Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0036] Please refer to Figures 1-6 This embodiment provides a chain drive assembly 300, which includes a chain 200 and a sprocket 100;

[0037] The sprocket 100 is used to mesh with the chain 200 for transmission. The sprocket 100 is configured with a first meshing tooth set 110 and a second meshing tooth set 120 on its outer periphery. The first meshing tooth set 110 and the second meshing tooth set 120 are spaced apart along the axial direction of the sprocket 100, so that the first meshing tooth set 110 and the second meshing tooth set 120 are relatively staggered in the axial direction. This allows the first meshing tooth set 110 to mesh with the inner chain plate 210 of the chain 200, and the second meshing tooth set 120 to mesh with the outer chain plate 220 on one side of the chain 200.

[0038] Therefore, when the sprocket 100 adopts the above-described structure, the chain drive assembly 300 can be configured such that the first meshing tooth set 110 meshes with the inner chain plate 210 of the chain 200, and the second meshing tooth set 120 meshes with the outer chain plate 220 on one side of the chain 200.

[0039] Please refer to Figures 1-6 The working principle of the chain drive assembly 300 is as follows:

[0040] The chain drive assembly 300 uses a first meshing tooth group 110 that meshes with the inner chain plate 210 of the chain 200, and a second meshing tooth group 120 that meshes with the outer chain plate 220 on one side of the chain 200. This arrangement increases the number of contact points between the sprocket 100 and the chain 200, thereby increasing the stability of the transmission, increasing the transmission torque, and reducing transmission noise during the transmission process.

[0041] In addition, this configuration allows for the increase of the length of a single link while keeping the chain 200 length unchanged. This increases the number of links added to the chain 200, thereby optimizing the structure, reducing the weight of the chain 200, and consequently reducing energy consumption during transmission.

[0042] Further, please refer to Figures 1-6In this embodiment, the sprocket 100 is configured with two sets of second meshing teeth 120, distributed on both sides of the first meshing tooth set 110 along the axial direction of the sprocket 100. Each of the two sets of second meshing teeth 120 meshes with an outer chain plate 220 on one side of the chain 200. This arrangement ensures that both outer chain plates 220 on both sides of the chain 200 can mesh with the sprocket 100, thereby improving the stability of the transmission.

[0043] When configuring the sprocket 100 described above, the sprocket 100 may include a main body 101 and a meshing disc 102. The outer periphery of the main body 101 is provided with a first meshing tooth set 110; the meshing disc 102 is detachably connected to the main body 101, and the outer periphery of the meshing disc 102 is provided with a second meshing tooth set 120. With this arrangement, based on the structure of the main body 101, the meshing disc 102 can be freely combined and connected with the main body 101 as needed. Moreover, with this arrangement, the meshing disc 102 can be installed on both sides or one side of the main body 101 along the axial direction of the main body 101 as needed.

[0044] Further, please refer to Figures 1-6 In this embodiment, as can be seen from the above, the chain drive assembly 300 can reduce the overall structural weight by adopting the above structural configuration. In addition, the inner chain plate 210 can be provided with a first weight reduction hole 211, the outer chain plate 220 can be provided with a second weight reduction hole 221, and the main body 101 can be provided with a third weight reduction hole 103. Through this configuration, the overall structural weight of the chain drive assembly 300 can be further reduced, thereby helping to reduce operating power consumption.

[0045] Based on the above, please refer to Figures 1-6 In this embodiment, when configuring the first meshing tooth group 110, the first meshing tooth group 110 includes a plurality of first meshing teeth 111 arranged around the axis of the sprocket 100; while the second meshing tooth group 120 includes a plurality of second meshing teeth 121 arranged around the axis of the sprocket 100. This arrangement allows the inner chain plate 210 to mesh with the plurality of first meshing teeth 111, while the outer chain plate 220 meshes with the plurality of second meshing teeth 121, thereby increasing the number of transmission contact points between the chain 200 and the sprocket 100 during transmission, thus improving its stability.

[0046] Furthermore, in this embodiment, based on the above-described structure, to increase the stability of the engagement between the sprocket 100 and the chain 200, an outer chain plate mating portion 104 for engaging with the outer chain plate 220 is provided between any two adjacent second meshing teeth 121 along the axial direction of the sprocket 100. Specifically, the outer chain plate mating portion 104 includes a mating plane 105 that engages with the bottom surface of the outer chain plate 220, and arc-shaped mating surfaces 106 disposed at both ends of the mating plane 105 along the axial direction of the sprocket 100.

[0047] It should be noted that this configuration allows the outer chain plate mating part 104 to be adapted to the conventional outer chain plate 220 structure in the prior art, and can improve the stability of its mating and reduce the operating noise during its transmission process.

[0048] Taking the aforementioned sprocket 100 as an example, which includes two sets of second meshing tooth groups 120 distributed on both sides of the first meshing tooth group 110, this arrangement allows the outer chain plates 220 on both sides of the chain 200 in the chain drive assembly 300 to mesh with the sprocket 100. In other words, this arrangement forms a single-row chain with three rows of meshing with the sprocket 100, where the middle inner chain plate 210 and the outer chain plates 220 on both sides mesh with the sprocket 100. Compared to the single-row, single-column meshing method in existing technologies, the three-column meshing method can double the number of teeth on the equally pitched circular sprockets 100, thereby greatly reducing the polygonal effect of the chain 200 during operation; it can also double the pitch of the chain 200 meshing with the same number of teeth, reducing the number of chain 200 links in the entire system, reducing the weight of the entire chain 200 system, improving the safety factor of the chain 200 during operation, and at the same time reducing the axial pressure ratio of the chain 200 during operation, thus improving wear resistance and service life.

[0049] Furthermore, based on the aforementioned chain drive assembly 300, please refer to... Figures 1-6 This embodiment also provides a drive system, which includes a power unit and the chain drive assembly 300 described above; the power unit is connected to the sprocket 100 in a drive connection.

[0050] It should be noted that this drive system is used in heavy equipment to meet the needs of long-distance transmission or conveying in heavy equipment. Moreover, by adopting the aforementioned chain drive component 300, it can reduce structural weight, improve transmission stability, reduce transmission noise, and reduce operating power consumption.

[0051] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
