Abstract
This invention relates to a ball bearing cage which defines recesses for receiving balls in a single row. It is in the form of a ring obtained by casting or machining and intended to be interposed between an inner ring and an outer ring of a bearing. The recesses are distributed in two groups, the recesses of the first group each having an opening for positioning a ball located on a first side of the cage, while the recesses of the second group each have an opening for positioning a ball located on a second side of the cage, opposite the first side.
Claims11
Ball bearing cage in the form of a ring obtained by machining or casting, defining recesses for receiving balls in one row and intended to be interposed between an inner ring and an outer ring, of a bearing,
- wherein said recesses are distributed in two groups, each recess of the first group having an opening for positioning a ball located on a first side of said cage, while each recess of the second group has an opening for positioning a ball located on a second side of said cage, opposite the first side.
Process for assembling a ball bearing which comprises a single row of balls, disposed between an inner ring and an outer ring, and a cage defining recesses for receiving said balls, in which process balls are introduced in a volume defined between races formed respectively on said inner and outer rings,
- wherein it comprises the following steps of:
- introducing in said internal volume and via at least one notch made on one side of said bearing, a number of balls less than the nominal number of balls of said bearing,
- positioning said cage by causing said balls, already in place in said volume, to penetrate in recesses in said cage open on a first side of said cage, and
- introducing, via said notch or notches, a ball in at least one recess of said cage open on a second side of said cage.
