摘要：The rolling bearing is a multi-body rotating system with rolling elements, inner, outer rings and cage transmitting motion and load from rotor to the bearing supports and machine body. The existence in the new bearing elements of micro-defects (surface roughness Rz, Rzmax, waviness Ws and of size rolling elements) generate stochastic high frequency vibration. It is important for manufacturing technology to examine quality of new bearings elements. This paper considers a new deep groove ball bearings single row 6205 2RSL C3/P6 experimental vibration testing method for quality assessment of new bearing separating micro-defects in inner raceway from micro-defects in outer races. This method is based on high frequency vibration measurements of lubricated and dry bearings with varied loads.
