Bearing Defect Classification Algorithm Based on Autoencoder Neural Network

Figure 2

Three types of bearing defects. (a) Abrasion: wear caused by friction between a bearing and a rough object as it moves on a production line. (b) Bruise: when moving between stations, the bearing transfer device does not fix the bearing, which causes concavity from the collision between the bearing and other objects. (c) Overgrinding: in the machining process, excessive grinding of the bearing is caused by machine vibration or incorrect parameter settings.
