Embodiment Construction
[0017] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0018] Such as figure 1 As shown, the present invention is a multi-directional connecting angular bearing, which includes a supporting frame, and a rotating cavity with upper and lower openings is arranged in the supporting frame, and the side wall of the rotating cavity has an arc-shaped cross section. A spherical rotating block is embedded in the rotating cavity; on the inner wall of the rotating cavity, two sets of ring-shaped roller arrays are symmetrically arranged relative to the midpoint of the axis, and a ring-shaped roller array is arranged on the side wall of the rotating block. The sliding groove, wherein the width of the sliding groove is greater ...

The invention relates to a multi-directional connecting angular bearing, which comprises a supporting outer frame, and a rotating cavity with upper and lower openings is arranged in the supporting outer frame, and a spherical rotating block is embedded in the rotating cavity; on the inner wall of the rotating cavity, There are two sets of ring-shaped roller arrays arranged symmetrically with respect to the midpoint of the axis, and ring-shaped sliding grooves are arranged on the side wall of the rotating block. The roller array includes a number of balls embedded in the inner wall of the rotating cavity, and the other side of the balls is in contact with the sliding The bottom of the groove is in contact, and a shaft fixing hole is arranged in the middle of the rotating block. A number of expansion holes are arranged in a circular array on the inner wall of the rotating block corresponding to the shaft fixing hole. The expansion holes include a threaded section and an expansion section. The top of the threaded section is rotating One axial side of the block is open, and the expansion section communicates with the bottom of the threaded section. The expansion section is a tapered expansion slide hole, and a tapered expansion block with a length shorter than the expansion slide hole is arranged in the expansion slide hole. A screw for extruding the expansion block is provided.
Description
technical field [0001] The invention relates to a multidirectional connecting angular bearing, which belongs to the field of yaw shaft structures. Background technique [0002] When the shaft is driven, sometimes because the bearing support member and the shaft are not at a perpendicular angle, the fixing hole of the bearing also needs to be opened obliquely, and the wall thickness of the obliquely opened bearing installation hole is uneven, and the wall surface of some installation holes is thin , 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. Contents 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 multi-directional connecting angular bearing. [0004] The technical solution adopted by the ...
