Description

Technical Field

[0001] The utility model relates to the field of rolled workpieces, in particular to an offshore wind power bearing outer circular special-shaped hole rolled workpiece. Background Art

[0002] Rolling is a metal processing technology that passes a metal billet through the gap between a pair of rotating rollers. Due to the compression of the rollers, the cross-section of the material is reduced and the length is increased. The rolled piece is pulled between the rotating rollers by friction and is compressed to undergo plastic deformation. Through rolling, the metal has a certain size, shape and properties.

[0003] The rolling of the outer circle of the bearing requires the opening of a special-shaped ring on the outer circle of the bearing to locate the position of the rolling bearing. The bearings used in offshore wind power have a larger diameter and the offshore wind power environment is harsh. If turning is used, the part of the outer circle of the bearing that contacts the workpiece will be turned away, exposing the internal structure and reducing its corrosion resistance. Conventional rolling can only be processed from the edge and cannot process the middle area of ​​the outer circle of the bearing. Utility Model Content
