Most of the vibration occurs because the neutrality is not done well during the assembly. We can use the infrared photography technology of the predecessors to heat the bearings, motor housings, couplings and other overheated parts when the equipment is not safe. Differentiate and determine the alignment error of the coupling, and then unite with other prospecting techniques such as vibration analysis, the effect will be better.
In this regard, professional craftsmen conducted research on this.Among them, the torsional vibration of the gear coupling is analyzed and studied, and the axial vibration of the adjacent shaft of the gear coupling has been extensively tested. It is pointed out that if the axial vibration is heavy due to the inconsistent error and the frictional force of the tooth surface Caused, when there is no axial restoring force or thrust bearing will occur relatively large axial movement. The researchers also conducted experiments on high-speed rotating turbo-generators and blowers, and commented on the bending vibration caused by the gear coupling. Under the premise of disobeying different parameters such as trade-offs, lubrication conditions, gaps, errors, and loads, etc. A bending vibration test was carried out on the gear coupling adjoining shaft system; it is concluded that the vibration of the gear coupling is greatly related to the internal and external gear mismatch error and tooth surface friction, especially in the case of high-speed rotation. Extra detailed lubrication of the tooth surface.
