Abstract:
1. A hub-bearing assembly for rotatably mounting a tilling disc about an axis of rotation, the hub-bearing assembly comprising: an annular hub including: a bearing unit mounted within the housing and comprising an outer ring, a pair of inner rings and a dual set of rolling elements, interposed between the outer ring and the inner rings; and an elastic damping body arranged in the housing and radially interposed between the hub and the outer ring of the bearing unit, wherein the elastic damping body extends axially outwardly past a first axial end and a second axial end of the outer ring, wherein one axial end of the elastic damping body is free of abutment, the housing is delimited radially by a substantially cylindrical inner wall, and wherein the outer ring provides a radially outer surface, the elastic damping body further comprising a tubular sleeve of elastomeric material, radially interposed between the substantially cylindrical wall of the housing and the radially outer surface of the outer ring, the elastic damping body is provided with a tubular wall having a radial thickness which, in an undeformed condition, is greater than a radial distance separating the radially outer surface of the outer ring from the substantially cylindrical wall of the housing, whereby the elastic damping body is radially compressed between the housing and the outer ring, wherein the radially outer flange extends from a first axial end of the tubular portion of the hub; a radially inner flange extends from a second axial end of the tubular portion; and an annular groove formed in the housing, wherein the annular groove extends into the radially inner flange and receives an edge of the elastic damping body, wherein the radially inner flange extends over a radial side of a sealing device.
