AI Technical Summary

Technical Problem

Existing technologies cannot accurately identify local wear faults in equipment bearings, resulting in large fault location errors. Traditional detection methods cannot collect dynamic correlation features of angular torque during full-circumference rotation.

Method used

A dynamic torque sensor with an integrated angle encoder is coupled to the inner ring of the bearing to record the angular position and instantaneous torque value, generate an angular torque curve, and bind a virtual bearing model in a VR scene. Dynamic resistance feedback is provided through a force feedback data glove. Combined with VR scene visualization and tactile perception, fault location is achieved.

Benefits of technology

Accurately capture the characteristics of localized bearing wear faults, improve the accuracy and efficiency of fault location, avoid errors caused by subjective human judgment, and reduce equipment operation risks.

Abstract

The present application relates to VR auxiliary debugging and bearing fault positioning technical field, specifically, the present application relates to VR auxiliary debugging and fault positioning method for equipment maintenance, aiming at solving the problem that traditional bearing fault detection adopts visual and static detection, and cannot collect full angle torque dynamic characteristics and large fault positioning error, in the bearing press fitting link, the dynamic torque sensor integrated with the angle encoder is used to collect the instantaneous torque of the full angle, the torque curve of the rotation angle is generated and is associated with the coding storage, when the fault occurs, the measured curve and the standard curve of the same type are called, and are bound to the double virtual bearing model of the VR scene, the virtual driving model is synchronously rotated, the signal module generates the resistance signal according to the torque to control the force feedback data glove, the real rotation feeling is restored by superimposing the viscous damping, the comparison module compares the resistance difference point by point and in the sliding window, if the threshold value is exceeded, the abnormal rotation angle interval is locked, the effective fault area is verified and confirmed through the original point, and the positioning result is output, and the fault positioning precision is improved.
