Online detection device for abrasion loss of radial sliding bearing based on pressure detection

Abstract

The invention belongs to the technical field of detection, and specifically relates to an online detection device for abrasion loss of a radial sliding bearing based on pressure detection. The technical scheme is as follows: the online detection device comprises a stator, a rotor, a pressure sensor, a pressing block, a spring, a ball and a signal processor; the stator is coaxially fixedly connected with a sliding bearing block; the rotor is coaxially fixedly connected with a rotating shaft; the stator is provided with a radial through hole; the pressure sensor is fixedly arranged at an outer port of the radial through hole; the ball is arranged in the radial through hole and in contact with the rotor; the pressing block is arranged below the pressure sensor; the spring is arranged betweenthe pressing block and the ball; the pressure sensor is used for acquiring the change of the spring pressure, forming a monitoring signal and transmitting the monitoring signal to the signal processor; and the signal processor is used for analyzing the monitoring signal, converting the monitoring signal into a rotating shaft position variation, and outputting the rotating shaft position variationto a data acquisition device. The online detection device for the abrasion loss of the radial sliding bearing based on the pressure detection provided by the invention can realize the online detectionof the abrasion loss of the radial sliding bearing.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to an online detection device for radial sliding bearing wear based on pressure detection. Background technique [0002] The monitoring methods for the wear state of radial sliding bearings mainly include oil method, temperature method, vibration method and strain method, etc., limited by the use environment of radial sliding bearings, these methods cannot accurately monitor the wear of radial sliding bearings in real time Quantitative detection. Wuhan University of Technology proposed a "Verification Test Bench and Method for Diesel Engine Sliding Bearing Wear Thermoelectric Monitoring System" based on the temperature method (Patent No.: CN 108844739 A). This method can only locate the fault point, but cannot obtain the path Amount of wear to the sliding bearing. [0003] Only by real-time online monitoring of the wear amount of the radial sliding bearing and an ala...
