Operating characteristics of bearings with magnetic nanoparticles doped lubricant

Abstract

The main aim of the presented research was to investigate the operational characteristics of a bearing when alternative lubricants were used for comparison with a standard lubricant, including that containing magnetic nanoparticles. The bearing was subjected to varying operating conditions, differing in terms of mechanical load status. The monitoring of the bearing operation parameters primarily focused on monitoring the velocity and acceleration of vibrations, as well as the operating temperature of the bearing. The bearing with lubricant doped by magnetic nanoparticles exhibited reduced vibration velocity and acceleration values both under no load conditions and when subjected to a mechanical load. The operating temperature slightly increased during testing in the case of the bearing with nanoparticles compared to the bearing using the original lubricant.
