Using the developed methodology, the radial force acting on the bearing is calculated for specific examples. As a result, the ratio between the radial force of the bearing and the force acting on the most loaded rolling body is obtained, which differs from the calculation of these bearings accepted in modern practice. It is also shown that this ratio is not constant, but depends on the magnitude of the force acting on the most loaded rolling body and the size of the rings and rolling bodies of the bearing. In this regard the following is proposed, in order to determine the maximum load on the rolling bodies-rollers in the working area of the bearing using the developed methodology, the method of iterations or successive approximations is suggested to be used, the essence of which consists in the initial approximate determination of the force acting on the most loaded rolling body, subsequent determination of the load on the bearing and comparing it with the actual force. By repeating this process many times, it is possible to obtain the maximum force acting on the rolling elements in the working area of the bearing with any degree of accuracy.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Разработана методика определения степени нагруженности тел качения в рабочей зоне роликовых радиальных однорядных подшипников, согласно которой распределение нагрузки между телами качения в рабочей зоне данных подшипников зависит от их расположения в этой зоне и размеров контактной площадки между максимально нагруженным телом качения и наружным кольцом подшипника. Используя разработанную методику, для конкретных примеров выполнен расчет радиальной силы, действующей на подшипник. В результате получено соотношение между радиальной силой подшипника и силой, действующей на наиболее нагруженное тело качения, которое отличается от принятого в современной практике расчета данных подшипников. Показано также, что данное соотношение не является постоянным, а зависит от величины силы, действующей на наиболее нагруженное тело качения, и размеров колец и тел качения подшипника. В этой связи для определения максимальной нагрузки на тела качения-ролики в рабочей зоне подшипника с помощью разработанной методики предлагается использовать метод итераций или последовательных приближений, сущность которого состоит в первоначальном приближенном определении силы, действующей на наиболее нагруженное тело качения, последующем определении нагрузки на подшипник и сравнении ее с действительной силой. Многократно повторяя этот процесс, можно получить максимальную силу, действующую на тела качения в рабочей зоне подшипника с любой степенью точности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>roller radial bearing, rolling elements, half-width of the contact pad, contact stresses</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>роликовый радиальный подшипник</kwd><kwd>тела качения</kwd><kwd>полуширина контактной площадки</kwd><kwd>контактные напряжения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Kirilovskiy VV, Belousov YuV.
