Description

f1

The invention relates to mechanical engineering and can be used to dampen oscillations in reciprocating systems.

The purpose of the invention is to increase the course of the axial movement of the damper, thereby increasing the damping effect.

Figure 1 shows the damper, a general view; figure 2 - section aa in figure 1; FIG. 3 shows a damper, an embodiment; on figa - section bb on

figure 3.

The damper consists of telescopically mounted elements 1 and 2; grooves 3 are made on the surfaces of elements 1 and 2 facing each other.

and 4 and the rolling body 5 located at the intersection of the grooves 3 and 4.

The damper works as follows

5 When moving element 2 up or down, the rolling body 5 (ball) moves simultaneously along the grooves 4 and along the screw grooves 3. At the same time, the ball 5 cannot participate in two differently directed movements without the friction in one direction. When moving element 2 at low speed, the friction of the ball 5 from the grooves 3 and 4 is small. With an increase in speed of 15 (movement of element 2, friction increases faster than the increase in the speed of the element.
