[0030] Example 1
[0031] Combined with Figure 1-3 , this embodiment provides a low-cost bearing, including:
[0032] U-bolt 1;
[0033] A bearing seat 2 located within the U-bolt 1;
[0034] A shaft sleeve 3 rotatably connected to the bearing seat 2;
[0035] A fixing plate 4 detachably connected to the U-bolt 1, one side of the fixing plate 4 being in contact with the bearing seat 2;
[0036] The nut is threadedly connected to the U-bolt 1 , and the nut is in contact with the other side of the fixing plate 4 .
[0037] Specifically, the nut cooperates with the fixing plate 4 to fix the bearing seat 2 in the U-bolt 1, wherein there are two nuts, which are respectively threadedly connected to the two screws of the U-bolt 1, and the fixing plate 4 is also used to fix the low-cost bearing on the relevant carrier; the bearing seat 2 is used to carry the sleeve 3, so that the sleeve 3 can rotate around the bearing seat 2; the sleeve 3 is used to carry the main shaft of the photovoltaic tracker, so that the main shaft of the photovoltaic tracker can rotate around the bearing seat 2; in summary, the low-cost bearing is formed by combining conventional U-bolts 1, nuts, bearing seats 2 and sleeves 3, so that the cost of the low-cost bearing is low.
[0038] Further, such as Figure 1 The shaft sleeve 3 includes a first set 31 and a second set 32 which are both rotatably connected to the bearing seat 2. The first set 31 is provided with a first square hole 311, and the second set 32 is provided with a second square hole 321. The first square hole 311 and the second square hole 321 are connected.
[0039] Specifically, the first square hole 311 and the second square hole 321 are used to jointly accommodate the main shaft of the photovoltaic tracker, and enable the main shaft of the photovoltaic tracker, the first set 31 and the second set 32 to rotate synchronously.
[0040] Further, such as Figure 1 , also includes:
[0041] Two first limiting pieces 312 respectively connected to the two sides of the first set 31, and the two first limiting pieces 312 are respectively located on the two sides of the bearing seat 2;
[0042] The two second limiting plates 322 are respectively connected to the two sides of the second set 32 , and the two second limiting plates 322 are respectively located on the two sides of the bearing seat 2 .
[0043] Specifically, the two first limiting plates 312 are used to prevent the first set 31 and the bearing seat 2 from being separated from each other in the axial direction; the two second limiting plates 322 are used to prevent the second set 32 and the bearing seat 2 from being separated from each other in the axial direction.
[0044] Further, such as Figure 1 , further comprising a cavity 33 formed between the first set 31 and the second set 32.
[0045] Specifically, the cavity 33 is equivalent to the first kit 31 and the second kit 32 not being a complete cylinder, so that the first kit 31 and the second kit 32 can be disassembled and assembled with the bearing seat 2 in the radial direction, thereby facilitating the replacement of the first kit 31 with the first square hole 311 of different sizes and the second kit 32 with the second square hole 321 of different sizes, thereby facilitating the adaptation of the main shaft of photovoltaic trackers of different sizes, thereby reducing the stocking cost and further reducing the cost of the low-cost bearing.
[0046] Further, such as Figure 1 The first set 31 and the second set 32 are arranged axially symmetrically with respect to the cavity 33 .
[0047] Specifically, the axisymmetric setting facilitates the force symmetry of the main axis of the photovoltaic tracker to be good.
[0048] Further, such as Figure 1 , and also includes a first limiting rod and a second limiting rod both connected to the bearing seat 2, and the first limiting rod and the second limiting rod are respectively located on both sides of the U-bolt 1.
[0049] Specifically, the first limit rod and the second limit rod are used to prevent the bearing seat 2 and the U-bolt 1 from separating from each other along the axial direction. The first limit rod and the second limit rod can both be conventional fasteners such as countersunk screws and semi-countersunk screws, which further reduces the cost of the low-cost bearing.
[0050] Further, such as Figure 1 , and also includes a first limiting screw hole 21 and a second limiting screw hole 22, both of which are arranged on the bearing seat 2. The first limiting screw hole 21 and the second limiting screw hole 22 are respectively located on both sides of the U-shaped bolt 1, the first limiting rod and the first limiting screw hole 21 are threadedly connected, and the second limiting rod and the second limiting screw hole 22 are threadedly connected.
[0051] Further, such as Figure 1 , and also includes a plurality of waist-shaped holes 41 arranged on the fixing plate 4.
[0052] Specifically, the waist-shaped hole 41 facilitates adjustment of the specific fixing position of the low-cost bearing according to needs.
[0053] Further, such as Figure 1 , and also includes a chamfer 23 arranged on the bearing seat 2.
[0054] Specifically, the chamfer 23 is convenient for saving the material of the bearing seat 2 and preventing the bearing seat 2 and the U-bolt 1 from interfering with each other.
[0055] This embodiment also provides a photovoltaic tracker, including a low-cost bearing as in this embodiment.
[0056] 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.
