Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The driving shaft assembly provided by the embodiment is used for a photovoltaic tracking support system, and particularly, one end of the driving shaft assembly is connected with one driving device, and the other end of the driving shaft assembly is connected with the other driving device.
As shown in fig. 1, the transmission shaft assembly 001 according to the present embodiment includes: at least two propeller shafts 100 and at least one propeller shaft connector 200. As shown in fig. 2, two adjacent propeller shafts 100 are fixedly connected by a propeller shaft connecting member 200.
It can be understood that the propeller shafts 100 and the propeller shaft connecting members 200 are alternately distributed, the number of the propeller shaft connecting members 200 is smaller than that of the propeller shafts 100, and the difference between the numbers of the propeller shafts 100 and the propeller shaft connecting members 200 is 1.
In the drive shaft assembly 001 that above-mentioned embodiment provided, through setting up two at least drive shafts 100 and two adjacent drive shafts 100 pass through drive shaft connecting piece 200 fixed connection, like this, compare with adopting a whole axle, shortened the length of single drive shaft 100, shortened the length that each drive shaft 100 both ends were strideed across promptly, effectively reduced the degree of single drive shaft 100 middle section downwarping, reduced the degree of whole drive shaft assembly 001 middle section downwarping promptly to the influence to transmission efficiency has been reduced.
Meanwhile, in the transmission shaft assembly 001 provided by the embodiment, the existing transmission shaft is divided into the plurality of transmission shafts 100, so that the transportation is facilitated, and the length of the whole transmission shaft assembly 001 is convenient to adjust.
In order to improve bending resistance and synchronization performance at the junction of two propeller shafts 100, as shown in fig. 2 and 3, the propeller shaft 100 includes: a transmission main body shaft section 110, a transmission connecting shaft section 120 fixed at both ends of the transmission main body shaft section 110; the transmission main body shaft section 110 and the transmission connecting shaft section 120 are coaxially arranged, the transmission main body shaft section 110 is a circular shaft, and the transmission connecting shaft section 120 is a polygonal shaft. In this case, the driving connection shaft segments 120 of two adjacent driving shafts 100 are fixedly connected by the driving shaft connection member 200.
It should be noted that the cross section of the polygonal shaft is polygonal, and the cross section is perpendicular to the axis of the drive shaft 100. Since the transmission body shaft section 110 is longer, two phantom lines are used in FIG. 3 to show that the middle portion of the transmission body shaft section 110 is omitted.
The specific shape of the polygonal shaft is selected according to actual needs, such as a quadrangle, a pentagon, a hexagon, and the like. For convenience of installation, the polygonal shaft can be selected as a regular polygonal shaft. Further, the polygonal shaft is a square shaft.
In the transmission shaft assembly 001, the transmission connecting shaft section 120 is designed into a polygonal shaft, and the bending resistance and the synchronization performance of the joint of the two transmission shafts 100 are effectively improved according to the characteristics of the polygonal shaft, namely the bending resistance and the synchronization performance of the whole transmission shaft assembly 001 are improved; by designing the transmission main body shaft section 110 as a round shaft, the anti-torsion performance of the transmission shaft assembly 001 is effectively ensured, and the cost is reduced because the round shaft is convenient to process and has a smaller required diameter (the round shaft only needs to bear the torque so that the diameter can be designed to be smaller).
Therefore, the transmission shaft 100 realizes the combination of the polygonal shaft and the circular shaft, improves the bending resistance and the synchronization performance, ensures the torsion resistance, and reduces the cost.
The length of the drive shaft assembly 001 may vary from photovoltaic tracking rack system to photovoltaic tracking rack system. To flexibly adjust the length of the driveshaft assembly 001, the driveshaft adapter 200 and driveshaft section 120 are removably fixedly attached. Specifically, the detachable fixed connection may be realized by a fastener, a clamping member, or the like, which is not limited in this embodiment.
In the structure, only a certain damaged transmission shaft 100 can be replaced independently, all transmission shafts 100 do not need to be replaced, the maintenance is convenient, and the operation and maintenance cost is also reduced.
In the above-described propeller shaft assembly 001, the length of the entire propeller shaft assembly 001 is changed by increasing or decreasing the number of propeller shafts 100. However, the adjustment accuracy is low. In order to improve the adjustment accuracy, the fixed connection position of the transmission connection shaft segment 120 and the transmission shaft connection member 200 may be selected to be adjustable in the axial direction of the transmission shaft 100.
In one aspect, the selectable transmission connecting shaft segment 120 is provided with at least two first fixing structures fixedly connected to the transmission shaft connecting member 200, and the first fixing structures are sequentially distributed along the axial direction of the transmission shaft 100, or the first fixing structures are one and each first fixing structure includes at least two first fixing positions sequentially distributed along the axial direction of the transmission shaft 100.
It is understood that, if there are at least two first fixing structures sequentially distributed along the axial direction of the transmission shaft 100, the transmission connecting shaft segment 120 may be fixedly connected with the transmission shaft connecting member 200 through any one of the first fixing structures; if the first fixing structure is one and the first fixing structure includes at least two first fixing positions sequentially distributed along the axial direction of the transmission shaft 100, the transmission connecting shaft segment 120 may be fixedly connected to the transmission shaft connecting member 200 through any one of the first fixing positions.
On the other hand, the selectable transmission shaft connector 200 is provided with at least two second fixing structures fixedly connected to the transmission connecting shaft section 120, and the second fixing structures are sequentially distributed along the axial direction of the transmission shaft 100, or the second fixing structures are one and the second fixing structures have at least two second fixing positions sequentially distributed along the axial direction of the transmission shaft 100.
It is understood that, if there are at least two second fixing structures sequentially distributed along the axial direction of the transmission shaft 100, the transmission shaft connector 200 can be fixedly connected with the transmission connecting shaft section 120 through any second fixing structure; if the second fixing structure is one and the second fixing structure has at least two second fixing positions sequentially distributed along the axial direction of the transmission shaft 100, the transmission shaft connector 200 may be fixedly connected to the transmission connecting shaft section 120 through any of the second fixing positions.
The two aspects can be combined, and are selected according to actual needs, which is not limited in this embodiment.
For simplicity, the drive connecting shaft segment 120 and the drive shaft connector 200 may be detachably and fixedly connected by a fastener. At this time, the first fixing structure is the first fixing hole 121, and the second fixing structure is the second fixing hole 211.
If the first fixing structure is the first fixing hole 121 and there are at least two first fixing holes 121, all the first fixing holes 121 can be selected to be disposed on the same side of the transmission connecting shaft segment 120; as shown in fig. 3, at least two first fixing holes 121 may be alternatively provided on different sides of the transmission connecting shaft segment 120.
The first fixing hole 121 may be a circular hole or another hole. If the first fixing structure is one and the first fixing structure includes at least two first fixing positions sequentially distributed along the axial direction of the transmission shaft 100, the first fixing hole 121 may be selected to be a strip-shaped hole. In this case, the second fixing hole 211 is a circular hole to ensure the reliability of the fixed connection between the transmission connecting shaft segment 120 and the transmission shaft connecting member 200.
If there are at least two first fixing holes 121, the first fixing holes 121 may be strip-shaped holes as needed.
If the second fixing structure is the second fixing hole 211 and the number of the second fixing holes 211 is at least two, the second fixing holes 211 may be circular holes or holes with other shapes. Specifically, if the second fixing structure is one and the second fixing structure has at least two second fixing positions sequentially distributed along the axial direction of the transmission shaft 100, as shown in fig. 2 and 4, the second fixing hole 211 may be a strip-shaped hole. In this case, the first fixing hole 121 is a circular hole to ensure the reliability of the fixed connection between the transmission connecting shaft segment 120 and the transmission shaft connecting member 200.
If there are at least two second fixing holes 211, the second fixing holes 211 may be strip-shaped holes as needed.
In the above-described drive shaft assembly 001, the specific structure of the drive shaft connector 200 is selected according to actual needs. In one embodiment, to facilitate assembly and disassembly, as shown in fig. 2, driveshaft adapter 200 includes two connecting members 210, and two connecting members 210 are respectively disposed on opposite sides of driveshaft adapter shaft segment 120. One end of the connecting member 210 is fixedly connected to one transmission connecting shaft segment 120, the other end of the connecting member 210 is fixedly connected to the other transmission connecting shaft segment 120, and the two connecting members 210 and the transmission connecting shaft segment 120 are fixedly connected to each other by a fastening member sequentially penetrating through the connecting member 210, the transmission connecting shaft segment 120 and the other connecting member 210.
In the above embodiment, the two connecting members 210 may or may not be butted. It is understood that the two connection members 210 are not butted, i.e., the two connection members 210 have a gap therebetween. For ease of installation, it is preferred that the two connecting members 210 not abut.
For convenience of material selection, if the transmission connecting shaft section 120 is a square shaft, the connecting member 210 may be selected to be C-shaped steel. Of course, the shape of the connecting member 210 can also be adjusted according to the shape of the transmission connecting shaft segment 120, which is not limited in this embodiment.
In practical applications, the above-mentioned transmission shaft connector 200 may also be selected to be of other structures, for example, the transmission shaft connector 200 includes at least three connectors, the three connectors are sequentially distributed along the circumferential direction of the transmission shaft connector 200, and each connector is fixedly connected to two transmission connecting shaft segments 120.
In the above embodiment, in order to facilitate the adjustment of the length, the selectable transmission connecting shaft section 120 is provided with a first fixing hole 121, and the connecting member 210 is provided with a second fixing hole 211; the first fixing hole 121 and the second fixing hole 211 are provided for a fastener to pass through, the second fixing hole 211 is a strip-shaped hole, the length direction of the strip-shaped hole is parallel to the axial direction of the transmission shaft 100, and the first fixing hole 121 is a circular hole. Therefore, the length of the whole transmission shaft assembly 001 can be adjusted by adjusting the position of the first fixing hole 121 in the length direction of the strip-shaped hole.
It can be understood that if the second fixing hole 211 is one and a strip-shaped hole, the first fixing holes 121 of the two transmission connecting shaft segments 120 that are fixedly connected are both located in the strip-shaped hole.
In the transmission shaft assembly 001, the transmission main body shaft segment 110 and the transmission connecting shaft segment 120 are both hollow structures for weight reduction. Specifically, the transmission body shaft segment 110 and the transmission connection shaft segment 120 are both tubular structures.
Of course, at least one of the transmission main body shaft segment 110 and the transmission connecting shaft segment 120 may be selected to be a solid structure, and is not limited to the above embodiments.
In the transmission shaft assembly 001, the transmission main body shaft section 110 and the transmission connecting shaft section 120 may be of an integral structure or a split structure. To simplify installation, the transmission body shaft segment 110 and the transmission connecting shaft segment 120 may be selected to be of a unitary construction. Specifically, two ends of the transmission shaft 100 are formed into a polygonal shaft through an oil press and a die, and the polygonal shaft is the transmission connection shaft section 120. In practical applications, the optical fiber may also be manufactured by other methods, which is not limited in this embodiment.
In order to further optimize the above technical solution, the transmission shaft assembly 001 further includes a transmission seat 300, the transmission shaft 100 rotatably passes through the transmission seat 300, and the transmission seat 300 limits the transmission shaft 100 in a vertical direction.
It will be appreciated that when the drive shaft 100 includes a drive body shaft segment 110, the drive body shaft segment 110 rotatably passes through the drive socket 300. The driving holder 300 has a through-hole 310 through which the driving shaft 100 passes.
For convenience of installation, the above-described actuator base 300 may be selected to be disposed on the purlin 006 of the photovoltaic tracking bracket system. Above-mentioned purlin 006 is fixed in main shaft 005, and purlin 006 is used for fixed photovoltaic module.
In practical applications, the transmission base 300 may be disposed on the main shaft 005, and is not limited to the above embodiment.
Since a construction site generally has a slope or uneven ground, the driving shaft 100 is not absolutely parallel to the main shaft 005, and the driving socket 300 easily interferes with the rotation of the driving shaft 100. In order to avoid the above interference, the driving seat 300 is rotatably provided in a vertical plane, which is parallel to the vertical direction and is perpendicular or parallel to the axis of the driving shaft 100; the rotation end of the driving seat 300 is higher than the driving shaft 100, and a gap for the rotation of the driving seat 300 is formed between the driving seat 300 and the driving shaft 100.
Above-mentioned structure has adapted to the slope and the installation error of certain degree through rotatable mount 300, has guaranteed mount 300 and has distributed perpendicularly downwards under the action of gravity all the time to when having guaranteed that purlin 006 is rotatory to arbitrary angle, mount 300 homoenergetic limits transmission shaft 100 downwarping and will disturb size control down in controllable range, also improves mount 300's spacing effect.
In the above embodiment, if the vertical plane is perpendicular to the axis of the transmission shaft 100, it is preferable to select the rotation axis of the transmission base 300 to be parallel to the transmission shaft 100; if the vertical plane is parallel to the axis of the drive shaft 100, it is preferable to select the rotation axis of the driving socket 300 to be perpendicular to the drive shaft 100. The former is preferred for ease of installation and for proper layout.
Specifically, as shown in fig. 5, a connecting plate 700 is fixed to the purlin 006, and the transmission base 300 is rotatably disposed on the connecting plate 700 through a rotating shaft 600, wherein the rotating shaft 600 is parallel to the transmission shaft 100. In order to improve stability, the number of the connecting plates 700 is two, two ends of the rotating shaft 600 are respectively fixed to the two connecting plates 700, the transmission seat 300 is provided with a mounting hole 330 which is in running fit with the rotating shaft 600, the rotating shaft 600 is externally sleeved with a spacer 500, and the spacer 500 is located between one connecting plate 700 and the transmission seat 300, so that the transmission seat 300 is positioned in the axial direction of the rotating shaft 600.
In practical applications, the transmission seat 300 may be arranged by other structures, and is not limited to the above embodiment.
In the transmission shaft assembly 001, the transmission shaft 100 is easily abraded due to the collision between the transmission shaft 100 and the transmission seat 300, and the subsequent maintenance is complicated and difficult due to the need to replace the transmission shaft 100. In order to avoid replacing the transmission shaft 100, as shown in fig. 1 and 5, the transmission shaft assembly 001 further includes a bearing 400 sleeved on the transmission shaft 100, the bearing 400 is detachably and fixedly connected with the transmission shaft 100, and the bearing 400 rotatably penetrates through the transmission seat 300. In this case, the bearing 400 has a fitting hole 430 to be fitted with the drive shaft 100, and the drive shaft 100 is rotatably inserted through the drive holder 300 through the bearing 400, i.e., the bearing 400 is located between the drive holder 300 and the drive shaft 100, and at this time, the bearing 400 is located in the through hole 310 of the drive holder 300.
In the above embodiment, the bearing 400 protects the transmission shaft 100, and the bearing 400 is worn out first in the collision process, and the bearing 400 is directly replaced without replacing the transmission shaft 100, thereby reducing the operation and maintenance cost.
The material of the bearing 400 is selected according to actual needs. In order to reduce cost, enhance sliding performance and reduce friction, the bearing 400 may be selected to be a plastic bearing.
In order to improve the protection effect of the bearing 400, at least one side of the transmission base 300 is in limit fit with the bearing 400 in the axial direction of the bearing 400. For the convenience of installation, the bearing 400 may be provided with a limit structure 460, and the limit structure 460 may abut against one side of the transmission base 300 in the axial direction of the bearing 400. Specifically, the limiting structure 460 is a limiting flange or a limiting plate, and the like, which is not limited in this embodiment.
In order to facilitate the disassembly and assembly and replacement of the bearing 400, as shown in fig. 5, 7-9, the bearing 400 includes at least two bearing sub-bodies 410 which are sequentially butted along the circumferential direction, and two adjacent bearing sub-bodies 410 are detachably and fixedly connected. In this way, the at least two bearing split bodies 410 tightly hold the transmission shaft 100 through fixed connection, and fixed connection with the transmission shaft 100 is realized; in this case, a bearing retainer ring is not required to be arranged to axially limit the bearing 400, so that the structure is simplified; moreover, the bearing split 410 can be replaced independently, so that the operation and maintenance cost is reduced.
Specifically, in order to simplify the disassembly and assembly, the bearing 400 includes two bearing split bodies 410, and the two bearing split bodies 410 are detachably and fixedly connected by a fastener.
