ActiveCN103420287AReasonable forceReasonable force structureCranesArchitectural engineeringSlewing bearing
The invention discloses a slewing bearing structure of a crane. The structure comprises a support case, an inner cylinder, an outer cylinder, mounting plates and a cover plate. The end face of the support case is a connection board, and the bottom of the support case is a base plate. One end of the inner cylinder is welded with the base plate, and the other end of the inner cylinder is welded with the cover plate. One end of the outer cylinder is welded with the connection board, and the other end of the outer cylinder is welded with the cover plate. The mounting plates are symmetrically arranged in the support case, and the distance from the mounting plates to the inner cylinder is greater than the distance from the outer cylinder to the inner cylinder. As the distance from the mounting plates to the inner cylinder is greater than the distance from the outer cylinder to the inner cylinder, when the mounting plates and the inner cylinder are welded on the base plate of the support case, the welding deformation is reduced obviously. When the slewing bearing structure is applied with force, as the distance between the mounting plates and the inner cylinder is large, the base plate uniformly disperses the applied pressure, thereby realizing more reasonable bearing on the base plate.
