Description

Technical Field

[0001] This utility model belongs to the field of transmission belt manufacturing technology, and specifically relates to a multi-functional testing platform for transmission belts. Background Technology

[0002] In the field of transmission belt manufacturing technology, durability is a key indicator for measuring the quality and performance of transmission belts, directly affecting their reliability and service life in actual use. Accurately assessing the durability of transmission belts is of great significance for ensuring the stable operation of mechanical equipment, reducing maintenance costs, and improving production efficiency.

[0003] Currently, most existing transmission belt testing equipment on the market focuses on testing the basic parameters of the transmission belt, such as its geometric dimensions (length, width, thickness, etc.) and fundamental mechanical properties (tensile strength, modulus of elasticity, etc.). While these testing methods can reflect some characteristics of the transmission belt to a certain extent, they have significant limitations.

[0004] On the one hand, parameter testing alone cannot comprehensively and realistically simulate the complex stress conditions and operating states of transmission belts in actual working environments. In actual use, transmission belts are subject to the combined effects of various factors such as alternating loads, friction, high temperatures, and wear, and existing parameter testing methods cannot effectively reflect the impact of these dynamic factors on the durability of transmission belts.

[0005] On the other hand, the lack of simulation testing leads to a disconnect between test results and actual application scenarios. It's impossible to predict in advance the potential failure modes of the drive belt, such as fatigue and breakage, under long-term, high-load operation, making it difficult to implement targeted optimizations and improvements during the product design and manufacturing stages.

[0006] Therefore, it is urgent to develop a multi-functional testing platform that can combine simulation testing to comprehensively and realistically evaluate the durability of transmission belts, in order to meet the demand of the transmission belt manufacturing industry for high-quality testing equipment and promote the improvement of the industry's technical level. Summary of the Invention

[0019] To better understand this utility model, the embodiments of this utility model will be explained in detail below with reference to the accompanying drawings.

[0020] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0021] This utility model's multi-functional transmission belt testing platform mainly includes a platform base 1. A brake motor 2 is installed on one side of the top surface of the platform base 1. The brake motor 2 is firmly fixed to the platform base 1 by a fixing device to ensure that it will not shift during operation. A driven pulley 3 is provided on the drive shaft of the brake motor 2. Two sets of linear slide rails 4 are arranged parallel to each other on the top surface of the platform base 1, respectively installed on both sides of the drive screw 8. Each set of linear slide rails 4 includes a high-precision square rail and two square sliders. Each high-precision square rail is provided with two square sliders, which are respectively connected to a first slide block 5 and a second slide block 6. This structure allows the first slide block 5 and the second slide block 6 to slide smoothly and accurately on the linear slide rails 4, reducing friction and errors during movement and improving the accuracy of testing.

[0022] A first slide block 5 and a second slide block 6 are arranged side by side on the linear slide rail 4, and are connected by a tension sensor 7. The tension sensor 7 is an S-type tension sensor, which has the advantages of high accuracy and good stability, and can accurately measure the tension on the transmission belt during the test. Through the tension sensor 7, the stress condition of the transmission belt can be obtained in real time, providing important data for analyzing its durability.

[0023] The top surface of the platform base 1 is equipped with a drive screw 8 that drives the second slide 6 to move. The drive screw 8 is connected to a drive device via a coupling 13. The drive device can be a stepper motor or a servo motor, etc., which can precisely control the rotation of the drive screw 8, thereby achieving precise movement of the second slide 6 on the linear guide rail 4. By adjusting the position of the second slide 6, the tension of the transmission belt can be changed to simulate different operating conditions.

[0024] A drive motor 9 is mounted on the first slide 5. A drive pulley 10, corresponding to the driven pulley 3, is mounted on the drive shaft of the drive motor 9. A torque-speed sensor 11 is also mounted on the first slide 5. Furthermore, a second shaft seat 15 and a mounting base 14 for fixing the torque-speed sensor 11 are also mounted on the first slide 5. The drive shaft passes through the second shaft seat 15, and the two ends of the rotating shaft of the torque-speed sensor 11 are connected to the drive shaft and the drive shaft of the drive motor 9 via couplings 13. The torque-speed sensor 11 can measure the torque and speed of the output shaft of the drive motor 9 in real time, providing data support for analyzing the transmission performance of the transmission belt.

[0025] The top surface of the platform base 1 is provided with a first bearing seat 12, on which a driven shaft passes. The driven shaft is detachably connected to the driven pulley 3, and the other end of the driven shaft is connected to the drive shaft of the brake motor 2 through a coupling 13. At the same time, the fixed seat 14 provided on the first slide 5 is used to fix the torque and speed sensor 11 to ensure the stability of the sensor during operation.

[0026] Considering the different models and structures of various transmission belt products, such as V-belts and toothed belts, the corresponding pulley structures also differ. Therefore, the driven pulley 3 and the drive shaft are connected in a detachable manner, as are the drive pulley 10 and the drive shaft. The specific structures of the detachable connections between the drive pulley 10 and the driven pulley 3 utilize existing technology. Here, we take a common plug-in connection method as an example (not shown in the figure): One end of the drive shaft is designed with a plug-in part of a specific shape, such as a cylindrical structure with a certain taper at the end. The center of the drive pulley 10 has a matching plug-in hole, the inner wall shape and size of which fit tightly with the plug-in part of the drive shaft. During installation, the plug-in part of the drive shaft is directly inserted into the plug-in hole of the drive pulley 10. To ensure a secure connection, an interference fit can be used between the plug-in part and the plug-in hole, meaning the size of the plug-in part is slightly larger than the size of the plug-in hole. External force is used to press the drive shaft into the drive pulley 10, and torque is transmitted through the friction between the two. Meanwhile, to prevent the drive pulley 10 from loosening in the axial direction, a locking nut can be installed on the drive shaft near the drive pulley 10. The locking nut, through its threaded engagement with the drive shaft, can be tightened to press firmly against the end face of the drive pulley 10, thereby restricting its axial movement. When it is necessary to disassemble the drive pulley 10, simply loosen the locking nut and then use an appropriate tool to pull the drive shaft out of the drive pulley 10. This plug-in connection method has advantages such as convenient installation and disassembly, and good alignment, and can meet the replacement needs of drive pulleys 10 of different specifications. The detachable connection method between the drive shaft and the drive pulley is the same as the principle between the driven pulley and the driven belt pulley 3.

[0027] Considering that the diameter of the driving pulley 10 is often smaller in actual applications, the diameter of the driven pulley 3 used for testing is larger than that of the driving pulley 10.

[0028] To ensure operator safety, safety light curtains 16 are installed at both ends of the front of the platform base 1. The safety light curtains 16 can immediately send a signal when an object is detected entering the danger zone, causing the detection platform to stop operating and preventing accidents.

[0029] In addition, several adjustable feet (existing technology) are symmetrically arranged at the bottom of the platform base 1. The level of the platform base 1 can be adjusted by adjusting the feet to ensure that the entire testing platform works in a stable state and reduce measurement errors caused by unevenness of the platform.

[0030] The usage and principle of this utility model: When using this multi-functional transmission belt testing platform, first select the appropriate driven pulley 3 and driving pulley 10 according to the specifications of the transmission belt to be tested. For the driven pulley 3, install it on the driven shaft using a keyway connection. Specifically, insert a flat key into the keyway on both the driven pulley 3 and the driven shaft, and install the shaft retaining ring. For the driving pulley 10, install it on the driving shaft using a plug-in connection. Insert the plug part of the driving shaft into the plug hole of the driving pulley 10, and tighten the lock nut after an interference fit. Then, install the transmission belt to be tested between the driven pulley 3 and the driving pulley 10, adjust the belt tension, and control the drive screw 8 to rotate via the drive device, causing the second slide 6 to move until the tension displayed by the tension sensor 7 reaches the preset value.

[0031] Next, brake motor 2 and drive motor 9 are started. Brake motor 2 not only simulates the load, but its built-in braking device also plays a crucial role in the test. When it is necessary to simulate the response of the transmission belt under different load changes, brake motor 2 adjusts its output torque to change the load size. The braking device ensures that brake motor 2 stops quickly or stabilizes at a specific speed when the load changes rapidly, preventing excessive load fluctuations due to inertia, thus ensuring the accuracy and stability of the test data. Drive motor 9 provides power to start the transmission belt. During operation, torque and speed sensor 11 measures the torque and speed of the output shaft of drive motor 9 in real time, and tension sensor 7 measures the tension of the transmission belt in real time, transmitting this data to the data acquisition system.

[0032] Operators can monitor the operating parameters of the transmission belt in real time through an external data acquisition system, such as torque, speed, and tension, and analyze the belt's durability and transmission performance based on this data. Simultaneously, the safety light curtain 16 remains operational to ensure operator safety. Upon completion of the test, the brake device of the brake motor 2 immediately activates, causing it to quickly stop rotating, which in turn stops the driven pulley 3, thus rapidly halting the transmission belt's operation. The drive motor 9 is then stopped, and the tested transmission belt is removed according to the appropriate disassembly method, completing one testing cycle.

[0033] This multi-functional transmission belt testing platform can comprehensively and realistically simulate the stress and operating conditions of transmission belts in actual working environments, providing a reliable testing method for the research, development, production, and quality control of transmission belts.
