一种关节轴承及磨损量监测装置

What is AI technical title?
AI technical title is built by Patsnap AI team. It summarizes the technical point description of the patent document.
By designing and installing grooves and cover plates in the spherical bearing, and combining them with resistive wear sensors, real-time monitoring of the lubrication layer of the self-lubricating spherical bearing is achieved. This solves the technical problem of not being able to monitor the wear of the self-lubricating layer in real time in existing technologies, and enables real-time monitoring of the wear state of the self-lubricating bearing, reducing potential safety hazards to the equipment.
