The Precise Forming of Automobile Start Gear Shaft
Bibliographic record
Abstract
The start gear shaft is the key part of automobile starter, it is involute small module internal gear with addendum modification. It is step shaft with H/D>6 in the outline. Because of the concentric degree demand of the internal gear and the outline step shaft is higher, length of below shaft is large and diameter is small, So plastic forming of the shaft is very difficult. Meeting the needs of markets and improving comprehensive function of automobiles, the high efficient precision forming technology method of single-step chipless-forming for internal gear tooth surface and external step shaft is put forward based on analysis, study and repeated test. In the same time, a set of high accuracy die with simple novel structure and long service life is designed and manufactured. The advantages of the method have been verified that utilization ratio of material and production efficiency is high. For this reason, the method is profitable reference for producing the same type of complex shape gear shaft.

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.
