CONTACT STRESS AND RADIAL STIFFNESS OF A CYLINDRICAL ROLLER BEARING WITH CORRECTED ROLLER GENERATOR
Bibliographic record
Abstract
A method has been developed to study the radial stiffness of a cylindrical roller bearing with corrected roller generator. First, the finite-length contact question of roller-race contact was solved by cutting contact surface into slices and considering the influences among slices by a flexibility coefficient matrix, which was more accurate than the traditional method. Further, the more precise load-approach function of the contact of race and roller with corrected generator was determined. Then, the radial stiffness of a cylindrical roller bearing has been derived by coupling this load-approach function into a complete bearing mechanical model. Results show that the corrected roller generator has a great influence on the bearing radial stiffness. The maximum stiffness difference among the cases of straight and crowned generators is 28.7%. The bearing radial stiffness decreases rapidly with the rise of profile maximum deviation h max . It is worthy noting that there is a sudden change of stiffness with the adding of load when the bearing is with clearance.

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.
