Abstract
An intelligent bearing includes a bearing body and a detection component. The bearing body includes an inner ring, an outer ring, a rolling body and a cage, and the detection component includes a conductive layer and friction layers. The inner ring is rotatably fixed within the outer ring and spaced apart from the outer ring. The cage is rotatably disposed between the inner ring and the outer ring. The rolling element is rotatably disposed in the cage. The friction layers are arranged at intervals between the inner ring and the outer ring. The conductive layer is attached to a first protrusion of the cage protruding toward the friction layer, rotates with the cage between the inner ring and the outer ring, and contacts and rubs against the friction layers fixed between the inner ring and the outer ring, to form a tribovoltaic effect and generates a direct current.
