LOAD ANALYSIS OF MISALIGNED GEAR COUPLING USING THE CLEARANCE DISTRIBUTION OF MESHING TEETH
Bibliographic record
Abstract
A gear coupling is one of the most common types of couplings in use today. Its popularity is due to its ability to accommodate axial, radial and angular misalignments which result in uneven distribution and sharing of transmitted loads between meshing teeth and may enhance deterioration in the coupling due to fatigue if not accounted for. In this study, load sharing among coupling teeth in the presence of angular misalignment is investigated. A procedure is introduced in which the coupling teeth are modelled as linear springs whose stiffnesses are equal and determinable from the coupling geometry and material. It was found out that the external male teeth are separated from the corresponding female internal teeth by distances (clearances) determined from the backlash and the angle of misalignment. Therefore, when the coupling is loaded, the teeth with small clearances come into contact before the ones with larger clearances. This results in an uneven distribution of loads among contacting teeth where some teeth may be completely unloaded or heavily loaded; depending upon the angle of misalignment, backlash and their clearance distribution. This produces cyclic loading on teeth during coupling rotation and may result in failure by fatigue.

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.
