A method has been developed for calculating the design and technological values of a pin flexible coupling with a flexible disk-type element, using the method of central compositional rotatable uniform planning of the second order and the finite-element method for calculating stresses using a computer-aided design system. The analytical dependence of the torque on the PCD (pin (centers of holes for pin) circle diameter) and the width of the flexible element with certain physical and mechanical properties was substantiated, on the basis of which the formula for the total width of the flexible disk-type element was obtained, taking into account the value of the required torque and the given PCD. In order to check the obtained dependence of the nominal torque, an additional study of couplings with the given PCD was carried out at different total width of the flexible element. The implemented research allowed determining the influence of the design characteristic values on the transmitted torque of a pin flexible coupling with a flexible disk-type element. A standard-size range of couplings with certain design and technological values has been proposed.</p></abstract><trans-abstract xml:lang="ru"><p>В процессе работы значительной части современного механического оборудования возникают динамические нагрузки, приводящие к выходу из строя деталей, узлов и механизмов, в связи с чем снижаются его долговечность и эксплуатационная надежность. Разработана методика расчета конструктивно-технологических параметров муфты упругой пальцевой с эластичным элементом дискового типа с использованием метода планирования центрального композиционного ротатабельного униформ-планирования второго порядка и конечно-элементного метода расчета напряжений с применением системы автоматизированного проектирования. Обоснована аналитическая зависимость крутящего момента от диаметра окружности расположения центров пальцев (муфты) и ширины эластичного элемента с определенными физико-механическими свойствами, на основании которой получена формула суммарной ширины эластичного элемента дискового типа с учетом величины требуемого крутящего момента и определенного диаметра окружности расположения центров пальцев (муфты). В целях проверки полученной зависимости номинального момента проведено дополнительное исследование муфт с определенным диаметром окружности расположения центров пальцев (муфты) при различной суммарной ширине эластичного элемента. В результате проведенных исследований определено влияние конструктивных показателей на передаваемый крутящий момент муфты упругой пальцевой с эластичным элементом дискового типа. Предложен типоразмерный ряд муфт с определенными конструктивно-технологическими параметрами.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>механическое оборудование</kwd><kwd>динамические нагрузки</kwd><kwd>муфтовое соединение</kwd><kwd>методика расчета</kwd><kwd>моделирование</kwd><kwd>метод конечных элементов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical equipment</kwd><kwd>dynamic loads</kwd><kwd>coupling connection</kwd><kwd>calculation method</kwd><kwd>simulation</kwd><kwd>finite-element method</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">Ruina A., Pratap R.
