a joint bearing

Abstract

The invention belongs to the technical field of intelligent bearings, and relates to a joint bearing. Including bearing inner ring, bearing outer ring, bearing end cover, self-lubricating layer, flexible circuit board, micro sensor integration system, wireless information transmission system and wireless power supply system; the flexible circuit board is installed on the inner side of the bearing end cover, and the flexible circuit board and the The bearing end cover is thermally fused into one; the micro sensor integration system and the wireless information transmission system are set on the flexible circuit board; the wireless power supply system uses the micro holes on the bearing end cover and the bearing outer ring to integrate with the micro sensor system and wireless information through lines The transmission system is connected; the receiving end coil and the transmitting end coil of the wireless power supply system are placed in the annular groove of the outer ring of the bearing outer ring. The spherical plain bearing adopts the method of wireless power supply based on resonance coupling, which simplifies the bearing structure, increases the function of the bearing, and the detection of the spherical plain bearing is more real-time and efficient, and the operation of the bearing is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of intelligent bearings, and relates to a joint bearing. Background technique [0002] Bearings are known as the "heart" of the slewing support system and are the core components of the slewing support unit. It is widely used in various fields such as aerospace, high-speed rail and automobile hubs, large rotors and precision machine tools, and its development level often represents or restricts the development level of a country's machinery industry and other related industries. [0003] Modern industry under high-tech conditions has higher and higher requirements for equipment reliability, safety and stability. It is precisely because the bearing plays a role in bearing and transmitting loads in mechanical equipment, its operating state will directly affect the performance of the entire equipment. According to information, the equipment failure rate due to bearing damage is about 30% in the field of heavy...
