration force is not large, resulting in the instantaneous relative reduction of the nut pretension force is not large, but due to the high vibration frequency, and the intersection, at this time, there will be a frequency and the nut, or nut loose parts resonance, will also cause loosening!
Solve the triple theory of high vibration strength, high frequency and frequency alternating nut loosening:
1. Use the radial friction torque to prevent the main body and combine the axial friction torque.
2. The structural anti-loosening design is adopted to realize the automatic tightening function of nuts and the joint elastic friction self-locking function.
3. Use embedded shock absorption material to absorb self-excited vibration, and combine the damping and anti-loosening function after deformation of shock absorption material.
