A Closed Bearing Lubricating Oil Status and Bearing Fault Online Monitoring System

Abstract

The invention discloses an online monitoring system for a closed bearing lubricating oil condition and a bearing fault. The online monitoring system comprises two sealing rings which can be used as polar plates and arranged at two ends of a bearing, guiding lines are connected to and led out from the sealing rings, two simulation switches are connected to the two sealing rings through the guidinglines correspondingly, the two simulation switches are connected with one common capacitance measuring circuit and two individual charge measuring circuits, and the polar plates are controlled to be connected with a chosen circuit through the simulation switches; the simulation switches are connected with a digital port of an embedded system, the embedded system controls and generates control signals to switch the simulation switches, and the embedded system is electrically connected with an upper computer for analyzing signals; the sealing rings on the two sides of the bearing are used as capacitance measuring electrodes and sensing electrodes of the two charge measuring circuits, so that the system can collect the lubricating oil condition of the bearing and charge information, online comprehensive monitoring of the lubricating oil condition can be carried out, the partial fault of the bearing can be monitored synchronously, and the online monitoring system has the characteristics that the precision is high, the use is convenient and the operation is flexible.

Description

technical field [0001] The invention relates to the technical field of industrial equipment monitoring instruments, in particular to an on-line monitoring system for the lubricating oil state and bearing failure of a closed bearing. Background technique [0002] Bearing is an essential part of mechanical equipment. Its main function is to support the mechanical rotating body, reduce friction during its movement, and ensure its rotation accuracy. The state of bearing lubricating oil plays a decisive role in the working state of the bearing. At present, with the rapid development of intelligent algorithms, big data, etc. and their applications in robots, intelligent robots have become a hot research field today. The robot system needs to monitor the status of each part to obtain the working status of the robot. Bearings play an irreplaceable role in the execution of robot actions. With the operation of the equipment, the lubricating oil will absorb moisture and mix with dust...

AI Technical Summary

Problems solved by technology

With the operation of the equipment, the lubricating oil will absorb moisture and mix with dust due to the influence of the environment. At the same time, it will also undergo oxidation, decomposition and other degradation processes under high temperature and high pressure conditions. It will also be mixed with metal particles to reduce friction performance. During the use of lubricating oil There is also the possibility of leakage in

These processes will lead to the reduction of bearing lubrication efficiency and seriously affect the normal operation of the equipment.
