В статье рассмотрен объект ременной передачи, приводящей в движение все барабаны хлопкоочистительного агрегата УСК, наиболее часто используемого в очистительном цехе хлопкоочистительных предприятий, и теоретически рассчитана усовершенствованная конструкция ременной передачи, состоящая из двух шкивов и ремня. Тяговая мощность ремня и ременной передачи по экспериментальным методам характеризуется зависимостью относительного скольжения ремня и КПД от коэффициента сопротивления передачи. Разработана математическая модель новой конструкции ременной передачи, позволяющая теоретически оценить прочность ремня на растяжение и рациональный режим работы в зоне упругого скольжения, конструкция установлена на оборудовании УСК, расположенном в хлопкоочистительном цехе хлопкоочистительного предприятия, входящего в состав унитарного предприятия «Реал Агро Коттон». Результаты эксперимента были проанализированы.

The article considers the object of belt transmission driving all the drums of the USK cotton[1]cleaning unit, most commonly used in the cleaning shop of cotton-cleaning plants, and theoretically calculates the improved design of belt transmission consisting of two pulleys and a belt. Traction power of belt and belt transmission according to experimental methods is characterized by dependence of belt relative slip and efficiency on transmission resistance coefficient. A mathematical model of new belt transmission design has been developed, which allows theoretical estimating of belt tensile strength and rational operating mode in elastic slipping zone; the design has been installed at the machinery of the cotton-cleaning plant, a part of unitary enterprise “Real Agro Cotton”. The results of the experiment were analyzed.
