Description

The invention relates to the field of engineering, in particular to elastic structural elements for connecting spatially movable links, for example, rotary nozzles.

Known elastic joint according to US Pat. RU No. 123079, IPC F16C 7/00 (2006.01) for a utility model containing alternating layers of elastomer and reinforcing plates installed between supporting structural members at the place of use of the hinge.

Known flexible support joint according to US Pat. RU No. 2540356, IPC F16C 7/00 (2006.01), also containing alternating layers of elastomer and reinforcing plates installed between the supporting structural elements. It reinforcing plates made of a composite material based on carbon fabric. They are in a package with layers of elastomer provide stability and the necessary shear strength of the joint as a whole.

Known elastic support hinge according to the application RU No. 20111139332, IPC B64D 27/00 (2006.01), also consisting of alternating rigid plates and elastic layers, providing their shear mobility. The invention also relates to a method for testing elastic support joints of this design.

From the analysis of the considered patent sources, it follows that all the hinges of the rotary nozzles are structurally a set of rigid plates alternating with layers of elastomers, which in total provide the shear deformation necessary for the rotation of the nozzle and require great effort to rotate the nozzle, and are basic in principle.

The objective of the invention is the creation of a hinge for connecting parts of structures with the possibility of relative movement, the principle of which is not associated with shear deformations of the material, and the method of its manufacture.

The essential features of the design of the suspension hinge in terms of eliminating shear deformations in the material during its operation are:

- the implementation of the elastic part of it from woven and winding filament layers with their tight placement, formed around the fastening elements located in one or different planes;

- the implementation of the fastening elements themselves with the inclusion in their design of force rings with kink around them of the same threads of the elastic part.

Salient features of a manufacturing method for a hinge are:

- conducting preliminary manufacturing of the structural and technological frame from, for example, a woven sleeve with metal rings placed in it along the width with the connection of their ends, for example, by welding and the ends of the sleeve, for example, gluing with firmware;

- maintaining the winding of the obtained frame with the estimated number of threads, followed by flashing the elastic part and impregnating the entire hinge with silicone.

The proposed design of the hinge and the method of its manufacture are illustrated by drawings.

In FIG. 1 and 2 show the design of the hinge with the location of the fastening elements in one or different planes; in FIG. 3 and 4 are diagrams of formation and firmware of the elastic part of the hinge, respectively; in FIG. 5 is a diagram of the use of a hinge in a rotary nozzle.

The hanging hinge (Fig. 1, 2) contains an elastic part 1 with fastening elements 2 and 3. In it, the elastic part is made of woven 4 and 5 wound thread layers with their tight placement.

Braided and winding thread layers are formed around the fastening elements 2 and 3 located in the same or different parallel (Fig. 2) planes and in their area, which are part of them, and their location gives the hinge a flat or slightly conical shape.

The fastening elements themselves are made with the inclusion in their design of power rings 6 and 7 of a round or other section profile, for example, rhombic with an inflection around them of the same threads of the elastic part.

A method of manufacturing a hinge joint consists in sequentially performing assembly and winding operations: first, when it is carried out, the structural and technological frame of the hinge is preliminarily made of, for example, a woven sleeve with metal rings placed in width (the thread of the sleeve must be stretched), connect the ends of the rings, for example, by welding, and the sleeves, for example, gluing with firmware.

The rings are positioned and fixed with the extension of their planes in accordance with the hinge design and technological requirements, taking into account the subsequent change in the position of the winding threads during the formation of the fastening elements.

After this, the resulting frame is wrapped with the calculated number and angles of reinforcement of the filaments - layers 5 in FIG. 3, piercing the elastic part in the annular direction with piercing thread 8 and impregnating the entire joint with silicone.

In terms of use (Fig. 5), the hinge is mounted with the clamping rings 11 and 12 fixed on the movable 9 and fixed 10 parts of the structure, for example, as part of a rotary nozzle, and provides spatial rotation of the movable part according to the principle of spherical connection.

This invention is technically designed to be able to use a rotary nozzle under operating conditions.
