Abstract

The article deals with issues related to the study of planetary machines. It is demonstrated that they are able to significantly intensify most of the processes applicable to them. This is due to the complication of the trajectory of the movement of the working body and the increase in inertial forces. In addition, planetary units are energy efficient. The influence of the mutual action of grinding bodies on their power characteristics in a planetary mill with external and internal running of the drums is presented. The dependence of destructive forces on the angular velocity, the degree of filling of the grinding drums, the geometric ratios of the mill itself is shown. Sufficiently simple dependences have been obtained for calculating the total speed at any point of the planetary working body of the smoothing machine. Their use makes it possible to analyze the change in speed over a wide range, depending on a number of design and technological parameters. The proposed method allows to calculate the speeds of the working bodies that make planetary motion. Using the methods of classical mechanics, using the instantaneous center of velocities, a formula is obtained for calculating the speed at any point of the mixing blade. It is established that the speed of the blade changes in time according to a sinusoidal law. The total power gradually increases with increasing angular velocity. The results obtained in this article can be applied in the design and operation of planetary units.
