Claims
- 1. A rubber block, comprising a block shaped to include at least a segment of a circular washer having at least one generally radially extending load bearing surface disposed at at least one end of said segment, said load bearing surface adapted to receive a circumferential load acting thereagainst, a plurality of hollow ducts regularly distributed in the block and all of which ducts in the block have longitudinal axes which are respectively mutually parallel to each other and essentially perpendicular to a main plane of the block, which main plane is essentially perpendicular to said at least one load bearing surface, wherein said hollow ducts intersect cavities regularly distributed through the block, said cavities having a cross-sectional area in a direction perpendicular to the longitudinal axis of the associated duct which is larger than a corresponding cross-sectional area of the hollow ducts intersecting said cavities.
- 2. Rubber block defined in claim 1, wherein the hollow ducts are circumferentially spaced from each other and arrayed along imaginary concentric circles.
- 3. Rubber block defined in claim 3, wherein the hollow ducts arrayed in one of the imaginary concentric circles are staggered relative to the ducts arrayed in an imaginary adjacent concentric circle.
- 4. Rubber block defined in claim 1, wherein the cross-sections of the hollow ducts and of the cavities remain constant in the radially outer direction of the segment.
- 5. Rubber block defined in claim 1, wherein the cavities are shaped as spheres arrayed inside the block in a spatially regular manner and staggered relative to one another as a space-centered grid flaring in a radially outward direction of the block.
- 6. Rubber block defined in claim 1, wherein each hollow duct crosses at least three cavities.
- 7. Rubber block defined in claim 1, wherein said at least one load bearing surface also defines at least one radially extending mounting surface extending toward a main axis of the block.
- 8. Rubber block defined in claim 7, further including a rigid, load-absorbing plate located adjacent said mounting surface.
- 9. Rubber block defined in claim 1, wherein external surfaces of the block are fluorinated.
- 10. The rubber block of claim 1, wherein said at least one end of said segment extends in a radial plane.
- 11. A rubber block comprising a block shaped to include at least a segment of a circular washer having at least one load bearing surface disposed at at least one ed of said segment, a plurality of hollow ducts regularly distributed in the block and which ducts are essentially perpendicular to a main plane of the block, which main plane is essentially perpendicular to said at least one load bearing surface, wherein said hollow ducts intersect cavities regularly distributed through the block, said cavities having a cross-sectional area in a direction perpendicular to the longitudinal axis of the associated duct which is larger than a corresponding cross-sectional area of the hollow ducts intersecting said cavities, wherein the hollow ducts are circumferentially spaced from each other and arrayed along imaginary concentric circles, and wherein the cross-sectional areas of the hollow ducts and of the cavities in the rubber block increase in size in the radially outward direction of the block.
