Evaluation Method of Rolling Bearing Quality (Part II: Experiment)

Rolling bearings is the basic connection parts of machinery, whose quality plays an irreplaceable role for the normal operation of machinery and equipment. Therefore, it is particularly important to make an evaluation of bearing quality. In this paper, factors affecting the machining precision of the tapered roller bearing vibration quality were analyzed using the grey system theory together with the classical statistic theory. The test object is 30204 tapered rolling bearing. It is obtained that the roller spherical runout range, the outer raceway angle error, the average of roller roughness and the roller convexity range are the main factors which affect the tapered roller bearing vibration quality. In the machining process, due to the controllable of these factors the control of finished bearing quality will come into reality in parts machining process.
