Description

Technical Field

[0001] The utility model relates to the technical field of transmission test machines, in particular to a reconfigurable transmission test machine. Background Art

[0002] Traditional testing machines usually adopt a fixed structure design to ensure overall stability and precision. This design makes the various parts tightly integrated and difficult to decompose into independent modules. During the design and manufacturing process, it is necessary to ensure the precise alignment and firm connection of each part, so once the construction is completed, any changes or adjustments will affect the overall performance and stability of the equipment. In addition, the components of traditional testing machines are usually fixed by welding or specific mechanical connections. This connection method is difficult to achieve rapid disassembly and reassembly, and requires professionals and special tools for disassembly and maintenance, which increases the complexity and cost of operation and maintenance. Due to the single design goal, the interface design of traditional testing machines does not take into account standardization and universality. The interfaces between the various parts are often dedicated. The lack of standardized interfaces means that different modules are difficult to interchange and compatible, which limits the flexibility and scalability of the equipment. Utility Model Content

[0022] The above solution overcomes the aforementioned technical difficulties of existing experimental machines and achieves significant innovation through modular design, the use of standardized interfaces, and flexible module combinations. First, the modular design divides the experimental machine into independent components: a base module, a transmission module, a drive module, a tensioning module, and a loading module. Each module is designed with standardized interfaces, enabling independent production, testing, and replacement. This design not only maintains the overall performance and stability of the equipment but also enables independent development and improvement of each component, enhancing the equipment's flexibility and adaptability. Second, the use of standardized screws and nuts as connectors allows for quick assembly and disassembly, as well as interchangeability, simplifying the equipment's installation and maintenance. The use of standardized interfaces not only simplifies the operational process but also reduces reliance on specialized tools and specialized personnel, thereby reducing maintenance costs and complexity. Finally, the modules can be flexibly combined to meet specific experimental requirements. For example, different types of transmission modules (such as belt drive, chain drive, and gear drive) can be replaced to accommodate diverse experimental conditions and teaching objectives. This flexible modular combination not only enhances the diversity and applicability of the experimental machine but also provides a wider range of experimental options for teaching and research, greatly enhancing the educational value of the equipment.

[0038] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a reconfigurable transmission test machine, including a base module 1; providing a stable basic structure to facilitate the installation and reconfiguration of a transmission module, a drive module and a loading module;

[0039] Transmission module: includes a driving pulley 5 and a driven pulley 6, with a flat belt 7 installed between the driving pulley 5 and the driven pulley 6. The main experimental test part simulates a simple transmission system in actual engineering machinery. The driving pulley 5 and the driven pulley 6 work together to achieve power transmission and conversion. By monitoring the torque and angle data of this part, students can understand the transmission system in the machine in a digital way.

[0040] The drive module includes a first profile frame 12, a motor 13 fixed to the first profile frame 12, a third coupling 14, and a first torque sensor 15. The motor 13 transmits power to the first torque sensor 15 through the third coupling 14, and then transmits power to the driving shaft 2 through the sensor. The first torque sensor 15 of this module can measure the input torque of the entire machine, providing the driving force of the entire testing machine.

[0041] The tensioning module includes symmetrical second profile frames 16 and a tensioning pulley 17 mounted between the two second profile frames 16. This module is used to adjust the tension of the flat belt 7, ensuring the stability and efficiency of the transmission system. Adjusting the position of the tensioning pulley 17 changes the tension of the flat belt 7 to adapt to different operating conditions, preventing the flat belt 7 from slipping or loosening, and ensuring the normal operation of the transmission system.

[0042] Loading module: includes the third profile frame 18 and the brake 19, the fourth coupling 20 and the second torque sensor installed on the third profile frame 18; simulates the external load in actual engineering machinery. The brake 19 is connected to the second torque sensor 21 through the fourth coupling 20, and then transmitted to the driven shaft 3 through the sensor to simulate the working state under different load conditions

[0043] The driving module and the loading module are connected and installed on the same side of the base module 1, and the tensioning module is installed on the base module 1; the modules are connected by T-nuts and screws.

[0044] The transmission module is mounted on the base module 1. The driving shaft 2 and the driven shaft 3 are supported by bearings mounted on bearing seats 4 and bolted to the base module 1. The drive module and the loading module are mounted on the same side of the base module 1. The motor 13 and the brake 19 are connected to the torque sensor via couplings, respectively. The torque sensor is then connected to the driving shaft 2 and the driven shaft 3. The transmission module transmits power through the driving pulley 5 and the driven pulley 6, as well as the flat belt 7. Encoders are installed at the far ends of the driving shaft 2 and the driven shaft 3 to monitor the shaft speed and position in real time. The tensioning module adjusts the tension of the flat belt 7 to ensure the stability and efficiency of the transmission system. The motor 13 in the drive module provides the driving force, which is transmitted to the driving shaft 2 through the coupling and torque sensor, driving the transmission module. The brake 19 in the loading module provides the load, which is transmitted to the driven shaft 3 through the coupling and torque sensor to simulate operating conditions under different load conditions. Sensors and data acquisition systems monitor various parameters in the transmission process in real time, and analyze and display data through a cloud-based measurement and control system to help students understand the working principles and performance characteristics of the transmission system.

[0045] like Figures 3 to 6 As shown, the transmission module also includes a plurality of bearing seats 4 fixed to the base module 1 by bolts, and the driving pulley 5 and the driven pulley 6 are respectively fixed with the driving shaft 2 and the driven shaft 3, and both ends of the driving shaft 2 and the driven shaft 3 are rotatably installed in the bearing seat 4, and the first encoder 8 and the second encoder 9 are respectively installed at one end of the driving shaft 2 and the driven shaft 3 away from the driving module and the loading module, and the first coupling 10 and the second coupling 11 are respectively installed at the other end of the driving shaft 2 and the driven shaft 3.

[0046] One end of the third coupling 14 is mounted on the motor 13, and the other end of the third coupling 14 is connected to the first torque sensor 15. The first torque sensor 15 is fixed to the first profile frame 12 by bolts. The first profile frame 12 is mounted on the side of the base module 1 by an angle bracket. The second profile frame 16 is mounted on the base module 1 by an angle bracket. The tensioning pulley 17 is connected to the second profile frame 16 by bolts.

[0047] The brake is mounted on the third profile frame 18 through tooling parts, and the brake 19 is connected to the fourth coupling 20. One end of the second torque sensor 21 is connected to the fourth coupling, and the other end of the second torque sensor 21 is connected to the second coupling 11 on the driven shaft 3. The second torque sensor 21 is fixed to the third profile frame 18 by bolts, and the third profile frame 18 is mounted on the side of the base module 1 through an angle bracket.

[0048] The working principle of the technical solution provided by the utility model is as follows:

[0049] Before starting the experiment, students need to adjust the tension of the tensioning wheel 17 and the braking torque of the brake 19 according to the requirements of the experimental instructions. This step is to simulate different working environments and ensure the breadth of data and the applicability of the experiment.

[0050] Start the testing machine: After checking that all connections are secure and correct, start motor 13 in the drive module. Once started, motor 13 transmits power to drive shaft 2 via the torque sensor, rotating drive pulley 5. Drive pulley 5 drives flat belt 7, which in turn drives the driven pulley. The driven pulley, in turn, rotates driven shaft 3 via a key, applying work to brake 19, simulating the external load of the construction machine.

[0051] Data Acquisition: During the experiment, sensors monitor key parameters such as the speed and torque of the driving and driven shafts 2 and 3 in real time and transmit this data to the data acquisition system. This data is crucial for analyzing transmission efficiency and system performance.

[0052] Monitoring and Adjustment: Through the cloud-based measurement and control system (publication number CN116755900A), students can observe experimental data in real time and download the collected data. Based on the data feedback, students can adjust the experimental settings (such as changing the load or adjusting the tension). Students can also replace different types of pulleys or drive belts to explore the impact of different variables on system performance.

[0053] End of experiment and data analysis: After the experiment is complete, shut down all equipment and systematically collect and analyze the experimental data. Students will use this data to perform data analysis and evaluate the performance of the transmission system.

[0054] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
