Description

[Technical Field]

[0001] This utility model relates to the field of solar tracking systems, specifically to a stamped ball bearing seat device for multi-point mechanical transmission of photovoltaic brackets. [Background Technology]

[0002] With the continuous expansion of global photovoltaic installations, the market demand for tracking brackets is also increasing year by year. As one of the key components that ensures the photovoltaic tracking bracket can rotate accurately and track light in real time, the performance of the bearing housing system directly affects the stability, tracking accuracy, and power generation efficiency of the bracket.

[0003] In existing technologies, the principle of multi-point mechanical transmission photovoltaic tracking brackets relies on a transmission rod to drive the main shaft to rotate. Therefore, both the transmission rod and the main shaft need to be equipped with corresponding bearings. Ball bearings, due to their excellent omnidirectional rotation characteristics, not only provide good support and protection for the main shaft and transmission shaft, but also adapt to the installation and commissioning requirements of different slopes on site. Their usage frequency in the tracking bracket market is gradually increasing. Currently, most ball bearing housing designs adopt a multi-part assembly form. Multiple parts (such as column top housing, lower bearing housing, upper bearing housing, transmission shaft bearing housing, etc.) formed by welding or extrusion are assembled to form a complete bearing housing system. Although such bearing housings can meet basic requirements, the multi-part collaborative bearing housing system is not only structurally complex and difficult to assemble and debug, but also has low production and cost-effectiveness, weakening the market competitiveness of tracking brackets.

[0004] Therefore, designing a bearing housing that is simple and reliable in structure, easy to install and debug, and competitive in terms of cost-effectiveness is of great significance for improving the applicability and competitive advantage of tracking brackets and ensuring the stable operation of photovoltaic tracking brackets. In view of this, this case study addresses the above issues in depth, leading to this proposal. [Utility Model Content]

A second right drawing groove is also formed between the second through hole and the third right punch, and a fourth right punch is formed in the second right drawing groove.

[0011] Furthermore, the left and right sides of the Y-shaped back plate are respectively formed with a left flange and a right flange.

[0012] Furthermore, a letter symbol reinforcing rib is provided below the second through hole.

[0015] The advantages of this utility model are:

[0016] 1. The stamped ball bearing housing device consists of only two metal parts: a flip cover and a bearing housing. This avoids the slippage problem that may occur between the main shaft and the main shaft ball bearing. Furthermore, the main shaft ball bearing and the drive shaft ball bearing can be easily installed by fastening the assembly with four sets of flange bolts.

[0028] Reference Appendix Figure 1-5As shown, this utility model provides a stamped ball bearing seat device 100 for multi-point mechanical transmission of photovoltaic brackets, including a flip cover plate 1 and a bearing seat 2. A first through hole 4 is formed between the flip cover plate 1 and the bearing seat 2 to install a main shaft ball bearing 200 and a main shaft 300, so as to satisfy the free rotation of the main shaft 300 in any direction and adapt to the bracket installation requirements of different slopes. The flip cover plate 1 and the bearing seat 2 are detachably connected by two fasteners.

[0029] In this utility model, the flip cover 1 is a stamped integral molded part; the flip cover 1 includes a bearing cover surface 11, the inner surface of the bearing cover surface 11 is a spherical surface adapted to the spindle ball bearing 200, adapted to the free rotation of the spindle ball bearing 200 inside; the two ends of the bearing cover surface 11 are rounded to prevent the spindle ball bearing 200 from being scratched by the sharp corners while rotating on the bearing cover surface 11, and to prevent the appearance of the spindle ball bearing 200 from being damaged. The two ends of the bearing cover surface 11 are smoothly transitioned and tightened inward to form a left hanging ear 12 and a right hanging ear 13. The left hanging ear 12 includes a first left flat plate 121 and a second left flat plate 122, and a left assembly gap 123 for the insertion of the left insert plate 212 is formed between the first left flat plate 121 and the second left flat plate 122. The right hanging ear 13 includes a first right flat plate 131 and a second right flat plate 132, and a right assembly gap 133 for the insertion of the right insert plate 213 is formed between the first right flat plate 131 and the second right flat plate 132.

[0030] In this invention, the bearing housing 2 includes a first bearing support 21 and a second bearing support 22 that are connected back-to-back. Compared to the scenario of independent support for a single bearing housing, the back-to-back installation of the first bearing support 21 and the second bearing support 22 improves the overall compressive strength and torsional performance of the bearing housing device. The first bearing support 21 includes a back plate 211. The upper part of the back plate 211 is provided with a left insert plate 212 that is inserted into the left assembly gap 123 and a right insert plate 213 that is inserted into the right assembly gap 133. A supporting spherical surface 214 for supporting the main shaft ball bearing 200 is formed between the left insert plate 212 and the right insert plate 213. The supporting spherical surface 214 is a stamped half-supporting spherical surface 214. The end face of the half-supporting spherical surface 214 is rounded to prevent the main spindle ball bearing 200 from being scratched by the edges of the supporting spherical surface 214 while rotating inside the supporting spherical surface 214, thus damaging the appearance of the main spindle ball bearing 200. The left and right sides of the supporting spherical surface 214 are open-shaped flanges to prevent the main spindle ball bearing 200 from being stuck and unable to rotate by the spherical forming error of the supporting spherical surface 214 when rotating inside the bearing seat 2. The structure of the second bearing support 22 is the same as that of the first bearing support 21.

[0031] In this utility model, the first left plate 121 is provided with a first left punch 1211, the second left plate 122 is provided with a second left punch, the left insert plate 212 is provided with a first left drawing groove 2121, and a third left punch 2122 is provided in the first left drawing groove 2121; the first right plate 131 is provided with a first right punch, the second right plate 132 is provided with a second right punch 1321, the right insert plate 213 is provided with a first right drawing groove 2131, and a third right punch 2132 is provided in the first right drawing groove 2131. The back sides of the first left draw-in groove 2121 of the first bearing support 21 and the first right draw-in groove 2131 of the second bearing support 22 abut against each other, and the back sides of the first right draw-in groove 2131 of the first bearing support 21 and the first left draw-in groove 2121 of the second bearing support 22 abut against each other, eliminating the gap between the upper parts of the two bearing supports when the first bearing support 21 and the second bearing support 22 are installed back-to-back and locked on the column 500, avoiding deformation and displacement of the ball bearing support surface caused by the gap after back-to-back installation and locking, and further ensuring that the rotational fit of the ball bearing on the bearing housing 2 is not affected.

[0032] The first left punch 1211, the second left punch, and the third left punch 2122 are used to install the first flange bolt fastening assembly 31; the first right punch 1321, the second right punch 1321, and the third right punch 2132 are used to install the second flange bolt fastening assembly 32, thereby realizing the detachable connection between the flip cover plate 1 and the bearing seat 2.

[0033] In this invention, the back plate 211 is a Y-shaped back plate 211, and a second through hole 2113 for assembling the drive shaft ball bearing 400 is formed through the middle of the Y-shaped back plate 211. The shape of the second through hole 2113 is the same as that of the drive shaft ball bearing 400, and it can be any type of hole, as long as it matches the cross-section of the drive shaft ball bearing 400, so that the drive shaft ball bearing 400 can rotate freely in any direction, adapting to the installation requirements of photovoltaic brackets on different slopes; the design of the second through hole 2113 allows the drive shaft ball bearing 400 to be installed without the need for a separate drive shaft ball bearing seat.

[0034] In this invention, a second left drawing groove 2123 is formed between the second through hole 2113 and the third left punch 2122, and a fourth left punch 2124 is formed within the second left drawing groove 2123. Similarly, a second right drawing groove 2133 is formed between the second through hole 2113 and the third right punch 2132, and a fourth right punch 2134 is formed within the second right drawing groove 2133. This design of the drawing groove and punches allows for the installation of the third flange bolt fastening assembly 33 and the fourth flange bolt fastening assembly 34. It enables the two bearing supports to form a single unit, and also allows the fourth left punch 2124 and the fourth right punch 2134 to fit more tightly after the bearing supports are assembled, reducing the internal spherical surface error formed by the assembly, thereby reducing the amount of movement of the drive shaft ball bearing 400 within the through hole 2113.

[0035] In this invention, the Y-shaped back plate 211 has a left flange 2111 and a right flange 2112 on its left and right sides, respectively. The design of the left flange 2111 and right flange 2112 strengthens the structural rigidity and improves the wind resistance of the support frame, without affecting maintenance after opening the flip cover 1, thus balancing ease of maintenance with improved overall structural strength. A certain space is reserved between the left flange 2111 and the top of the Y-shaped back plate 211 for subsequent maintenance of the main shaft or main shaft ball bearing 200 by opening the flip cover 1.

[0036] In this utility model, a letter symbol reinforcing rib 215 is provided below the second through hole 2113, which not only strengthens the strength of the lower part of the Y-shaped back plate 211 that would be weakened after punching, but also takes into account the uniqueness and aesthetics of the Y-shaped back plate 211.

[0037] In this invention, two vertical slots 216 are provided below the letter symbol reinforcing rib 215. The vertical slots 216 are located at the lower part of the Y-shaped back plate 211 and are used to fasten fasteners, thus fixing the bearing seat 2 device on the column 500. The vertical slots 216 allow for height adjustment of the Y-shaped back plate 211 in the vertical direction of the column 500. A horizontal slot 501 is provided on the column 500, allowing for free adjustment of the Y-shaped back plate 211 in the horizontal direction of the column 500. The design of the double vertical slots 216, combined with the double horizontal slots 501 on the column 500, eliminates the need for other adjusting parts, easily satisfying free adjustment in both the horizontal and vertical directions. This solves the problems of redundant parts and cumbersome installation and debugging steps in the bearing seat 2 device, improving the convenience of installation and debugging.

[0038] In this invention, the fasteners include a first flange bolt fastening assembly 31 for locking the left mounting lug 12 and the left insert plate 212, a second flange bolt fastening assembly 32 for locking the right mounting lug 13 and the right insert plate 213, a third flange bolt fastening assembly 33 for locking through the fourth left punch hole 2124 of the first bearing support 21 and the fourth right punch hole 2134 of the second bearing support 22, and a fourth flange bolt fastening assembly 34 for locking through the fourth right punch hole 2134 of the first bearing support 21 and the fourth left punch hole 2124 of the second bearing support 22. When the spindle ball bearing 200 or the spindle needs maintenance or replacement, only one of the first flange bolt fastening assembly 31 or the second flange bolt fastening assembly 32 needs to be disassembled, and the flange bolt fastening assembly of the other mounting lug needs to be loosened, so that the flip plate 1 can be opened at a certain angle, making it easy to take out the spindle ball bearing 200 or the spindle, thus improving the convenience of later maintenance.

[0039] In this utility model, the stamped ball bearing seat device 100 also includes a spindle ball bearing 200.

[0040] The stamped ball bearing seat device 100 of this utility model has at least the following beneficial technical effects:

[0041] The stamped ball bearing housing device 100 consists of only two metal parts: a flip cover plate 1 and a bearing housing 2. This avoids the slippage problem that may occur between the main shaft 300 and the main shaft ball bearing 200. Furthermore, the main shaft ball bearing 200 and the drive shaft ball bearing 400 can be easily installed by fastening the assembly with four sets of flange bolts. This greatly reduces the types and number of parts, optimizes the installation steps and efficiency of the photovoltaic system, and is of great help in enhancing the market competitiveness of the multi-point mechanical linkage tracking bracket.

[0042] Second, by designing the bearing housing 2, which includes a first bearing support 21 and a second bearing support 22 that are connected back to back, the back-to-back installation method of the two bearing supports improves the compressive strength and torsional performance of the bearing housing device as a whole compared to the use scenario of independent support of a single bearing housing. The double bearing support adopts local drawing at the back-to-back interlocking point to avoid the local deformation of the bearing support after interlocking due to the existence of back-to-back gap, which would weaken the overall rigidity.

[0043] 3. The stamping forming ball bearing housing device 100 adopts metal stamping process, which is different from the traditional welding or extrusion process. The stamping process is not only simple in process, which meets the requirements of one-piece forming of bearing housing 2, but also greatly improves production efficiency and reduces production costs.

[0044] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
