[0002] A photovoltaic tracker is a photovoltaic support system that can automatically track the position of the sun. It has the advantage of good tracking performance and is widely used in the field of photovoltaic power generation.

[0003] The main shaft is an important component of the photovoltaic tracker. The main shaft generally includes several shafts connected by clamps, which can easily cause torsion and bending stresses to act on the entire main shaft. When the main shaft rotates, the running resistance of the entire main shaft acts on the bearings, which can easily cause damage to the bearings. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a bearing and a photovoltaic tracker, which are not prone to damage.

[0005] In order to solve the above problems, the technical solution provided by the utility model is:

[0006] A bearing, comprising:

[0007] first shell;

[0008] A first shaft sleeve rotatably sleeved in the first housing;

[0009] A first base, one end of which is circumferentially fixedly sleeved in the first shaft sleeve;

[0010] a second housing detachably connected to the first housing;

[0011] A second shaft sleeve rotatably sleeved in the second housing;

[0012] A second base, one end of the second base is circumferentially fixedly sleeved in the second shaft sleeve.

[0013] Optionally, the first base and the second base have the same structure, and both include:

[0014] a first non-rotating portion;

[0015] a second non-rotating portion connected to the first non-rotating portion;

[0016] The first non-rotating portion of the first base is circumferentially fixedly sleeved in the first shaft sleeve, and the first non-rotating portion of the second base is circumferentially fixedly sleeved in the second shaft sleeve.

[0017] Optionally, the first base and the second base have the same structure and both include a first limiting ring connected to one end of the first non-rotating portion away from the second non-rotating portion, the first limiting ring of the first base is in contact with the first sleeve, and the first limiting ring of the second base is in contact with the second sleeve.

[0018] Optionally, a cross-sectional area of ​​the first non-rotating portion is greater than a cross-sectional area of ​​the second non-rotating portion.

[0019] Optionally, it also includes a second limiting ring located inside the first shell and the second shell, one end of the second limiting ring contacts the first sleeve, and the other end of the second limiting ring contacts the second sleeve.

[0020] Optionally, also include:

[0021] a first flange connected to the first housing;

[0022] a second flange connected to the second housing;

[0023] Wherein, the first flange edge and the second flange edge are detachably connected.

[0024] Optionally, also include:

[0025] a first fixing plate connected to the first housing;

[0037] Example 1

[0038] Combined with Figure 1-3 , this embodiment provides a bearing, comprising:

[0039] A first housing 11;

[0040] A first shaft sleeve 12 rotatably sleeved in the first housing 11;

[0041] A first base 13, one end of which is circumferentially fixedly sleeved in the first shaft sleeve 12;

[0042] A second housing 21 detachably connected to the first housing 11;

[0043] A second shaft sleeve 22 rotatably sleeved in the second housing 21;

[0044] The second base 23 has one end which is circumferentially fixedly sleeved in the second shaft sleeve 22 .

[0045] Specifically, the other end of the first base 13 is used to connect with the shaft body 5 of the main shaft, and the other end of the second base 23 is used to connect with the adjacent shaft body 5 of the main shaft. Since the first base 13 rotates around the first shell 11 through the first sleeve 12, and the second base 23 rotates around the second shell 21 through the second sleeve 22, the first base 13 and the second base 23 rotate independently, and then the two adjacent shaft bodies 5 of the main shaft rotate independently, which will not cause twisting and bending stresses to act on the entire main shaft. When the main shaft rotates, the running resistance of the entire main shaft will not act entirely on the bearing, so that the bearing is not easily damaged. In order to facilitate fixing the shaft body 5 of the main shaft, a first fixing hole 131 can be set on the first base 13, and a second fixing hole 231 can be set on the second base 23; in order to ensure that the shaft body 5 of the main shaft can work normally when it deviates from the center line, a large fillet is set at the connection between the first shell 11 and the first sleeve 12, so that the first shell 11 and the first sleeve 12 can achieve universal rotation. At the same time, a large fillet is also set at the connection between the second shell 21 and the second sleeve 22, so that the second shell 21 and the second sleeve 22 can achieve universal rotation. Among them, the material of the first sleeve 12 and the second sleeve 22 can be non-metallic materials such as PP (polypropylene) and PC (polycarbonate).

[0046] Further, such as Figure 1 The first base 13 and the second base 23 have the same structure, and both include:

[0047] A first non-rotating portion 31;

[0048] A second non-rotating portion 32 connected to the first non-rotating portion 31;

[0049] The first non-rotating portion 31 of the first base 13 is circumferentially fixedly sleeved in the first shaft sleeve 12 , and the first non-rotating portion 31 of the second base 23 is circumferentially fixedly sleeved in the second shaft sleeve 22 .

[0050] Specifically, the first non-rotating portion 31 of the first base 13 is used to prevent the first base 13 and the first sleeve 12 from rotating relative to each other, and the first non-rotating portion 31 of the second base 23 is used to prevent the second base 23 and the second sleeve 22 from rotating relative to each other, wherein the cross-sectional shape of the first non-rotating portion 31 may be rectangular, elliptical, etc.; the second non-rotating portion 32 of the first base 13 is used to prevent the first base 13 and the shaft body 5 of the main shaft from rotating relative to each other, and the second non-rotating portion 32 of the second base 23 is used to prevent the second base 23 and the adjacent shaft body 5 of the main shaft from rotating relative to each other, wherein the cross-sectional shape of the second non-rotating portion 32 may be rectangular, elliptical, etc.

[0051] Further, such as Figure 1The first base 13 and the second base 23 have the same structure and both include a first limiting ring 33 connected to one end of the first non-rotating portion 31 away from the second non-rotating portion 32. The first limiting ring 33 of the first base 13 contacts the first sleeve 12, and the first limiting ring 33 of the second base 23 contacts the second sleeve 22.

[0052] Specifically, the first limiting ring 33 of the first base 13 is used to limit the relative axial position of the first base 13 and the first sleeve 12 ; the first limiting ring 33 of the second base 23 is used to limit the relative axial position of the second base 23 and the second sleeve 22 .

[0053] Further, such as Figure 1 , the cross-sectional area of ​​the first non-rotating portion 31 is greater than the cross-sectional area of ​​the second non-rotating portion 32 .

[0054] Specifically, the size of the bearing is relatively large, and the size of the main shaft body 5 is relatively small, so as to ensure that the bearing has a good load-bearing effect on the main shaft body 5.

[0055] Further, such as Figure 1 , and also includes a second limiting ring 4 located in the first shell 11 and the second shell 21 , one end of the second limiting ring 4 contacts the first sleeve 12 , and the other end of the second limiting ring 4 contacts the second sleeve 22 .

[0056] Specifically, the second limiting ring 4 is used to prevent the first sleeve 12 and the second sleeve 22 from approaching each other.

[0057] Further, such as Figure 1-2 , also includes:

[0058] A first flange edge 14 connected to the first housing 11;

[0059] A second flange edge 24 connected to the second housing 21;

[0060] The first flange edge 14 and the second flange edge 24 are detachably connected.

[0061] Specifically, the first flange edge 14 and the second flange edge 24 are both used to cooperate with the fasteners, so as to facilitate the detachable connection between the first shell 11 and the second shell 21.

[0062] Further, such as Figure 1-2 , also includes:

[0063] A first fixing plate 15 connected to the first housing 11;

[0064] A plurality of first waist-shaped holes 151 provided on the first fixing plate 15;

[0065] A second fixing plate 25 connected to the second housing 21;

[0066] A plurality of second waist-shaped holes 251 are disposed on the second fixing plate 25 .

[0067] Specifically, the first fixing plate 15 is used to fix the first shell 11 on the relevant carrier, and the first waist-shaped holes 151 facilitate the adjustment of the fixed position; the second fixing plate 25 is used to fix the second shell 21 on the relevant carrier, and the second waist-shaped holes 251 facilitate the adjustment of the fixed position.

[0068] This embodiment further provides a photovoltaic tracker, including a plurality of bearings of this embodiment, and also including a plurality of shafts 5 , the other end of the first base 13 is connected to the shaft 5 , and the other end of the second base 23 is connected to the adjacent shaft 5 .

[0069] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
