MECHANICAL SYSTEM DYNAMICS OF TUMBLING MILL DRIVES UNDER STEADY-STATE OPERATION

In tumbling mill drives, increased dynamic loads may occur in open gearing, which may cause an increase in the vibratory activity of the drive assembly and in dynamic loads in the mechanical drive system as a whole. Today, no adequate method is available for calculating the dynamic loads in the open gearing of tumbling mills. The article is devoted to the development of a method for dynamic load calculation, which takes into account the parameters of the drive system. The authors have proposed a mathematical model and a technique that allows for the identification of dynamic loads from experimental data and controlling the vibratory activity of the mechanical drive system of a tumbling mill at the design stage.
