Description

Sliding bearing structure

Technical Field

The utility model belongs to a bearing, and particularly relates to a sliding bearing structure.

Background

In the solar tracking bracket, the solar component is fixed with the rotating main beam, and the rotating main beam and the upright post relatively rotate. In order to realize the rotation of the rotating main beam relative to the upright post, the rotating main beam is usually arranged on a bearing, and the bearing is arranged in a bearing box, so that the rotation of the rotating main beam is realized.

However, since the conventional bearing and bearing housing structure is applied to the rotating main beam and the bearing is easily slipped off from the bearing housing, an additional anti-slip member is usually installed to prevent the bearing from slipping off from the bearing housing. As shown in fig. 1 and 2, the rotating main beam is mounted on a single-side flange bearing, the bearing connected to the rotating main beam is mounted in a bearing box, the bearing box is mounted on a stand column, and in order to prevent the bearing from sliding off from the bearing box, a bearing anti-slip baffle is mounted on one side of the bearing, which tends to increase the mounting cost.

Disclosure of Invention

The utility model provides a sliding bearing structure.

The utility model aims to solve the problem that the installation cost is increased due to the fact that an additional anti-slip component is required to be installed in the existing bearing connected with a rotating main beam.

The technical scheme adopted for solving the technical problems is as follows: the sliding bearing structure is characterized by comprising a first bearing sheet and a second bearing sheet, wherein the first bearing sheet and the second bearing sheet are mutually fixed through bolts, a positioning convex shaft and a positioning hole are respectively formed in the inner sides of the first bearing sheet and the second bearing sheet, the positioning convex shaft of the first bearing sheet is inserted into the positioning hole of the second bearing sheet, the positioning convex shaft of the second bearing sheet is inserted into the positioning hole of the second bearing sheet, the first bearing sheet and the second bearing sheet are identical in structure and are single-side flange bearing sheets, and flanges are arranged on the outer sides of the first bearing sheet and the second bearing sheet.

Preferably, screw holes are formed in the first bearing piece and the second bearing piece respectively, and the first bearing piece and the second bearing piece are fixed through nuts after the bolts penetrate through the screw holes of the first bearing piece and the screw holes of the second bearing piece.

Preferably, the outer openings of the screw holes on the first bearing sheet and the second bearing sheet are hexagonal screw cavities, the nuts are hexagonal nuts, and the hexagonal nuts are clamped in the hexagonal screw cavities.

The beneficial effects of the utility model are as follows: the utility model adopts a split flange bearing structure, and can prevent the bearing from falling out of the bearing box body. Secondly, when the bearing is damaged and needs to be replaced, the bearing can be taken out from the bearing box for replacement after being separated, and the maintenance is convenient.

Detailed Description

The utility model will be further described with reference to the drawings and examples.

As shown in the figure, a sliding bearing structure according to the present utility model includes a first bearing sheet 1 and a second bearing sheet 2, the first bearing sheet 1 and the second bearing sheet 2 being fixed to each other by bolts 3. The inner side of the first bearing sheet 1 is provided with a positioning convex shaft 8 and a positioning hole 6, and the symmetrical positions of the inner side of the second bearing sheet 2 and the second bearing sheet 2 are provided with a positioning convex shaft and a positioning hole which are matched. The positioning protruding shaft 8 of the first bearing sheet 1 is inserted into the positioning hole of the second bearing sheet 2, and the positioning protruding shaft of the second bearing sheet 2 is inserted into the positioning hole 6 of the first bearing sheet. The first bearing piece 1 and the second bearing piece 2 have the same structure and are single-side flange bearing pieces, and the outer sides of the first bearing piece 1 and the second bearing piece 2 are respectively provided with a flange 5 and a flange 4.

The first bearing sheet 1 is provided with a screw hole 10, the second bearing sheet 2 is also provided with a screw hole, and the screw hole 10 on the first bearing sheet 1 is opposite to the screw hole on the second bearing sheet 2. The bolt 3 passes through the screw hole 9 of the first bearing sheet 1 and the screw hole of the second bearing sheet 2, and then the first bearing sheet 1 and the second bearing sheet 2 are fixed through the nut 7.

The outer opening of the screw hole 9 of the first bearing sheet 1 is a hexagonal screw cavity 10, and the outer opening of the screw hole of the second bearing sheet 2 is also a hexagonal screw cavity. The nut 7 is a hexagonal nut, and the hexagonal nut is clamped in the hexagonal screw cavity.

The connecting structure for the rotary main beam 11 of the utility model is as follows: the two sliding bearing structures of the utility model have inner rings respectively clamped on the upper side and the lower side of the main rotating beam 11. The flanges of the first bearing sheet 1 and the second bearing sheet 2 of the sliding bearing structure are respectively buckled on two sides of the gear box 12. The first bearing sheet 1 and the second bearing sheet 2 are fixed through bolts 3. In the sliding bearing structure of the present utility model, the flanges of the bearing sheet 1 and the second bearing sheet 2 are respectively fastened to both sides of the gear case 12, so that the sliding bearing structure can be prevented from sliding off from the bearing case.

The existing connection mode of the single-side flange bearing 13 (as shown in fig. 1 and 2) for the rotating main beam 11 is as follows: the single-side flange bearing 13 connected with the rotating main beam 11 is arranged in a bearing box 14, the bearing box 14 is arranged on a stand column 15, and in order to prevent the single-side flange bearing 13 from sliding off from one side of the bearing box 14, a bearing anti-slip baffle 16 is arranged on one side of the single-side flange bearing.
