The oretical analysis of the interaction of discrete drum with head teeth with fiber

Аннотация

The article is based on the analysis of the conditions of fiber retention with the teeth of a discrete drum saw gear pneumatic spinning machine, to determine the angle of inclination of the heads saw teeth, the change in drum speed, the force of gravity on the front end of the tooth, the coefficient of friction The equations of dependence on the mass are obtained and the analytical expressions of the law of motion of the fiber on the tooth surface of the discrete drum headset are given. As a result of the analysis of fiber tension and velocity, theoretical analyzes and graphs are presented to determine the increase in tensile strength and velocity of a fiber with an increase in the sampling zone.
