Abstract
The invention concerns a bearing component (Ia, Ib, 1, 7, 9) for a rolling (13, 14, 16) or sliding bearing (19), wherein the bearing component (Ia, Ib, 1, 7, 9) is one of an inner ring (Ia, 1), an outer ring (Ib, 7), a rolling element (9), a cage, or a guide ring. The bearing component (Ia, Ib, 1, 7, 9) comprises a first material (2), and a second material (3) joined to the first material (2), wherein the second material (3) and the first material (2) having been joined by a semi-solid metal process.
Claims14
A bearing component for a rolling bearing, the bearing component comprising:
- a body formed of a first material and a second material joined to the first material by a semi-solid metal process and configured as one of:
- an inner ring,
- an outer ring, and
- a rolling element,
- the body having a molecular grain structure formed between the first material and the second material, wherein the molecular grain structure is a result of and associated uniquely with the semi-solid metal process.
A rolling bearing comprising:
- an inner ring, an outer ring, and a plurality of rolling elements, wherein at least one of the inner ring, the outer ring, and the plurality of rolling elements is formed of a first material and a second material joined to the first material by a semi-solid metal process,
- wherein the first material is a first metal and the second material is a second metal which is different from the first metal,
- the at least one of the inner ring, the outer ring, and the plurality of rolling elements having a molecular grain structure formed between the first material and the second material, wherein the molecular grain structure is a result of and associated uniquely with the semi-solid metal process.
A sliding bearing comprising a bearing component formed of a first single material having a first material surface and a second layer of a second single material joined to a portion of the first material surface by a semi-solid metal process,
- wherein the first material differs from the second material and the bearing component is configured as one of an inner ring and an outer ring,
- the bearing component having a molecular grain structure formed between the first material and the second material, wherein the molecular grain structure is a result of and associated uniquely with the semi-solid metal process.
A bearing component for a sliding bearing, the bearing component comprising:
- a body formed of a first single material having a first material surface and a layer of a second single material joined to the first material surface by a semi-solid metal process,
- wherein the first material differs from the second material and the bearing component is configured as one of an inner ring and an outer ring,
- wherein the body having a molecular grain structure formed between the first material and the second material, wherein the molecular grain structure is a result of and associated uniquely with the semi-solid metal process.
