Research ArticleOpen accessEvery word in the titleAbout the Gear Efficiency to a Simple Planetary TrainRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion T. PetrescuSynthesis of classical planetary mechanisms is usually based on kinematic relations, considering the achieved transmission ratio input-output. The planetary mechanisms are less synthesized based on their mechanical efficiency which is developed during operation, although this criterion is part of the real dynamics of mechanisms and also the most important criterion in terms of performance of a mechanism. Even when the … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 23 Dec 2016 · 8,815 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPresentation of Four-stroke Engine Design ElementsRelly Victoria Virgil PetrescuHaving escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Apr 2020 · 6,955 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordGears-Part IRelly Victoria V. Petrescu, Raffaella Aversa, Bilal Akash et al.The gears are today the most widespread and most frequently used mechanical transmissions, all over the world. They must be the factory on an industrial scale, everywhere and have a variety of uses, being extremely important for both the heavy machines of industrial buildings, as well as for domestic appliances, electronics, etc. meet the excessive size normal, big or even … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 10 May 2017 · 8,210 accessesView PDF Cite
