Research and application of methods of technical diagnostics for the verification of the design node

Research and application of selected diagnostic methods for assessing the condition of the gearbox of machining center accrued from collaboration applied between our work location and the company Regada, Ltd. Prešov. The requirement of our partner was directed to identify the current state of the abrasive particles in oil, to assess the condition of the contact surfaces in the running-in period and to assess the condition of the lubricant. Implemented analysis of gear oils have been prefentially oriented to identify the wear particles produced during running-in period and in the first hours of operation of contact surfaces. At the same time the correlation between total content of Fe (iron) particles in oil and accrual of kinematic will in tooth meshing of toothed ring of the gearbox was monitored. In quantification of the content of ferrous wear particles the impact of the running-in processes on the contact surfaces (bearings, toothing), which can cause negative side effects, was assessed.
