SEGMENTED CAGE FOR A BEARING
20170023064 · 2017-01-26 · ·

A segmented cage for a bearing is provided. The segmented cage provides at least two successive segments each being able to receive at least one rolling element. These segments have inner and outer circumferential faces and adjacent end faces abutting circumferentially one on the other. The adjacent end faces are shaped to obtain only one contact line or contact point between them, the contact point or contact line being distant from the inner and outer circumferential faces.

MULTI-MATERIAL CAGE
20170023061 · 2017-01-26 · ·

The invention provides a cage for a bearing. The invention further provides the bearing and a method of producing the cage. The cage includes a plurality of pockets at least partially surrounding the rolling elements. The cage further comprises a first material and a second material. The first material is a first printed material printed via an additive manufacturing process that has different properties compared to the second material. The first material is printed in the pockets at a position where, the rolling elements at least occasionally contact the pockets. Using such first printed material allows application of the first printed material at a location where it is needed.

Method for producing a rolling bearing cage for an axial-radial rolling bearing and axial-radial rolling bearing

The invention relates to a method for producing a rolling bearing cage for a rolling bearing comprising at least one row of rolling elements. In the method according to the invention, a ring or a ring element made of a metallic solid material is provided and shaped by a forming process and/or a cutting, material-removing process into an annular or segmented main body of the rolling bearing cage. The main body has openings for receiving a respective rolling element, the main body being heated to a temperature above a minimum coating temperature for thermal coating with a thermoplastic material powder, wherein the main body is then immersed in a fluidized bed containing the thermoplastic material powder, wherein thermoplastic material powder adheres to the main body, melts and forms a contiguous coating while the main body is present in the fluidized bed, and wherein, after the coating, the main body is removed from the fluidized bed. The invention further relates to an axial-radial rolling bearing with the described rolling bearing cage.

Cage segment for a segmented cage

A cage segment for a segmented bearing cage includes first and second end walls configured to oppose first and second end surfaces of a rolling element and a first side wall and a second side wall extending from the first end wall to the second end wall and defining with the first and second end walls end a pocket for receiving the rolling element. The first and second side walls are configured to oppose a curved side surface of the rolling element. The first and/or second end wall includes at least one protrusion extending into the pocket that is configured to contact an end surface of the rolling element. Also an assembly of the cage segment and the rolling element.
