Abstract
A bearing assembly includes first and second rolling-element bearings each having first and second bearing rings, a raceway and a flange element at both ends of the raceways. Two of the flange elements are formed on a common flange body, and the flange body is axially pressed onto cylindrical mounting surfaces of the first bearing rings of the first and second rolling-element bearings and held in place by a press fit.
Claims17
A bearing assembly comprising:
- a first rolling-element bearing including a first bearing ring and a second bearing ring, the first bearing ring of the first rolling-element bearing including a raceway axially delimited by a first flange element and a second flange element,
- a second rolling-element bearing disposed axially adjacent to the first rolling-element bearing, the second rolling-element bearing including a first bearing ring and a second bearing ring, the first bearing ring of the second rolling-element bearing including a raceway axially delimited by a first flange element and a second flange element,
- wherein the first flange element of the first bearing ring of the first rolling-element bearing and the first flange element of the first bearing ring of the second rolling-element bearing are formed on a common flange body, the common flange body being mounted on the first bearing ring of the first rolling-element bearing and on the first bearing ring of the second rolling-element bearing, and
- wherein the first bearing ring directly contacts the second bearing ring at a joint.

A method for manufacturing a bearing assembly comprising:
- providing a first bearing ring having a raceway, a first flange element at a first end of the raceway and a cylindrical mounting surface at a second end of the raceway,
- providing a second bearing ring having a raceway, a first flange element at a first end of the raceway of the second bearing ring and a cylindrical mounting surface at a second end of the raceway of the second bearing ring,
- pressing an annular common flange body axially onto the cylindrical mounting surface of the first bearing ring to form a press fit;
- pressing the cylindrical mounting surface of the second bearing ring axially into the annular common flange body until the second bearing ring abuts the first bearing ring,
- forming a second flange element of the first bearing ring at a first axial side of the common flange body and forming a second flange element of the second bearing ring at a second axial side of the common flange body, and
- post-processing the common flange body and the first bearing ring and the second bearing ring.
