Dynamic and thermal coupling modeling analysis of full-ceramic angular contact ball bearing considering sliding
Bibliographic record
Abstract
The sliding contact model and sliding dynamic model between ball and outer ring are established to investigate the ceramic bearing vibration characteristic when ball slides. The vibration characteristic and periodic rules of the system are analyzed by calculation results of the model. The heat generation model of bearing slippage is established, and the influence mechanism between temperature and oil film viscosity caused by slippage is analyzed. It can be seen from the calculation results that the contact deformation between ball and outer ring increases with the increase of radial load, and the contact deformation is smaller than the calculation results of Hertz contact model. An experimental platform for testing vibration and temperature under radial load conditions is established. The experimental results show that the vibration characteristic and temperature variation rule of bearing under large load conditions are consistent with the calculation results of the model. The average error of vibration amplitude and temperature is only 1.09% and 1.3% at 10000 r/min. It can be seen that the model established in this paper can simulate the dynamic characteristic of ceramic bearing when ball slides, and provides a certain theoretical basis for the research of rotating machinery mechanism under sliding condition.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
