Problems solved by technology

This has the result that, for example, the inclined position of the raceways provided as raceway corrections is no longer suitable if the bearing ring is no longer properly deformed in the region of the cutouts or weakenings of the connecting structure due to the lower bending loads

Embodiment Construction

[0038] Such as figure 1 and figure 2 As shown, the rolling bearing 1 may have two rolling loops 2 and 3 that are concentrically concentrically, wherein the rolling bearing 1 may be a rotating mechanism bearing, for example, as a crane 21 or other material handling or construction machinery ( Turning mechanism bearings in tower cable excavators or marine cranes or port cranes. Such as Figure 4 As shown, the rolling bearing 1 can, for example, support the upper structure of the crane to support the vertically rotating mechanism axis 18 in the lower structure, and the lower structure can be constructed, for example, in the form of a truck. The cantilever 22 can be supported on the upper structure, such as a load pickup device 23 in the form of a load hook extends from the cantilever and can rise or decrease. The hanging arm 22 may be expandable and / or tilted and having an extension portion such that the load pickup device and the load on which the boom 22 itself has a lever arm wit...

Abstract

The invention relates to a rolling bearing having two concentric rolling rings which are rotatably supported by at least one row of rolling bodies and have a raceway for the rolling bodies of the at least one row of rolling bodies, and to a material handling and / or construction machine having such a rolling bearing, such as a crane or a tower cable excavator. According to the invention, different raceway modifications are provided in different angular sectors of the rolling ring and / or raceway modifications are provided only in a fraction of the circumference of the rolling ring.

Description

[0001] Inventive field [0002] The present invention relates to a rolling bearing having two rolling rolling loops with each other, the rolling ring rotatably supported by at least one rolling body and has a roller for the at least one rolling body of the rolling body, And involving a material handling and / or construction machine with such a rolling bearing, such as a crane or tower cable excavator. Background technique [0003] In the rolling bearing mounted in large or highly loaded structures (e.g., cranes), in addition to the axial force and / or radial force, a high bending torque and a tilt load are typically occurred, which acts on the bearing ring and may It causes the rotation and rolling ring to be offset from each other, so that it is possible to have an early wear in the region of the rolling ring and the rolling. For example, a diameter can be used for a few meters or a large rolling bearing can be used on a crane or tower cable excavator for, for example, rotatably...
