Embodiment Construction

[0016] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0017] Such as figure 1 As shown, the present invention is a pendulum bearing, including a support outer frame, a rotating cavity with upper and lower openings is arranged in the support outer frame, and the cross section of the side wall of the rotating cavity is arc-shaped. A spherical rotating block is embedded in the rotating cavity; on the inner wall of the rotating cavity, two ring-shaped roller arrays are arranged symmetrically with respect to the center of the axis, and an annular sliding block is arranged on the side wall of the rotating block. Groove, wherein the width of the sliding groove is greater than the distance between the two sets of roller arrays, t...

Abstract

The invention relates to a pendulum bearing, which includes a supporting frame, and a rotating cavity with upper and lower openings is arranged in the supporting frame, the side wall of the rotating cavity has an arc-shaped cross section, and a spherical Rotating block; on the inner wall of the rotating cavity, two sets of annular roller arrays are symmetrically arranged relative to the midpoint of the axis, and an annular sliding groove is arranged on the side wall of the rotating block, wherein the width of the sliding groove is larger than that of the two sets of rollers. The spacing of the sub-arrays, the roller array includes a number of balls embedded in the inner wall of the rotating cavity, the other side of the balls is in contact with the bottom of the sliding groove, and a shaft fixing hole is arranged in the middle of the rotating block. The present invention uses a bearing inner frame and The outer frame has a pendulum bearing with a certain swing range to realize the variable angle rotation connection between the shaft rod and the shaft seat. Compared with opening inclined holes on the shaft seat, this structure only needs vertical holes to realize the shaft multi-angle rotation connection.

Description

Technical field [0001] The invention relates to a pendulum bearing, which belongs to the field of yaw shaft structure. Background technique [0002] During shaft transmission, sometimes the bearing fixing hole needs to be opened obliquely because the bearing support member and the shaft are not at a perpendicular angle, and the wall thickness of the obliquely opened bearing installation hole is uneven, and the wall surface of some of the installation holes is thinner , It is easy to rupture due to excessive radial pressure, and the accuracy of the axis of the inclined bearing mounting hole is also difficult to guarantee. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical problem of poor reliability of the oblique opening of the bearing fixing hole in the prior art and provide a pendulum bearing. [0004] The technical solutions adopted by the present invention to solve its technical problems are: [0005] A pend...
