Parameters of technological machine roll contact curves

Abstract

The main parameters of the contact curve of each roll are its shape and length, and the extent of the slip and no-slip zones. Analytical dependencies were obtained that determine the parameters of the contact curves of the rolls of technological machines. It was revealed that at the beginning of the contact zone the skin points are distant from the roll covering point, in the zone at the end of the contact zone it is ahead of it. At the end of the contact zone, the angle between the corresponding points of the skin layer and the roller coating is equal to the modulus of the difference between the lag and advance angles.
