Abstract
Description
Technical Field
[0001] This application relates to the technical field of clutch testing devices, specifically a novel clutch life testing bench. Background Technology
[0002] As a core component of modern industrial transmission systems, the stability and reliability of pneumatic clutches directly affect the overall system's operational efficiency and safety. In practical applications, pneumatic clutches must meet stringent requirements for transmission efficiency, wear resistance, and service life to ensure smooth operation and long-term stability of the equipment.
[0003] Currently, the factory performance tests for pneumatic clutches mainly include involute spline wear testing, end face tooth wear testing, and testing of key parameters such as actuation performance. These tests aim to comprehensively evaluate the various performance indicators of the clutch to ensure that it meets the expected requirements in practical applications.
[0004] Existing testing methods and techniques often rely on complex theoretical mechanical calculations and three-dimensional simulations due to the lack of specialized clutch testing benches. This not only increases testing costs but also makes it difficult to guarantee the accuracy and reliability of test results. Furthermore, the imperfections in testing methods lead to situations where some clutches, despite passing factory tests, still exhibit unstable performance and premature wear during actual use, severely impacting equipment operating efficiency and safety.
[0005] Therefore, this application provides a novel clutch life test bench to solve the above problems. Utility Model Content
[0006] This application provides a novel clutch life test bench, which aims to solve the problems mentioned in the background art regarding existing clutch testing methods and means. Due to the lack of a dedicated clutch testing test bench, the testing process often relies on complex theoretical mechanical calculations and three-dimensional simulations, which not only increases testing costs but also makes it difficult to guarantee the accuracy and reliability of test results.
[0007] To achieve the above objectives, this application provides the following technical solution: a novel clutch life test bench, comprising a mechanical auxiliary bench, an electrical control cabinet disposed at one end of the mechanical auxiliary bench, a swing structure for driving the rotation of a pneumatic clutch, and a control structure for controlling the torque of the pneumatic clutch to remain constant.
[0008] The control structure includes a bracket fixedly mounted on the mechanical auxiliary platform, a magnetic powder controller fixedly mounted on the bracket for clutch installation, and a tension controller mounted on the electrical control cabinet and connected to the magnetic powder controller.
[0009] The swing structure includes a cylinder hinged to the mechanical auxiliary platform, a swing plate hinged to the output end of the cylinder for connection to a pneumatic clutch, sensors positioned above and below the swing plate on the mechanical auxiliary platform and connected to the electrical control cabinet for sensing the up and down positions of the swing plate, and a bearing housing mounted on the output shaft of the magnetic powder controller and connected to the mechanical auxiliary platform. During the swing test of the clutch, the pneumatic clutch is mounted on the output shaft of the magnetic powder controller and connected to the cylinder via the swing plate. Then, the bearing housing is mounted on the output shaft of the magnetic powder controller and fixed to the mechanical auxiliary platform. The electrical control cabinet sends a command to the tension controller to adjust the magnetic field strength of the magnetic powder controller, ensuring the clutch's working torque reaches a preset value and remains stable. The cylinder is activated, causing it to reciprocate, thereby driving the swing plate and clutch to swing. The sensors monitor the position of the swing plate in real time and feed the signal back to the electrical control cabinet. The electrical control cabinet, based on a preset program and the sensor signals, controls the speed and amplitude of the cylinder's movement to simulate the dynamic environment of the clutch during actual operation.
[0010] To facilitate the inspection of the end-face tooth separation condition and wear of the pneumatic clutch, a drive component is installed on the mechanical auxiliary platform to drive the axial movement of the pneumatic clutch. The addition of this drive component enables rapid and accurate inspection of the end-face tooth separation condition and wear of the pneumatic clutch, significantly improving inspection efficiency. The drive component can simulate the engagement and disengagement process of the pneumatic clutch in actual operation, making the inspection results closer to reality and improving the accuracy and reliability of the inspection.
[0011] Preferably, to facilitate cylinder installation: a T-shaped seat is fixedly mounted on the mechanical auxiliary platform, and a U-shaped seat that snaps onto the T-shaped seat is fixedly connected to the end of the cylinder near the mechanical auxiliary platform. The U-shaped seat and the T-shaped seat are hinged together by a pin. The design of the T-shaped seat and the U-shaped seat makes the cylinder installation process simpler and faster, greatly improving installation efficiency.
[0012] Preferably, to prevent collisions between the cylinder and the mechanical auxiliary platform during the rotation of the cylinder driving the swing plate, buffer pads are fixedly connected to all four corners of the end of the cylinder closest to the mechanical auxiliary platform. The buffer pads are made of highly elastic, wear-resistant materials, such as rubber or silicone. These materials have excellent shock absorption and wear resistance, effectively absorbing the impact force generated during cylinder rotation and protecting the cylinder and mechanical auxiliary platform from damage.
[0013] Preferably, to facilitate sensor installation, an L-shaped support plate for sensor mounting is bolted to the mechanical auxiliary platform. The L-shaped support plate design simplifies and speeds up sensor installation, eliminating the need for complex positioning and fixing steps and significantly improving installation efficiency.
[0014] Preferably, the drive unit includes a solenoid valve connected to the output end of a pressure source and an air pipe fixedly mounted on a pneumatic clutch and connected to the solenoid valve, wherein the solenoid valve is connected to the electrical control cabinet.
[0015] This application utilizes a magnetic powder brake and a tension controller to maintain a constant operating torque during clutch testing. The oscillating structure simulates the dynamic environment of a clutch in actual operation, including oscillation angle and frequency, making the test results closer to reality. The drive component simulates the engagement and disengagement process of a pneumatic clutch in actual operation, further improving the accuracy and reliability of the test results. The experimental platform design automates and intelligently enhances the testing process, reducing manual intervention and errors, thereby lowering testing costs. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] This embodiment provides a novel clutch life testing bench, such as Figure 1-5 As shown, the experimental platform includes a mechanical auxiliary platform 1, an electrical control cabinet 2 located at one end of the mechanical auxiliary platform 1, a swing structure 3 for driving the pneumatic clutch to rotate, and a control structure 5 for controlling the pneumatic clutch torque to remain constant.
[0025] The control structure 5 includes a bracket 51 fixedly mounted on the mechanical auxiliary platform 1, a magnetic particle controller 52 fixedly mounted on the bracket 51 for clutch installation, and a tension controller 53 mounted on the electrical control cabinet 2 and connected to the magnetic particle controller 52. Through the cooperation of the magnetic particle controller 52 and the tension controller 53, precise control of the clutch's working torque can be achieved, thereby improving the accuracy and reliability of the test. The working torque of the clutch remains constant during the test when controlled by the magnetic particle brake and the tension controller 53. Specifically, the magnetic particle brake is an FZ-50 with a working torque range of 0-500 N·m, and the tension controller is a KTC800A.
[0026] The swing structure 3 includes a cylinder 31 hinged to the mechanical auxiliary platform 1, a swing plate 32 hinged to the output end of the cylinder 31 for connection to the pneumatic clutch, a sensor 33 located on the mechanical auxiliary platform 1 corresponding to the upper and lower parts of the swing plate 32 and connected to the electrical control cabinet 2 for sensing the vertical position of the swing plate 32, and a bearing seat 34 mounted on the output shaft of the magnetic powder controller 52 and connected to the mechanical auxiliary platform 1. The swing structure 3 can simulate the dynamic environment of the clutch in actual operation, including swing angle and frequency, making the test results closer to the actual situation. The design of the experimental platform makes the testing process more automated and intelligent, reducing manual intervention and errors, thereby reducing testing costs. When performing a swing test on the clutch, the pneumatic clutch is mounted on the output shaft of the magnetic powder controller 52 and connected to the cylinder 31 through the swing plate 32. Then, the bearing seat 34 is mounted on the output shaft of the magnetic powder controller 52 and fixed to the mechanical auxiliary platform 1. The electrical control cabinet 2 sends a command to the tension controller 53 to adjust the magnetic field strength of the magnetic powder controller 52 so that the working torque of the clutch reaches the preset value and remains stable. The cylinder 31 is activated to reciprocate, thereby causing the swing plate 32 and the clutch to swing. The sensor 33 monitors the position of the swing plate 32 in real time and feeds the signal back to the electrical control cabinet 2. The electrical control cabinet 2 controls the speed and amplitude of the cylinder 31 according to the preset program and the signal from the sensor 33 to simulate the dynamic environment of the clutch in actual operation.
[0027] To facilitate the inspection of the end face tooth separation condition and wear of the pneumatic clutch, a drive component 4 is installed on the mechanical auxiliary table 1 to drive the axial movement of the pneumatic clutch. The drive component 4 includes a solenoid valve 41 connected to the output end of a pressure source and an air pipe 42 fixedly mounted on the pneumatic clutch and connected to the solenoid valve 41. The solenoid valve 41 is connected to the electrical control cabinet 2. The addition of the drive component 4 enables rapid and accurate inspection of the end face tooth separation condition and wear of the pneumatic clutch, greatly improving inspection efficiency. The drive component 4 can simulate the engagement and disengagement process of the pneumatic clutch in actual operation, making the inspection results closer to the actual situation and improving the accuracy and reliability of the inspection. Through automated and intelligent inspection methods, manual intervention and errors are reduced, lowering inspection costs. When inspecting the end face tooth separation condition and wear of the pneumatic clutch, the pneumatic clutch must first be installed on the output shaft of the magnetic powder controller 52 and connected to the cylinder 31 via the swing structure 3. Then, the air pipe 42 of the drive component 4 is connected to the pneumatic clutch, ensuring that the solenoid valve 41 is correctly connected to the electrical control cabinet 2. At the start of the test, the electrical control cabinet 2 sends a command to the solenoid valve 41 to control the frequency of air supply switching on and off. As the air supply switches on and off, the pneumatic clutch moves axially under the action of the drive component 4, simulating its engagement and disengagement process in actual operation. Simultaneously, the sensor 33 monitors the position of the swing plate 32 and the clutch's motion status in real time, feeding back signals to the electrical control cabinet 2. The electrical control cabinet 2 adjusts the control of the solenoid valve 41 according to the preset program and the signals from the sensor 33 to ensure the stability and accuracy of the clutch during the test. During the test, key data such as the clutch's end face tooth separation condition, wear, and motion trajectory can be observed and recorded. By comparing the test results under different conditions, the clutch's performance and quality can be evaluated, providing a basis for subsequent design and improvement.
[0028] Specifically, to facilitate the installation of cylinder 31: a T-shaped seat 311 is fixedly installed on the mechanical auxiliary platform 1, and a U-shaped seat 312, which is snapped onto the T-shaped seat 311, is fixedly connected to the end of cylinder 31 near the mechanical auxiliary platform 1. The U-shaped seat 312 and the T-shaped seat 311 are hinged together by a pin. The design of the T-shaped seat 311 and the U-shaped seat 312 makes the installation process of cylinder 31 simpler and faster, greatly improving installation efficiency. During the installation of cylinder 31, first, the T-shaped seat 311 is fixed on the mechanical auxiliary platform 1, ensuring its accurate and stable position. Then, cylinder 31 is snapped onto the T-shaped seat 311 via the U-shaped seat 312 and hinged together using a pin.
[0029] To prevent collisions between the cylinder 31 and the mechanical auxiliary platform 1 during the rotation of the swing plate 32, buffer pads 6 are fixedly connected to each of the four corners of the end of the cylinder 31 closest to the mechanical auxiliary platform 1. The buffer pads 6 are made of highly elastic, wear-resistant materials such as rubber or silicone. These materials have excellent shock absorption and wear resistance, effectively absorbing the impact force generated by the cylinder 31 during rotation and protecting both the cylinder 31 and the mechanical auxiliary platform 1 from damage.
[0030] Specifically, to facilitate the installation of sensor 33, an L-shaped support plate 331 for fixing sensor 33 is bolted to the mechanical auxiliary platform 1. The design of the L-shaped support plate 331 makes the installation process of sensor 33 simpler and faster, eliminating the need for complicated positioning and fixing steps, and greatly improving installation efficiency.
