Research ArticleOpen accessIn the keywordsContributions to the Synthesis of Fixed Axle Gears by Avoiding the Interference PhenomenonRelly Victoria Virgil PetrescuIt can be seen that the minimum number of teeth required to avoid interference for the standard pressure angle, normally on the alpha0 = 20° decomposition circle, is 13, corresponding to a transmission ratio i = 1 and increases with the transmission ratio i reaching to the maximum value of 18 teeth for i>100. For normal transmission ratios, values ranging … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 6,488 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKinematic and Dynamic Analysis of a Classic, Three-Axis Manual Gearbox, Without a Direct SocketRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuFixed axis mechanical transmissions today have the largest spread on the entire planet, being practically used in almost all areas. From the gearboxes of the vehicles to the stationary reducers, used in the electrical, electronic and electro technical equipment, in the heavy industry but also in the light industry, in energy and in transport, practically the transmissions with fixed axes … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 24 May 2020 · 7,673 accessesView PDFCite
Review ArticleOpen accessIn the abstractSome New Gears AspectsFlorian Ion Tiberiu PetrescuIn today's mechanical transmissions most widely used, the gears, are spread across all industries. For this reason, their importance has become overwhelming, which is why we want to recall in this paper some important aspects regarding toothed wheels. It is the geometry, cinematic, the forces and the yields of these mechanisms, which will be presented in the work in the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 7,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Model for GearsAversa Raffaella, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuNearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 10 May 2017 · 7,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Clustering Based Genetic Algorithm for Solving Complex NP ProblemsR. Sivaraj, T. RavichandranProblem statement: The selection process is a major factor in genetic algorithm which determines the optimality of solution for a complex problem. The selection pressure is the critical step which finds out the best individuals in the entire population for further genetic operators. The proposed algorithm tries to find out the best individuals with reduced selection pressure than standard genetic … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractSocial-economic and Ecological Criteria of Noise ControlM. A. Al-NawaflehWhen designing new and/or modifying pre-existing equipment, the problem of economic feasibility is always of prime importance . However, the economic feasibility is often a matter of discussion in various social aspect. To operate no aesthetic, noisy, dusty, gazed heavy machine with large number of visually fixed moving parts and gearing, it is often dangerous and even risky. The work … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,676 accessesView PDFCite
