Abstract

The invention relates to a temperature self-monitoring ball bearing, and belongs to the technical fields of a bearing and monitoring thereof. A mounting barrel is fixed on the end face of an inner ring through a bolt; an exciting plate is fixed on the end face of an outer ring through a bolt; exciting magnets are evenly embedded on the exciting plate; a circuit board and a sensor are arranged on a bottom plate of the mounting barrel; a metal film is pressed on the end face of the lateral wall of the mounting barrel through a bolt and a pressure ring; an O-shaped seal ring is arranged between the outer surface of the lateral wall of the mounting barrel and the inner surface of the outer ring; a cantilever beam is arranged on the metal film; an excited magnet is arranged at one side of the free end of the cantilever beam, near the exciting magnet; a piezoelectric diaphragm is adhered to the other side; an energy harvester is formed after the cantilever beam is adhered to the piezoelectric diaphragm; the energy harvester and the sensor are respectively connected with the circuit board through a lead group 1 and a lead group 2. The temperature self-monitoring ball bearing has the advantages of having a self-energized sensing monitoring function, being used as an independent standard component, having no need on change of the structure of the mounting equipment, and being capable of achieving real-time online monitoring in the real sense.

Description

technical field [0001] The invention belongs to the technical field of bearings and monitoring thereof, and in particular relates to a temperature self-monitoring ball bearing. Background technique [0002] Bearing is a typical mechanical basic part, which is widely used in the fields of machinery, vehicles, aerospace, ships and energy; however, bearing is also one of the most vulnerable parts in rotating machines, and 30% of rotating machinery failures % is caused by bearing failure. Therefore, the state monitoring and early fault diagnosis of bearings have attracted people's attention. On-line monitoring of bearing status has gradually become an indispensable technology in the fields of large wind turbines, ships, high-speed rail, and aircraft. The indicators to be monitored include temperature, vibration, speed, and noise. Early bearing monitoring systems were mainly plug-in. One of the disadvantages was that the distance between the sensor and the signal source was rel...
