Journal ArticleDOI
Increasing the Strength of Standard Involute Gear Teeth with Novel Circular Root Fillet Design
Vasilios Spitas,Christos Spitas +1 more
TL;DR: The analysis demonstrates that the novel teeth exhibit higher bending strength (up to 70%) in certain cases without affecting the pitting resistance since the geometry of the load carrying involute is not changed.
Journal ArticleDOI
A FEM Study of the Bending Strength of Circular Fillet Gear Teeth Compared to Trochoidal Fillets Produced with Enlarged Cutter Tip Radius
Christos Spitas,Vasilios Spitas +1 more
TL;DR: In this paper, a comparison of the bending strength between the CF and the non-standard large tip radius TF designs spanning the entire usable tooth number range using FEA was made, and the results suggest a systematic advantage of the CF over the stronger variants of the TF for numbers less than 17 teeth.
Journal ArticleDOI
Analysis of systematic engineering design paradigms in industrial practice: A survey
TL;DR: The engineering design process is analysed and different contributing paradigms are identified, including the abstraction-to-detail paradigm mostly associated with systematic design, to build an understanding of the observed discrepancy between the formal systematic design theory and many current design practices in the industry.
Journal ArticleDOI
Optimum gear tooth geometry for minimum fillet stress using BEM and experimental verification with photoelasticity
TL;DR: In this paper, the concept of non-dimensional gear teeth is introduced to reduce the total number of design variables by interpolation of tabulated values, which were calculated previously by applying the BEM on nondimensional models corresponding to different combinations of the design parameters.
Journal ArticleDOI
Fast modeling of conjugate gear tooth profiles using discrete presentation by involute segments
TL;DR: In this article, the authors propose a method of discretizing the gear tooth flank in involute segments for the determination of conjugate gear tooth profiles, which is faster than the standard theory of gearing and is particularly useful in problems requiring iterative calculations of the tooth geometry such as gear optimization.
