Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic tracking support that prevents bearing slippage. Background Technology
[0002] Existing photovoltaic tracking brackets add an extra pad between the plastic bearing and the main shaft. The pad is snapped into the plastic bearing, so that the pad and the main shaft abut against each other. The friction force is used to ensure the synchronous rotation between the plastic bearing and the main shaft. However, when the plastic bearing is subjected to a large force, the pad is easily sheared and broken or fails, causing the bearing to run off.
[0003] Therefore, it is necessary to provide a new photovoltaic tracking bracket that prevents bearing slippage in order to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a photovoltaic tracking bracket that prevents bearings from slipping off, which can effectively avoid jamming caused by the main shaft and bearings not rotating in sync.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A photovoltaic tracking bracket for preventing bearing slippage includes a main shaft and a bearing assembly. The bearing assembly includes a bearing and a bearing housing. The bearing is rotatably disposed within the bearing housing and sleeved on the outer periphery of the main shaft.
[0007] The photovoltaic tracking bracket also includes a crimping member installed on the main shaft. The crimping member includes a main body and a side plate. The side plate extends from the main body along the axial direction of the main shaft and is inserted between the bearing and the main shaft.

[0010] As a further improvement of this utility model, the base is parallel to the side plate, the height of the base is higher than that of the side plate, and the side plate abuts against the bearing assembly.
[0011] As a further improvement of the present invention, the photovoltaic tracking bracket further includes a gasket, which is at least partially sandwiched between the main shaft and the side plate.
[0012] As a further improvement of the present invention, the gasket includes a first plate and a second plate. The second plate protrudes from the first plate to form a stepped shape with a high center and low sides in the axial direction of the main shaft. The first plate is at least partially sandwiched between the main shaft and the side plate, and the side plate abuts against the second plate in the axial direction.
[0013] As a further improvement of the present invention, the second plate includes a top wall and two side walls located on both sides of the top wall in the axial direction, and the end of the side plate away from the side plate abuts against the side wall.
[0014] As a further improvement of the present invention, the pressing member includes two side plates, one of which is relatively close to the bearing assembly and at least partially sandwiched between the first plate and the bearing, and the other side plate is relatively far away from the bearing assembly. The first plate is at least partially in contact with the two side plates of the pressing member.
[0015] As a further improvement of the present invention, the photovoltaic tracking bracket also includes a connector, the connector being U-shaped, the connector being fixedly connected to the crimping member and at least partially conforming to the main shaft, the side of the side plate away from the base being at least partially adapted to and abutting against the main shaft, and the connector and the crimping member cooperating to surround the main shaft.
[0016] As a further improvement of the present invention, the connector includes a surrounding part and a connecting part, the surrounding part conforming to at least a portion of the outer wall of the main shaft, and the connecting part passing through the base and being fixed.
[0017] Compared to existing technologies, the advantages of this photovoltaic tracking bracket for preventing bearing slippage are as follows: A pressing component installed on the main shaft is provided. The pressing component includes a main body and a side plate. The side plate extends axially along the main shaft and is inserted between the bearing and the main shaft to fill the gap between them. This ensures the bearing is completely confined within the bearing housing and is less prone to failure. This photovoltaic tracking bracket effectively prevents bearing slippage using existing materials, avoiding jamming caused by the main shaft and bearing not rotating in sync. Furthermore, it is simple to install, requires no replacement of the plastic bearing, and reduces labor and material costs. Attached Figure Description

[0027] Please see Figures 1 to 6 As shown, this embodiment discloses a photovoltaic tracking bracket to prevent bearing slippage, including a main shaft 1, a bearing assembly 2, and a pressing member 3. Both the bearing assembly 2 and the pressing member 3 are disposed on the main shaft 1. The bearing assembly 2 includes a bearing 21 and a bearing housing 22. The bearing 21 is rotatably disposed within the bearing housing 22 and sleeved on the outer periphery of the main shaft 1. The pressing member 3 is at least partially clamped between the bearing 21 and the main shaft 1 to fill the gap between the bearing 21 and the main shaft 1, so that the bearing 21 and the main shaft 1 can rotate synchronously.
[0028] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the crimping member 3 includes a main body 30 and side plates 33. The side plates 33 extend from the main body 30 along the axial direction of the main shaft 1 and are inserted between the bearing 21 and the main shaft 1. In this embodiment, the crimping member 3 is integrally formed and has high strength. The main body 30 includes a base 31 and two side plates 32. The two side plates 32 are vertically disposed on both sides of the base 31. The edge contours of the side plates 32 mate with the main shaft 1 to facilitate the installation of the crimping member 3 onto the main shaft 1. The two side plates 33 extend from the two side plates 32 in opposite directions along the axial direction of the main shaft 1. Further, at least one side plate 33 extends from the side plate 32 along the axial direction of the main shaft 1 and is inserted between the bearing 21 and the main shaft 1. With this arrangement, the side plates 33 are inserted between the bearing 21 and the main shaft 1 to increase the friction between the bearing 21 and the main shaft 1, ensuring that the bearing 21 and the main shaft 1 rotate synchronously. The two side plates 32 abut against the bearing 21 respectively, which are used to limit the bearing 21 and prevent the bearing 21 from dislodging from the bearing housing 22.
[0029] Please see Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the bearing 21 is a double-shoulder bearing, and the photovoltaic tracking bracket includes two pressing parts 3. The two pressing parts 3 are disposed above the main shaft 1 and are respectively located on both sides of the bearing assembly 2. The two pressing parts 3 include two side plates 33 that extend relative to each other along the axial direction of the main shaft 1. The two side plates 33 are respectively inserted between the bearing 21 and the main shaft 1 by extending from the side plate 32 along the axial direction of the main shaft 1.
[0030] In other embodiments, the bearing 21 is a single-shoulder bearing, and the photovoltaic tracking bracket includes a press member 3 located on one axial side of the bearing assembly 2, and the press member 3 extends from the side plate 32 along the main shaft 1 near the side plate 33 of the bearing 21 and is inserted between the bearing 21 and the main shaft 1.
[0031] Please see Figure 1 , Figure 2 and Figure 4 As shown, the photovoltaic tracking bracket in this embodiment also includes a shim 4, which is used to fill the gap between the side plate 33 and the main shaft 1 when the thickness of the side plate 33 of the pressing member 3 cannot meet the requirements. The shim 4 is at least partially sandwiched between the main shaft 1 and the side plate 33, and the thickness of the shim 4 can be set according to the actual situation.
[0032] Please see Figure 3 , Figure 4 and Figure 6 As shown, the gasket 4 includes a first plate 41 and a second plate 42. The second plate 42 protrudes from the first plate 41 to form a stepped shape with a higher center and lower sides in the axial direction of the main shaft 1. The first plate 41 is at least partially sandwiched between the main shaft 1 and the side plate 33, and the second plate 42 is at least partially sandwiched between the main shaft 1 and the bearing 21. The side plate 33 abuts against the second plate 42 in the axial direction. Furthermore, the thickness of the side plate 33 is the same as the thickness of the second plate 42. This arrangement ensures a high degree of tightness in the connection between the main shaft 1, the bearing 21, the side plate 33, and the gasket 4.
[0033] Please see Figure 3 and Figure 6 As shown, the upper surface of the first plate 41 is lower than the upper surface of the second plate 42. The second plate 42 includes a top wall 421 and two side walls 422 located on both sides of the top wall 421 in the axial direction. The side plate 33 sandwiched between the first plate 41 and the bearing 21 has one end away from the side plate 32 abutting against the side wall 422 to form mutual limiting between the pressing member 3 and the gasket 4, which facilitates installation.
[0034] Please see Figures 1 to 4As shown, since the bearing 21 in this embodiment is a double-shoulder bearing, and both sides of the bearing assembly 2 are provided with pressing members 3, the first plate 41 is adapted to the pressing members 3 on both sides respectively. The pressing member 3 includes two side plates 33, one side plate 33 is relatively close to the bearing assembly 2 and is at least partially sandwiched between the first plate 41 and the bearing 21, and the other side plate 33 is relatively far away from the bearing assembly 2. Both side plates 33 are in close contact with the first plate 41. The two side plates 33 of the two pressing members 3, which are close to each other, abut against the two side walls 422 of the gasket 4 respectively. This arrangement improves the installation adaptability and stability of the pressing member 3 and the gasket 4.
[0035] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, two side plates 32 extend downward from the base 31, and at least part of the side plate 32 away from the base 31 is adapted to and abuts against the main shaft 1. Further, the pressing member 3 has a symmetrical structure, with the two side plates 32 extending vertically downward from both ends of the base 31 along the axial direction of the main shaft 1, and at least part of the lower contour of the side plate 32 is adapted to and abuts against the main shaft 1. This arrangement facilitates the limiting installation of the pressing member 3. The base 31 is parallel to the side plate 33, and the height of the base 31 is higher than that of the side plate 33. At least part of the side plate 33 abuts downward against the main shaft 1, and the side plate 32 near the bearing assembly 2 abuts against the bearing assembly 2. Specifically, the two side plates 33 extend vertically from the middle of the two side plates 32 towards opposite sides. This configuration not only fills the gap between the bearing 21 and the spindle 1, but also increases the contact area between the pressing part 3 and the spindle 1, thereby improving the connection stability and support strength. The side plate 32 can act as a stop, saving the blocking parts that are usually added to the outside of the bearing 21, and preventing the bearing 21 from falling off relative to the bearing seat 22.
[0036] Please see Figures 1 to 3 As shown, the photovoltaic bracket in this embodiment also includes a connector 5, which is U-shaped. The connector 5 is fixedly connected to the crimping member 3 and at least partially conforms to the main shaft 1. The connector 5 and the crimping member 3 cooperate to surround the main shaft 1. The connector 5 includes a surrounding portion 51 and a connecting portion 52. The surrounding portion 51 conforms to at least a portion of the outer wall of the main shaft 1, and the connecting portion 52 is fixedly connected to the crimping member 3. Further, the surrounding portion 51 is relatively flat to better conform to the main shaft 1 for positioning, and the connecting portion 52 is cylindrical to enhance the connection strength with the crimping member 3. In this embodiment, the base 31 is provided with a through hole 311, and the outer periphery of the connecting portion 52 is provided with threads. The connecting portion 52 passes through the through hole 311 from bottom to top. A nut is screwed into the connecting portion 52 from the side of the base 31 away from the main shaft 1 and tightened to fix the crimping member 3 and the connector 5 together. The connector 5 and the crimping member 3 hug the main shaft, and then cooperate with the bearing 21 to rotate with the main shaft 1. In this embodiment, the connector 5 is a U-bolt.
[0037] Please see Figure 1 and Figure 2 As shown, the photovoltaic tracking bracket in this embodiment also includes a column top seat 6 and a synchronous shaft assembly 7. The bearing assembly 2 is disposed above the column top seat 6, and the synchronous shaft assembly 7 is disposed below the column top seat 6. Specifically, the synchronous shaft assembly 7 includes a synchronous shaft bearing seat 71, a synchronous shaft bearing 72, and a synchronous shaft. The synchronous shaft bearing 72 is slidably disposed within the synchronous shaft bearing seat 71 and sleeved on the outer periphery of the synchronous shaft.
[0038] In summary, compared with existing technologies, the photovoltaic tracking bracket for preventing bearing slippage of this utility model has the following advantages: A pressing component 3 is installed on the main shaft 1. The pressing component 3 includes a main body 30 and a side plate 33. The side plate 33 extends axially along the main shaft 1 and is inserted between the bearing 21 and the main shaft 1 to fill the gap between them, ensuring that the bearing 21 is completely confined within the bearing seat 22 and is less prone to failure. This photovoltaic tracking bracket effectively prevents the bearing 21 from slipping off using existing materials, avoiding jamming caused by the main shaft 1 and bearing 21 not rotating in sync. Furthermore, it is simple to install, requires no replacement of the plastic bearing, and reduces labor and material costs.
