Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and further to a bearing assembly and a photovoltaic tracking bracket. Background Art

[0002] Currently, the main shaft bearings of photovoltaic racks typically utilize split-section, double-shoulder bearing assemblies.

DETAILED DESCRIPTION

[0039] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0041] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0042] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] Most existing bearing structures on the market utilize a split, double-shoulder bearing design. During actual operation, these bearings are prone to relative sliding between the spindle and the bearing due to design clearances, resulting in reduced tracking accuracy. Furthermore, prolonged operation can easily lead to wear of the bearing shoulders, especially when bearing nodes are offset from tolerance. This wear problem is exacerbated by the bearing's service life, increasing maintenance costs and workload. Furthermore, if replacement is necessary, the existing split design complicates the on-site replacement process, typically requiring complete replacement. This not only increases maintenance costs but also increases workload complexity.

[0046] This application aims to solve the problems in the prior art. Figure 1 The bearing assembly and photovoltaic tracking bracket provided in this application can effectively reduce the wear problem caused by offset tolerance, extend the service life of the bearing, and simplify the on-site maintenance and replacement process, thereby reducing maintenance costs and improving the operating efficiency and service life of the photovoltaic bracket.

[0047] Reference Manual Figure 1 The present application provides a bearing assembly, including a bearing body and a limiter 3. Specifically, Figure 3 and Figure 4 As shown, the bearing body has an installation space running through its axial direction for installing the main shaft 4 of the photovoltaic bracket. The outer peripheral wall of the bearing body protrudes radially to form a shoulder, which can play a role in positioning and supporting during the operation of the bearing.

[0048] Furthermore, the bearing body includes a first bearing body 11 and a second bearing body 12 that are matched with each other. The two shaft bodies are connected by a mortise and tenon structure 2, and together constitute a mating surface adapted to the outer peripheral wall of the main shaft 4, ensuring a firm fit between the bearing body and the main shaft 4, and providing excellent positioning and fixing capabilities for the bearing.

[0049] Among them, the use of the mortise and tenon structure 2 can ensure the precise fit and coaxiality between the bearing body and the main shaft 4, thereby significantly reducing the gap between the two; at the same time, due to the self-locking characteristics of the mortise and tenon structure 2, it can also compensate to a certain extent for dimensional changes caused by manufacturing errors or thermal expansion and contraction of materials, further ensuring the stability and reliability of the bearing in long-term operation.

[0050] Another significant advantage of the mortise and tenon structure 2 is its removability. By providing the mortise and tenon structure 2 to connect the shaft, the components can be easily disassembled and reassembled without damaging the overall structure, allowing operators to easily maintain and replace the bearings, thereby reducing maintenance costs and workload.

[0051] At the same time, another key part of this embodiment is the setting of the limit member 3. The limit member 3 is detachably connected to the side of the bearing body away from its shoulder. At the same time, when the limit member 3 is connected to the bearing body, the limit member 3 at least partially protrudes radially from the bearing body, providing additional support and fixation. To a certain extent, it can work together with the bearing body to form a double-sided shoulder structure of the bearing, significantly enhancing the axial stability and load-bearing capacity of the bearing.

[0052] As you can understand, in this embodiment, the addition of the stopper 3 provides effective support on both sides of the bearing body. This design leverages the convenience of a detachable connection, allowing the stopper 3 to be quickly installed or removed as needed without having to replace the entire bearing system. Furthermore, by cooperating with the shoulder on the bearing body, the resulting structure, similar to a double-sided shoulder, enhances the bearing's axial positioning capability and ensures the stability of the main shaft 4 during operation.

[0053] In addition, in this embodiment, the specific form of the shoulder on the bearing body is not limited. The shoulder may be a continuous ring or a discontinuous (intermittent) ring to adapt to different application requirements and installation conditions. For the continuous annular shoulder, it can provide uniform support and positioning, which is suitable for application scenarios that require uniform load distribution. For the discontinuous annular shoulder, it can provide support while reducing weight and improving heat dissipation.

[0054] At the same time, the shoulder can be set on both the first bearing part 11 and the second bearing part 12, or it can be set on only one of the bearing parts. The position of the shoulder needs to be optimized according to the specific load distribution and support requirements to ensure the stability and load-bearing capacity of the bearing assembly.

[0055] Furthermore, the outer contour of the bearing body is circular, a common design in bearing technology and not discussed in detail here. This design provides uniform load distribution, reduces localized stress concentration, and thus extends the bearing's service life. The circular outer contour also helps maintain bearing stability during high-speed rotation, reducing vibration and noise. Furthermore, at least one through-slot 13 is provided on the peripheral wall of the bearing body. This design reduces the overall weight of the bearing body, thereby contributing to the lightweighting of the overall structure or device.

[0056] In one embodiment, the bearing body includes a shoulder portion 111 and a second shoulder portion 121. The first shoulder portion 111 is provided on the first bearing body 11, while the second shoulder portion 121 is provided on the second bearing body 12. These two shoulder portions are located on the same side of the bearing body, forming a single-sided shoulder on one edge of the bearing body. Together with the stopper 3, this creates the double-sided shoulder structure described above. In this embodiment, the shoulder portions are provided on both bearing bodies, which more evenly distributes the axial load, reduces damage caused by local overload, and extends the bearing's service life.

[0057] Based on the above embodiment, the first bearing body 11 and the second bearing body 12 are both designed with a semi-annular profile, so that each shaft body has two butt joints, that is, the first bearing body 11 has two first butt joints 110, and the second bearing body 12 has two second butt joints 120. Each first butt joint 110 corresponds to a second butt joint 120, ensuring precise butt joint between the shaft bodies.

[0058] Each first butt joint end 110 and each second butt joint end 120 is provided with a corresponding mortise and tenon structure 2, allowing them to be plugged and fixed, improving the structural stability and fitting precision of the bearing body. This design not only improves the rotational precision and load-bearing capacity of the bearing, but also facilitates the installation and maintenance process of the bearing, reducing maintenance costs.

[0059] Please refer to the instruction manual Figure 3 The end face extension direction of the first butt end 110 is perpendicular to the radial direction of the bearing body. Correspondingly, the end face extension direction of each second butt end 120 of the second bearing split 12 is consistent with the corresponding first butt end 110. It can also be understood that the angular deviation between the end face and the axial cross section is small, so that the first bearing split 11 and the second bearing split 12 are directly matched in the radial direction, making the connection between the shaft bodies more stable.

[0060] In other embodiments, the end surface of the butt joint is designed as an inclined surface, rather than a traditional vertical surface. This allows for a certain range of axial movement, enabling smooth installation and a tight fit of the bearing even with dimensional errors in the spindle 4. Furthermore, the adaptability of the inclined end surface simplifies and expedites the installation process, reducing the need for precision.

[0061] Furthermore, Figure 3 and Figure 5 As shown, the mortise and tenon structure 2 includes a raised portion 21 and a recessed portion 20. In general, the mortise and tenon structure 2 has two configurations. In the first embodiment, as shown in FIG. Figure 3 As shown, each first butt joint end 110 is provided with a protrusion 21 , and each corresponding second butt joint end 120 is provided with a recess 20 , so that the protrusion 21 can be inserted into the recess 20 for fixation.

[0062] The second embodiment is an alternating arrangement (not shown in the drawings), wherein a protrusion 21 is provided at one first docking end 110, and a recess 20 is provided at a corresponding second docking end 120, while the other first docking end 110 is provided with a recess 20, and the corresponding other second docking end 120 is provided with a protrusion 21, so that the two shafts are fixed and connected in two directions through the mutual engagement of the protrusion 21 and the recess 20.

[0063] In addition, although not shown in the accompanying drawings, it can be understood that when the settings of the first bearing split 11 and the second bearing split 12 are symmetrical, and the cross-sectional shape of the main shaft 4 is also a symmetrical figure, the second alternating setting method is used to connect the first bearing split 11 and the second bearing split 12, which can effectively improve the flexibility and versatility of the docking ends of the two shafts when connected.

[0064] Specifically, during production, the two shafts can be manufactured to the same standard, with one end having a raised portion 21 and the other end having a recessed portion 20. This reduces manufacturing costs and simplifies inventory management. During assembly, simply aligning the corresponding raised portion 21 with the recessed portion 20 creates a secure connection, reducing the number of components involved and minimizing assembly errors caused by mismatched components.

[0065] In the form shown in the accompanying drawings, the first bearing body 11 and the second bearing body 12 are asymmetric in form to match the contour of the main shaft 4, so that each shaft body can more accurately match the contour of the main shaft 4 to achieve a tighter fit, thereby improving the overall stability and load-bearing capacity of the bearing structure.

[0066] As can be seen from the above, the design of the raised portion 21 and recessed portion 20 of the mortise and tenon structure 2 is based on the principle of mechanical interlocking, wherein the raised portion 21 inserts into the corresponding recessed portion 20 to form a fixed connection. The cross-sectional profiles of the raised portion 21 and the recessed portion 20 are matched, ensuring the stability and reliability of the connection. Different cross-sectional profile designs can provide different levels of fit and load-bearing capacity.

[0067] Specifically, the cross-sectional profile of the protrusion 21 can be adjusted according to actual production conditions and requirements.

[0068] Among them, Figure 5 As shown, when the cross-sectional profile of the protrusion 21 is rectangular, the geometric characteristics of the rectangle provide a uniform contact surface in the axial direction, so that the load can be evenly distributed. In addition, the cross-sectional profile of the rectangular protrusion 21 is composed of straight lines, which is easy to manufacture and accurately control the size, thereby ensuring a close fit with the recessed portion 20.

[0069] And as Figure 3 and Figure 6 As shown, in another design of the protrusion 21, the protrusion 21 further includes a clamping portion 212 and a connecting portion 211 arranged at an angle, and the recessed portion 20 further includes a main groove body 201 and a side groove body 202 connected to the main groove body 201. The main groove body 201 is used for the entry of the clamping portion 212, and the side groove body 202 is engaged with the clamping portion 212 to ensure the stability of the connection and provide a limiting effect to prevent falling off.

[0070] In the accompanying drawings, the profile of the protrusion 21 is similar to an L-shape, because the angle between the clamping portion 212 and the connecting portion 211 is a right angle. In fact, in other cases, the angle setting between the clamping portion 212 and the connecting portion 211 can be adjusted as needed to adapt to different application scenarios and load conditions.

[0071] In one embodiment, the limit member 3 is perpendicular to the axial direction of the bearing body and covers the connection between the first bearing body 11 and the second bearing body 12, so that the limit member 3 can effectively protect and strengthen the connection between the two shaft bodies, and prevent structural failure caused by potential weaknesses in the connection. At the same time, the limit member 3 covers the connection, which can prevent the connection part of the shaft body from being subjected to direct mechanical impact or severe wear during use.

[0072] On the other hand, the stopper 3 also acts as a reinforcing rib. When connected to the bearing body, it can enhance the rigidity and stability of the bearing body to a certain extent. In some embodiments, the shape and size of the stopper 3 can be adjusted to accommodate different load conditions or space constraints. In addition, different materials or surface treatment techniques can be used to improve the wear resistance and corrosion resistance of the stopper 3.

[0073] Among them, the limiter 3 can be connected to the first bearing split 11 alone, or to the second bearing split 12 alone, or to both bearing splits at the same time. The specific connection method can be selected according to the actual installation conditions and support requirements.

[0074] Furthermore, the design of the stopper 3 takes into account the convenience of installation. The inner end surface of the stopper 3 does not completely surround the outer circumference of the main shaft 4, but is configured as an open structure. During installation, the stopper 3 can be connected to the outer circumference of the main shaft 4 through the open side, thereby simplifying the installation process and reducing installation time and labor intensity.

[0075] As shown in the figure, the limit member 3 is similar to a semi-ring and is connected to the first bearing split 11 and the second bearing split 12 respectively. While ensuring that the bearing assembly can provide necessary support and positioning, it also combines the above-mentioned convenience of installation, significantly improving the installation efficiency and operational reliability of the bearing assembly.

[0076] In one embodiment, the limit member 3 includes two baffles, namely a first baffle 31 and a second baffle 32, which are stacked on each other to form an integral limit structure. At the same time, through the stacking of the first baffle 31 and the second baffle 32, the limit member 3 can transfer the load more effectively, ensure the tightness of the structure, and also improve the rigidity and stability of the bearing assembly.

[0077] More specifically, the stopper 3 comprises two baffles made of different materials to achieve specific functional and performance requirements. The first baffle 31 is made of metal, while the second baffle 32 is made of plastic. When in use, the second baffle 32 is located between the first baffle 31 and the bearing body, allowing the stopper 3 to fully utilize the high strength of metal and the wear resistance of plastic.

[0078] The metal first baffle 31 provides the high strength and rigidity required by the bearing, ensuring its stability and durability under heavy loads. The plastic second baffle 32, due to its wear resistance, reduces the friction coefficient during operation, thereby reducing wear and increasing the bearing's service life. This combination of plastic and metal baffle design improves the bearing's adaptability to various operating conditions, extends the bearing's maintenance cycle, and reduces long-term operating costs.

[0079] Furthermore, the first baffle 31, the second baffle 32, and the bearing body are connected by a connector that axially penetrates the entire bearing structure, ensuring a tight fit and overall stability between the various components. Alternatively, the bearing body, the first baffle 31, and the second baffle 32 can be penetrated and fixed by long bolts, which can ensure a tight fit and coaxiality between the various components. Alternatively, a nut can be embedded on the side of the bearing body without a shoulder, and then fixed to the first baffle 31 and the second baffle 32 with short screws. This connection method simplifies the installation process and, due to the shorter screws, reduces the installation space required.

[0080] Referring to the drawings in the specification, the first baffle 31, the second baffle 32 and the first bearing split 11 are connected by a first connecting member 61, and the first baffle 31, the second baffle 32 and the second bearing split 12 are connected by a second connecting member 62. The first connecting member 61 and the second connecting member 62 are both in the form of long bolts in this embodiment, but it is obvious that the connection between them is not limited to bolt connection, and they may also be connected in the form of pins, snaps, specific fixing structures, etc.

[0081] In one embodiment, Figure 1 As shown, the first baffle 31 adopts a split design and consists of two split baffles 311 symmetrically arranged along the central axis of the first baffle 31. In addition, the second baffle 32 and each split baffle 311 are provided with connecting holes 60, which are adapted to connect the connecting members 61 to achieve a fixed connection between the two baffles and the bearing body.

[0082] It should be noted that the positions of some connecting holes 60 correspond to the first bearing part 11, while the positions of the remaining connecting holes 60 correspond to the second bearing part 12. The first bearing part 11 and the second bearing part 12 are fixed at the same time by the connecting piece 61, so that the two shafts are tightened and fixed in place, reducing the gap between them, and then reducing the gap between the bearing and the main shaft 4, so as to reduce the vibration and noise of the bearing during operation, improve the rotation accuracy and life of the bearing, and improve the rigidity and stability of the overall structure.

[0083] In addition, the second baffle 32 is made in an integrally formed manner, thereby simplifying the production process, avoiding waste of raw materials, and also ensuring the integrity and consistency of the plastic second baffle 32. However, in other embodiments, the second baffle 32 can also be similar to the first baffle 31 and adopt a split design.

[0084] In one embodiment, according to another aspect of the present application, the present application further provides a photovoltaic tracking bracket, comprising a plurality of columns, a bearing seat 5, a main shaft 4 and the bearing assembly described above.

[0085] The main shaft 4 is installed in the installation space of the bearing body, the bearing seat 5 is installed on the top of each column and is designed with an accommodating space. The bearing body of the bearing assembly is installed in the accommodating space of the bearing seat 5, and the shoulder and limit member 3 cooperate with and abut the two ends of the bearing seat 5.

[0086] Specifically, based on the above embodiment, the bearing assembly includes a first bearing split 11, a second bearing split 12 and a limit member 3. When the bearing assembly and the main shaft 4 and the bearing seat 5 are assembled, the first bearing split 11 and the second bearing split 12 are installed to the outer periphery of the main shaft 4, establishing the initial fit between the bearing body and the main shaft 4. Subsequently, the bearing seat 5 is mounted on the bearing body from the side where the shoulder is not set on the bearing body. At this time, preliminary axial positioning is provided by the first shoulder portion 111 and the second shoulder portion 121. Finally, the limit member 3 is installed and connected and fixed to the bearing body through the connecting member 61 to complete the construction of the double-sided shoulder structure. Of course, according to the on-site construction situation and conditions, you can also choose to first pass the main shaft 4 through the bearing seat 5, and fix the first bearing split 11 and the second bearing split 12 from the upper side and lower side of the main shaft 4 (the left side and the right side are the same). The limiter 3 is installed from the other side of the bearing seat 5 and cooperates with the corresponding shoulder part of the bearing body to form a stable double-sided shoulder structure, ensuring the correct positioning of the bearing body in the radial direction and effectively limiting the axial sliding of the bearing body, thereby enhancing the structural stability of the entire photovoltaic tracking bracket and reducing the displacement and wear caused by wind or mechanical vibration. At the same time, the tracking accuracy of the photovoltaic tracking bracket can also be improved accordingly.

[0087] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
