SU1490343A1 - Shock-absorber - Google Patents

Abstract

The invention relates to instrumentation, primarily to electronic equipment for its protection from vibrations and shocks. The aim of the invention is to expand the range of perceived loads and improve vibration isolation by providing independent preloading of the springs in the initial state in accordance with the actual static load. Under the action of the axial load, the load rod 4, together with the segments 2, tension 7, washer 10 and nut 11, move downward by the magnitude of the working stroke to a state of static equilibrium, causing additional deformation of the springs 5 and 6. 1 sludge.

A contact nut 9 with a cylindrical cup 8 with 25 vibrations, and an external spring 6 is placed between the sleeve nut 9 and the segments 2.

The shock absorber works as follows.

Depending on the load action of the required stroke and the required pressure in the contact between the load rod 4 and the segments 2, which ensure effective damping of the horizontal oscillations, the amount of preload 5 and 6 is established.

First, an assembly is assembled that includes the loading rod 4, the clamp 7, the spring 5, the cylindrical cup 8, the washer 10 and the nut 11. The rotation of the nut 11 provides the necessary pressing of the internal spring 5. At the same time, the spring force is clamped: 7 and is not transmitted to the load bar 4.

Then, the assembled knot: g together with the segments 2 and the spacer spring 3, which provide vertical vibration damping, is placed in the cover of the housing 1. After that, the outer spring 6 is inserted up to the stop in the segment 2 and the necessary initial preload is carried out by rotating the sleeve nut 9.

The shock absorber provides effective damping of horizontal oscillations in a much wider range of loads by adjusting P1I friction force depending on the actual static load, and the efficiency of vibration isolation in the entire resonant zone improves.
