The disadvantage of this design is the impossibility of creating a return-and-forward movement of the tool in the radial direction without a special device and the impossibility of one-time processing of two eccentric cylindrical noises with one roller.

The aim of the invention is to create a tool without a special device to form the reciprocating dosing of the working tool in the radial direction; directions when processing eccentric

but arranged cylindrical surfaces.,. . .. ,,. .

The goal is achieved by the fact that the roller is equipped with at least two working surfaces made eccentrically relative to each other, and the magnitude of this eccentricity exceeds the active surface of the surface.

0 1.5-3 times.

Such a runner operation provides a significant increase in the intensity of smoothing and the depth of propagation of plastic deformation during chip and hardening processing and the possibility of simultaneous processing of two extra-spaced surfaces with one roller,

FIG. 1 shows a general view.

0 tools for oiSrabotka two eccentric located cylindrical surfaces; ya fig. 2–4 are the positions of the working surfaces of the roller when rolling in two 3KcifeHTpH4H6 located 5 cylindrical surfaces; in fig. 5 is a diagram of the contacting of the working surfaces of the roller with two eccentrically arranged surfaces in cross section.

0 - Insulation; p1 of the surface hardening of the part contains roller 1 (Fig.), Which has two working surfaces 2 and 3 of different diameters, corresponding to the diameters of the surfaces being rolled. These. The working surfaces of roller I are made one relative to the other with eccentricity ЕР, moreover, the value of eccentricity ep is greater than the eccentricity of the surfaces of the workpiece en- 1.5, ... 3.0 times, with the ratio of the diameters of the part and the roller providing the greatest effect It is from 5 to 21. The roller 1 is installed in bearings 4 on axis 5, fixed in fork 6 with a shank, which is installed in housing 7. To regulate the rolling force, a spindle 8 and an adjusting nut 9 are provided. Whoever is one, then another surface of the roller (Fig, 2 3.4). Initially, the small diameter surface of the roller 1 is in contact with the surface being rolled, and the larger working diameter surface 3 does not touch the shell of the washable part (Fig. 2 When the roller 1 turns on the angle EO with respect to the initial position, both working surfaces 2 are in contact and 3 (Fig. 3). When the roller is rotated through an angle of 180 ° with respect to the initial position, the working surface 3 of larger diameter and the small diameter surface 2 does not touch it, (Fig. 4). When the angle is but there will be 270 ° f in contact with the surface being rolled around, both working surfaces of optical drive 1 (Fig. 3) will again be found, and when the roller is rotated 360 times, it will be a full turn, in contact with the treated surface, again, there will be a working surface 2 of smaller diameter Roller 1 (Fig. 2). The entire cycle is then repeated. Fig. 5 shows cross sections of contact areas for eccentrically run around, large and small diameter surfaces with working surfaces on 1 roller, when the diameters of the roller are significantly smaller than diameters etrov obkatyvali surfaces. Section 10 corresponds to the position shown in FIG. 2 contacts of rolling face with surface 2 of small diameter of roller 1. Section 11 corresponds to the position shown in FIG. 3 contacts roll around the 5th surface with the working surfaces 2 and 3 of the roller 1, Section .12 corresponds to the position shown in FIG. 4 contacts of the rolled surface with the working surface 3 of larger diameter of the roller 1, etc. Such crushing of the rolling surface into areas, the additional impact of the working surfaces of the roller on the rolling surfaces allows a significant increase in the smoothing intensity, the depth of plastic deformation of the metal. In this case, the process of simultaneously rolling two eccentrically arranged cylindrical surfaces with one roll-on roller is provided. The diameters of the working surfaces of the roller are not multiples of the diameters of the workpiece being rolled, the entire surface of the roller will be processed completely in a few turns due to the displacement and the contact areas. Formula of the invention A tool for finishing and hardening the surface treatment of parts containing a roller located in bearings on an axis fixed in a fork-shaped holder elastically installed in the housing, so that with the aim of simultaneous processing two eccentrically located surfaces, roller. it is provided with at least two working surfaces made eccentrically relative to each other, moreover, the magnitude of this eccentricity exceeds the eccentricity of the surface. surface 1.5-3 times.
