Abstract
A bearing unit configured to support a first component for rotary movement with respect to a second component includes a first bearing having an inner ring and an outer ring and a second bearing having an inner ring and an outer ring and a separator axially disposed between and connecting the outer ring of the first bearing and the outer ring of the second bearing in an interference fit manner or in a friction fit manner to form a preassembled unit. The separator may be annular and have a plastic base body with axial openings in which metal spacers, cylindrical rods, for example, are mounted.
Claims16
A bearing unit configured to support a first component for rotary movement with respect to a second component, the bearing unit comprising:
- a first bearing having an inner ring and an outer ring;
- a second bearing having an inner ring and an outer ring;
- and
- a separator axially disposed between and connecting the outer ring of the first bearing and the outer ring of the second bearing in an interference fit manner or in a friction fit manner to form a preassembled unit.
A separator configured to axially space an outer ring of a first bearing from an outer ring of a second bearing in a bearing unit and to connect to the outer ring of the first bearing to the outer ring of the second bearing in an interference-fit manner, comprising:
- an annular base body made of plastic and having a first axial side configured to contact the outer ring of the first bearing and a second axial side configured to contact the outer ring of the second bearing and a central hole and at least two openings radially spaced from the central hole and extending from the first axial side to the second axial side and a metal spacer in each of the at least two openings, each of the at least two spacers having an axial length equal to or greater than a distance between the first axial side and the second axial side.
A bearing unit configured to support a first component for rotary movement with respect to a second component, the bearing unit comprising:
- a first bearing having an inner ring and an outer ring, the outer ring of the first bearing having a first axial side and having a radially outwardly facing annular groove;
- a second bearing having an inner ring and an outer ring, the outer ring of the second bearing having a first axial side configured to face the first axial side of the first bearing in the bearing unit and the outer ring of the second bearing having a radially outwardly facing annular groove;
- and
- a plastic annular separator having a first projection extending into the annular groove of the outer ring of the first bearing and a second projection extending into the annular groove of the outer ring of the second bearing and connecting the first bearing to the second bearing in an interference fit manner, the separator having a first annular surface facing the first axial side of the outer ring of the first bearing and a second annular surface facing the first axial side of the outer ring of the second bearing and a central hole and at least two openings radially spaced from the central hole and extending from the first annular surface to the second annular surface and a metal spacer in each of the at least two openings, each of the at least two spacers being in contact with the outer ring of the first bearing and the outer ring of the second bearing.
