“…An analysis of the publications devoted to the study of hydraulic problems of roller pressing [7][8][9][10][11][12][13][14] showed that the existing patterns of change in filtration rates in the pressing area were obtained with the introduction of models of roll devices and materials that do not correspond to the real physical phenomena of roller squeezing. Therefore, they do not provide a possibility to solve problems that allow the revealing of the hydraulic phenomenon of roller squeezing.…”

Analytical dependencies are determined that describe the patterns of change in filtration rates in the squeezing area. It was established that the fluid filtration rate along the abscissa axis at the boundaries of the compression zone is zero, and inside the zone, it takes negative values. It was found that the fluid filtration rates along the ordinate axis are zero at the beginning of the compression zone; they increase to a maximum at a point lying on the line of centers, and in the zone of strain restoration, they depend on the angle that determines the position of the point where the fluid changes direction.

The influence of factors on the width of the roller contact and the specific pressure under roller pressing of leather is analyzed in the article. As a result of experimental studies, the dependences of the width of the contact area and specific pressure on the intensity of the load, velocity, and diameter of the rollers were determined. It was revealed that the parameter of the technological specific pressure on the hide in the contact zone increases with an increase in the intensity of the load, the speed of rolls, the width of the contact area, and a decrease in the radius of rolls. An analytical dependence of the residual moisture content of leather on the specific pressure was determined. It was established that with an increase in specific pressure, the residual moisture content of leather decreases and asymptotically approaches a certain value of the function.

В статье представлено решение основных контактных задач теории валкового отжима кожи. Разработаны математические модели формы кривых контакта валков, напряжений трения и закономерности распределения контактных напряжений по кривым контакта валков. Выявлено, что формы кривых контакта валков двухвалкового модуля не зависят от изменения влажности кожи в зоне контакта валков. Установлено, что модель напряжений трения в двухвалковом модуле отжима кожи не зависит от угла наклона обрабатываемого материала относительно линии центров.
