Abstract

The damper comprises a base block (1) resting on the ground or foundation (6) and a load supporting block (4) disposed thereabove and supporting an object (7), such as a machine. The adjacent faces of the two blocks are provided with mirror- symmetric recesses diverging towards each other and delimiting a cavity between the two blocks (1,4). In the cavity is received two discrete parts (2,3) interconnected by a prestressed spring element (5) which forces them apart. The elements have walls diverging at the same angle ??? as the recesses. The walls of the elements (2, 3) are forced by the force of the spring element (5) into contact with the walls of the recesses, so that frictional contact takes place between said walls when the supporting block (4) is displaced relative to the base block (1) to compensate for load or pressure of object (7). The absorber may be inserted into volute or cylindrical spring-loading elements. <IMAGE>

Odpruženie doteraz používanými odpružovacími elementární, ako sú válcové, listové, tanierové a iné pružiny je ekonomicky a konátrukčne poměrně dosí náročné. Pri odpružovaní atrojov s impulsovými účinkami, pomocou tradičných pružiacich prvkov, dochádza к nadekakovaniu atrojov. V takýchto pripadoch je potřebné zvýálí statické predpatie pružin hmotnoaiou základového bloku pod vlaetným o trojným zarladěním, čím sa odpružovanie stává náročnejčie na podoryané a híbkové rozmary zakladania odpružovaného atroja. Tým aa samotné zakladanie zdražuje a stává sa náročnějším na rozsah práč. Značné problémy vznikájú pri pasivnou odpružovaní zariadení citlivých na otřas, ktoré sa nachádzajú v blízkosti zariadení s dynamickými účinkami. Takými aú například citlivé elektronické riadiace a kontrolné aperatdry a uzly atrojov a výrobných llnlek, alebo citlivé technologické zariadenia, labaratomé skúéobné a přístrojové zariadenia, eamočinné počítače a ich jr ísluženstvo a pod.Suspension of hitherto used suspension elements, such as cylindrical, leaf, disc and other springs, is economically and structurally quite demanding. The suspension of the machines with impulse effects, with the help of traditional spring elements, causes the machines to overload. In such cases, it is necessary to increase the static pre-tension of the springs by the mass of the foundation block under the triple-level flywheel, thereby making the suspension more demanding for the undercut and depth of the foundation of the suspension and machine. This makes the creation itself more expensive and becomes more demanding in terms of washing. Significant problems arise in the passive cushioning of shock-sensitive devices which are located near devices with dynamic effects. Such as, for example, sensitive electronic control and monitoring aperatters and nodes of machines and production lines, or sensitive technological equipment, labaratomic testing and instrumentation equipment, oumachine computers and their services and the like.

Nedostatky a problémy vznikájúoe pri odpružovaní klasickými pružiaoimi elementární odstraňuje frikčný izolátor a nemeniaoim se pcierezom a volitelným stupňom pruženia s možnosíou i dodatečného ladenia intenzity tlmenia podía vynálezu, kterého podstata spočívá v tom, že pozoetáva z podstavnej časti a vybráním, uložonej na pevnom podklade. Vybranie sa kónicky zužuje pod uhlom menéím ako 180°. fialeJ pozoetáva z úložnéJ časti s vybráním, kónicky se zužujícím pod tým ietým uhlom meněím ako 180°. Úložnáčaaí je zrkadlovo uložená к podetevovej časti. Medzi týmito časíami je prvá vnútorná část so styčnými plochami kónicky tvarovanými pod uhlom ^/2, ktorá je spojená pružiacim elementem a druhou vnútornou časíou so styčnými plochami kónicky tvarovanými pod uhlom <f/2.The drawbacks and problems encountered in the cushioning of conventional springs are eliminated elementally by the friction insulator and do not vary with the cross section and the optional degree of springing with the possibility of additional tuning of the damping intensity according to the invention. The recess tapers conically at an angle of less than 180 °. violet is pivoted from the receiving portion with a recess tapering conically at the same angle of less than 180 °. The storage device is mirrored to the underlay part. Between these parts there is a first inner part with conical faces conically shaped at an angle? / 2, which is connected by a spring element and a second inner part with the conical faces conical shaped at an angle? / 2.

Pri použití prvku na odpruženie kmltajúcich zariadení ea podatatne znížia náklady na prevedenie odpruženie z důvodov zmenženia půdorysných a híbkových rozměrov založenia, pričom odpadajú nároky na prevedenie osobitného základového bloku medzi atrojom a elementární odpruženie bez nárokov na inétalovanie přídavných tlmičov. Jeho malé rozměry a konStantný půdorys pri Jeho funkčnom působení umožňuje jeho vloženio do bežnej veleověj pružiny, z čoho vyplývá možnosí Jeho dodatočného namontovania v pripadoch nevyhovujúceho odpruženie bez nárokov na atavebnokonžtrukčné úpravy pri rekončtrukeiáeh.When using the cushioning element of the oscillating devices ea, the cost of converting substantially reduces the cushioning due to the reduction of the ground and depth dimensions of the foundation, eliminating the need to convert a separate foundation block between the machine and elemental cushioning without requiring additional dampers. Its small size and constant footprint during its functional action allow it to be inserted into a conventional vele spring, which implies the possibility of its retrofitting in cases of unsatisfactory suspension without the need for construction and structural modifications during reconstruction.
