Abstract
Half-cage for forming cages (10) for ball bearings, in which the half-cages (11, 21) comprise semi-spherical recesses (12, 22) arranged at predefined intervals along a circumference. The semi-spherical recesses are spaced out from each other by means of respective planar portions (14, 24), are arranged along the circumference, and comprise at least one rib (31, 41) having a certain width and extending along the circumference over at least the whole surface of said recesses.
Claims13
A half-cage for ball bearings, comprising
- semi-spherical recesses arranged at predefined intervals along a circumference, said semi-spherical recesses being spaced out from each other by way of respective planar portions;
- wherein said recesses, arranged along the circumference, comprise
- at least one central rib having a certain width, which rib extends along the circumference over at least the whole surface of said recesses and along each of said planar portions and merges into the surface of each of said planar portions next to clear areas provided in said planar portions.
A cage for ball bearings, comprising
- a first half-cage and a second half-cage, each of said first half-cage and said second half-cage comprises semi-spherical recesses arranged at predefined intervals along a circumference, said semi-spherical recesses being spaced out from each other by way of respective planar portions, and each of said recesses include at least one central rib having a certain width, which rib extends along the circumference over at least the whole surface of said recesses and along each of said planar portions and merges into the surface of each of said planar portions next to clear areas provided in said planar portions,
- wherein the first and the second half-cages are coupled together such that the semi-spherical recesses of said first half-cage face the semi-spherical recesses of said second half-cage and the planar portions of said first half-cage face the planar portions of said second half-cage.
