Increase of Effectiveness and Technological Potentialities of Finishing-Strengthening

Abstract

The paper reports the results of investigations on the increase of effectiveness and productivity of machinery finishing-strengthening. The design search of combined screw rotors with the triangular surface along the perimeter was carried out by methods of descriptive geometry and engineering drawing with the aid of “Compass-3D” program complex. The design and operation principle of equipment on the basis of executive organs as combined screw rotors with the triangular surface along the perimeter are shown by the example of the plant for finishing-cleaning and strengthening. For the development of the procedure for calculation of such equipment there is carried out a theoretical investigation of the motion of parts under machining and particles of working environment in combined screw rotors. In the classification developed of equipment executive organs in the form of combined screw rotors there are presented different forms of their surface along the perimeter.
