Experimental Research of Rolling Bearings

Based on the results of multiple-factor experiment the dependence of the moment of resistance to the bearing rotation on the load as well as on the shaft speed, the oil level and their interaction is investigated. Statistical analysis of experimental data was performed through the use of STATGRAPHIC PLUS package. Experiment results adequacy is proved by «the normal distribution of the residuals». Relative impacts of the factors and their interactions are defined by using the dispersive analysis. Three-factor regression equation of the moment of resistance to the bearing rotation is received by means of ANOVA. Experimental and statistical analysis technique can be used in further studies of different types of bearings.
