“…The aim of the study is to determine the rotational speed n of the spindle of the planetary mechanism in the area of collecting and removing raw cotton, since the rotational speed n of the spindle in the area of collecting raw cotton affects the quality of damage to the cotton fiber. The higher the frequency of rotation of the spindle in the zone of harvesting raw cotton, the greater the likelihood of damage to the cotton fiber by the teeth of the spindle, and in the zone of reverse rotation of the satellite 1, the speed parameters of the satellite increase and it is easier to remove the raw cotton from the spindle [13].…”

The article presents the kinematics of the satellite interacting with the flexible links of the belt transmission of the epi and the hypocyclic planetary mechanism of the spindle drive of the vertical-spindle cotton harvester. The frequency rotations in the absolute and relative movement of the satellite in both zones are determined in an analytical form: the collection and removal of raw cotton from the spindle. The numerical values of the frequency rotation of the spindle for the first and second speeds of the harvester are obtained. Theoretically and experimentally, a curve is constructed in a linear form, a graph of the patterns of change in the frequency of rotation of the satellite from the number of revolutions of the carrier of the planetary mechanism. The coefficient of elastic sliding of the roller ξ along the belt and the crown block is obtained, which is equal to ξ = 0,07...0,168 and ξ = 0,126...0,138 respectively.

In all cases of designing retaining walls (RS) on roads, their main purpose is to ensure the stability of the roadway. At the same time, special attention is paid to ensuring the stability of the retaining walls themselves, on which the stability of the structure as a whole depends. Therefore, it seems advisable to first determine the area of the roadway within which the roadside walls are guaranteed to be stable against overturning in accordance with the applicable regulations on the road where the retaining walls are to be designed. The article deals with the problem of forming the mentioned zone in the body of the embankment of the road for the optimal placement of reinforced concrete thin-walled retaining walls in it.

The article is devoted to the results of a theoretical and experimental study of forced oscillation of the epi-hypocyclic planetary mechanism synchronizer used to drive the spindles of the cotton machine apparatus. Spectrum of natural oscillation frequency of synchronizer is determined and mass moment of their inertia is set for stability in operating mode when satellite comes in and out of gear engagement of planetary mechanism. Periodic nature of system oscillations under action of external forces of satellite is considered. The graph of oscillations of actual excitation of the synchronizer in the form of a pulse semi-sinusoidal curve is obtained. The beam diagram is built that allows you to make delaminations from the resonant modes of operation of the synchronizer.
