Исследуется изменение несущей способности подшипника, максимальной температуры смаз­ки и потерь мощности при изменении частоты вращения упорного диска ротора. Обнаружен скачок несущей способности и потерь мощности в первых секундах разгона упорного диска и низкой вязкости смазки при температуре подачи. Исследовано изменение несущей способно­сти упорного подшипника при одновременном выбеге ротора и непрерывном мягком помпаже центробежного компрессора. Отмечено возникновение некоторого разрежения на рабочей по­верхности подушки при остановке и продолжающемся гармоническом осевом перемещении упорного диска.</p></abstract><trans-abstract xml:lang="en"><p>The article presents numerical studies of the effect of transient modes of operation of a fixed pad thrust bearing of a centrifugal or screw compressor. The change in the bearing capacity, maximum lubricant temperature and power losses with a change in the rotational speed of the rotor collar is investigated. A jump in the bearing capacity and power losses in the first seconds of acceleration of the collar and low viscosity of the lubricant at the feed temperature is detected. The change in the bearing capacity of the thrust bearing with simultaneous rotor runout and continuous surge of the centrifugal compressor is studied. The occurrence of some vacuum on the working surface of the pad during stop and continued harmonic axial movement of the collar is noted.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компрессор</kwd><kwd>упорный подшипник</kwd><kwd>переходный режим</kwd><kwd>помпаж</kwd><kwd>частота враще­ния</kwd><kwd>несущая способность</kwd><kwd>максимальная температура</kwd><kwd>потери мощности.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>compressor</kwd><kwd>thrust bearing</kwd><kwd>transient mode</kwd><kwd>surge</kwd><kwd>rotational speed</kwd><kwd>bearing capacity</kwd><kwd>maximum temperature</kwd><kwd>power losses.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Хисамеев И.
