The article covers the results of research on substantiation of the parameters of the modernized cotton bundle disassembler machine with the working drum with a curved peg and a flexible element. The design scheme and working principle of the machine are described. Recommended values of the parameters because of full factor experiments in the production environment are given. The results of the calculations after processing in the article are presented in the form of connection graphs for raw cotton. In each graph, the first factor is presented at the minimum, the second at the intermediate, and the third at the maximum value. The figures show graphs of the dependence of the seed damage after the UHK unit on the input factors and the graphs of the dependence of the torque on the milling shaft on the input factors.

The article covers the dynamics of the machine aggregate with a milling mechanism of the cotton bundle disassembler, taking into account the mechanical characteristics of the electric drive, technological resistance and torque of friction forces. The law of motion of the milling machine is defined. The dependence of the torque coefficient of the rubber bushing mounted on the milling heads on the vibrational value of the angular velocities of the rotating drive drum, the angular velocity of the drive rotor and torque is shown. Optimal values of the parameters according to the analysis of the connection graphs were recommended.
