There is room for improvement. Utility Model Content

[0023] The reinforcing block group includes a first clamping block, which is formed on the end surface of the second arm away from the first arm and extends axially along the second bearing body;

[0024] When the first combining portion and the second combining portion are combined, the first clamping block is embedded in the slide groove along the axial direction of the first combining portion, and then is slidably connected with the inner wall of the slide groove around the axis of the first combining portion.

[0025] In a split bearing provided by the present application, the first block and the slide groove are used to increase the connection area between the first joint part and the second joint part, so as to improve the structural strength of the connection of the split bearing, thereby effectively reducing the occurrence of deflection caused by weight damaging the split bearing and extending the service life of the split bearing.

[0029] In some embodiments, the split bearing further includes a locking member, and the locking member is used to lock the locking arm in the locking groove.

[0030] A split bearing provided by the present application is provided with a locking piece to lock the snap-fit ​​arm in the locking groove, which, on the one hand, helps to further enhance the anti-separation capability of the split bearing along the axis of the main shaft and perpendicular to the axis of the main shaft; at the same time, it helps to further increase the connection area between the first bearing split and the second bearing split, further extending the service life of the split bearing, thereby further ensuring the long-term stable operation and overall power generation of the corresponding photovoltaic tracking bracket.

[0031] In some embodiments, the locking member includes a spacer;

[0032] After the buckling arm is fixedly engaged with the locking groove, a movable space is formed between the side of the first arm away from the locking point of the second arm and the narrow slot and the inner wall of the open portion away from the locking point of the second arm and the narrow slot;

[0033] The shape of the cushion block is adapted to the shape of the activity space, and the cushion block can be installed in the activity space to firmly connect the first combining portion and the second combining portion.

[0034] In some embodiments, the width of the cushion block along the axis of the split bearing is equal to the width of the activity space, so as to press the first arm against the inner wall of the open portion close to the engaging point between the second arm and the narrow slot portion;

[0035] The length of the cushion block along the axial direction of the split bearing is equal to the height of the activity space, so that the two ends of the cushion block along the axial direction of the split bearing are respectively pressed against the two end surfaces of the first bearing split and the second bearing split that are close to each other.

[0036] The split bearing provided by the present application uses a cushion block to press against the side wall of the first arm and the corresponding inner wall of the open portion, which helps prevent the first bearing split and the second bearing split from retreating around the main shaft axis during use, thereby increasing the structural stability of the split bearing. At the same time, using the cushion block to press against the two end faces of the first bearing split and the second bearing split that are close to each other helps reduce the relative shaking of the first bearing split and the second bearing split along the axial direction during use, further improving the stability of the split bearing structure.

[0037] By filling a spacer in the gap produced by the relative rotation of the locking groove and the snap-fit ​​arm, a stable connection between the first bearing split and the second bearing split is achieved.

[0041] In some embodiments, the side walls of the first shoulder and the second shoulder facing away from each other are both provided with positioning marks, and the positioning mark on the first shoulder and the positioning mark on the second shoulder are aligned along the axial direction of the first bearing split and / or the second bearing split when the snap arm is fixedly engaged with the positioning groove.

[0042] In the split bearing provided by the present application, when the snap-fit ​​arm and the snap-fit ​​groove are fixedly snapped together during actual assembly, that is, after the assembly of the split bearing is completed, the snap-fit ​​mark on the first shaft shoulder and the snap-fit ​​mark on the second shaft shoulder are aligned along the axial direction. The snap-fit ​​marks are respectively provided at both ends of the split bearing, so that the staff can judge the assembly state of the split bearing, which helps to steadily improve the convenience of use of the split bearing.

[0044] 1. In the present application, an embedding groove group and a reinforcing block group are correspondingly provided at the connection between the first bearing split and the second bearing split.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0057] At present, photovoltaic tracking brackets on the market usually install split plastic bearings to rotate the main shaft at the top of the column to adjust the angle of the photovoltaic module on it. In the related art, the plastic bearings on the photovoltaic tracking bracket need to bear the weight of the main shaft, the photovoltaic module installed on the main shaft, and the torque generated when the main shaft rotates. The pressure generated by the weight will accelerate the damage of the split plastic bearing along its own axis, and it needs to be replaced frequently. As a result, the corresponding photovoltaic tracking bracket often cannot operate normally, affecting the overall power generation, and the enterprise cost is high, which needs to be improved.

[0058] To solve the above technical problems, refer to the accompanying drawings of the specification Figures 1 to 4In one embodiment, a split bearing is provided, comprising a first bearing split 1 and a second bearing split 2, wherein the first bearing split 1 comprises a first annular portion and a first coupling portion 11, and a groove group 3 is provided on the first coupling portion 11; the second bearing split 2 comprises a second annular portion and a second coupling portion 21, and a reinforcement block group 4 is provided on the second coupling portion 21 corresponding to the groove group 3; during actual assembly, the first annular portion and the second annular portion are kept coaxial, and the first coupling portion 11 and the second coupling portion 21 are arranged opposite to each other, even if the first bearing split 1 and the second bearing split 2 are arranged coaxially, when the first coupling portion 11 is at least partially embedded in the second coupling portion 21, the reinforcement block group 4 is synchronously embedded in the corresponding groove group 3, so that the first bearing split 1 and the second bearing split 2 are integrated into one, and firmly connected to form an integral split bearing.

[0059] In this way, the connection area between the first bearing split 1 and the second bearing split 2 is increased by means of the snap-fitting of the embedded groove group 3 and the reinforcing block group 4, the connection of the split bearing is strengthened, the influence of the pressure on the main shaft on the structural strength of the split bearing is reduced, the probability of damage to the split bearing along the main shaft axis is reduced, its anti-separation ability along the main shaft axis and perpendicular to the main shaft axis is improved, its service life is extended, and the number of replacements of the split bearing during use is reduced, which effectively guarantees the long-term stable operation of the corresponding photovoltaic tracking bracket, and thus guarantees the overall power generation. At the same time, since the embedded groove group 3 and the reinforcing block group 4 have a simple molding process and convenient setting, the production and use convenience of the split bearing is effectively guaranteed, and the relevant cost investment of the enterprise is effectively reduced, promoting energy conservation and cost reduction.

[0060] In one embodiment, based on the above embodiment, specifically, referring to Figures 1 to 4 In order to achieve efficient connection between the first bearing split 1 and the second bearing split 2, in this embodiment of the present application, a locking groove 111 is provided at one end of the first combining portion 11 axially away from the first annular portion, and a snap-fit ​​arm 211 is provided at one end of the second combining portion 21 axially away from the second annular portion. In actual application, the first combining portion 11 and the second combining portion 21 are snap-fitted with the locking groove 111 and the snap-fit ​​arm 211 to achieve connection between the first bearing split 1 and the second bearing split 2, that is, to achieve assembly of the split bearing.

[0061] At the same time, in order to ensure the assembly stability of the split bearing, in this embodiment of the present application, at least two groups of corresponding locking grooves 111 and locking arms 211 are provided, and at least two groups of matching locking grooves 111 and locking arms 211 are distributed in a circular array around the axis of the first bearing split 1 and / or the second bearing split 2.

[0062] Specifically, refer to Figure 3The positioning groove 111 includes an open portion 1111 and a narrow groove portion 1112, which are sequentially arranged along the axial direction of the first coupling portion 11, the open portion 1111 is connected to the narrow groove portion 1112, and the open portion 1111 is formed on a side of the narrow groove portion 1112 away from the first annular portion. Figure 2 The snap-fit ​​arm 211 includes a first arm 2111 and a second arm 2112, the first arm 2111 and the second arm 2112 are integrally connected along the axial direction of the second joint portion 21, and the first arm 2111 extends along the axial direction of the second joint portion 21, the second arm 2112 extends around the axis of the second joint portion 21, and the second arm 2112 is located on the side of the first arm 2111 away from the second annular portion. At the same time, since the first bearing sub-body 1 and the second bearing sub-body 2 are assembled along the axial direction, in this embodiment of the present application, the length of the second arm 2112 around the axis of the second joint portion 21 is less than the length of the open portion 1111 around the axis of the first joint portion 11; and, in order to achieve the locking of the first bearing sub-body 1 and the second bearing sub-body 2 along the axial direction, the length of the open portion 1111 around the axis of the first joint portion 11 is less than the length of the narrow groove portion 1112 around the axis of the first joint portion 11. The shape of the snap-fit ​​arm 211 is adapted to the positioning groove 111.

[0063] When the first bearing sub-body 1 and the second bearing sub-body 2 are assembled, one end of the first joint part 11 formed on the first bearing sub-body 1 or one end of the second joint part 21 formed on the second bearing sub-body 2 coaxially extends into one end of the inner hole of the bearing seat, and then the first joint part 11 and the second joint part 21 are kept opposite to each other, and one end of the second joint part 21 formed on the second bearing sub-body 2 or one end of the first joint part 11 formed on the first bearing sub-body 1 extends into the inner hole of the bearing seat from the other end of the bearing seat, and the positioning groove 111 corresponds to the buckling arm 211 one by one. The snap-fit ​​arms 211 are all axially embedded in the corresponding snap-fit ​​grooves 111 along the first bearing split body 1 and / or the second bearing split body 2. Specifically, any second arm 2112 extends from the corresponding open portion 1111 into the corresponding narrow slot portion 1112 along the axial direction of the first joint portion 11, and then slides relative to the side wall of the narrow slot portion 1112 around the axis of the first joint portion 11 until the side of the first arm 2111 abuts against the corresponding side wall of the open portion 1111, thereby combining the first bearing split body 1 and the second bearing split body 2 into one body to assemble the split bearing. The connection structure of the split bearing is simple, and the two split bodies can be stably connected by the method of "axial insertion-rotation around the axis", which effectively ensures its assembly efficiency and the construction efficiency of the corresponding photovoltaic tracking bracket; at the same time, the overall structure is simple, the production difficulty is low, and it is easy to use, which effectively reduces the cost of the enterprise.

[0064] In this embodiment of the present application, refer to Figure 2 and Figure 3The embedding groove group 3 is arranged corresponding to the locking groove 111, and the embedding groove group 3 is opened on the side wall of the locking groove 111; the reinforcement block group 4 is arranged corresponding to the buckling arm 211, and the reinforcement block group 4 is formed on the side wall of the buckling arm 211.

[0065] Specifically, in this embodiment of the present application, refer to Figure 3 and Figure 4 The embedding groove group 3 includes a sliding groove 31 and a fixing groove 32, wherein the sliding groove 31 is opened on the bottom wall of the open portion 1111, and its depth extends toward the end of the first connecting portion 11 away from the second connecting portion 21 along a direction perpendicular to the bottom wall of the open portion 1111, and its length extends into the narrow groove portion 1112 around the axis of the first connecting portion 11; the fixing groove 32 is opened on the side wall of the open portion 1111, and its depth extends around the axis of the first connecting portion 11.

[0066] Reference Figure 2 and Figure 4 The reinforcement block group 4 specifically includes a first block 41 and a second block 42. The first block 41 is formed on the end surface of the second arm 2112 away from the first arm 2111, and its length extends along the axial direction of the second joint portion 21; the second block 42 is formed on the side surface of the first arm 2111, and its length also extends around the axis of the second joint portion 21.

[0067] In actual application, when the split bearing is assembled, the locking arm 211 is axially embedded in the corresponding locking groove 111 along the first joint part 11, and at the same time, the first clamping block 41 is axially embedded in the corresponding sliding groove 31 along the first joint part 11; then the second arm 2112 slides relative to the side wall of the narrow groove part 1112 around the axis of the first joint part 11, and the second clamping block 42 is synchronously embedded in the corresponding fixed groove 32, and slides relative to the inner wall of the fixed groove 32 around the axis of the first joint part 11, until the corresponding side surface of the first arm 2111 abuts against the corresponding side wall of the open part 1111, thereby combining the first bearing split 1 and the second bearing split 2 into one.

[0068] Through the unique groove structure, the connection area between the first bearing split 1 and the second bearing split 2 is effectively increased, thereby improving the split bearing's ability to resist pressure and torque along the main shaft and perpendicular to the main shaft, improving the first bearing split 1 and the second bearing split 2's anti-separation ability, and extending the service life of the split bearing, thereby ensuring the long-term stable operation of the corresponding photovoltaic tracking bracket and the overall power generation.

[0069] Reference Figures 1 to 4In this embodiment of the present application, the positioning groove 111 and the snap-fit ​​arm 211 are both L-shaped structures, so during assembly, the first bearing body 1 and the second bearing body 2 can only rotate in one direction (i.e., the extension direction of the second arm 2112) around the main shaft axis. In the implementation of the present application, the positioning groove 111 and the snap-fit ​​arm 211 can also be set as a T-shaped structure. In this case, during the assembly process, the first bearing body 1 can rotate in two directions around the main shaft axis relative to the second bearing body 2, thereby improving the ease of use of the split bearing. Of course, in the implementation of the present application, the specific shapes of the positioning groove 111 and the snap-fit ​​arm 211 should not be used as a limitation on the scope of protection of the present application; this embodiment of the present application is only described by taking the positioning groove 111 and the snap-fit ​​arm 211 as an example of an L-shaped structure.

[0070] Furthermore, in order to ensure a stable connection between the first bearing body 1 and the second bearing body 2 during use, the split bearing further includes a locking member for locking the snap-fit ​​arm 211 in the locking groove 111 .

[0071] Reference Figure 1 and Figure 4 After the snap-fit ​​arm 211 is engaged with the locking groove 111, a movable space 5 is formed between the side of the first arm 2111 away from the engaging point between the second arm 2112 and the slot portion 1112, the side of the open portion 1111 away from the engaging point between the second arm 2112 and the slot portion 1112, and the two end walls where the first joint portion 11 and the second joint portion 21 are close to each other. Therefore, in this embodiment of the present application, the locking member can be set as a cushion block, and the shape of the cushion block is adapted to the shape of the movable space 5.

[0072] Furthermore, in this embodiment of the present application, the shape of the cushion block is adapted to the shape of the activity space 5, which means that the width of the cushion block along the axis of the split bearing is equal to the width of the activity space, and the length of the cushion block along the axis of the split bearing is equal to the height of the activity space. In specific applications, after the cushion block fills the activity space 5, its two ends around the axis of the first joint 11 and / or the second joint 21 respectively abut against the side of the first arm 2111 away from the second arm 2112 and the slot 1112, and the side of the open portion 1111 away from the second arm 2112 and the slot 1112, so as to prevent the first bearing split 1 and the second bearing split 2 from retreating around the main shaft axis during use; at the same time, the two ends of the cushion block along the axial direction of the first joint 11 and / or the second joint 21 respectively abut against the end faces of the first joint 11 and the second joint 21 that are close to each other, so as to reduce the relative shaking of the first bearing split 1 and the second bearing split 2 along the axial direction during use; thereby, the stability of the overall structure of the split bearing is improved.

[0073] Reference Figures 1 to 4In this embodiment of the present application, the activity space 5 is generally formed as a rectangular space, and correspondingly, the cushion block is set as a generally rectangular block structure. Of course, the cushion block can also be a cross-shaped, H-shaped or other block structure, as long as the width of the cushion block along the axis of the split bearing is equal to the width of the activity space, and the length of the cushion block along the axial direction of the split bearing is equal to the height of the activity space.
