Calculation methodology of dry sliding bearing of metal-polymeric reverse friction pair

Calculations methodology is created for the comparative maximum load in the dry friction sliding bearing of metal-polymeric friction pair. If the load value exceeds the allowable load, then the construction of the sliding bearing with the reverse slide pair is considered to be reliable. The experimental data of friction coefficient for comparable calculations were gain by the original testing-bench for sliding friction pairs. The verifying thermal calculation of the sliding bearing allows to determine the maximum temperature and loading force of the sliding bearing. This temperature predetermines the fitness for using this polymer type and selection of the type of polymeric material for coating of the shaftVytauto Didžiojo universitetasŽemės ūkio akademij

Investigation of hydrodynamic parameters of sliding bearing with inverse friction pair

2-s2.0-84905860821 - ScopusInvestigation of some hydrodynamic parameters of metal/polymer (Phenilone F-S2) inverse friction pair (IFP) is performed: shaft location co-ordinates, thinnest oil layer, polymeric layer deformations, highest hydrodynamic pressure, friction coefficient. The received experimental values were compared to the theoretical data according to the theoretical formulas. The research results and calculations show that presented methodology could be used for calculation of shaft coordinates for lubricated metal-polymeric sliding bearing with inverse friction pair. When the main parameters of hydrodynamic wedge are the same, the inverse friction pairs can operate under hydrodynamic lubrication at 30% higher loading, comparing to base friction pair. Experimental data show that the formula for calculation of polymeric layer deformation and hydrodynamic pressure should be improved taking into account particular bearing’s length and varying of pressure along the bearing axisVytauto Didžiojo universitetasŽemės ūkio akademij
