Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
Water lubricated bearing means, comprising a tubular elastic composite bearing member formed of an elastomeric material of moderate elasticity; a plurality of segmental lining members arranged in circumferentially spaced relation on the inside surface of said bearing member, each of said lining members being formed of a thermoplastic synthetic resin compound selected from the group comprising tetrafluoroethylene, polyethylene or polyacetal and at least one filler, the spaces between said lining members defining lubricating grooves; tubular bushing means containing a cylindrical chamber in which said bearing means is concentrically mounted; and bearing support means containing a cylindrical bore in which said bushing means is concentrically mounted.
Claim 2
Dependent Claim
105 words
Water lubricated bearing means, comprising a tubular elastic composite bearing member formed of an elastomeric material of moderate elasticity; a plurality of segmental lining members arranged in circumferentially spaced relation on the inside surface of said bearing member, each of said lining members being formed of a thermoplastic synthetic resin compound selected from the group comprising tetrafluoroethylene, polyethylene or polyacetal and at least one filler, the spaces between said lining members defining lubricating grooves; tubular bushing means containing a cylindrical chamber in which said bearing means is concentrically mounted; and bearing support means containing a cylindrical bore in which said bushing means is concentrically mounted.
Claim 3
Dependent Claim
116 words
Water lubricated bearing means as defined in claim 1, wherein said composite bearing means comprises a sectional bearing member including a plurality of composite bearing segments obtained by sectioning the composite bearing member longitudinally along the water lubricating grooves, said composite bearing segments being attached to the inner surface of said bushing means with the adjacent composite bearing segments being adjacent and spaced from each other; at least one retaining member 3 4 interposed between the adjacent composite bearing segments and in contact with the inner surface of said bushing means; and means connecting said retaining member with said bushing, whereby said composite bearing segments are securely anchored to the inner surface of said bushing means.
Claim 4
Dependent Claim
25 words
A water lubricated bearing device as defined in claim 2, wherein a core member is embedded in each of said elastic composite bearing member segments.
Claim 5
Dependent Claim
45 words
A water lubricated bearing device as defined in claim 3 wherein the surface of each of said elastic composite bearing member segments in contact with the inner surface of said bush is provided with a recess of a suitable configuration to vary the elasticity thereof.
Claim 6
Dependent Claim
45 words
A water lubricated bearing device as defined in claim 2 wherein the surface of each of said elastic composite bearing member segments in contact with the inner surface of said bush is provided with a recess of a suitable configuration to vary the elasticity thereof.
Claim 7
Dependent Claim
132 words
Water lubricated bearing means, comprising a tubular elastic composite bearing member formed of an elastomeric material of moderate elasticity; a plurality of segmental lining members arranged in circumferentially spaced relation on the inside surface of said bearing member, each of said lining members being formed of a thermoplastic synthetic resin compound including at least one filler, the spaces between said lining members defining lubricating grooves; tubular bushing means containing a cylindrical chamber in which said bearing means is concentrically mounted; and bearing support means containing a cylindrical bore in which said bushing means is concentrically mounted, said lining members being formed of a resin compound selected from the group comprising tetraflouroethylene, polyethylene or polyacetal and at least one filler selected from the group consisting of carbon, graphite, glass, bronze or molybdenum bisulfide.
Claim 8
Dependent Claim
