In some embodiments, as shown in fig. 2, 4, 6 and 8, the bearing assembly includes a bearing housing 11, a bearing 12 and a stopper 13.

Illustratively, the bearing housing 11 may have a cylindrical or conical inner bore for mating with the outer race of the bearing 12, and the outer contour of the bearing housing 11 may be square, circular or otherwise shaped to accommodate different mounting requirements.

The material of the bearing housing 11 may include, but is not limited to, cast iron, stainless steel, or aluminum alloy, etc., which is not limited thereto.

For example, in some embodiments, the bearing housing 11 is made of stainless steel.

The bearing 12 may be used to support the spindle 14 of the photovoltaic bracket 10 and allow the spindle 14 to freely rotate on a fixed axis.

The bearing 12 may be made of a metal material or a plastic material, wherein the metal material may include, but is not limited to, high carbon chromium bearing 12 steel, stainless steel, cast iron or aluminum-based alloy, etc., and the plastic material may include, but is not limited to, acetal, polyetheretherketone, polyoxymethylene, polytetrafluoroethylene or phenolic resin, etc.

For example, in some embodiments, the bearing 12 may be made of a plastic material.

To facilitate assembly between the bearing 12 and the bearing housing 11 and the main shaft 14, the bearing 12 may be split circumferentially into two parts, namely a first part 121 and a second part 122, and the first part 121 and the second part 122 are each half of the bearing 12, in other words, the first part 121 and the second part 122 are each generally semi-cylindrical.

The first portion 121 and the second portion 122 may be spliced end to form the circumferentially closed bearing 12, and the first portion 121 and the second portion 122 may be spaced apart to form the bearing 12 in a split structure.

For example, in some embodiments, as shown in fig. 1-8, the first portion 121 and the second portion 122 are spaced apart.

In particular, the first portion 121 and the second portion 122 may be spaced apart in a vertical direction, may be spaced apart in a horizontal direction, and may be spaced apart in other directions, without limitation.

For example, in some embodiments, as shown in fig. 1-8, the first portion 121 and the second portion 122 are spaced apart in a vertical direction.

The shape of the outer contour of the first boss 1211 may be a circular arc shape, a wave shape, a bent shape, or the like, without limitation.

As shown in fig. 1-8, the limiting member 13 penetrates at least one of the first portion 121 and the second portion 122, and the limiting member 13 has a limiting portion 131 protruding from an outer peripheral wall of the bearing 12, wherein the first boss 1211 and the limiting portion 131 protruding from the outer peripheral wall of the first portion 121 are respectively located at two axial sides of the bearing seat 11, and the second boss 1221 and the limiting portion 131 protruding from the outer peripheral wall of the second portion 122 are respectively located at two axial sides of the bearing seat 11.

The limiting member 13 may be an elongated bar member, and in particular, the limiting member 13 may include, but is not limited to, cotter pins, bolts or rivets, etc., without limitation.

For example, in some embodiments, as shown in fig. 1-4, the stop 13 is a cotter pin.

For example, in other embodiments, as shown in fig. 5-8, the stop 13 is a bolt.

The length direction of the stopper 13 may be parallel to the vertical direction, the horizontal direction, or other directions so as not to interfere with the criterion of the arrangement direction of the stopper 13 between the main shaft 14 and the bearing 12.

The manner of opening the first portion 121 and the second portion 122 includes, but is not limited to, mechanical drilling, laser drilling, punching, or spark drilling, among others.

The shape and size of the through holes on the first portion 121 and the second portion 122 may be designed according to the shape and size of the stopper 13, wherein the through holes on the first portion 121 may include, but are not limited to, round holes, square holes, triangular holes, or the like, and the through holes on the second portion 122 may include, but are not limited to, round holes, square holes, triangular holes, or the like.

For example, in some embodiments, the through-holes in the first portion 121 are circular holes and the through-holes in the first portion 121 are circular holes.

In the related art, some bearings are provided with a bearing shield plate on the opposite side of the boss, and the bearing shield plate is fastened with bolts to prevent the bearing from coming out. The scheme has the following defects that on one hand, the bearing baffle plate and corresponding fasteners are required to be added, the number of parts required to be used is excessive, so that the installation cost is increased, on the other hand, when the bearing baffle plate is stopped against the bearing seat to exert the limiting function, all the stress born by the bearing baffle plate is borne by the fasteners, the fasteners are extremely easy to fatigue and lose efficacy after long-term use, and meanwhile, the fasteners themselves have risks of being not fastened in place, so that the service life of the fasteners is too short, and the fasteners are required to be replaced frequently.

It can be understood that, since the first boss 1211 and the limiting portion 131 protruding from the outer peripheral wall of the first portion 121 are respectively located at two sides of the axial direction of the bearing seat 11, and the second boss 1221 and the limiting portion 131 protruding from the outer peripheral wall of the second portion 122 are respectively located at two sides of the axial direction of the bearing seat 11, in this way, the side of the first portion 121 without the first boss 1211 is provided with the limiting member 13 to form the protruding limiting portion 131, and the opposite side of the first boss 1211 combined with the opposite side of the limiting portion 131 protruding from the first portion 121 can realize the limiting of the first portion 121 in the axial direction, and in the same way, the opposite side of the second portion 122 without the second boss 1221 is provided with the limiting member 13 to form the protruding limiting portion 131, and the opposite side of the second boss 1221 combined with the opposite side of the limiting portion 131 protruding from the second portion 122 can realize the limiting of the second portion 122 in the axial direction. In the process of installing the bearing 12, the first part 121 and the second part 122 are only required to be positioned and arranged at the corresponding positions of the bearing seat 11, and then each limiting piece 13 penetrates through the corresponding part, and in the process of disassembling the bearing 12, each limiting piece 13 is only required to be disassembled and taken out from the corresponding penetrating part, and then the first part 121 and the second part 122 are required to be disassembled from the bearing seat 11. In addition, when the limiting part 131 is stressed, due to the assembly mode of penetrating installation of the limiting part 13, the bearing 12 can assist the limiting part 13 to resist the external stress driving the bearing 12 to move, even if the limiting part 13 is slightly bent after long-term use, the limiting effect is not affected, and the limiting part 13 is straightened only by using a corresponding tool during maintenance.

It should be noted that, in the assembled state of the bearing assembly, the limiting portion 131 and the first boss 1211 may abut against the outer surface of the bearing seat 11, or may leave a certain gap for convenient installation, and the left gap should not be too large, so as to prevent the stability of the rotation of the spindle 14 from being affected due to too large axial movement space left for the bearing 12.

According to the bearing assembly provided by the embodiment of the application, through the arrangement of the first boss 1211, the second boss 1221 and the limiting piece 13, the position limitation of the bearing 12 relative to the bearing seat 11 along the axial direction is realized, the risks of looseness, position deviation or falling of the bearing 12 are reduced, so that the stability and reliability of the photovoltaic bracket 10 are improved, the long-term stable operation of a photovoltaic system is further maintained, compared with a common scheme of a baffle of the bearing 12, the number of parts required to be used is reduced, the installation cost is reduced, meanwhile, the installation procedure is simplified, the installation efficiency is improved, meanwhile, the bearing 12 can assist the limiting piece 13 by utilizing the penetrating type assembly mode of the limiting piece 13 so as to resist external stress, the service life of the limiting piece 13 is prolonged, the maintenance frequency of the limiting piece 13 is remarkably reduced, the maintainability of the limiting piece 13 is improved, and secondly, the penetrating type assembly mode enables the limiting piece 13 to be applicable to the bearings 12 with different sizes and shapes, the diversity and the flexibility of the bearing 12 in the type design are increased, and the application range of the bearing assembly is enlarged.

In some embodiments, as shown in fig. 1-2 and 7-8, the stop 13 extends through the first portion 121 and the second portion 122.

The first portion 121 and the second portion 122 are spaced apart and are opposite to each other, and the limiting member 13 penetrates through the first portion 121 and the second portion 122 at the same time, in other words, the through hole in the first portion 121 and the through hole in the second portion 122 are opposite to each other, and when the limiting member 13 is installed, only the through hole in the first portion 121 and the through hole in the second portion 122 need to pass through in sequence, so that the limiting member 13 realizes the limiting effect and also realizes the indirect connection between the first portion 121 and the second portion 122.

According to the bearing assembly provided by the embodiment of the application, through the structural design that the limiting piece 13 penetrates through the first part 121 and the second part 122, the limiting piece 13 realizes the axial limiting function, and simultaneously, the first part 121 and the second part 122 are combined to form a firmer integral structure, so that radial deflection of the bearing 12 in the rotating process is effectively prevented, and the risk of deformation or damage of the bearing 12 due to uneven stress or vibration in the long-term use process is reduced.

In some embodiments, as shown in fig. 1-2, the stopper 13 has a stopper 131 at both ends in the length direction.

In this embodiment, as shown in fig. 1 to 2, in the case where the stopper 13 penetrates the first portion 121 and the second portion 122, a first end of the stopper 13 in the length direction protrudes from the first portion 121 to form the stopper 131, and a second end of the stopper 13 in the length direction protrudes from the second portion 122 to form the stopper 131.

The length of the limiting portion 131 at the first end of the limiting member 13 and the length of the limiting portion 131 at the second end of the limiting member 13 may be equal or different.

In other embodiments, as shown in fig. 7 to 8, the stopper 13 has a stopper 131 at one end in the length direction.

According to the bearing assembly provided by the embodiment of the application, through the structural design that the limiting parts 131 are arranged at the two ends of the limiting part 13 along the length direction, limiting support can be simultaneously provided at two positions of the bearing 12, and compared with single limiting, the double limiting mechanism is more stable and reliable, and the bearing 12 can be more effectively prevented from shifting or moving in the axial direction and the radial direction.

In some embodiments, as shown in fig. 3-6, the stop 13 is provided in a plurality, and the plurality of stops 13 includes a first stop 13a and a second stop 13b, the first stop 13a extending through the first portion 121 and the second stop 13b extending through the second portion 122.

Wherein a plurality means two or more, for example, in some embodiments, as shown in fig. 3-4, two stop members 13 are provided.

For example, in other embodiments, as shown in fig. 5-6, four stoppers 13 are provided.

The plurality of limiting members 13 may be divided into a first limiting member 13a and a second limiting member 13b, the first limiting member 13a and the first boss 1211 are distributed on opposite sides of the first portion 121, the first boss 1211 combines with the limiting portion 131 of the opposite side first limiting member 13a to realize limiting of the first portion 121 along the axial direction, the second limiting member 13b and the second boss 1221 are distributed on opposite sides of the second portion 122, and the second boss 1221 combines with the limiting portion 131 of the opposite side second limiting member 13b to realize limiting of the second portion 122 along the axial direction.

According to the bearing assembly provided by the embodiment of the application, through the arrangement of the first limiting piece 13a and the second limiting piece 13b, the first limiting piece 13a only needs to bear the limiting force of the first part 121, and the second limiting piece 13b only needs to bear the limiting force of the second part 122, so that the stress load of a single limiting piece 13 is reduced, the reliability and durability of the whole bearing assembly are improved, and meanwhile, the precision requirement for perforating the first part 121 and the second part 122 is reduced, thereby reducing the processing difficulty.

In some embodiments, as shown in fig. 3-4, the first limiting member 13a has limiting portions 131 at both ends in the length direction, and the second limiting member 13b has limiting portions 131 at both ends in the length direction.

According to the bearing assembly provided by the embodiment of the application, through the structural design that the two ends of the first limiting piece 13a are provided with the limiting parts 131 and the two ends of the second limiting piece 13b are provided with the limiting parts 131, the first limiting piece 13a and the second limiting piece 13b can respectively realize axial limiting at two different positions when being respectively inserted into the first part 121 and the second part 122, and the double locking mechanism greatly increases the connection strength between the limiting piece 13 and the bearing 12, and reduces loosening or falling caused by vibration, impact or long-time use, so that the stability of the whole bearing assembly is obviously improved.

In some embodiments, as shown in fig. 5-6, the first limiting member 13a has a limiting portion 131 at one end in the length direction, the other end of the first limiting member 13a in the length direction is axially opposite to the second portion 122, and the second limiting member 13b has a limiting portion 131 at one end in the length direction, and the other end of the first limiting member 13a in the length direction is axially opposite to the first portion 121.
