AI Technical Summary

Technical Problem

Existing bearing electrocorrosion testing equipment suffers from poor contact between the wires and the bearing mounting platform surface, and between the brushes and the shaft, due to vibration. This affects the accuracy of current and voltage detection, resulting in large fluctuations in the test data.

Method used

The carbon brush is fixed by the rear auxiliary plate, and the rear auxiliary plate and bearing mounting platform are fixed by the positioning column to reduce vibration. At the same time, the wire is fixed in the positioning column to ensure that the brush and the positioning column move synchronously and avoid asynchronous lateral vibration. Combined with the lifting mechanism and electromagnetic mechanism, the brush is ensured to be in close contact with the shaft.

Benefits of technology

This reduces the fluctuation range of the detection data, improves the accuracy of current and voltage detection, and ensures the stability of the detection results.
