Failure Analysis of Output Shaft in the Gearbox Transmission
Bibliographic record
Abstract
The objective is to analyze the fracture of output shaft in the two speed gearbox, which was broken after one year service. By means of software KISSsoft and KISSsys, a strength calculation has been carried out on the transmission system, which shows that the output shaft was designed properly and it should be able to withstand the loads applied. The metallurgical microstructure inspection and SEM observation have been conducted to seek the failure reason. Lots of silicate inclusions in the fracture origin have been found out by SEM observation, which cause the initiation of shaft failure most probably. Obvious dendritic segregation in the center area of the fracture surface, intercrystalline fracture, cleavage fracture and unreasonable metallurgical microstructure show the evidence that the forging process and the heat treatment on the output shaft are not qualified, which can contribute to the initiation and spread of shaft fracture.

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.
