Abstract

The invention discloses an embedded sliding bearing lubricating film pressure wireless sensing and monitoring device which comprises a wireless monitoring circuit and a wireless power supply structure. The wireless monitoring circuit comprises a pressure sensor and a signal conditioning and wireless transmitting circuit which are connected in sequence; the wireless power supply structure comprises a wireless power supply coupling mechanism and a wireless power supply peripheral circuit, the wireless power supply coupling mechanism comprises a secondary side magnetic core winding arranged on the rotating mechanical shaft and a primary side magnetic core winding arranged on the periphery of the secondary side magnetic core winding, and an air gap exists between the primary side magnetic core winding and the secondary side magnetic core winding. The wireless power supply peripheral circuit comprises a primary side circuit and a secondary side circuit, the primary side circuit is connected with an external direct current power supply, and the secondary side circuit comprises a micro lithium battery. Wireless monitoring of the pressure of the lubricating film of the sliding bearing can be realized under the condition that the complete structure of the bearing is not damaged.

Description

technical field [0001] The invention belongs to the technical field of bearings, and relates to an embedded sliding bearing lubricating film pressure wireless sensor monitoring device. Background technique [0002] Sliding bearings are widely used in large ships, ships, turbines and other mechanical equipment due to their stable and reliable operation. Its safe and reliable operation is the basis for ensuring the stable operation of the equipment. Studying and using advanced testing technology to monitor its condition can not only obtain important characteristic parameters of sliding bearing, but also predict faults through monitoring data, and carry out equipment maintenance and replacement without affecting the operation of equipment, thereby avoiding unsafe accidents. [0003] However, the working conditions of sliding bearings are complex in specific applications, and due to the tightness of the sliding bearings, it is difficult to accurately monitor the pressure of the...
