Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, and in particular to a power transmission device that can quickly switch the output end. Background Technology

[0002] In fields such as machinery manufacturing and automation equipment, power transmission devices are an indispensable and crucial component, used to transfer power from a power source to various working parts. In equipment that requires frequent switching of power output, such as machine tools and production lines, the switching speed and ease of operation of the power transmission device's output end directly affect work efficiency. Furthermore, in many scenarios, a single power source is needed to drive multiple output ends to save equipment space and cost.

[0003] Currently, existing power transmission devices often require shutdown and complex mechanical adjustments or component replacements when switching outputs. This switching process is time-consuming and cumbersome. Furthermore, some devices struggle to stably drive multiple outputs from a single power source, or experience unstable power transmission during switching. This not only reduces equipment efficiency but can also lead to production interruptions and economic losses in scenarios with high production continuity requirements. Therefore, developing a power transmission device capable of rapidly switching outputs and achieving one-to-many outputs is of significant practical importance.

[0004] Chinese patent document CN219911051U discloses a single-power asynchronous pump set for transporting multiple liquids, including a synchronous belt, a first synchronous pulley disposed inside the synchronous belt, and second synchronous pulleys located on both sides inside the synchronous belt. The input end of the first synchronous pulley is connected to a motor; the output end of the second synchronous pulley is connected to an electromagnetic clutch, the output end of the electromagnetic clutch is connected to a coupling, and the output end of the coupling is connected to a pump body. The motor in this invention can drive the first synchronous pulley to rotate, and the first synchronous pulley can synchronously drive several second synchronous pulleys to rotate via the synchronous belt. The second synchronous pulleys can drive the electromagnetic clutch to rotate, and the electromagnetic clutch can be engaged, thereby driving the pump body via the coupling. This allows multiple pump bodies to transport multiple liquids, and the operating state of the pump bodies can be controlled via the electromagnetic clutches, enabling synchronous transport, individual transport, or arbitrary combination transport. This solution uses an electromagnetic clutch to achieve asynchronous power transmission. However, while it can achieve multiple pump bodies transporting multiple liquids, it cannot achieve arbitrary switching between different output ends.

[0005] There is an urgent need for a power transmission technology solution that can switch quickly. Utility Model Content

[0006] In view of the technical problems existing in the prior art, the present invention aims to provide a power transmission device that can quickly switch output ends, which can overcome the problems of slow switching speed, complicated operation and difficulty in achieving stable driving of multiple output ends by one power source in the prior art.

[0007] Specifically, to achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A power transmission device capable of rapidly switching output ends is characterized by comprising a motor, a reducer, a shift fork mechanism, and a power output mechanism. The output shaft of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the shift fork mechanism. The power output mechanism includes a driving synchronous pulley, multiple driven synchronous pulleys, and a synchronous belt. The shift fork mechanism is connected to and drives the driving synchronous pulley. The multiple driven synchronous pulleys are connected by a synchronous belt, and each driven synchronous pulley drives an output end. The driving synchronous pulley can selectively engage with different driven synchronous pulleys via a synchronous belt to achieve power transmission switching.

[0009] Furthermore, the shift fork mechanism includes a shift fork body and a driving component. One end of the shift fork body is connected to the output end of the reducer, and the other end is connected to the active synchronous pulley. The driving component drives the shift fork body to move the active synchronous pulley axially, ensuring that the active synchronous pulley can accurately engage with different driven synchronous pulleys.

[0010] Furthermore, the driving component is a pneumatic cylinder or a hydraulic cylinder, which can provide a stable driving force to ensure the reliable operation of the shift fork mechanism.

[0011] Furthermore, the motor and the reducer are connected by a coupling to ensure the stability and reliability of power transmission between the motor and the reducer, and to reduce vibration and impact.

[0012] Furthermore, each of the output terminals is connected to a different working component to meet the power requirements of the different working components.

[0013] Furthermore, both the driving and driven synchronous pulleys have toothed grooves on their surfaces that are compatible with the synchronous belt, ensuring stable transmission between the synchronous belt and the synchronous pulleys and preventing slippage.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention connects a motor to a reducer, which in turn connects to a shift fork mechanism. The shift fork mechanism drives the active synchronous pulley, allowing it to selectively engage with different driven synchronous pulleys via a synchronous belt. Each driven synchronous pulley drives one output end, enabling rapid switching between multiple output ends driven by a single motor. This eliminates the need for complex mechanical adjustments or component replacements, significantly improving switching speed and ease of operation. The reducer's output speed and torque can be adjusted to better suit the requirements of the working components. The motor and reducer are connected via a coupling, ensuring stable power transmission. The active and driven synchronous pulleys are driven by a toothed synchronous belt, ensuring stable power transmission and preventing slippage. Multiple output ends connect to different working components, meeting the needs of various working scenarios, effectively improving equipment efficiency, and saving space and cost.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will understand that this description is exemplary and the present invention is not limited to the specific embodiments described herein.

[0020] Figure 1 This is a schematic diagram of the power transmission device. Figure 2 This is a schematic diagram of the synchronous pulley connection structure of a power transmission device.

[0021] like Figures 1-2As shown, the power transmission device capable of quickly switching output ends in this specific embodiment includes a motor 1, a reducer 2, a shift fork mechanism, and a power output mechanism. The output shaft of the motor 1 is connected to the input end A of the reducer 2 via a coupling 3, and the output end B of the reducer 2 is connected to the shift fork mechanism. The shift fork mechanism includes a shift fork body 4 and a driving component 5. In this embodiment, the driving component 5 is exemplified as a cylinder. One end of the shift fork body 4 is connected to the output end B of the reducer 2, and the other end is connected to the power output mechanism. In another preferred embodiment, the driving component 5 is a hydraulic cylinder, with one end of the shift fork body 4 connected to the output end B of the reducer 2 and the other end connected to the power output mechanism.

[0022] The power output mechanism includes a driving synchronous pulley 6, three driven synchronous pulleys 7, and a synchronous belt 8. The driving synchronous pulley 6 is connected to the end C of the shift fork body 4 away from the reducer 2. The three driven synchronous pulleys 7 are connected by the synchronous belt 8. Each driven synchronous pulley 7 drives an output end 9. The surfaces of the driving synchronous pulley 6 and the driven synchronous pulleys 7 are provided with tooth grooves D that are adapted to the synchronous belt 8. Each output end 9 is connected to a different working component (not shown in the figure).

[0023] During operation, motor 1 starts, and its output shaft transmits power to reducer 2 via coupling 3. Reducer 2 adjusts the speed and torque before transmitting them to the shift fork mechanism. When power needs to be transmitted to the working component connected to the first output end 9, cylinder 5 (i.e., drive component 5) drives shift fork body 4 to move drive synchronous pulley 6 axially, so that drive synchronous pulley 6 and first driven synchronous pulley 7 are connected via synchronous belt 8. Power is transmitted sequentially through motor 1, coupling 3, reducer 2, shift fork mechanism, drive synchronous pulley 6, and synchronous belt 8 to the first driven synchronous pulley 7, and then drives the corresponding working component to work through the first output end 9.

[0024] When switching to the working component connected to the second output terminal 9 is required, the cylinder drives the shift fork body 4 to move the driving synchronous pulley 6 in the opposite direction, causing the driving synchronous pulley 6 to separate from the first driven synchronous pulley 7. Then, it continues to drive the driving synchronous pulley 6 to move, causing the driving synchronous pulley 6 to engage with the second driven synchronous pulley 7 through the synchronous belt 8, thus completing the switching of the power transmission output terminal. Similarly, the power transmission switching to the working component connected to the third output terminal 9 can be realized.

[0025] The present invention has been described in detail above. However, the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will understand that various modifications and changes can be made. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention shall fall within the protection scope of the present invention. The protection scope of the present invention is defined by the appended claims.
