Abstract

The invention discloses a bearing and a bearing lifting hook structure with the bearing. The bearing comprises a first end cap, a second end cap, a support frame which is arranged between the first end cap and the second end cap and is provided with at least two spacing holes, and balls in the spacing holes. The middle of each one of the first end cap, the second end cap and the support frame is provided with an installation through hole. Axes of the installation through holes of the first end cap, the second end cap and the support frame are coincident. The balls press respectively against the first end cap and the second end cap. At least two of the balls are arranged in at least one of the spacing holes. The first end cap can drive the balls to rotate in the spacing holes when the first end cap rotates relatively to the second end cap and around the axes of the through holes. Rotation axes of the balls in the same spacing hole are coincident. The bearing solves the problem of poor flexibility and easy damage of the existing bearing in rotation, and improves bearing and related lifting hook rotation flexibility.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a bearing and a hook structure provided with the bearing. Background technique [0002] The hook is the key component of crawler crane lifting. As the crane is widely used in installation occasions, not only the hook is required to have good bearing capacity, but also the hook is required to have good rotation flexibility, that is, the hook head part of the hook is required to be Can rotate flexibly. The friction coefficient of the bearing used in the hook head part of the hook structure is the main factor affecting the rotation flexibility of the hook. [0003] Such as figure 1 As shown, the bearings used in the existing hook structure are usually thrust spherical roller bearings. The thrust spherical roller bearings include an upper end cover 12 and a lower end cover 13, and the position is between the upper end cover 12 and the lower end cover 13. And a support frame 4 (o...
