AI Technical Summary

⚠Technical Problem

Existing methods for determining creep in bearing rings are inefficient and prone to human error, leading to potential damage and increased maintenance costs due to unchecked micro-movements.

⚗Method used

A device comprising 3D accelerometers and a control unit is used to measure and calculate creep by analyzing phase differences in acceleration data from sensor units fixed to the bearing ring and shaft, compensating for tilt and utilizing gravitational acceleration.

🎯Benefits of technology

Provides precise, automated, and cost-effective monitoring of bearing ring creep, reducing downtime and maintenance costs by detecting early signs of damage.
