Abstract
A hub-bearing assembly for rotatably mounting a tilling disc about an axis of rotation. The hub-bearing assembly includes an annular hub providing an axially extending tubular portion, comprising a housing and a radially outer flange for mounting a disc. A bearing unit is mounted within the housing. An elastic damping body axially is fitted between the radially outer flange and the disc.
Claims6
A hub-bearing assembly for rotatably mounting a tilling disc about an axis of rotation, the assembly comprising:
- an annular hub providing an axially extending tubular portion, comprising a housing and a radially outer flange for mounting a disc;
- a bearing unit mounted within the housing, the bearing unit comprising:
- an outer ring,
- a pair of inner rings, and
- a dual set of rolling elements, interposed between the outer ring and the pair of inner rings;
- and
- an elastic damping body axially fitted on the radially outer flange, on the side facing the mountable tilling disc, the elastic damping body further comprising a substantially annular wall, the substantially annular wall is steadily connected to a substantially cylindrical wall, the cylindrical wall being in a radially external position respect to the annular wall, the elastic damping body is fabricated of one of an elastomeric material or a plastic material, wherein the cylindrical wall of the elastic damping body is radially coupled with the flange, by:
- a substantially cylindrical surface of the cylindrical wall, in a radially internal position, and
- a corresponding substantially cylindrical surface of the flange, in a radially external position.
