EXPERIMENTAL RESEARCH OF THE IMPACT OF ANGLES OF THE TANO ROLLER TANING ON THE ROUGHNESS OF THE BRAIDED SURFACE
Work belongs to technology of processing of external cylindrical surfaces superficial plastic deformation. The size of slipping of a conic roller when rolling the cylindrical samples made of steel 35 and 45 is investigated. The scheme for determination of size of slipping when processing a detail by superficial plastic deformation, and also the site of a chart tape with record of a signal on which calculation of the impulses arriving from the probes adjoining to surfaces of a roller and the detail carried to a certain length of record was made is provided. The size of depth of introduction of the deforming roller in preparation, and its influence on roughness of the processed surface is determined. Results of pilot studies are presented in the form of schedules of dependences of change of slipping on the angles of self-tightening and introduction, roughness from depth of introduction, the angles of introduction and self-tightening. It is shown that deformation force practically does not change at the angles of self-tightening which are ranging from 0 up to 3 degrees therefore it is possible to explain reduction of roughness of a surface of the processed samples existence of slipping of the adjoining surfaces to the rolled details and the deforming roller. It is also established that if to establish a conic roller by the smaller basis in the direction of giving, then the roughness decreases in comparison with installation of the same deforming element the same basis in the direction opposite to the direction of giving a little.
