Abstract

The invention relates to the treatment of metals by surface deformation and can be used in mechanical engineering to create the optimum. operating conditions of rubbing steam. The purpose of the invention is to increase technological capabilities by obtaining on the surface to be treated areas with different depths of oil pockets. To achieve the goal, the device is equipped with a micrometer screw mounted inside the axis of the roller with an eccentrically shaped cylindrical end, kinematically connected to the indenters by means of a moving frame. When the micrometer screw rotates, the movable frame moves the indenters in the radial direction relative to the working surface of the deforming element. 3 il.

Description

The invention relates to the treatment of metals by surface formation and can be used to create optimal operating conditions for the friction pairs.

The aim of the invention is the expansion of technological capabilities through the production of oil pockets of various depths.

This goal is achieved by the fact that the rolling device, which includes a holder and an axis-mounted deforming roller with embedded indenters, is equipped with a micrometer screw installed in the axis of the roller with an eccentrically made cylindrical end, kinematically connected to the indenters by means of a moving frame.

Supplying the axis of the roller with a micrometer screw with an eccentric cylindrical end allows the indenter to be advanced to a greater or lesser height relative to the surface of the roller, which makes it possible to vary the depth of the pockets formed and thus expand the technological capabilities of the device.

FIG. 1 shows the proposed device in section; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG.

The proposed device (Fig. 1) contains a holder 1, a deforming roller 2 with indenters 3 embedded in it and an axis 4. For machining the surfaces of the holes, the holder 1 is made at an angle of 90 (shown in Fig. 1 with a dot-dash line). The roller 2 is fixed on the disks 5 and 6, which rest on the sleeves 7 and 8 mounted on the axis 4,

A micrometer screw 9 is screwed into the hole of axis 4, having an eccentrically shaped cylindrical end on which the finger 10 rests in contact with the moving frame 11 The spring 12 serves to ensure constant contact of the frame 11 with the finger 10.

A ring 13 is mounted on the frame 11 and serves as a support for the inductors 3. The indenters 3 are prevented from falling out by an elastic gasket 14 which is put on the ring 13.

The cover 15, which protects the axis 4 from turning, is secured to the support 1 with screws 16.

g The device operates as follows.

The toolholder 1 is fixed, for example, in the tool holder of a turning screw cutter. Warp roller 2

10 is pressed against the workpiece surface.

When turning on the rotation of the part and the movement of the feeding device, roller 2 begins to rotate due to tension

15 between it and the workpiece surface. Indenters 3 form a helix of microprints on the part surface.

With the rotation of the micrometric.

The 20 screw 9 changes the position of its eccentrically formed cylindrical end and the magnitude of the eccentricity in the radial direction varies from O to e.

25 Based on the screw 9, the finger 10 is moved in the radial direction; SRIs, as a result of which frame 11 with a ring 13 and indenters 3 change their position. This allows you to push

30 indenters 3 to a greater or lesser height relative to the surface of roller 2 and thus to obtain on the treated surface areas with different depths of oily micro-pockets.

The proposed device allows to obtain pockets of different configurations on the surface to be treated, depending on the shape of the indenters, and

40 also depths depending on the operating conditions of the mating surfaces, which ensures their uniform wear over the entire surface of the friction. Invention Formula 45 A rolling device comprising a holder with a deforming element and indenters installed inside the latter, characterized in that, in order to expand 50 technological capabilities due to oil pockets of various depths, it is equipped with an adjusting mechanism made in the form of a frame and a micrometric screw with an eccentric cylindrical end, the frame being installed coaxially to the deforming element between the indenters with the possibility of contact with the latter. 35 15 16 1 6-5 FIG. 2 Compiled by S.
