Among filtering techniques most often used for retention of particles in gases resulting from various industrial activities, an important place is taken precipitatoarele electrostatic (also called filters or electrostatic electrofiltre). These facilities are based on filtering the loading operation of electrical load with particles so that they can be retained. Under the electric field, the particles collected are deposited on surfaces of electrodes collection. From the mass of particles collected precipitatoarele ensure efficiency electrostatic filter higher percentage of 99%. Another big advantage of these filters is that they can handle very large flows of gas, while causing loss of pressure in very small installations of their evacuation.

The loading of the shaft of a driving drum of a belt conveyer with a two-drum drive and cantilever (pendel) joining of the motor-reducer group has been studied. In addition to the distribution of deformations and tensions, the force reactions in the bearings of the shaft and the joints of the motor-reduction group with the frame of the driving station have also been analyzed. A principal scheme of a mechanical compensator for reducing the force reaction, which loads the spherical bearings in the bearings of the shaft, has been suggested.
