Vibration diagnosis analysis of shaft fault of riveting machine.


Taicang pressure riveting machine equipment axis of rotation may be because of problems in the process of manufacture, installation, in the process of running parts damaged or shaft bending etc cause mass distribution of the axis, eccentric inertia force will form in the axis of cycle agitate forced vibrations of the lateral force, the periodic agitate strength of shaft system can be formed resonance, caused havoc to the shafting, Therefore, the harm caused by unbalance of rotating shaft must be taken seriously. Vibration characteristics of rotor unbalance fault is the direction of vibration is given priority to with radial, which is directly related to the vibration frequency and rotating frequency, and the rotating frequency of the main ingredients, rotor unbalance vibration wave phase and rotating the marked with synchronicity, its amplitude and rotation speed was positively than relationship on the whole, the faster the speed, the amplitude, the greater the speed, the smaller the amplitude is smaller, But there's a big amplitude at the resonance.




When considering the vibration diagnosis of rotating shaft, another situation should be taken into account, that is, the vibration caused by poor shaft alignment caused by equipment error and box deformation in mechanical operation. The vibration amplitude of the riveting machine is not changed much because of the bad shaft, and there is no obvious proportional relationship between the rotational speed of the shaft, plus the direction of vibration is generally axial vibration rather than radial vibration, so it will not cause resonance problems.
