If the photovoltaic tracking system generates displacement at the top of the post in the later period, or the hoop and the main shaft are relatively displaced due to the increase of the axial force, the bearing is relatively separated from the bearing seat, the stress of the bearing is increased, and the abrasion of the bearing is increased. The service life of the bearing is shortened, the bearing is damaged in advance, the normal operation of a photovoltaic tracking system is influenced, and great economic loss is brought; and the installation steps are complex, and the installation cost and the structural cost are high.

2. The existing traditional bearing structure parts are mostly split, the bearing is limited by the hoop, the overall performance is poor, the strength is not guaranteed well, the bearing is not reliable, and the risk of great economic loss caused by the whole unit or even the whole power station is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of prior art, provide a reasonable in design, compact structure's bearing of being applied to photovoltaic tracking system.

The utility model discloses a realize through following technical scheme: a bearing applied to a photovoltaic tracking system is composed of a bearing body and is characterized in that the bearing body comprises two single-side flange bearings which are oppositely combined together; the single-side flange bearings combined together relatively are clamped on the inner wall of the bearing ring on the integrated bearing seat.

The single-side flange bearing is formed by an arc-shaped body, an inner groove is formed in the middle of the arc-shaped body, and a vertical extending edge perpendicular to the outer wall of the single-side flange bearing is arranged at the outer edge of the single-side flange bearing.

The radian of the outer wall of the unilateral flange bearing is equivalent to that of the inner wall of the bearing ring, the outer wall of the unilateral flange bearing is attached to the inner wall of the bearing ring for installation, and the unilateral flange bearing is limited through a vertical extension edge arranged on the edge of the unilateral flange bearing.

And the plane surface of the unilateral flange bearing is also provided with a fastening hole, and a bearing baffle is arranged on the fastening hole.

The integrated bearing pedestal consists of a bearing ring and a U-shaped base, and the bearing ring is fixed on the base in a three-dimensional manner.

The beneficial effects of the utility model reside in that: compared with the prior art, the utility model discloses the bearing adopts unilateral flange structure, and during the installation tracker girder, the bearing pushed the installation from the unilateral, and the structural style that the opposite side adopted the baffle passes through the fastener to be installed on the bearing, guarantees that the bearing both sides homoenergetic receives spacingly. Simple structure, it is convenient to install.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In a first embodiment, please refer to fig. 3 to 6, a bearing applied to a photovoltaic tracking system is composed of a bearing body, wherein the bearing body includes two unilateral flange bearings 4 which are oppositely combined together; the single-sided flange bearings 4 combined oppositely are clamped on the inner wall of the bearing ring 301 on the integrated bearing seat 3 together.

The integrated bearing seat 3 comprises a bearing ring 301 and a U-shaped base 302; the bearing ring 301 is fixed three-dimensionally on a U-shaped base 302. The integrated bearing housing 3 is mounted on the column connection piece 2 by means of bolts. The two single-sided flange bearings 4 are symmetrically clamped against the inner ring wall of the bearing ring 301.

The single-side flange bearing 4 is formed by an arc-shaped body, an inner groove 404 is formed in the middle of the arc-shaped body, the inner groove 404 is set to be a square groove according to the shape of the main shaft 6, the main shaft 6 is convenient to install, and a vertical extending edge 401 perpendicular to the outer wall of the single-side flange bearing 4 is arranged on the outer edge of the single-side flange bearing 4.

The radian of the outer wall 402 of the single-side flange bearing is equivalent to that of the inner wall of the bearing ring 301, the outer wall 402 of the single-side flange bearing is attached to the inner wall of the bearing ring 301 for mounting and clamping, and the clamping is carried out through the vertically extending edge 401 arranged on the edge of the single-side flange bearing 4 for limiting.

The plane surface of the unilateral flange bearing 4 is also provided with a fastening hole 403 for installing a bearing baffle 5 on a plane, and the bearing baffle 5 plays a reliable limiting role in the rotation of the unilateral flange bearing 4.
