Screw behavior in large diameter slewing bearing asselies: numerical and experimental analyses …

15/3/2007· This paper investigates the behavior of large diameter bearing bolted joint in order to evaluate fatigue resistance of the screws. Based on experimental results, a sector of a slewing bearing is modeled using 3D finite elements. The model is built via hypothesis of sine-distributed efforts on the roller tracks. The simulations are carried out for the most loaded screw, which is …
