Technical and Economic Advantages of Cold Forged Planetary-Bevel Gears Developed with Net Shape Teeth and Splines
Bibliographic record
Abstract
<div class="section abstract"><div class="htmlview paragraph">The search for more technical and economical competitive automotive products motivates even more the engineers to research for solutions that reduce manufacturing costs and lead-time. Bevel gears are applied extensively in the automotive industry since the invention of the transmission differential, however; few changes of the design have been done on these components in the last decades. Currently, the planetary-bevel gear blanks are hot forged with posterior cutting of the teeth and broaching of the spline, eventually, some planetary-bevel gear blanks have the teeth warm forged.</div><div class="htmlview paragraph">The process to cold forge the teeth and the splines results as much technically benefits for the product application as manufacturing costs and lead-time reductions.</div><div class="htmlview paragraph">This paper presents a planetary-bevel gears manufacturing concept for passenger and light commercial vehicles, where the cold forged teeth and splines present technical and economic benefits to the automotive differential transmission system.</div></div>

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.
