Item type:Item, Механічна модель рихлення грунту(КНТУ, 2013) Герук, С. М.; Geruk, StanislavНа основі загальної теорії гвинтових поверхонь отримані математичні залежності робочих поверхонь ножів, їх просторові силові та кінематичні параметри, формули для розрахунку швидкості та прискорення. The purpose of research. Getting dependencies for performing power analysis and construction of mechanical-mathematical model of soil particles by rotating rough plane rotates around a horizontal axis and is inclined to it at an arbitrary angle. Results. The technological process of the formation of the chip, its rotation and styling when using a knife, which is mounted in the plane of the ellipse, which is inclined at an arbitrary angle to the horizontal axis and rotates at a preset speed around it. Designed force and kinematics. Based on the general theory of helical surfaces obtained mathematical work surfaces depending knives, their power and spatial kinematic parameters of the formula to calculate the speed and acceleration. Conclusions. Determination of the absolute velocity will help to justify the feasibility of parameters and operating modes of the rotary tillage machines hosted on the proposed scheme.Item type:Item, Визначення циркуляції вороху у молотарці зернозбирального комбайна(КНТУ, 2013) Герук, С. М.; Пустовіт, С. В.; Geruk, Stanislav; Pustovit, S.Викладено методику визначення закономірності циркуляції колосового вороху в молотарці комбайна, яка проводилась на експериментальній установці. Описано спосіб забарвлення насіння для визначення циркуляційних процесів.The determination methods of regularity of the ear heap circulation, which were held at the experimental laboratory plant, are explained. The way of the seed colouring for circulation processes determination is described. Conformity to law of circulation lots in the threshing machine of combine can be studied during work of row of the parallell set cleanings with a transmission ear lots to every following from them.The purpose of work is a search of ways of effective decline of injuring of grain at collection, research of process of circulation and separacii of components ear lots. Geared-up thus grain was used for a study conformity to law of circulation lots in the threshing machine of combine and its influence on the indexes of work of cleaning. For this purpose by us was the developed and made setting, that allows to define the size of the circulatory loading during three cycles.
