Description

Technical Field

[0001] This invention relates to the field of structural testing technology, and more particularly to a testing device for a torque limiter. Background Technology

[0002] A torque limiter, also known as a safety coupling, is a component that connects a driving machine and a driven machine. Its main function is overload protection. When an overload or mechanical failure causes the required torque to exceed a set value, it limits the torque transmitted by the transmission system by slippage. Once the overload condition disappears, it automatically reconnects. Therefore, to ensure that the torque limiter can reliably and accurately perform its protective function in practical applications, it needs to undergo rigorous testing before leaving the factory. During testing, a certain load is usually applied to the torque limiter to simulate actual operating conditions, thereby evaluating its performance.

[0003] Existing torque limiter testing devices generally include a drive motor and a load application mechanism. The drive motor is connected to one end of the torque limiter to apply power, while the load application mechanism applies a certain resistance or load to the other end of the torque limiter to detect its working state under different load conditions. In existing technologies, the load application mechanism mainly applies load through pneumatic loading, hydraulic loading, etc., which can achieve rapid adjustment of the load size. However, this is only suitable for general testing scenarios and is difficult to test the overload protection capability of the torque limiter. This is because when a sudden change to hydraulic locking is required, the load should be stable above a certain range. However, in reality, due to issues such as oil compressibility, leakage, and valve vibration, there are significant fluctuations in the locking load, which leads to unstable changes in the slippage state of the torque limiter. This makes it impossible to accurately evaluate the performance of the torque limiter, especially when the torque limiter is suddenly locked.

[0004] In summary, existing torque limiter detection devices suffer from insufficient testing accuracy. Summary of the Invention

During the rotation of the transmission component, the position of the pressure component is changed, thereby changing the first gap and thus changing the loading force of the loading assembly on the transmission component, simulating the working condition of the torque limiter under different loads. Next, when it is necessary to simulate a sudden increase in load on the transmission component, the position of the pressure component is changed so that the first gap is smaller than the locking gap, increasing the loading force. At the same time, the locking component is moved to the locking position, using the locking component to limit the pressure component and prevent the pressure component from retracting, ensuring that the torque limiter enters a slipping state, which facilitates accurate evaluation of the performance of the torque limiter, thereby improving the detection accuracy of the torque limiter detection device.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0047] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] The torque limiter detection device provided in this embodiment is applied to torque limiter detection in scenarios such as vehicle power structure and mechanical equipment, especially in fields requiring overload protection detection. A torque limiter, also known as a safety coupling, is a coupling structure that limits transmission torque through a slippage mechanism under overload or mechanical failure conditions, thereby preventing system damage. In this embodiment, the detection accuracy is improved by modifying the specific structure of the torque limiter detection device.

[0050] like Figures 1 to 7 As shown, the torque limiter detection device provided in this embodiment specifically includes a frame 100, a drive assembly 200, a transmission component 300, and a loading assembly 400; a torque limiter detection station 101 is provided on the frame 100; The drive assembly 200 is located below the torque limiter detection station 101, and the rotating end of the drive assembly 200 is used to install the torque limiter. The drive assembly 200 includes, but is not limited to, structures such as servo motors, stepper motors, and rotary cylinders, and only needs to have a rotating end. This rotating end extends from bottom to top and is used to install the torque limiter (not shown in the figure). The connection between the torque limiter and the rotating end is mainly achieved through the locking structure on the torque limiter, which is not specifically limited in this embodiment. The transmission component 300 is located above the torque limiter detection station 101 and is connected to the torque limiter. The connection between the transmission component 300 and the torque limiter is achieved through the locking structure on the torque limiter, which is not specifically limited in this embodiment. The transmission component 300 includes a cylindrical part and a disc part. The cylindrical part is inserted into the torque limiter from top to bottom. The diameter of the disc part is larger than that of the cylindrical part, which facilitates the subsequent loading assembly 400 to provide load to the torque limiter through the disc part.

[0051] like Figures 1 to 3 , Figure 7As shown, the loading assembly 400 includes a pressure member 410 radially disposed on one side of the transmission member 300. The first distance between the pressure member 410 and the transmission member 300 is adjustable, and the loading force of the loading assembly 400 is inversely proportional to the first distance. It can be understood that as the pressure member 410 gets closer to the transmission member 300, the loading force continuously increases, thereby dynamically adjusting the loading force of the loading assembly 400. At the same time, the loading assembly 400 also includes a locking member 420 corresponding to the pressure member 410. The locking member 420 can move between an unlocked position and a locked position. The locked position is located on the end face of the pressure member 410 away from the transmission member 300. When the first distance is less than or equal to the locking distance, the locking member 420 is in the locked position and abuts against the pressure member 410. It should be noted that the unlocked position is when the locking component 420 and the pressure component 410 do not interfere with each other, and the loading force is only related to the position of the pressure component 410; the locked position is when the locking component 420 interferes with the position of the pressure component 410. At this time, the locking component 420 is located on the end face of the pressure component 410 away from the transmission component 300, which restricts the movement of the locking component 420 in the direction away from the transmission component 300, and also provides additional support for the pressure component 410.

[0052] Specifically, in this embodiment, the torque limiter detection device, after sequentially installing the transmission member 300 and the torque limiter on the rotating end of the drive assembly 200, drives the transmission member 300 to rotate. During the rotation of the transmission member 300, the position of the pressure member 410 is changed, thereby changing the first gap and thus changing the loading force of the loading assembly 400 on the transmission member 300, simulating the working condition of the torque limiter under different loads. Next, when it is necessary to simulate a sudden increase in load on the transmission member 300, the position of the pressure member 410 is changed so that the first gap is less than or equal to the locking gap, increasing the loading force while moving the locking member 420 to the locking position. The locking member 420 limits the pressure member 410, preventing the pressure member 410 from retracting, ensuring that the torque limiter enters a slipping state, which facilitates accurate evaluation of the torque limiter's performance and improves the detection accuracy of the torque limiter detection device.

[0053] Furthermore, such as Figures 1 to 6As shown, the loading assembly 400 includes a loading housing 430 disposed on the frame 100, which covers the torque limiter detection station 101. The loading housing 430 has a slide 431 protruding from the position corresponding to the pressure member 410, and the slide 431 has a groove 432 opened in the radial direction of the transmission member 300. The pressure member 410 includes a first abutment member 411 and a second abutment member 412. The first abutment member 411 passes through the groove 432 and is slidably connected to the groove 432. In the radial direction of the transmission member 300, the second abutment member 412 is slidably connected to the first abutment member 411, and a spring unit (not shown) is provided between the second abutment member 412 and the first abutment member 411. The second abutment member 412 abuts against the first abutment member 411 through the spring unit. The connection method between the spring unit and the abutment member includes, but is not limited to, welding and bonding.

[0054] Understandably, when the first abutment 411 is not in contact with the transmission member 300, the first abutment 411 is pushed and pulled by the second abutment 412 through the spring unit. When the first abutment 411 is in contact with the transmission member 300, the distance between the second abutment 412 and the transmission member 300 is the first distance, so that the compression of the spring unit is inversely proportional to the first distance. That is, when the first abutment 411 is in contact with the transmission member 300 and cannot move further, the second abutment 412 is pushed further in the direction closer to the transmission member 300, which will compress the spring unit, causing the elastic force of the spring unit to increase, and the pressure of the first abutment 411 on the transmission member 300 will also increase accordingly, thereby achieving precise adjustment of the loading force.

[0055] As a specific implementation, the first abutting member 411 includes an abutting portion 4111, and a friction portion is embedded at one end of the abutting portion 4111 facing the transmission member 300. The friction portion includes, but is not limited to, materials such as tungsten steel and alumina ceramic. A sliding portion 4112 is connected to the side of the abutting portion 4111 away from the transmission member 300. The sliding portion 4112 is slidably connected to the slide groove 432, and a loading space 4113 is formed in the sliding portion 4112. The second abutting member 412 is slidably connected to the sliding portion 4112. The first end 4121 of the second abutting member 412 extends through the sliding portion 4112 into the loading space 4113. The first end 4121 abuts against the abutting portion 4111 through a spring unit.

[0056] Specifically, the first abutting member 411 includes an abutting portion 4111, with a friction portion embedded at one end facing the transmitting member 300. The embedded friction portion provides a stable loading surface, ensuring the contact stability between the abutting portion 4111 and the transmitting member 300 during loading, and avoiding test errors caused by poor contact. The connection between the sliding portion 4112 and the groove 432 makes the displacement of the pressure member more precise, and the friction portion further enhances the stable transmission of loading force, enabling the simulation of more realistic load conditions. Furthermore, the spring unit within the loading space 4113 acts on the abutting portion, and the adjustment of the compression amount can adjust the loading force according to the needs of the load conditions, which greatly improves the test accuracy and the reliability of simulating load changes.

[0057] Furthermore, such as Figure 4 and Figure 7 As shown, a transmission groove 433 is provided on the groove wall of the slide groove 432, and a transmission component 440 is provided in the transmission groove 433; the output end of the transmission component 440 is connected to the locking member 420; a triggering structure 450 is provided on the first end 4121. When the first gap is less than or equal to the locking gap, the transmission component 440 is triggered by the triggering structure 450 to drive the locking member 420 to move to the locking position and abut against the end of the sliding part 4112 away from the abutting part 4111.

[0058] The slide 432 has a transmission groove 433 on its wall, and a transmission assembly 440 is installed in the transmission groove. This allows the transmission assembly 440 to be quickly triggered when the distance between the first abutment member 411 and the transmission member 300 reaches a set value, thereby moving the locking member 420 to the locking position. Through this structure, the transmission assembly 440 can precisely control the position of the locking member 420, moving it to the locking position when the first distance is less than or equal to the locking distance, thus providing additional support for the pressure member 410. Furthermore, this structure, located within the slide 431, offers advantages such as compact design and stable transmission.

[0059] In one specific implementation, the transmission assembly 440 includes a meshing transmission gear 441 and an arc-shaped toothed plate 442; the trigger structure 450 includes a rack portion disposed on the first end 4121; the transmission groove 433 includes a first connecting groove 4331 and a second connecting groove 4332 connected together; the transmission gear 441 is rotatably connected to the first connecting groove 4331, and the arc-shaped toothed plate 442 is rotatably connected to the second connecting groove 4332; the rotational connection method of the transmission gear 441 and the arc-shaped toothed plate 442 with the connecting groove is not limited, including but not limited to mounting a rotating shaft on the gear / toothed plate and rotatably connecting the rotating shaft with the connecting groove; a guide post is provided on the gear / toothed plate, and a guide groove is opened on the groove sidewall of the connecting groove; the gear / toothed plate is limited by the sliding fit between the guide post and the guide groove; the end of the arc-shaped toothed plate 442 can extend out from the second connecting groove 4332, and the end of the arc-shaped toothed plate 442 is fixedly connected to the locking member 420.

[0060] Understandably, reference Figure 7 When the first gap is less than or equal to the locking gap, that is, when the rack moves to the right, the transmission gear 441 is correspondingly engaged and driven by the rack to rotate counterclockwise; then, the transmission gear 441 drives the arc-shaped toothed plate 442 to rotate counterclockwise, causing the arc-shaped toothed plate 442 to extend from right to left, thereby driving the locking member 420 to move from the unlocked position to the locked position, just enough to allow the locking member 420 to abut against the sliding part 4112 of the first abutment member 411, specifically the left end of the sliding part 4112, to lock the position of the first abutment member 411.

[0061] Furthermore, the loading assembly 400 includes multiple pairs of pressure-applying components 410 and locking components 420, which are spaced apart around the transmission component 300. This design of multiple pairs of pressure-applying components 410 and locking components 420 spaced apart around the transmission component 300 effectively increases the uniformity and stability of the loading assembly. In this structure, the distribution of each pressure-applying component and locking component allows the loading force to act more evenly on the torque limiter, thereby achieving more accurate load simulation.

[0062] In one specific implementation, the second end 4122 of the second abutment 412, located away from the first abutment 411, is connected to a pushing column 413; a drive ring 460 is provided on the outer ring of the torque limiter detection station 101, and a pushing block 461 is provided on the drive ring 460 corresponding to each pushing column 413. The pushing block 461 is configured with a pushing surface, and the distance between the pushing surface and the frame 100 is reduced along the direction close to the transfer member 300; the pushing column 413 is slidably connected to the pushing surface; a lifting unit is provided on the frame 100, and the lifting end of the lifting unit is fixedly connected to the drive ring 460. The lifting unit includes, but is not limited to, structures such as a lifting cylinder, a lifting hydraulic cylinder, and a telescopic rod motor. The second end 4122 of the second abutment 412, located away from the first abutment 411, is connected to the pushing column 413. By combining the design of the drive ring 460 and the push block 461, when the push column and the push surface are slidably connected, the movement of the pressure component can be effectively adjusted, further enhancing the control accuracy of the loading component 400, and making the overall structure more compact and occupying less space.

[0063] As another alternative implementation, a radially arranged cylinder or hydraulic cylinder can be positioned on the side of the second abutment 412 away from the transmission member 300 to directly push the second abutment 412.

[0064] Furthermore, a collection cylinder 500 is installed on the frame 100 outside the torque limiter testing station 101. The inner wall of the collection cylinder 500 has a continuous flow channel (not shown). An observation channel 102 is provided on the frame 100, connected to the flow channel. The installation of the collection cylinder 500 and the corresponding observation channel 102 on the frame 100 effectively collects grease leaking during torque limiter operation, ensuring that grease is collected and guided to the collection area promptly and effectively, reducing the risk of grease scattering or accumulating, and avoiding contamination of the testing environment and surrounding equipment. For torque limiters used long-term, it also allows for the accumulation and accurate recording of leakage, providing fundamental data for subsequent analysis of leakage and evaluation of the equipment's long-term performance. Therefore, the observation channel 102 provides operators with a real-time view, facilitating monitoring of the condition and extent of grease leakage. Through visual observation, staff can intuitively assess grease leakage in the torque limiter under different working loads and operating conditions. Especially during long-term operational testing, the observation channel provides an effective monitoring tool, helping testers confirm the actual performance of the torque limiter under high loads and determine if there are any abnormal leaks or excessive wear. The enhanced visibility of observation channel 102 further improves the testing process while ensuring a clean testing environment, facilitating subsequent operations.

[0065] Furthermore, the observation channel 102 is positioned vertically within the gap between the two pressure members 410. A horizontal moving device 600 is also mounted on the frame 100. A vertical moving device 700 is installed at the moving end of the horizontal moving device 600, and a sensing unit is installed at the lifting end of the vertical moving device 700. The sensing unit can pass through the gap between the two pressure members 410 and partially insert into the observation channel 102. The horizontal moving device 600 and the vertical moving device 700 may include, but are not limited to, structures such as cylinders and linear motors, capable of moving the sensing unit horizontally and lifting it to insert it into the observation channel 102. The sensing unit may include, but is not limited to, oil sensing lines and liquid sensors, capable of recording the position of grease in the observation channel 102; for example, during multiple tests, the time it takes for the grease to reach a certain position in the observation channel 102 under different test conditions can be recorded. This configuration allows for flexible adjustment of the recording position, improving the flexibility of data recording.

[0066] Furthermore, a clearance groove 434 is provided on the loading housing 430 at the position corresponding to the transmission member 300, and an observation slot 435 is provided on the clearance groove 434 at the position corresponding to the lifting end of the vertical moving device 700. The clearance groove 434 on the loading housing 430 at the position corresponding to the transmission member 300 provides the necessary space for the vertical moving device 700, ensuring its smooth operation. The observation slot 435 provides a clearer view for precise observation and data acquisition. This design enhances the flexibility of the detection process and provides more possibilities for precise adjustment and monitoring.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
