| Abstract: | Ladle rotating tower is the key equipment of caster, and the slewing bearing is its important part. And that if the connecting bolts of the slewing bearing are tightened is directly related to the work life of the bearing. It is calculated the pre - tightening force of the bolt, analyzed the deformation of the bolt with finite element method. It is proved in practice that the calculated pre - tightening force can guarantee the normal operation and longer life of the bearing. |
