Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a novel tracking support bearing seat structure. Background Technology

[0002] In photovoltaic tracking brackets, the current mainstream bearing design uses a spherical structure to adapt to different slopes. However, this structure has a certain drawback: at slightly larger angles, under vibration, the spherical bearing is prone to misalignment, causing it to easily come off. Therefore, the only solution is to reduce the adaptable slope and increase the width of the spherical bearing to avoid this situation. Secondly, traditionally, when cables pass through the bearing housing, they are pre-positioned on the outside of the bearing housing, allowing them to dangle freely. When the spindle rotates, the cables will rub against the bearing housing and cause damage. Utility Model Content

[0003] To address the aforementioned technical problems, a novel tracking bracket bearing housing structure is provided.

[0004] To achieve the above objectives, this utility model discloses a novel tracking bracket bearing housing structure, including a bearing bracket and a spherical bearing disposed within the bearing bracket. The bearing bracket includes a bearing housing and a bearing cover disposed above the bearing housing. The bearing housing is fixed to the top of a mounting plate, and the two ends of the bearing cover are correspondingly connected to the two ends of the mounting plate. The spherical bearing is composed of at least two sets of split bearings and is disposed inside the bearing bracket along the circumferential direction of the inner end face of the bearing bracket. A through-hole for inserting a spindle is opened at the center of the spherical bearing, and cable ports are opened on the spherical bearings on both sides of the through-hole. Bearing flanges extending along the spindle direction are symmetrically arranged on the end face of the bearing cover, and bearing flash is provided on the split bearings between the bearing flanges on the same side.

[0005] Furthermore, the bearing housing is embedded in the top of the mounting plate and fixed by rivets, and the inner end face of the bearing housing and the bearing cover is a spherical structure that matches the surface of the spherical bearing.

[0006] Furthermore, the two ends of the bearing cover are connected to the two ends of the mounting plate by means of pins.

[0007] Furthermore, the bearing retainers are respectively provided on both end faces of the bearing cover, and two sets are symmetrically provided on the same side. The bearing retainers extend outward along the arc of the inner end face of the bearing cover, and the extension direction of the bearing retainers is biased towards the bearing flash on the corresponding side of the split bearing.

[0008] Furthermore, the angle α between the center point of the bearing flange on the same side and the line connecting the center of the spindle is in the range of 90° to 180°.

[0009] Furthermore, the bearing flash is symmetrically arranged on both sides of the split bearing, and is located on the front and rear sides of the bearing bracket respectively, with the bearing flash bending toward the bearing bracket side of the corresponding side.

[0010] Furthermore, the spindle is inserted into the through-hole of the spherical bearing along the X-axis direction and rotates together with the spherical bearing in multiple angular directions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a novel tracking bracket bearing seat structure. By adding two limiting elements, the bearing flash and the bearing stop, to the bearing, the defect of the spherical bearing coming off after misalignment is solved at any allowable angle.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the bearing bracket 1 includes a bearing seat 11 and a bearing cover 12 disposed above the bearing seat 11. The bearing seat 11 is fixed to the top of the mounting plate 2. The two ends of the bearing cover 12 are correspondingly connected to the two ends of the mounting plate 2. The spherical bearing 3 is composed of at least two sets of split bearings 30 and is disposed inside the bearing bracket 1 along the circumferential direction of the inner end face of the bearing bracket 1. The center of the spherical bearing 3 has a through-hole for the spindle 4 to be inserted. Cable ports 31 are provided on both sides of the through-hole on the spherical bearing 3, through which cables can pass. When the bearing rotates, the cable keeps synchronous with the spindle to prevent the cable from being damaged by friction with the bearing seat. The bearing cover 12 has symmetrical bearing flanges 121 extending along the direction of the spindle 4 on its end face. The split bearings 30 between the bearing flanges 121 on the same side are provided with bearing flash 32. With the center of the spherical bearing as the origin, the X-axis is defined along the length of the main shaft, and the Y-axis is defined perpendicular to the horizontal plane. When rotating to its maximum angle around the X-axis, the bearing retainer on the edge of the bearing cover mechanically limits the spherical bearing to prevent excessive rotation and reduce large-scale swaying caused by wind vibration in windy weather, thus protecting the safety of the components and the support. When rotating around the Y-axis, the bearing flash contacts the side of the bearing cover to prevent the spherical bearing from misaligning and coming off. By adding two limiting elements, the bearing flash and the bearing retainer, the defect of the spherical bearing coming off after misalignment is solved at any permissible angle. At the same time, it can prevent excessive rotation and large-scale swaying in strong winds. A cable port is designed so that the cable can rotate synchronously with the main shaft to prevent friction with the bearing seat.

[0023] The bearing housing 11 is embedded in the top of the mounting plate 2 and fixed by rivets. The inner end face of the bearing housing 11 and the bearing cover 12 is a spherical structure that matches the surface of the spherical bearing 3. The two ends of the bearing cover 12 are connected to the two ends of the mounting plate 2 by pins, which is convenient for installation and ensures connection stability.

[0024] Bearing flanges 121 are respectively provided on both end faces of the bearing cover 12, and two sets are symmetrically provided on the same side. The bearing flanges 121 extend outward along the arc of the inner end face of the bearing cover 12. The extension direction of the bearing flanges 121 is biased towards the bearing flash 32 on the corresponding side split bearing 30. The angle between the center point of the bearing flanges 121 on the same side and the center of the main shaft 4 is the rotation range of the spherical bearing with the X-axis as the rotation axis. In this embodiment, α is 90°. The bearing flanges mechanically limit the spherical bearing to prevent excessive rotation and reduce the large swing caused by wind vibration in windy weather, thus protecting the safety of the components and the support.

[0025] The bearing flash 32 is symmetrically arranged on both sides of the split bearing 30, and is located on the front and rear sides of the bearing bracket 1 respectively. The bearing flash 32 is bent toward the bearing bracket 1 on the corresponding side, and the bending position prevents the spherical bearing from being misaligned and dislodged.

[0026] The spindle 4 is inserted into the through-hole of the spherical bearing 3 along the X-axis and rotates together with the spherical bearing 3 in multiple angular directions. By adding two limiting elements, the bearing flash and the bearing retainer, to the bearing, the defect of the spherical bearing coming out after misalignment is solved at any permissible angle.
