[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the related art, the engine is usually used as a power output source to drive the corresponding actuator to perform the corresponding action. Usually, a transmission assembly is configured between the engine and the actuator to realize power transmission. The transmission assembly usually adopts a reducer and a coupling coupled to the reducer. This transmission structure can only realize a single power transmission and it is difficult to meet the demand of transmitting power to multiple actuators at the same time.

[0028] Based on this, the applicant conducted in-depth research on how to solve the technical problem of the single power transmission mode of the transmission component.

[0029] See also Figure 1 In the first aspect of the present application, there is provided a transmission assembly 100, comprising a reducer 10 and a half-coupling 20 coupled to the reducer 10, wherein the outside of the half-coupling 20 can participate in flexible transmission, that is, the half-coupling 20 can not only realize its axial rotational power transmission (the first type of power transmission), but also participate in flexible transmission to form a flexible transmission mechanism in combination with an external flexible member to realize the second type of power transmission.

[0030] The transmission assembly 100 proposed in this application is described in detail below.

[0031] The reducer 10 may be used to receive the rotational motion provided by the power component 200 (engine) and perform speed reduction processing on this basis.

[0032] The half coupling 20 may be coupled to the input shaft or the output shaft of the reducer 10 to achieve power transmission.

[0033] It is worth noting that the half coupling 20 includes a main body coupled with the reducer 10 and a transmission structure 22 protruding from the outside of the main body. The transmission structure 22 is configured to be able to participate in flexible transmission.

[0034] It should be noted that flexible transmission generally refers to a transmission consisting of two or more transmission wheels and an intermediate annular flexible member, through which motion and power are transmitted between the transmission wheels.

[0035] The transmission structure 22 is configured to be able to participate in the flexible transmission, that is, the transmission structure 22 can participate therein as a “transmission wheel” in the flexible transmission.

[0036] It can be understood that by setting the outer part of the half coupling 20 as the "transmission wheel" in the flexible transmission, it can realize the rotational power transmission along its axis and the power transmission of the flexible transmission.

[0037] That is, the transmission assembly 100 has at least two power transmission modes, and the transmission assembly 100 as a whole can be more flexible and have various power transmission modes to meet the requirements of transmitting power to at least two actuators.

[0038] Please continue reading Figure 1 In some embodiments, two half-couplings are provided, and the two half-couplings 20 are coupled to the two ends of the reducer 10 respectively;

[0039] One of the half couplings 20 is used for driving connection with the output shaft of the external power component 200 , and the other half coupling 20 is used for driving connection with the transmission shaft of the external transmission component 300 .

[0040] Specifically, one of the half couplings 20 may be coupled to the input end of the reducer 10 and connected to the output shaft of the power member 200 (engine), and the rotational motion provided by the engine is transmitted to the reducer 10 through the half coupling 20 .

[0041] Furthermore, another half coupling 20 is coupled to the output end of the reducer 10 and connected to the output shaft of the reducer 10 . The power processed by the reducer 10 is transmitted to the external transmission member 300 through the half coupling 20 .

[0042] It can be understood that the two half-couplings 20 can independently participate in different flexible transmissions, providing higher flexibility.

[0043] Exemplarily, it can be that the two half-couplings participate in two independent chain drives respectively; it can also be that the two half-couplings participate in two independent belt drives respectively; it can also be that one half-coupling participates in the belt drive and the other half-coupling participates in the chain drive.

[0044] Of course, each half coupling 20 can select different transmission modes according to needs to adapt to various application scenarios. The flexibility and versatility of this structure enable the transmission system to better adapt to different work requirements and improve the versatility and adaptability of the system.

[0045] Please continue reading Figure 1 In some embodiments, the transmission structure 22 is a wheel surface that can participate in the transmission of a belt transmission mechanism, and the wheel surface can be frictionally transmitted with an external transmission belt.

[0046] It can be understood that the design of the wheel surface allows it to effectively contact the transmission belt to achieve controllable friction transmission. The shape and material selection of the wheel surface are flexibly set taking into account factors such as transmission efficiency, wear resistance and stability, and are not limited here.

[0047] By configuring the transmission structure 22 as a wheel surface, the transmission structure 22 can effectively participate in the belt transmission mechanism to achieve reliable power transmission.

[0048] That is to say, the design of this embodiment enables the transmission structure 22 to participate in the friction-type transmission mechanism and be connected to the external transmission belt more flexibly.

[0049] Moreover, by adjusting the tension of the transmission belt or other parameters, the transmission effect of the transmission structure 22 can be regulated to adapt to different workloads and transmission requirements. The implementation of this friction type transmission increases the adjustability and adaptability of the transmission system, making it more versatile.

[0050] Please continue reading Figure 1 In some embodiments, the transmission structure 22 is a wheel surface that can participate in the transmission of a belt transmission mechanism, and the wheel surface can engage with an external transmission belt.

[0051] It is understandable that the design of the wheel surface allows it to effectively engage with the transmission belt to achieve a controllable meshing transmission. Of course, the shape and tooth profile of the wheel surface are flexibly set in consideration of factors such as transmission efficiency, wear resistance and stability, and are not limited here.

[0052] By configuring the transmission structure 22 as a wheel surface, the transmission structure 22 can effectively participate in the belt transmission mechanism to achieve reliable power transmission.

[0053] That is to say, the design of this embodiment enables the transmission structure 22 to participate in the meshing transmission mechanism and be connected to the external transmission belt more flexibly.

[0054] Moreover, by adjusting the tension of the transmission belt, the design of the teeth or other parameters, the transmission effect of the transmission structure 22 can be adjusted to adapt to different workloads and transmission requirements. The implementation of meshing transmission increases the adjustability and adaptability of the transmission system, making it more versatile.

[0055] Please continue reading Figure 1 In some embodiments, the transmission structure 22 is a sprocket surface that can participate in the transmission of the chain transmission mechanism, and the sprocket surface can engage with an external transmission belt for transmission.

[0056] It is understandable that the design of the sprocket surface allows it to effectively mesh with the chain to achieve a controllable meshing transmission. Of course, the shape and tooth profile of the sprocket surface are flexibly set in consideration of factors such as transmission efficiency, wear resistance and stability, and are not limited here.

[0057] By configuring the transmission structure 22 as a chain tooth surface, the transmission structure 22 can effectively participate in the chain transmission mechanism to achieve reliable power transmission.

[0058] That is to say, the design of this embodiment enables the transmission structure 22 to participate in the meshing transmission mechanism and be connected with the external chain drive more flexibly.

[0059] Moreover, by adjusting the tension of the transmission chain, the design of the chain tooth surface or other parameters, the transmission effect of the transmission structure 22 can be regulated to adapt to different workloads and transmission requirements. The implementation of meshing transmission increases the adjustability and adaptability of the transmission system, making it more versatile.

[0060] Please continue reading Figure 1 In some embodiments, the main body and the transmission structure 22 are an integrated structure.

[0061] It can be understood that there is no obvious separation or connection interface between the main body and the transmission structure 22, forming an integrated structure, which helps to improve the stability and durability of the overall structure, reduce friction and wear between components, and at the same time, reduce looseness and vibration between components.

[0062] In addition, it is also beneficial to the overall manufacturing of the coupling, and the main body and the transmission structure 22 do not need to be manufactured separately, which effectively reduces the manufacturing cost.

[0063] That is, by configuring the main body and the transmission structure 22 as an integrated structure, a more compact, stable and reliable transmission assembly 100 is achieved. This integrated design helps to simplify the manufacturing process, reduce assembly steps, improve the work efficiency and maintainability of the entire system, and reduce manufacturing costs.

[0064] Please continue reading Figure 1 In some embodiments, the outer diameter of the half coupling 20 for connecting to the output shaft of the external power member 200 is different from the outer diameter of the half coupling 20 for driving connection with the drive shaft of the external transmission member 300.

[0065] It can be understood that by designing the outer diameters of the two half-couplings 20 differently, the two half-couplings 20 can be adapted to the requirements of connecting with different types of external devices.

[0066] Through the design of different outer diameters, the output shaft and the transmission shaft can be effectively connected to meet the specific transmission requirements of different equipment.

[0067] That is to say, in this embodiment, the transmission assembly 100 as a whole has more functions, can adapt to external devices of different types and specifications, and improve the versatility of the entire system. The selection of half-couplings 20 with different outer diameters makes the transmission system easier to customize and adjust according to specific usage scenarios.

[0068] Please continue reading Figure 1 In some embodiments, the outer diameter of the half coupling 20 for connecting to the output shaft of the external power member 200 is larger than the outer diameter of the half coupling 20 for driving connection with the transmission shaft of the external transmission member 300 .

[0069] The difference in outer diameters of the two half-couplings 20 enables the two half-couplings 20 to adapt to the connection requirements of different types of external devices.

[0070] A more stable connection can be achieved by using the half coupling 20 with a larger outer diameter, which is suitable for connection with a power device with a larger output shaft load.

[0071] Moreover, the half coupling 20 with a larger outer diameter can provide a larger transmission area, thereby improving the stability and reliability of the connection.

[0072] The half coupling 20 with a smaller outer diameter is suitable for connection with a transmission member 300 with a smaller transmission shaft, providing more flexible transmission options.

[0073] At the same time, appropriate outer diameter size difference design helps to improve transmission efficiency and reduce energy loss during transmission.

[0074] That is to say, through the arrangement of this embodiment, the transmission assembly 100 can be made more flexible and can adapt to external devices of different types and sizes, while the reliability and efficiency of the transmission connection are improved by the difference in the size of the outer diameter.

[0075] Please continue reading Figure 1 In the second aspect, the utility model also provides a driving mechanism, including a power member 200, a flexible member and the above-mentioned transmission assembly 100, the output shaft of the engine is transmission-connected to the reducer 10, and the flexible member is transmission-connected to the transmission structure 22.

[0076] The transmission assembly 100 in this embodiment can refer to the settings of the above-mentioned embodiments, and the specific structure of the transmission assembly 100 can refer to the above-mentioned embodiments. Since the driving mechanism adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0077] Please continue reading Figure 1 In some embodiments, the power member 200 is a motor or an engine, and the flexible member is a transmission belt or a transmission chain.

[0078] Specifically, the selection of the power member 200 and the flexible member are described below.

[0079] Selection of power component 200: As the driving source of the transmission system, the power component 200 can be a motor or an engine. The specific selection depends on the application needs and performance requirements.

[0080] Electric motors are typically used in scenarios that require electrical input, while engines are used for internal combustion power transmission using oil or other fuels.

[0081] Flexible parts selection: Flexible parts are components that transmit power in the transmission system. You can choose a transmission belt or a transmission chain, depending on the design and application scenario of the transmission system.

[0082] Transmission belts are suitable for flexible transmission and low noise applications, while transmission chains are usually used for transmission requirements of high torque and high efficiency.

[0083] The motor or engine is connected to the transmission system through the half coupling 20 to transmit power to the flexible member. The design of the half coupling 20 makes the connection flexible and can adapt to motors or engines of different models and specifications.

[0084] In the transmission option of the transmission belt or the transmission chain: the transmission belt or the transmission chain transmits power from the power member 200 to the external device or other parts of the transmission system through effective contact with the transmission structure 22 (such as the sprocket surface or wheel surface mentioned above).

[0085] The choice of drive belt or drive chain depends on the specific requirements of the transmission system, such as transmission efficiency, noise level, load requirements, etc.

[0086] This design allows different types of power members 200 and flexible members to be selected in the transmission system to adapt to different application scenarios and performance requirements. The combination of the motor or engine and the transmission belt or transmission chain can be optimized according to specific needs, thereby achieving a more flexible and efficient transmission system.
