Abstract
A bearing bushing (1) and to a method for manufacturing a bearing bushing are provided. The bearing bushing includes a wire article (2) formed from knitted wire mesh or knitted wire fabric (6) and compressed into a dimensionally stable compressed product (3). The bearing bushing can be provided for supporting a throttle valve used in high-temperature applications. The wire article (2) is formed from a stainless steel. Existing voids (10) of the compressed product (3) are filled with solder (4).
Claims9
A bearing, bushing (1) comprising a wire article (2) formed from a knitted wire mesh or knitted wire fabric (6) compressed into a dimensionally stable compressed product (3), the bearing bushing being provided for supporting a throttle valve used in high-temperature applications, wherein:
- the wire article (2) is formed from a stainless steel,
- existing voids (10) of the compressed product (3) are filled with solder (4), and
- the wire article (2) comprises a tube section (5) cut to length from a tube formed from the knitted wire mesh or knitted wire fabric (6), the knitted wire mesh or knitted wire fabric (6) has a plurality of stitch courses (8) arranged in a longitudinal direction (7) of the tube.
A method for manufacturing a bearing, bushing (1) comprising:
- performing a first series of steps that includes:
- providing a wire article (2) made of a tube section (5) of a stainless steel knitted wire mesh or wire fabric tube;
- and
- compressing the wire article (2) into a dimensionally stable compressed product (3) having an outer shape of the bearing bushing (1);
- performing a second series of steps that include:
- feeding the compressed product (3) into a continuous furnace;
- and
- soaking the compressed product (3) with solder (4) in an annealing process.
