[0036] Example 1

[0037] Combined with Figure 1-3 , this embodiment provides a rolling bearing, comprising:

[0038] Bearing seat 3;

[0039] A number of rollers 4;

[0040] A first end plate 1 fixedly connected to one end of a plurality of rollers 4;

[0041] A second end plate 2 fixedly connected to the other ends of the plurality of rollers 4;

[0042] Corresponding to the plurality of rollers 5 rotatably sleeved outside the plurality of roller shafts 4, the plurality of rollers 5 are rotatably sleeved inside the bearing seat 3;

[0043] The first end plate 1 and the second end plate 2 are both used for circumferentially fixed connection with the main shaft.

[0044] Specifically, a plurality of rollers 4 are used for fixedly connecting the first end plate 1 and the second end plate 2, and a plurality of rollers 4 are also used for correspondingly rotating and bearing a plurality of rollers 5. Since the plurality of rollers 5 are rotatably sleeved in the bearing seat 3, it is equivalent to that the plurality of rollers 4, the plurality of rollers 5, the first end plate 1 and the second end plate 2 are all rotatably sleeved in the bearing seat 3. Since the first end plate 1 and the second end plate 2 are both used for circumferentially fixed connection with the main shaft, it is convenient for the main shaft and the first end plate 1 and the second end plate 2 to rotate synchronously, so that the main shaft is rotatably sleeved in the bearing seat 3, wherein the plurality of rollers 5 and the bearing seat 3 realize multi-point line contact friction rather than surface contact friction, so as to prevent the accumulation of sand and dust between the plurality of rollers 5 and the bearing seat 3, thereby preventing the rolling bearing from being damaged.

[0045] Further, such as Figure 3 , the bearing seat 3 comprises:

[0046] The seat body 31, the plurality of rollers 5 are rotatably sleeved in the seat body 31;

[0047] A fixing plate 32 connected to the seat body 31;

[0048] A plurality of fixing holes 321 are provided on the fixing plate 32 .

[0049] Specifically, the seat body 31 is used to carry a number of rollers 5; the fixing plate 32 is used to carry a number of fixing holes 321, and the several fixing holes 321 are all used to accommodate fasteners, and the fasteners are used to indirectly connect the fixing plate 32 to the ground, thereby facilitating the indirect connection of the rolling bearing to the ground.

[0050] Further, such as Figure 3 , the bearing seat 3 also includes:

[0051] A channel 311 is provided in the seat body 31, and a plurality of rollers 4 and a plurality of rollers 5 are rotatably located in the channel 311;

[0052] The discharge hole 33 is provided in the seat body 31 and the fixing plate 32 , and the discharge hole 33 is communicated with the channel 311 .

[0053] Specifically, the channel 311 is used to accommodate a plurality of rollers 4 and a plurality of rollers 5; the discharge hole 33 is used to timely discharge the sand and dust in the channel 311, further preventing the accumulation of sand and dust between the plurality of rollers 5 and the bearing seat 3, thereby facilitating further preventing the rolling bearing from being damaged.

[0054] Further, such as Figure 3, the diameters of the first end plate 1 and the second end plate 2 are both larger than the diameter of the channel 311 .

[0055] Specifically, the diameters of the first end plate 1 and the second end plate 2 are relatively large, which makes it easier to prevent the first end plate 1 and the second end plate 2 from passing through the channel 311 axially, thereby preventing the first end plate 1, the second end plate 2, the plurality of rollers 4 and the plurality of rollers 5 from being separated from the bearing seat 3.

[0056] Further, such as Figure 1 and 3 , also includes:

[0057] A first non-rotating hole 11 provided on the first end plate 1;

[0058] A second non-rotating hole 21 provided on the second end plate 2;

[0059] The first non-rotating hole 11 and the second non-rotating hole 21 are both used for circumferentially fixed connection with the main shaft.

[0060] Specifically, the specific shapes of the first non-rotational hole 11 and the second non-rotational hole 21 can be square, triangle, etc., preferably square.

[0061] Further, such as Figure 1 and 3 , the first non-rotational hole 11 and the second non-rotational hole 21 have the same shape.

[0062] Specifically, the same shape facilitates good force consistency at both ends of the main shaft.

[0063] Further, such as Figure 3 A plurality of rollers 4 are evenly distributed along the circumference of the first end plate 1 and the second end plate 2 , and a plurality of rollers 5 are evenly distributed along the circumference of the first end plate 1 and the second end plate 2 .

[0064] Specifically, the circumferentially uniform distribution facilitates increasing the uniformity of the force inside the rolling bearing.

[0065] Further, such as Figure 2 The first end plate 1 and the second end plate 2 are arranged axially symmetrically about the bearing seat 3.

[0066] Specifically, the axisymmetric arrangement facilitates good force symmetry at both ends of the main axis.

[0067] This embodiment also provides a photovoltaic tracker, including a rolling bearing in this embodiment.

[0068] 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.
