Abstract:
A method for producing a cage having a body with multiple pockets for rolling elements, the method providing: a) defining a cage basis geometry that provides a radial outer and/or inner surface for contacting a bearing ring and multiple surfaces of the pockets for contacting the rolling elements; b) defining a part of the radial outer and/or inner surfaces as being unalterable surfaces; c) calculating the cage stress distribution when applying a defined stress force from a mathematical model; d) defining cage volume sections where the stress is below a defined threshold; e) removing a part of the volume sections defined according to step d) taking into account the unalterable surfaces according to step b) and the surfaces of the pockets that are unalterable surfaces; f) defining the cage geometry with the removed volume sections; g) manufacturing the cage according to the geometry as defined according to step f).
