【 摘 要 】

The paper deals with the issues of increasing the continuous mixers efficiency. The solution to this problem is known to be possible both by increasing the volume of the working chamber and by increasing the velocity characteristics of the work member. Consequently, there is a need to investigate continuous mixers with an oscillation mechanism. The article presents the calculation scheme of the continuous mixer as well as the algorithm of the mixer kinematic parameters calculation considering the reciprocating movement of the work members. We obtained the graphical dependence of the working shafts path, velocity and acceleration in the axial direction on the eccentric rotation angle as a result of mathematical modeling of these parameters. The work provides the dependence of the axial velocity and acceleration on the axial and tangential velocities ratio, as well as the dependence of tangential and axial load on the blade fitting angle for some values of the axial and tangential velocities ratio. We prove that with the increase in the blade rotation angle the axial loading increases, while tangential load decreases, thus the constant value of the resultant force remains constant within the specified interval of values. The increase in the velocities ratio leads to the increase in tangential load and reduction of axial load, which should be taken into account in the synthesis of a new mechanism.
