AI Technical Summary

Technical Problem

The steel ball and socket mating structure of the weighbridge load cell is prone to wear under complex stress conditions, which leads to a shortened structural life and easy deformation and damage under external force.

Method used

The system employs a combination of a limiting retaining steel and a magnetic push mechanism. The limiting retaining steel mechanically constrains the steel ball's offset, while the combination of magnetic and elastic components limits the steel ball's offset angle. Additionally, a guide groove and an elastic buffer layer are installed on the outside of the ball socket to reduce wear.

Benefits of technology

It effectively prevents the steel ball from detaching from the socket, avoids local stress concentration, improves the fatigue life of the structure, extends the maintenance cycle, and ensures the stability and flexibility of the load transmission path.
