Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more particularly to a bearing stop and a photovoltaic bracket. Background Technology

[0002] In existing photovoltaic systems, split-type bearings are widely used in the main shaft support components due to their ease of installation and maintenance. Split-type bearings typically consist of two or more arc-shaped components that fit together on the main shaft, creating a gap around the shaft. While this design facilitates installation and maintenance, it also presents some problems. During shaft rotation, the gap between the split-type bearing and the main shaft can cause displacement, leading to the bearing not rotating with the shaft. When the bearing deviates from the main shaft, torque is generated between the bearing and the main shaft. Furthermore, since the bearing and bearing housing are not concentric and not perpendicular to the column top mount, the column top mount experiences a greater reaction force, and the force distribution is uneven. When the force on the column top mount is less than the force on the main shaft, the column top mount will be damaged, thus reducing its service life.

[0003] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content

[0004] The purpose of this application is to provide a bearing retainer and a photovoltaic bracket that can limit the relative displacement between the main shaft and the split bearing, reduce the possible offset of the split bearing during the rotation of the main shaft, and improve the rotational following ability of the split bearing.

[0005] The technical solution provided by this utility model is as follows:

[0006] A bearing retainer is suitable for mounting a spindle with a split bearing, the split bearing comprising a first bearing portion and a second bearing portion, including:

[0007] The mounting part and the abutment part connected to the mounting part;

[0008] The mounting part is used to connect with the spindle so that the bearing retainer is installed on the outer wall of the spindle and located in the gap formed by the first bearing part and the second bearing part on the periphery of the spindle;

[0009] The abutting part is adapted to abut against the side of the first bearing part and the second bearing part that are close to each other, so as to restrict the first bearing part and the second bearing part from moving circumferentially along the main shaft.

[0010] In some embodiments, the abutting portion includes two spaced-apart abutting plates, with the sides of the two abutting plates that are far apart from each other being used to abut against the sides of the first bearing portion and the second bearing portion that are close to each other.

[0011] In some embodiments, the bearing stop also includes:

[0012] The connecting part is used to connect the mounting part and the two abutment plates.

[0013] In some embodiments, the connecting portion has a plate-like structure and is located at the ends of the two abutting plates, forming a U-shaped structure together with the two abutting plates; and,

[0014] The mounting part has a plate-like structure, with one end located on the edge of the connecting part between the two abutting plates, and the other end extending toward the opening side of the U-shaped structure.

[0015] In some embodiments, the ends of the two abutment plates away from the connecting portion are bent toward each other to form a first retaining edge, which is adapted to abut against the axial ends of the first bearing portion and the second bearing portion to restrict the first bearing portion and the second bearing portion from moving axially along the main shaft.

[0016] In some embodiments, a second stop extending toward the connecting part is provided on the side of the first stop away from the mounting part, which is adapted to abut against the outer side wall of the first bearing part and the second bearing part to restrict the first bearing part and the second bearing part from moving radially along the main shaft.

[0017] In some implementations, the abutment plate, the connecting part, and the mounting part are integrally formed.

[0018] In some embodiments, the mounting part has a mounting hole for fasteners to pass through in order to lock the mounting part to the spindle.

[0019] This application also provides a photovoltaic mounting bracket, comprising:

[0020] Spindle, bearing assembly, and bearing stop provided in any of the above embodiments;

[0021] The bearing assembly includes a bearing housing and a split bearing. The bearing housing has a bearing hole, and the split bearing is installed in the bearing hole. The split bearing includes a first bearing part and a second bearing part, and the first bearing part and the second bearing part together form a through hole. The spindle passes through the through hole so that the spindle can rotate relative to the bearing housing.

[0022] The outer wall of the main shaft is equipped with a bearing stop, which is located between the first bearing part and the second bearing part and abuts against the side of the first bearing part and the second bearing part that are close to each other, so as to restrict the first bearing part and the second bearing part from moving circumferentially along the main shaft.

[0023] In some embodiments, the split bearing has two gaps on the circumference of the spindle. Each gap is equipped with two bearing stops, and the ends of the two bearing stops that are far apart from each other extend toward the first bearing portion and the second bearing portion to form a first stop edge. The first stop edges of the two bearing stops abut against the two ends of the first bearing portion and the second bearing portion in the axial direction, respectively, to restrict the first bearing portion and the second bearing portion from moving axially along the spindle.

[0024] The technical advantages of this application are as follows:

[0025] 1. This application, by setting a bearing retainer and installing it on the outer wall of the main shaft, with its abutting portion abutting against the first and second bearing portions of the split bearing respectively, can effectively limit the relative displacement between the main shaft and the split bearing, reducing the possible offset of the split bearing during the rotation of the main shaft, and facilitating the rotation of the split bearing. Simultaneously, by limiting the offset of the split bearing, the bearing retainer ensures that the split bearing is concentric with the bearing housing and located in the same vertical direction as the column top seat, extending the service life of the column top seat. During the rotation of the main shaft, the bearing retainer installed on the main shaft also promotes the rotation of the split bearing, further enhancing the rotational capability of the split bearing, ensuring that the photovoltaic bracket can accurately drive the photovoltaic modules to follow the sun's movement, resulting in faster response and better performance.

[0026] 2. In this application, the abutting part includes two abutting plates, which are connected by a plate-shaped connecting part to form a U-shaped structure. One end of the mounting part is also connected to the connecting part, and the other end extends towards the opening side of the U-shaped structure. The bearing stop can be installed by locking the mounting part to the main shaft with fasteners. The bearing stop in this application has a simpler and lighter overall structure, and can achieve lightweight production of the bearing stop without affecting its use, resulting in low production costs.

[0027] 3. In this application, the abutment plate is bent to form a first stop edge that abuts against the axially upward end of the first bearing portion and the second bearing portion. Furthermore, the first stop edge is provided with a second stop edge that abuts against the outer wall of the first bearing portion and the second bearing portion. The first stop edge, the second stop edge, and the abutment plate together can limit the position of the split bearing in the axial, radial, and circumferential directions, preventing relative displacement between the split bearing and the spindle. In addition, the first stop edge, the second stop edge, and the abutment plate can collectively form a structure that fits the corners of the first bearing portion and the second bearing portion, enabling quick positioning during installation, resulting in better and faster installation.

[0046] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figures 1 to 4 A bearing stop 100 is provided for mounting a spindle 500 with a split bearing 200. The split bearing 200 may specifically include a first bearing portion 210 and a second bearing portion 220. The bearing stop 100 includes a mounting portion 110 and an abutment portion connected to the mounting portion 110. The mounting portion 110 is used to engage with the spindle 500, such that the bearing stop 100 is mounted on the outer wall of the spindle 500 and located in the gap formed by the first bearing portion 210 and the second bearing portion 220 on the periphery of the spindle 500. The abutment portion is adapted to abut against the side of the first bearing portion 210 and the second bearing portion 220 that are close to each other, thereby restricting the circumferential movement of the first bearing portion 210 and the second bearing portion 220 relative to the spindle 500.

[0047] The bearing stop 100 provided in this embodiment serves as an auxiliary installation structure, positioned in the gap formed by the first bearing portion 210 and the second bearing portion 220 around the spindle 500. The abutment portion on the bearing stop 100 abuts against the sides of the first bearing portion 210 and the second bearing portion 220 that are close to each other, filling the gap and ensuring the overall structural strength and stability. Especially during the rotation of the spindle 500, the bearing stop 100 restricts relative displacement between the first bearing portion 210 and the second bearing portion 220 around the spindle 500, preventing the split bearing 200 from shifting relative to the spindle 500. This ensures that the split bearing 200 is concentric with the bearing housing 300 and located in the same vertical direction as the column top seat 400, extending the service life of the column top seat 400.

[0048] Furthermore, when the bearing stop 100 restricts the circumferential displacement of the first bearing portion 210 and the second bearing portion 220 relative to the main shaft 500, it also helps the split bearing 200 to rotate. Moreover, during the rotation of the main shaft 500, the bearing stop 100 can also push the first bearing portion 210 and the second bearing portion 220 to rotate together, further improving the rotational capability of the split bearing 200, ensuring that the photovoltaic bracket can accurately drive the photovoltaic module to follow the sun's movement, with faster response speed and better performance.

[0049] Furthermore, the first bearing portion 210 and the second bearing portion 220 will mostly form two gaps around the spindle 500. At this time, two bearing stops 100 can be installed and inserted into the two gaps respectively, and the bearing stops 100 can be installed on the spindle 500 via the mounting portion 110.

[0050] In another embodiment, the first bearing section 210 includes two first split bearings, and the second bearing section 220 includes two second split bearings. The two first split bearings and the two second split bearings form four gaps around the spindle 500. In this case, four bearing stops 100 are respectively inserted into the four gaps. The abutting part provided on the bearing stop 100 can abut against the side of the two first split bearings and the two second split bearings that are close to each other, so as to fill the gaps and prevent the split bearing 200 from shifting relative to the spindle 500.

[0051] Specifically, the abutment part can be a block-shaped structure that can be inserted into the gap between the first bearing part 210 and the second bearing part 220. In this case, the mounting part 110 is a plate-shaped structure that extends axially from one end of the abutment part and can fit against the outer wall of the spindle 500 and be locked to the spindle 500 by fasteners.

[0052] In one example embodiment, see 2 to Figure 4The abutting part may also include two spaced abutting plates 120. The sides of the two abutting plates 120 that are far apart from each other are used to abut the sides of the first bearing part 210 and the second bearing part 220 that are close to each other. Compared with the overall block structure, this structure is lighter and more conducive to the lightweight production of the bearing stop 100. At the same time, less material is required for production, resulting in lower cost.

[0053] At this time, the two abutment plates 120 can be directly connected to the mounting part 110, and the mounting part 110 is preferably plate-shaped, fitting against the outer wall of the main shaft 500, and can be locked to the main shaft 500 by fasteners. Alternatively, other structures can be provided to achieve the connection between the two abutment plates 120 and the mounting part 110.

[0054] For example, see Figure 2 and Figure 3 In one specific embodiment, the bearing stop 100 further includes a connecting portion 130 for connecting the mounting portion 110 and the two abutment plates 120. The connecting portion 130 is preferably plate-shaped and located at the ends of the two abutment plates 120, forming a U-shaped structure together with the two abutment plates 120. The mounting portion 110 is also preferably plate-shaped, with one end located at the edge of the connecting portion 130 between the two abutment plates 120, and the other end extending towards the opening side of the U-shaped structure.

[0055] The bearing retainer 100 provided in this embodiment has higher structural strength and better structural stability compared to the structure of directly installing two abutment plates 120 onto the mounting part 110, without significantly increasing the cost. It also ensures lightweight production of the bearing retainer 100, and the overall structural design is more reasonable and reliable. Preferably, the abutment plates 120, the connecting part 130, and the mounting part 110 are manufactured using an integral molding process, which facilitates processing, is beneficial for mass production, and has strong practicality.

[0056] Preferably, see Figures 2 to 4The ends of the two abutment plates 120 away from the connecting part 130 are bent towards each other to form first retaining edges 121, which are suitable for abutting the axial ends of the first bearing part 210 and the second bearing part 220 to restrict the axial movement of the first bearing part 210 and the second bearing part 220 relative to the main shaft 500. In practical applications, four bearing retainers 100 should be provided between the first bearing part 210 and the second bearing part 220. The four bearing retainers 100 are arranged in pairs at two gaps, and the two bearing retainers 100 corresponding to each gap should be arranged back to back so that the first retaining edges 121 on the two bearing retainers 100 can abut the two ends of the first bearing part 210 and the second bearing part 220 in the axial direction, thereby effectively restricting the relative axial movement between the split bearing 200 and the main shaft 500, improving stability, and further extending the service life of the column top seat 400.

[0057] Of course, in actual production, first baffles can also be set at both ends of the two abutment plates 120, and a bearing stop 100 can be set at the gap between the first bearing part 210 and the second bearing part 220 to limit the axial ends of the first bearing part 210 and the second bearing part 220. However, this structure is more difficult and complicated to install than the structure with only one end having a first baffle 121, as the insertion problem of the bearing stop 100 needs to be considered. The bearing stop 100 with only one end having a first baffle 121 can be installed by simply inserting the ends of the two bearing stops 100 without the first baffle 121 into the gap from both ends of the split bearing 200 in the axial direction, and then locking the mounting part 110 to the main shaft 500. The operation is convenient and quick, and the overall structure is better.

[0058] Furthermore, a second stop 122 extending toward the connecting portion 130 is provided on the side of the first stop 121 away from the mounting portion 110, which is adapted to abut against the outer side wall of the first bearing portion 210 and the second bearing portion 220 to restrict the first bearing portion 210 and the second bearing portion 220 from moving radially along the main shaft 500.

[0059] This embodiment, by further providing a second retaining edge 122, in conjunction with the abutment plate 120 and the first retaining edge 121, can limit the split bearing 200 in the radial, circumferential, and axial directions, further improving the stability of the overall structure and extending the service life of the column top seat 400. Furthermore, the abutment plate 120, the first retaining edge 121, and the second retaining edge 122 can form a structure that adapts to the contours of the corners (bearing shoulders) of the first bearing portion 210 and the second bearing portion 220, enabling rapid positioning during installation, resulting in better and faster installation.

[0060] The above embodiments mainly illustrate the structural arrangement of the first stop 121 and the second stop 122 when the abutting part includes two abutting plates 120. If the abutting part is a block structure, the first stop 121 can also be provided on one end of the abutting part opposite to both sides to abut against one end of the first bearing part 210 and the second bearing part 220 in the axial direction. Then, the second stop 122 is provided on the first stop 121 to abut against the outer side wall of the first bearing part 210 and the second bearing part 220. Further details are omitted here, and all are within the protection scope of this application.

[0061] Specifically, in all the above embodiments, the mounting part 110 has a mounting hole 111 for fasteners to pass through, so as to lock the mounting part 110 to the spindle 500. The fastener is preferably a self-tapping screw, which can tap its own threads in metal or non-metal materials without pre-drilling or tapping, and can be directly screwed into the spindle 500, simplifying the installation process.

[0062] See Figure 1 and Figure 2 This application also discloses a photovoltaic bracket, including a main shaft 500, a bearing assembly, and a bearing stop 100 provided in any of the above embodiments. The bearing assembly includes a bearing housing 300 and a split bearing 200. The bearing housing 300 has a bearing hole, and the split bearing 200 is installed in the bearing hole. The split bearing 200 includes a first bearing portion 210 and a second bearing portion 220, and the first bearing portion 210 and the second bearing portion 220 together surround a through hole, through which the main shaft 500 passes, so that the main shaft 500 can rotate relative to the bearing housing 300. At this time, the aforementioned bearing stop 100 is installed on the outer wall of the main shaft 500. The bearing stop 100 is located between the first bearing part 210 and the second bearing part 220, and abuts against the side where the first bearing part 210 and the second bearing part 220 are close to each other, so as to restrict the first bearing part 210 and the second bearing part 220 from moving around the main shaft 500, avoid the main shaft 500 from shifting, and improve the rotational capability of the split bearing 200.

[0063] Further, see Figure 2The split bearing 200 has two gaps around the main shaft 500. Each gap is equipped with two bearing stops 100. The ends of the two bearing stops 100 that are far apart from each other extend toward the first bearing portion 210 and the second bearing portion 220 to form first flanges 121. The first flanges 121 of the two bearing stops 100 abut against the two ends of the first bearing portion 210 and the second bearing portion 220 in the axial direction, respectively, to restrict the first bearing portion 210 and the second bearing portion 220 from moving axially along the main shaft 500. The first flanges 121 can be further provided with second flanges 122, which can abut against the outer walls of the first bearing portion 210 and the second bearing portion 220, so that the bearing stops 100 can limit the split bearing 200 in the circumferential, axial and radial directions, resulting in better stability and extending the service life of the column top seat 400.

[0064] In one specific embodiment, the photovoltaic support also includes multiple columns and purlins. The multiple columns are arranged sequentially at intervals along a straight line, and each column has a column top seat 400 at its top for connecting to the bearing assembly. The main shaft 500 passes sequentially through the split bearings 200 on the multiple column top seats 400, and the multiple purlins are sequentially installed on the main shaft 500 for mounting photovoltaic modules. The main shaft 500 can rotate relative to the bearing seat 300 within the split bearings 200, thereby driving the purlins and photovoltaic modules to rotate synchronously. By setting a bearing stop 100 as an auxiliary installation structure, located in the gap formed by the split bearings 200 around the main shaft 500, it is beneficial to improve the rotational capability of the split bearings 200, improve the response speed of the photovoltaic support, and ensure that the photovoltaic support can accurately drive the photovoltaic modules to follow the movement of the sun.

[0065] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0066] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
