Research of the rotation frequency of the working parts of an auger cleaner

The paper presents the results of a study of the working parts of a screw intended for transportation, drying, and cleaning of raw cotton at high productivity. The problem of the dynamics of a machine unit with a mechanism of camshafts in distribution devices of raw cotton during their storage has been solved and an analytical form of the law of changes in the technological load on the camshafts has been obtained, taking into account the results of experimental studies. An oscillogram of the camshaft at idle speed was experimentally obtained. Using the calibration of the measuring channel and the calibration coefficient was determined from the calibration graph, also used the fast Fourier transform method and converted the resulting amplitude value into current units of “ampere”, changes in the power of the electric motor of the shaft, cam, and screw for idle speed were obtained in the form of a graph and the value was determined torque of the electric motor equal to M e =0.91 N·m.
