The invention relates to the technical means used to solve research problems arising from the study and development of the ocean. It can be used to create sealed containers immersed to different depths, mainly for hydrophysical instruments.

The purpose of the invention is to increase the reliability of the joint by eliminating the extrusion of lubricant and reducing frictional forces in the interface area of the support surfaces of the ring-frames.

Figure 1 shows the diagram of the housing of a hydrophysical instrument made of two spherocylindrical shells; on

In an example of a specific embodiment, a method is described for the manufacture of a razmez assembly of a hydrophysical instrument body designed to operate at an external hydrostatic pressure in the order of 100-120 MPa.

The housing of a hydrophysical instrument (Fig.) Contains two monolithic axisymmetric cylindrical shells with hemispherical bottoms 1 of average thickness (thickness to sheath radius 0.11-0 35) made of glass glass M KR-1. Shells 1 are interconnected through a connector assembly, which

includes framing rings 2, made of hardened steel 12X18H10T, mounted on the ends of shells 1.

shells 1 (see Fig. 2} are inserted into framing rings 2 and secured with epoxy adhesive D-9. A micro-relief is used to hold graphite (solid lubricant) on the support surfaces of the framing rings (see fig. 3). of the tracks of the frame 2 are made conical. The tapers of the supporting mating surfaces of the reaming rings 2 are smooth between themselves, the tops of the cones are directed to the same / side, the body lies on the longitudinal axis, and the angle at the top of each cone is 145 °

The design of the crocodile containment contains a clamping ring, four studs and nuts, a bandage from the first window on the ruin of the assembly and element, intended for assembly and ipp of the housing after placing the device on it (and the figures are not shown ) For ease of use, the case is placed v protective of the floor of the notes and foam perforated with holes (not shown in the figures)

Mortise grinding (sanding with cross-feeding) performed as follows: a) the ring-frame was drank in a strictly defined position of the device installed on the cra.-fj e VYA-139, which provides the orientation of the ring-frame and movement during grinding; b) grinding carried out and using two movements - npaiuc, - neither the machine spindle and the feed movement to the grinding wheel, which is achieved by blowing a high-speed pneumatic actuator; c) the circumferential speed of the circle is 13-15 m / s.

At the same time, in the first stage - the stage of mortise grinding, the same equipment is used as in the case of mortise grinding of conical surfaces, the direction of grinding is no tangent to the inner circumference of the ring in one direction, grinding modes (for the same material of the ring) also remain the same . The second stage, the flat grinding stage, is carried out on a planar / foveal machine (for example, ZB722). Mortise grinding on the specified machine to obtain a given direction of asperities is technologically difficult to implement. Therefore, different equipment is used at each grinding stage.

The grinding operation is carried out in two stages: preliminarily according to the technology of mortise grinding, a microrelief is formed on the supporting surfaces of the framing track to retain solid lubricant — graphite, then using the cr / deep or flat grinding technology, depending on the type of mating surfaces, reduce the surface roughness to a predetermined, then rubbed fine graphite powder from the grinding surface,

Grinding of the support surfaces of the ring frames using the mortise grinding method is carried out on lines whose projections onto the plane of the inner circumference of the grinding frame & sun-tangent straight lines to the circle in one direction. Microrelief on each support

the surfaces are mirrored in relation to the microrelief pattern on the opposite support surface, which helps reduce friction by keeping graphite films under load

and eliminate the extrusion of lubricant during the operation of the connector assembly,

Grinding in two stages is due to the fact that high purity is high during mortise (deep) grinding.

The surface is difficult to reach. The roughness of the surface treated with diamond circles is actually possible, but it can be higher than R a 0.82 microns. Optimal support roughness

The surfaces of the ring frames to avoid extrusion of graphite are roughness Ra 0.32-0.63 microns. Therefore, grinding is carried out in two stages - mortise to Ra 1.0-0.82 µm, and then

either flat or round to a roughness of R- 0.32-0.63 microns.
