CONTRIBUTION TO THE DYNAMIC STUDY OF THE MILL WITH HORIZONTAL AXIS. PART I: PRELIMINARY STUDY

Alexandra Maria MACOVEI, Mariana ARGHIR

Abstract


The work is part of a group of three works, in which the dynamics of a fodder grain mill, equipped with a horizontal shaft, which is directly welded on the shaft of the electric motor drive are studied. In the first part, the components of the dynamic system are established, for which the geometric dimensions are known, the connection relationships between the component elements, as well as the masses in the system and the mechanical system is prepared to obtain the mechanical scheme.


Key words: mill with horizontal axis, preliminary study of the mill dynamics
