Abstract

The invention relates to the protection of equipment and instruments from the effects of vibration and dynamic loads. The aim of the invention is to increase the carrying capacity of the shock absorber by compressing the elastic element along its entire length. The implementation of the shock absorber housing with protrusions passing through the holes in the piston and interacting with restrictive rings prevents the elastic element from moving, as a result of which the latter is compressed, and the toroidal cavity in which the toroidal elastic element is installed in the piston allows the shock absorber to absorb horizontal loads , and the piston rotates around the point of contact of the piston with the protrusion i of the body, as a result of which the elastic element is compressed along its entire length. 2 Il.

Description

HS

ac 1C its 112 invention of otHocHTCH to mechanical engineering, namely, to means of damping vibrations and shocks, and can be used in various engineering fields to protect equipment and instruments from the effects of vibrations and dynamic loads. The aim of the invention is to increase the carrying capacity of the shock absorber by compressing the elastic element along its entire length. FIG. 1 shows a shock absorber, general view, longitudinal section; in fig. 2 is a section A-A in FIG. 1. The shock absorber includes a housing 1, made with opposite-directed protrusions 2 located on its inner surface, a stem 3, sp., An elastic element 4 placed between them, filled with compressed gas, made in the form of a toroid, restrictive rings 5 interacting with an elastic element 4 and a piston 6 connected to the rod 3; Inside the piston 6 there is a toroidal cavity 7 and the holes 8 intersecting it with eccentricity, covering the projections 2. The diameter of the holes 8 is larger than the diameter of the projections 2. The absorber works as follows

at once.

Under the action of a vertical load, the piston 6 transfers the force to the elastic element 4 through the restrictive rings 5. The protrusions 2 of the housing 1 passing through the openings 8 and interacting with the restrictive rings 5 prevent the elastic element 4 from moving, as a result the latter is compressed, absorbing the energy of the external load . Under the action of horizontal force on the rod 3 upper edge of the hole 8 of the piston 6 with the

 in order to increase the carrying capacity of the shock absorber, the housing is made with opposing protrusions located on its inner surface, and the shock absorber is equipped with a piston connected to the rod, inside which there is a toroidal cavity and the eccentricity openings crossing it, and protrusions and diameter larger than , and the elastic element and restrictive rings are placed in the toroidal cavity between them. 7 our action force rests on the protrusion 2. At the same time, on the opposite side of the piston, a gap remains between the hole 8 and the protrusion 2. Since the action of a horizontal force relative to the point of contact of the piston 6 with the protrusion 2 results in a moment,. piston 6 rotates about this point. As a result, the elastic element 4 is compressed from the side of the action of the horizontal force by the lower limiting ring, and from the opposite side by the upper one. Thus, the elastic element 4 undergoes compression along its entire length and, in contrast to the prototype, it does not pump air into the unstressed part, due to which the damper carrying capacity increases. Claims of the invention A shock absorber comprising a body, a rod, an element in the form of a toroid between them, an elastic element, and restrictive rings interacting with an elastic element, characterized in that.
