technical field

The invention relates to a shock absorber configured for a textile machine, in particular to a shock absorber.

Background technique

Textile machinery will generate large vibrations during the working process, which is not only accompanied by large noise, but also seriously affects the service life of the equipment. Due to the excellent shock absorption properties of rubber, rubber shock absorbers are widely used in various types of machinery, automobiles, railway locomotives, water vehicles, airplanes and other aircraft.

Sometimes a single rubber shock absorber cannot achieve the desired effect, such as a rubber shock absorber of aluminum-magnesium alloy shown in CN201554812U, although the rubber shock absorber has the functions of limiting large displacement and step slack limit, but the The structure of the rubber shock absorber is relatively complicated, and the heat dissipation capacity is insufficient, and the metal material used has no further effect.

The shock-absorbing assembly includes an upper rubber sheet, an upper shock-absorbing sheet, a pair of lower rubber sheets and a pair of lower shock-absorbing sheets arranged sequentially from top to bottom.

Both sides of the upper shock-absorbing sheet are formed with downwardly bent upper wings.

A lower shock-absorbing sheet is positioned below each upper wing; the inner side of the lower shock-absorbing sheet is formed with an upwardly bent lower wing, and the inner side of the lower wing is also formed with a horizontally extending inner edge.

A lower rubber sheet is fixed between the upper shock-absorbing sheet and the lower shock-absorbing sheet; the outer side of the lower rubber sheet is formed with a downwardly curved rubber wing.
