Основные достоинства винтовых компрессоров «сухого» сжатия по сравнению с маслозаполненными компрессорами — их компактность ввиду отсутствия развитой системы смазки с громоздкой системой маслоотделения, а также дополнительных фильтров; экологичность; экономия обслуживания. Одним из направлений повышения объемных и энергетических характеристик винтового компрессора является совершенствование методики расчета профильных зазоров путем учета различных факторов, возникающих при его работе. С учетом того, что винтовой компрессор «сухого» сжатия зачастую работает на режимах с повышенными значениями температур сжимаемого газа, существенно увеличивается тепловая загруженность элементов компрессора по сравнению с маслозаполненными компрессорами. Таким образом, при расчете зазоров необходимо учитывать тепловое состояние роторов, а также распределение температур по роторам в рабочих полостях. В статье предложена методика расчета температурных полей роторов с целью уменьшения профильных зазоров роторов и улучшения характеристик винтовых компрессоров «сухого» сжатия.  </p></abstract><trans-abstract xml:lang="en"><p>In case of the wildly using of screw compressors in modern industries, the compressor efficiency improving methods’ development are actual. The main advance of the «dry» screw compressor comparing with oilinjected compressors is their compact due to the no needs huge oil system, which includes oil separation system and additional filters, which leads to improving an ecology and reducing the exploitation coast. One of the way of the compressor capacity and energy efficiency improving is developing of the rotor profile gaps’ calculation methodic by taken into account different factors determined by the compressor working conditions. The heating load on the «dry» screw compressor parts higher than on the oil-injected compressor parts, because their working conditions lead to the highest value of the discharge temperature. Therefore, it is necessary to take into account compressor rotors’ temperature fields to calculate rotors’ profile gaps correctly. This paper presents the methodic of the rotors’ temperature field calculation with the aim to reduce the rotors’ profile gaps and improve the «dry» screw compressor efficiency.  </p></trans-abstract><kwd-group xml:lang="ru"><kwd>винтовой компрессор «сухого» сжатия</kwd><kwd>профильные зазоры</kwd><kwd>тепловые деформации</kwd><kwd>тепловые поля</kwd><kwd>теплообмен в рабочей полости</kwd><kwd>теплота трения роторов о рабочее тело</kwd></kwd-group><kwd-group xml:lang="en"><kwd>«dry» screw compressor</kwd><kwd>profile gaps</kwd><kwd>temperature fields</kwd><kwd>temperature deformation</kwd><kwd>heat exchanging process inside working chambers</kwd><kwd>friction heating between the gas and rotors</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">Burckney D., Kovacevic A., Stosic N.
