AI Technical Summary

Technical Problem

The lack of an effective limiting structure in existing bearing hardness testing makes it easy for bearings to shift and deviate, affecting the accuracy of the test.

Method used

A shaft limiting mechanism is set on the surface of the testing disc of the hardness tester, including a tray, fixed groove, fixed plate, core hole, T-shaped hole, leg plate, limiting plate, side strip groove, V-shaped groove and upright ear plate, which are connected by bolts to form a clamping structure to ensure the stability of the bearing during the testing process.

Benefits of technology

This effectively ensures the bearing's compressive stability during hardness testing, guarantees the accuracy of the test, and facilitates the disassembly and maintenance of the shaft limiting mechanism.
