Abstract

The application belongs to the technical field of self-lubricating bearings, and particularly relates to a combined overheat-preventing self-lubricating bearing set. In the application, when the bearing main body is used in a rotating way, if the rotating speed is influenced, the moving speed of the bearing outer joint and the permanent magnet ball on the bearing main body is reduced, the magnetic induction of the permanent magnet ball and the pressing broad plate is correspondingly changed, namely when the permanent magnet ball is slowly close to the pressing broad plate, the telescopic contact slides towards the movable groove under the action of magnetic repulsion force of the permanent magnet ball, the compression spring is compressed, the first rack drives the conversion gear to rotate, the second rack drives the finger rod to slide in the groove until the finger rod contacts the pressure sensor, the pressure sensor transmits the detected pressure signal to the peripheral computer, and the peripheral computer controls the small hydraulic push rod to automatically work, so that the automatic conveying of lubricating oil is finished, and the defect of difference in accuracy caused by manual monitoring is avoided.
