Зазоры в шарнирах механизма привода снижают надежность работы щековых дробилок. Механизмы для выборки зазоров оснащены упругими пневматическими элементами. Эти пневматические элементы в течение всего цикла работы кривошипно-коромыслового механизма постоянно воздействуют на подвижный корпус с закрепленным на нем антифрикционный вкладышем. Механизмы для выборки зазоров обеспечивают выбор зазора в сочленениях кинематических пар, предотвращают появление дополнительных динамических нагрузок, снижают уровень вибрации механической системы. Экспериментально доказано, что при использовании таких механизмов повышается надежность работы щековых дробилок.</p></abstract><trans-abstract xml:lang="en"><p>The article describes the reason of additional dynamic forces occurrence in course of operation of the lever mechanism of jaw swivel drive with gaps in hinges reducing reliability of jaw crushers operation. Gaps sampling mechanisms are equipped with elastic pneumatic elements. These pneumatic elements throughout the entire cycle of the crank-beam mechanism constantly act on the movable body with an anti-friction liner mounted on it. Mechanisms for gaps sampling provide a choice of the gap in the joints of kinematic pairs, prevent the appearance of additional dynamic loads, and reduce the level of vibration of the mechanical system. It has been experimentally established that usage of such mechanisms increases reliability of jaw crushers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>щековая дробилка</kwd><kwd>надежность</kwd><kwd>шарнир</kwd><kwd>зазор</kwd><kwd>пересопряжение поверхностей</kwd><kwd>дополнительные динамические силы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>jaw crusher</kwd><kwd>reliability</kwd><kwd>hinge</kwd><kwd>gap</kwd><kwd>surface interfacing</kwd><kwd>additional dynamic forces</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">Платов С.И., Кандауров Л.Е., Железков О.С., Терентьев Д.В., Мироненков Е.И.
