NettetUsing this position/vibration data from both axis, analysts can create an orbit that can be used to measure the total vibration of the shaft’s centerline as it rotates in the bearing sleeve. An orbit will provide the peak-to-peak displacement and direction of the vibration relative to the shaft centerline. Nettet6. des. 2024 · The meshing stiffness and damping between the gears are obtained by current methods in the listed references, as well as the contact stiffness and damping in bearings. The liner stiffness and damping model is used. The effects of the bearing clearance, external torque, and input speed on vibrations of the system are analyzed.
Vibration Analysis of Deep Groove Ball Bearings With Local
NettetJournal bearings are a subset of bearings used to support rotating shafts that use the principle of hydrodynamic lubrication. Opposed to anti-friction bearings that operate using rolling components inside the bearing (i.e. balls, rollers), journal bearings operate by … Nettet6. mai 2024 · Timely failure detection for bearings is of great importance to prevent economic loses in the industry.
