Изобретение относитс к устройствам гашени комбинированных динамических воздействий и может быть использовано дл заш.иты различного оборудовани от воздействи синусоидальной вибрации, от ударов с амплитудой, превышающей во много раз амплитуду вибрационных нагрузок, при одновременном воздействии линейных ускорений .The invention relates to damping devices of combined dynamic effects and can be used for securing various types of equipment from the effects of sinusoidal vibration, from shocks with an amplitude exceeding many times the amplitude of vibration loads, while simultaneously acting by linear accelerations.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс амортизатор, содержащий концентрично расположенные втулки и упругий элемент в виде троса, св зывающий между собой втулки 1.The closest to the invention in technical essence and the achieved result is a shock absorber containing concentric spaced sleeves and an elastic element in the form of a cable connecting the sleeves 1 to each other.

Однако известный амортизатор не обладает одинаковым защитным свойством во всех направлени х, не обеспечивает защитные свойства от комбинированных динамических воздействий, необходимые характеристики при т желых услови х эксплуатации .However, the known shock absorber does not have the same protective properties in all directions, it does not provide protective properties against combined dynamic effects, the necessary characteristics under severe operating conditions.

Цель изобретени -обеспечение изол ции комбинированных динамических воздействий и уменьщение габаритов амортизатора.The purpose of the invention is to provide isolation of the combined dynamic effects and reduce the size of the shock absorber.

Указанна цель достигаетс тем, что в амортизаторе внутренн втулка выполненаThis goal is achieved by the fact that in the damper the inner sleeve is made

в виде двух фланцев, св занных между собой расположенными параллельно оси стержн ми , на торцах наружной втулки выполнены пазы, количество которых равно количеству стержней, а упругий элемент намотан последовательно по участкам, каждыйin the form of two flanges connected with each other by rods arranged parallel to the axis, grooves are made at the ends of the outer sleeve, the number of which is equal to the number of rods, and the elastic element is wound sequentially in sections, each

5 из которых расположен в пазу наружной втулки на одном торце, между двум стержн ми , скрещива сь с ними и под углом к оси амортизатора, во втором пазу наружной втулки на другом торце и по образующей наружной втулки.5 of which is located in the groove of the outer sleeve on one end, between two rods, crossing them and at an angle to the axis of the shock absorber, in the second groove of the outer sleeve on the other end, and forming the outer sleeve.

На фиг. 1 показан предлагаемый амортизатор , общий вид; на фиг. 2 - пример намотки троса (где число пар пазов и число стержней равно п ти).FIG. 1 shows the proposed shock absorber, general view; in fig. 2 is an example of cable winding (where the number of pairs of slots and the number of rods is five).

Амортизатор содержит концентричноThe shock absorber contains concentric

15 расположенные втулки 1 и 2 и упругий элемент 3, св зывающий между собой втулки. Втулка 2 выполнена в виде двух фланцев 4 и 5, св занных между собой расположенными параллельно оси стержн ми 6, а на торцах втулки 1 выложены пазы 7.15 spaced sleeves 1 and 2 and an elastic element 3 interconnecting the sleeves. The sleeve 2 is made in the form of two flanges 4 and 5, interconnected by rods 6 arranged parallel to the axis, and grooves 7 are lined at the ends of sleeve 1.

Claims

20 In case of dynamic effects, the turns of the elastic element 3 work for stretching, which leads to the mutual movement of the structural elements of the elastic element and the mutual movement of the turns of the elastic element 3 relative to the structural elements of the shock absorber. This makes it possible to obtain a significant amount of damping and a combined rigid power characteristic to provide the necessary protective parameters against combined dynamic effects. The proposed design dramatically reduces the size of the shock absorber and creates a unified series of shock absorber sizes depending on the load capacity and levels of the combined dynamic effects, regardless of the geometric shape of the depreciable object and the direction of the variable forces. Claims of the invention A shock absorber comprising concentric spaced bushes and an elastic element in the form of a cable interconnecting bushes, characterized in that, in order to isolate the combined dynamic effects and size reduction, the internal bushings are made in the form of two flanges interconnected parallel to the axis of the rods, at the ends of the outer sleeve are grooves, the number of which is equal to the number of rods, and the elastic element is wound sequentially in sections, each of which is located in n zu outer sleeve at one end between the two rods, crossing Referring to them and at an angle to the axis of suspension in the second recess of the outer sleeve at the other end and along a generatrix of the outer sleeve.
