CERCETĂRI ÎN SCOPUL REALIZĂRII DE TRANSMISII MECANICE DE PUTERE ŞI DE TURAŢIE RIDICATĂ, ÎN CONDIŢIILE OPTIMIZĂRII DIN PUNCT DE VEDERE TEHNICO-FUNCŢIONAL ÎN RAPORT CU TRANSMISIILE MECANICE DE UZ

摘要

The research works foccused on the optimizing of the mechanical transmissions have as main objectives the extension of the operating range and the increase of the reliability degree of these transmissions. More exactly, the extension of the operating range is made by the extension of the range of transmission ratios. Actually, the extension of the range of transmission ratios was obtained using power and by using highly speed and torques.To increase the reliability degree of the mechanical transmissions and to reduce the material consumption, there were used constructive solutions as compact as possible and materials with physico-chemical characteristics suitable to critical operating conditions. Therefor, execution technologies suitable to the imposed precision class were adopted and, consequently, there were performed mechanical transmissions of most silent operating.%Lucrarea de cercetare are ca scop optimizarea transmisiilor mecanice, având ca obiectiv principal extinderea domeniului de funcţionare şi creşterea gradului de fiabilitate a acestora. Mai exact, extinderea domeniului de funcţionare se bazează pe extinderea rapoartelor de transmisie, în prezent, extinderea domeniului rapoartelor de transmitere a fost obţinut utilizând puteri, turaţii şi momente ridicate.
