Patent ID: 7918607

Claim:
A roller bearing comprising: an inner ring having a raceway extending diagonal relative to a longitudinal axis of the roller bearing; an outer ring having a raceway extending diagonal relative to the longitudinal axis of the roller bearing; a plurality of conical rolling bodies, each conical rolling body being provided with its own rotation axis and positioned between the raceways of the inner and outer rings to allow relative rotation of the inner and outer rings; and a shell comprising: a tapered annular body having a large diameter end and a small diameter end, wherein the tapered annular body is mounted between the inner and outer rings, the tapered annular body comprising equally distributed openings, wherein a conical rolling body is positioned along its own rotation axis (R) in each of the openings, an annular oil thrower extending radially relative to each transversal edge of the inner and outer rings wherein each annular oil thrower includes at least one radial inner protrusion extending from the large and small diameter ends of the tapered annular body toward the inner ring and at least one radial outer protrusion extending from the large and small diameter ends of the tapered annular body toward the outer ring, wherein the radial inner protrusion of each annular oil thrower extends to the transversal edge of the inner ring, wherein a free end of each protrusion is positioned opposite and away from a corresponding one of the inner and outer ring, wherein axial and radial functional clearances are defined between the radial inner and outer protrusions and the inner and outer rings, and wherein the axial and radial functional clearances are dimensioned to allow passage of a bearing lubrication fluid therethrough and serve as a barrier to passage of solid particles therethrough.
