Author of the invention SIMKO MILAN ing., DOLNÝ KUBÍN (54) Sliding bearing for swinging or linear movement

The subject of the invention is a sliding bearing of an overflow or rectilinear motion, usable for storing bridge and building structures and for other similar arrangements.

In addition, for the laying, in particular bridges, sliding bearings, either with planar or spherical function surfaces, are used. Teflon lining and similar are sandwiched between the function surfaces of the bearings in order to achieve a higher wear resistance lifetime by applying high pressures. The pressure is transmitted by means of prototypes made mostly of austenitic polished steels. In sliding bearings for bridges and buildings, constructional guides from sheet metal inserts between flat or spherical contact surfaces are known. The use of such protrusions not only adjacent to the high cost, but often does not achieve such good sliding properties as conventional steel with polyamide. In addition, austenitic polished screens cannot be used for spherical surfaces. Also known are pendulum bearings 5 by using rubber, which ages rapidly, impairs properties and reduces bearing life. 216283

The necessary bearing replacement requires time-consuming and disabling operations.

The sliding bearing of the invention removes the aforementioned defects considerably. The bearing consists of the upper sliding roof, above. by which the anchoring plate is positioned, from the base plate and from the spherical cap between the top and base plates.

It is an object of the present invention that a layered plastic or a milky polished chromium is deposited on the bottom of the spherical cap and adheres to a teflon-lined liner attached to the spherical flat bottom. On the upper flat flat spherical cap, there is a layer of Teflon adhered to the bottom, which is the surface area of the high-viscosity, in contact with the lower, plastic and bleached ohm.

The sliding bearing according to the invention improves the insertion of particularly bridge and building structures. Furthermore, it is useful in pre-pipe mountings as well as in the assembly of heavy parts, assemblies and other similar mountings, for example, the storage of nuclear reactors. The expensive austenitic sheet is replaced with coatings

Claims (1)

SUBJECT Plain bearing for pendulum or linear movement, in particular for bridge, building and piping structures, with an upper sliding plate, with a base plate and with a spherical cap, characterized in that a molten layer (6) of melt is applied to the lower spherical section of the spherical cap In the spherical recess of the base of that base 2, a teflon lining 5 is attached, to which a layer 6 of molten plastic, for example of polyamide, or of polished chrome is adhered. This layer 6 is applied to the spherical surface of the spherical cap 3. An anchor plate 7 is attached to the upper slide plate 1. A sealing ring is provided between the base plate 2 and the upper slide plate 1 to prevent dirt from entering the bearing. 8th polished chrome adjacent to a teflon lining (5) mounted on a spherical flat thatched base (2) and a teflon lining (4) on the upper planar flat spherical cap (3) contacting the plasticized or milky chrome surface upper sliding thatch (1).
