dc.description.abstract Sound measurement and analysis are required to determine what sound is typically generated and what sound is undesired noise. This analysis is accomplished by the use of a sound analyzer. A sound analyzer is an instrument which displays sound waves in the rms levels at various frequencies or frequency bands. Using an analyzer will help separate undesired frequencies from the sound spectrum and contribute to an accurate interpretation of sound data. The sounds generated during gear unit operation can be from one or more of the following major sources: gear dynamics; bearing dynamics; coupling noises; system resonance or critical speeds; accessories such as funs, lubrication systems, etc. en_US
dc.description.abstract Măsurarea și analiza sunetului sunt necesare pentru a determina nivelul tipic al sunetului generat în timpul lucrului de transmisiile mecanice. Această analiză este realizată prin utilizarea unui analizor de sunet. Analizorul de sunet este un instrument care afișează undele sonore în nivelurile RMS la diferite frecvențe sau benzi de frecvențe. Analizorul permite separarea frecvențelor nedorite de la spectrul de sunet și de a contribui la o interpretare corectă a datelor de sunet. Sunetele generate în timpul funcționării angrenajului pot fi de la una sau mai multe din următoarele surse principale: dinamica angrenării, dinamica rulmenţilor, zgomote de cuplare, rezonanță de sistem sau viteze critice, accesorii, cum ar fi sisteme de ungere, etc. ro
dc.description.abstract Analyse et mesure de niveau sonore sont nécessaires pour déterminer le bruit généré pendant le fonctionnement des systèmes mécaniques. L'analyseur est une mesure utile qui affiche des signaux dans le spectre de fréquence. Avec l'analyseur nous pouvons séparer les fréquences indésirables du spectre sonore avec précision pour interpréter les données audio. Les sons qui se produisent pendant les travaux de transmissions mécaniques peuvent être d'une ou plusieurs sources primaires: engrenage; couplage; résonance (vitesse critique systèmes de lubrification, etc. fr
dc.description.abstract Измерение и анализ шума нужен для того чтобы определить типический уровень шума генерируемого во время работы механических устройств. Анализатор шума является инструментом, который отображает звуковые сигналы в частотном спектре. С помощью анализатора можно отделить нежелательные частоты звукового спектра с точностью интерпретировать звуковые данные. Звуки, возникающие во время работы механических трансмиссий, могут быть от одного или нескольких основных источников: зацепление, муфта, резонанс, системы смазки, и т.д. ru
