(54) АМОРТИЗАТОР(54) SHOCK ABSORBER

1one

Изобретение относитс к машиностроению и может быть использовано дл защиты от вибраций и ударов различных объектов..The invention relates to mechanical engineering and can be used to protect against vibrations and impacts of various objects.

Известен амортизатор, содержащий две опоры, одна из которых предназначена дл св зи с подвижным объектом, а друга - с основанием, расположенную между ними промежуточную массу и упругие элементы, св зывающие промежуточную массу с опорами 1 .A shock absorber is known that contains two supports, one of which is intended to communicate with a moving object, and the other with a base, an intermediate mass between them and elastic elements connecting the intermediate mass with the supports 1.

Недостатком известного амортизатора вл етс невозможность регулировки его частотных характеристик.A disadvantage of the known shock absorber is the impossibility of adjusting its frequency characteristics.

Наиболее близким к изобретению по технической сущности и достигаемому а(|фекту вл етс амортизатор, соде1 жащий две опоры, одна из которых предназначена дл св зи с подвижным объектом , а друга - с основанием, расположенную между ними полую промежуточную массу, в полости которой размещен регулировочнь1й элемент, выполненный в виде турбинного частично заполненкого жидкостью колеса, и упругие элементы , св зывающие промежуточную массу с опорами 2 .The closest to the invention in technical essence and achievable a (| effect is a shock absorber containing two supports, one of which is intended for communication with a moving object, and the other with a base located between them a hollow intermediate mass in which cavity an adjusting element, made in the form of a turbine wheel partially filled with liquid, and elastic elements connecting the intermediate mass with the supports 2.

Однако данный амортизатор сложен по конструкции, поскольку он требует надежности герметизашга полости промежуточной массы, в которой размещено токсичное вещество.However, this shock absorber is complicated in design, since it requires the reliability of sealing the cavity of the intermediate mass in which the toxic substance is housed.

Цель изобретени - упрощение конструкции амортизатора.The purpose of the invention is to simplify the construction of the shock absorber.

Указанна цель достигаетс тем, что регулировочный элемент выполнен в виде плоской спиральной пружины, внещним концом соединенной с массой, а внутренним - с оськ), установленной в This goal is achieved by the fact that the adjusting element is made in the form of a flat spiral spring, the outer end connected to the mass, and the inner end to the axle, installed in

15 опоре с возможностью осевого перемещени .15 support with the possibility of axial movement.

Claims

20 and 2, one of which .1 is intended for communication with a moving object, and the other is the 2nd base, a hollow intermediate mass 3 and elastic elements 4 between them, CBsiabma intermediate mass 3 with supports and 2. In the cavity of intermediate mass 3 An adjustment element is inserted, made in the form of a flat spiral spring 5, the outer end connected to the mass 3, and the inner end to the axis installed through the threaded bushing in the support 2: with the possibility of axial displacement. The shock absorber works in the following way. . Selection of the twisting moment of the flat spiral spring 5 ensures the optical rigidity of the shock absorber in a dynamic mode, which allows effectively damping oscillations of the protected object. The use of a flat spiral spring as an adjusting element greatly simplifies the design of the shock absorber and improves its technical and economic performance. Formula of the Invention A shock absorber containing two supports, one of which is intended for communication with a suspended object, and the other with a base, a hollow intermediate mass located between them, in the cavity of which an adjustment element is placed, and elastic elements connecting the intermediate mass with supports This is due to the fact that, in order to simplify the design, the adjusting element is made in the form of a flat spiral spring, the outer end connected to the mass, and the inner one - to the axis installed in the support with the possibility of axial displacement scheni. sources of information taken into account during the examination 1.
