Vibration characteristics of a double-row tapered roller bearing with raceway defects
Bibliographic record
Abstract
Double-row tapered roller bearings (DTRBs) offer significant advantages, including high load-carrying capacity, long service life, and the ability to withstand combined radial and axial loads as well as bending moments. DTRBs are widely used in mechanical equipment and machinery, such as precision machine tools, automobiles, rail transit, and wind turbines. While previous studies have primarily focused on the static analysis of DTRBs, few have investigated their vibration mechanisms. To explore the dynamic characteristics of DTRBs, a comprehensive dynamic model was developed, incorporating local defects. This model reveals the vibration behavior of DTRBs with local defects and analyzes the impact of bearing defects on vibration characteristics. The findings provide a theoretical foundation for DTRB defect diagnosis and serve as a basis for future studies on the dynamics of various roller bearings.

How this classification was reachedexpand
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.
