Abstract

Periodical mixers are considered. The expediency of developing a new type of mixer is presented. Features of the material movement in the mixer allow to speak about the presence of elements of a gyroscopic effect. The mixing chamber is rotated by means of belt, chain and conical transmission. The resulting complex spatial movement of material particles can be controlled by a frequency Converter and the selection of appropriate gears or using a belt drive. An algorithm for modeling the drive unit of a mixer with a bidirectional rotational effect on the material is presented. The features of the drive unit and its components are considered. The task is to build a model of deformation of the drive unit of the mixer. The finite element method (FEM) for the drive unit of the mixer is used. Machine experiments are performed that implement fatigue calculations of the drive unit with a study in the SolidWorks Simulation environment. The results of static analysis of the drive unit operation in determining the deformation, static analysis of the drive unit operation in determining the voltage with varying torque are obtained. A variant of static analysis is presented when using a belt drive instead of a gear drive. The practical implementation of the mixer drive unit in metal is shown. Conclusions on modeling are made.
