Подчеркнули актуальность поиска новых материалов для изготовления отдельных узлов машин, которые по своим характеристикам не будут уступать прототипам. Акцентировали внимание на деталях, работающих в подвижных соединениях, в частности на бронзовых подшипниках скольжения типа «втулка», которые подвержены большим износам и часто нуждаются в замене. Предположили, что изготовление таких деталей из полимеров поможет решить проблему преждевременного выхода из строя узлов машины. (Цель исследования) Сравнить триботехнические свойства опор скольжения культиватора, изготовленных из бронзы и полиамида. (Материалы и методы) Изготовили два образца: один из подшипника скольжения (бронза марки БрО10Ф1) культиватора SunGarden GT10, второй – из прутка полиамида марки ПА-6. Использовали специальное оборудование: рентгенофлуоресцентный спектрометр Thermo Scientific Niton XL3t 900 GOLDD+, трибометр TRB-S-DE Tribometer CSM Instruments. (Результаты и обсуждение) Провели сравнительные триботехнические испытания по схеме «шар – диск». Установили преимущество образца из полиамида перед эталоном из бронзы: по коэффициенту трения – в 4 раза, по интенсивности изнашивания – в 12 раз. (Выводы) Определили, что применение подшипников скольжения из полимеров поможет продлить срок службы сельскохозяйственных культиваторов в 2 раза и повысить эффективность использования в 1,5 раза.</p></abstract><trans-abstract xml:lang="en"><p>Agricultural machinery is stated to break down mainly due to the wear of structural parts. Thus, there is a necessity to apply new materials for manufacturing individual machine units whose characteristics will not be inferior to those of their prototypes. The paper primarily focuses on the components that work in movable joints, in particular, on the sleeve type bronze plain bearings which are exposed to high wear and often need replacing. The use of polymers for manufacturing such parts is supposed to solve the problem of untimely failure of machine components. (Research purpose) To compare the tribotechnical properties of cultivator sliding bearings made of bronze and polyamide. (Materials and methods) Two samples were made: one was made of the sliding bearing (BrO10F1 grade bronze) of the SunGarden GT10 cultivator, the other – of a PA-6 polyamide type rod. Special equipment was used such as: X-ray fluorescence spectrometer Thermo Scientific Niton XL3t 900 GOLDD+, TRB-S-DE Tribometer CSM Instruments. (Results and discussion) Comparative tribotechnical ball-disk tests were carried out. It was found out that polyamide sample has certain advantages over a bronze standard: it has a 4-times better friction coefficient and a 12-times better wear intensity. (Conclusions) It was determined that the use of polymer plain bearings will result in 2 times longer service life of agricultural cultivators and their 1.5 times increased efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>опора скольжения</kwd><kwd>подшипник</kwd><kwd>бронза</kwd><kwd>полиамид</kwd><kwd>триботехника</kwd><kwd>коэффициент трения</kwd><kwd>износостойкость</kwd><kwd>культиватор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sliding bearing</kwd><kwd>bearing</kwd><kwd>bronze</kwd><kwd>polyamide</kwd><kwd>tribotechnics</kwd><kwd>friction coefficient</kwd><kwd>wear resistance</kwd><kwd>cultivator</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">Измайлов А.Ю.
