Measurement Method for Contact Load of Bearings Based on Intelligent Rollers

Abstract: In response to the difficulty in measuring the contact load of three row cylindrical roller bearings, a continuous measurement method for contact load is proposed based on finite element simulation and harmonic analysis, and the intelligent rollers are designed for measuring the contact load of the bearings. Taking main bearings for a shield tunneling machine as examples, the corresponding load sensors and the rollers are designed based on continuous measurement method for contact load. Then the ability of eliminating the influence of roller rotation angle on load measurement by continuous measurement method for contact load is analyzed through virtual bridge simulation. Finally, the linear relationship between output of load sensors and contact load is obtained through calibration experiments to achieve contact load measurement. The results indicate that the circumferential strain on inner hole wall of the rollers is a harmonic function with respect to roller rotation angle;the designed load sensors can effectively eliminate the influence of roller rotation on load measurement and achieve continuous measurement for contact load of the bearings.
