Теоретическое определение коэффициента полезного действия (КПД) планетарных передач на стадии проектирования при заданном передаточном отношении позволяет сравнить различные схемы передач и выбрать наиболее рациональную, обеспечивающую необходимые кинематические характеристики и минимальные потери мощности. В работе рассматриваются вопросы теоретического определения КПД планетарных передач для электромеханических систем с распределенными параметрами при известной кинематической схеме, для установленных ведущих и ведомых звеньев, а также известным КПД зацепления реверсивного механизма. Представлен всесторонний анализ алгоритмов, разработанных для теоретической оценки КПД планетарных передач. Метод. Представлены инструменты для более точного и универсального определения КПД планетарных передач. Разработаны алгоритмы для теоретического определения КПД планетарных передач на стадии проектирования. Предложены две универсальные зависимости, которые позволяют оценить энергоэффективность различных кинематических схем планетарных передач, учитывая функции ведущего и ведомого звеньев. Основные результаты. Показано, что в планетарных передачах с ведущим водилом при выборе кинематической схемы и чисел зубьев колес для обеспечения заданного передаточного отношения необходимо стремиться к его положительному значению, что при равных условиях обеспечивает более высокий КПД и меньшую нагрузку на корпус редуктора. Для циклоидально-цевочных передач с двухвенцовым сателлитом с циклоидальным профилем зубьев центральное колесо, закрепляемое в корпусе, должно иметь большее число цевок, чем центральное колесо, устанавливаемое на ведомом валу. Метод применим для планетарных зубчатых и циклоидально-цевочных передач, работающих в редукторном и мультипликаторном режимах. Обсуждение. Полученные результаты вносят вклад в оптимизацию конструкции зубчатых передач, способствуют повышению энергосбережения и улучшению механического КПД в различных областях применения.</p></abstract><trans-abstract xml:lang="en"><p>Theoretical determination of planetary gear efficiency at design stage for given gear ratio allows for comparison of various designs and selection of most efficient one, providing required kinematic characteristics and minimal power losses. This article examines theoretical determination of planetary gear efficiency for electromechanical systems with distributed parameters for given kinematic design for installed driving and driven links as well as known engagement efficiency of reversing mechanism. Comprehensive analysis of algorithms developed for theoretically estimating planetary gear efficiency is presented. These systems are considered within framework of specific kinematic designs where both driving and driven links are clearly defined, and known engagement efficiency of reversing mechanism is taken into account. Main objective is to provide tools for more accurate and universal determination of planetary gear efficiency. Algorithms for theoretical determination of planetary gear efficiency are developed. Two universal relationships are proposed that allow for estimating energy efficiency of various planetary gear kinematic designs, taking into account functions of driving and driven links. Method enables theoretical evaluation of efficiency at design stage. It is shown that in planetary gearboxes with leading carrier, when selecting kinematic design and gear tooth count to ensure given gear ratio, it is necessary to strive for positive gear ratio. This, all other things being equal, ensures higher efficiency and lower load on gearbox housing. For cycloidal-pinion gearboxes with two-crown satellite with cycloidal tooth profile, central gear, secured in housing, must have greater number of pinions than central gear mounted on driven shaft. Method is applicable to planetary gearboxes and cycloidal-pinion gearboxes operating in reduction and multiplier modes. Obtained results contribute to optimization of gearbox designs and contribute to increased energy savings and improved mechanical efficiency in various applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>планетарная передача</kwd><kwd>редуктор</kwd><kwd>множитель</kwd><kwd>КПД</kwd><kwd>носитель</kwd><kwd>сателлит</kwd><kwd>передаточное число</kwd><kwd>электромеханическая система</kwd><kwd>распределенные параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>planetary gear</kwd><kwd>reduction gear</kwd><kwd>multiplier</kwd><kwd>efficiency</kwd><kwd>carrier</kwd><kwd>satellite</kwd><kwd>gear ratio</kwd><kwd>electromechanical system</kwd><kwd>distributed parameters</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы благодарят сотрудников учреждений, внесших свой вклад в настоящее исследование, включая академические учреждения и коллег, предоставивших ценные сведения.
