Analysis of Bulging Application in the Wind Power Bearing Ring Production

Abstract:

Bearing is the core components of wind power equipment. According to the special requirement of high reliability, long life of wind power bearing, the current manufacturing defects of it has been analyzed, such as flange, pits, fish-tail, folding, and comparing with its current manufacturing method, which is called ring rolling, therefore, a new method called rolling and bulging-matching techniques is proposed, as wind power bearing ring should be released stress after rolling, then sized through bulging and once again to stress. Ring bulging is still a blank space in China; this project plans to research bulging process kinematics and dynamics analysis first. This paper gives a brief introduction of bulging processing and focus on the analysis of wind power bearing ring bulging forming.
