Abstract
A sliding bearing for a gearbox of a wind turbine, having a support body and a sliding layer which is applied on the support body, and on which a sliding surface is formed, wherein a lubricant distribution groove extending in an axial direction of the sliding surface is formed on the sliding surface. The support body is formed as a bush rolled from a support body strip, wherein a first longitudinal end and a second longitudinal end of the support body strip are connected to one another in a materially bonded manner, in particular by a welding connection, at a joint, wherein the joint is formed in the region of the lubricant distribution groove.
Claims10
A sliding bearing (22), in particular for a gearbox of a wind turbine, having a support body (27) and a sliding layer (30) which is applied on the support body (27), and on which a sliding surface (17) is formed, wherein a lubricant distribution groove (19) extending in an axial direction (31) of the sliding surface (17) is formed on the sliding surface (17), wherein the support body (27) is formed as a bush (35) rolled from a support body strip (32), wherein a first longitudinal end (33) and a second longitudinal end (34) of the support body strip (32) are connected to one another in a materially bonded manner, in particular by a welding connection, at a joint (23), wherein the joint (23) is formed in the region of the lubricant distribution groove (19).
A method for producing a sliding bearing (22), in particular for a gearbox of a wind turbine, wherein the sliding bearing (22) comprises a support body (27) and a sliding layer (30) which is applied on the support body (27), and on which a sliding surface (17) is formed, wherein a lubricant distribution groove (19) extending in an axial direction (31) is formed on the sliding surface (17), comprising the method steps:
- providing a support body strip (32) having a first longitudinal end (33) and a second longitudinal end (34);
- rolling the support body strip (32) to a bush (35), which forms the support body (27);
- establishing a materially bonded connection of the first longitudinal end (33) and the second longitudinal end (34) of the support body strip (32) at a joint (23);
- inserting the lubricant distribution groove (19) into the sliding layer (30), wherein the lubricant distribution groove (19) is arranged at a location on the sliding bearing (22), at which the joint (23) is formed.
