Abstract
The invention relates to a bearing cage of a bearing means, in particular a ball or roller bearing, which is produced by means of a generative manufacturing method and has an outer flange and a bearing seat, which are joined together via a plurality of spring beams.
Claims20
A bearing cage (1) of a bearing, which is produced by means of a generative manufacturing method, comprising:
- an outer flange (2) and a bearing seat (8), which are joined together via a plurality of spring beams (3, 5, 7).
(canceled)
A method for designing, repairing, and/or replacing a bearing cage of a bearing having an outer flange (2) and a bearing seat (8), which are joined together via a plurality of spring beams (3, 5, 7), comprising the steps of:
- applying a powder layer, which can be solidified by means of radiated energy, onto a support;
- solidifying the powder layer by means of radiated energy from a source of radiated energy in a component region of the powder layer, wherein the component region is the bearing cage region;
- moving the support by one layer thickness and application of the next powder layer;
- solidifying the powder layer by radiated energy from a source of radiated energy in the component region of the powder layer;
- and
- repeating the preceding steps until a finished bearing cage has been constructed from the solidified component regions.
