Abstract
A sealing ring (12) has an annular principal body (15) responsible for its dimensional stability, such body having an annular groove on at least one axial side, in which groove a sealing body (16), consisting of rubber-elastic material, is held. The sealing body (16) has a sealing bead (24) projecting axially past the principal body (15). The capacity of the annular groove (25) is at least equal to the volume of the sealing body (16) so that the annular groove (25) is in a position of receiving the material of the sealing body (16) defining its sealing bead (24) during action on and deformation of the sealing bead (24).
Claims17
A sealing ring comprising:
- an annular principal body responsible for dimensional stability and which on at least one axial side possesses a concentrically arranged annular groove having two radially opposite groove flanks, in which a sealing body, manufactured of rubber-elastic material, is held, which has a sealing bead projecting axially past the principal body, wherein within the annular groove an annular inner free space is provided radially within the sealing bead to receive the deformed material, and an annular outer free space is provided radially outside the sealing bead, the inner free space having a larger cross section at any point annularly than the outer free space, and wherein the capacity of the annular groove is at least equal to the volume of the sealing body so that the annular groove is in a position of also accepting the material, which defines the sealing bead, of the sealing body when the sealing bead is acted upon and deformed.
A sealing ring comprising:
- an annular principal body responsible for dimensional stability having two axial sides, and which on at least one of the two axial sides is a concentrically arranged annular groove having two radially opposite groove flanks, in which a first rubber-elastic sealing body is held, the first sealing body having a sealing bead projecting axially past the principal body, wherein within the annular groove an annular inner free space is provided radially within the sealing bead to receive the deformed material, and an annular outer free space is provided radially outside the sealing bead, the inner free space having a larger cross section than the outer free space, and wherein the capacity of the annular groove is at least equal to the volume of the first sealing body so that the annular groove is in a position of also accepting the material, which defines the sealing bead, of the first sealing body when the sealing bead is acted upon and deformed, and a second sealing body is provided on the other axial side of the principal body, the second sealing body is arranged in an annularly shaped groove, and wherein the first and second sealing bodies are connected together by material bridges integrally, such bridges extending through the principal body axially at peripherally distributed points.
