Description

Technical Field

[0001] This application relates to the field of tapered roller loading technology, and in particular to a tapered roller loading device. Background Technology

[0002] Tapered rollers are key components widely used in the field of mechanical transmission. Due to their unique tapered surface structure, they can withstand axial and radial loads simultaneously and play an important role in the bearing systems of equipment such as automobiles, machine tools, and wind turbines.

[0003] In the prior art, when loading tapered rollers, radial offset or axial movement is prone to occur during the loading process. Furthermore, the tapered rollers cannot be rotated during the loading process, making it difficult to guarantee the accuracy and reliability of the test data and affecting the comprehensive evaluation of the tapered roller performance. Utility Model Content

[0004] The purpose of this application is to provide a tapered roller loading device that can effectively prevent radial offset or axial movement of the tapered roller during loading, and ensure the stability of the loading posture.

[0005] In a first aspect, this utility model provides a tapered roller loading device, comprising:

[0006] The housing has an internal cavity suitable for placing a tapered roller. A through hole is provided on the side wall of the housing, which communicates with the placement cavity.

[0007] A first pad is disposed at the bottom of the placement cavity, and the upper surface of the first pad is provided with a first inclined surface, which is adapted to abut against the bottom of the tapered roller.

[0008] The second pad is disposed at the top of the placement cavity and is disposed opposite to the first pad. The second pad is provided with a second inclined surface, which is adapted to abut against the top of the tapered roller.

[0009] The rotating component has a driving end and a connecting end. The driving end is located outside the housing, and the connecting end passes through the through hole into the placement cavity for connection with the tapered roller.

[0010] Beneficial effects: This tapered roller loading device first places the tapered roller into the placement cavity, clamping it between the first and second pads. This ensures that the first inclined surface of the first pad is in contact with the bottom of the tapered roller, and the second inclined surface of the second pad is in close contact with the top of the tapered roller. Then, the connecting end of the rotating component is inserted into the placement cavity through the through hole to connect with the tapered roller. Finally, pressure is applied to the second pad using external equipment, causing the load to be transferred step by step, thus initiating the loading test.

[0011] The first inclined surface of the first pad abuts against the bottom of the tapered roller, and the second inclined surface of the second pad abuts against the top of the tapered roller. The first and second inclined surfaces form stable support and limit for the tapered roller, which can effectively prevent radial displacement or axial movement of the tapered roller during loading and ensure the stability of the loading posture.

[0012] Meanwhile, during the loading process of the tapered roller, an external force is applied to the driving end of the rotating component, causing the rotating component to rotate, which in turn drives the tapered roller to rotate synchronously. This simulates the rotational condition of the tapered roller in actual operation, making the test more closely resemble its real-world application scenario. This helps to comprehensively evaluate the performance of the tapered roller under dynamic stress, and the test results can more realistically and comprehensively reflect the key performance of the tapered roller, such as its load-bearing capacity, providing a reliable basis for its performance evaluation.

[0013] In one optional embodiment, limiting portions are provided at both ends of the first inclined surface, and the limiting portions are respectively provided corresponding to the two ends of the tapered roller, and the limiting portions are used to abut against the ends of the tapered roller.

[0014] Beneficial effects: Based on the first inclined surface conforming to the tapered surface of the tapered roller, the axial movement of the tapered roller is further restricted by the contact between the limiting part and the end of the tapered roller. Especially during loading or rotation, it can effectively counteract the displacement tendency caused by axial force and ensure that the tapered roller is in the preset test position.

[0015] In addition, the corresponding contact between the limiting part and the end of the roller can help calibrate the placement posture of the tapered roller on the first inclined surface, avoid the tapered roller surface not fitting tightly with the first inclined surface due to installation deviation, ensure that the load force is transmitted along the preset direction, and reduce the deviation of test data.

[0016] In one optional embodiment, the tapered roller loading device further includes a limiting member disposed between the first pad and the second pad, the limiting member having a limiting hole, the limiting member covering the tapered roller so that at least a portion of the tapered roller passes through the limiting hole.

[0017] Beneficial effects: When the limiting member is placed on the tapered roller, the limiting hole and the outer circumferential surface of the tapered roller are matched and fitted, which can form a circumferential constraint on the tapered roller from the radial direction. With the axial support of the first inclined surface and the second inclined surface, it can effectively prevent the roller from radially shifting due to uneven force during loading or rotation. In particular, it can limit the swaying of the tapered roller when rotating in the circumferential direction and ensure that the tapered roller always moves stably along the preset axis.

[0018] In one alternative embodiment, the connecting end is adapted to pass through the center hole of the tapered roller and connect with the hole wall of the center hole of the tapered roller.

[0019] Beneficial effects: The direct connection between the connecting end and the wall of the center hole of the tapered roller ensures that their axes are completely aligned, avoiding radial runout caused by eccentricity during transmission. This is crucial for simulating the actual rotational state of tapered rollers during operation, ensuring stable transmission of parameters such as applied force and torque along the preset axis and improving the accuracy of test data.

[0020] In one optional embodiment, the tapered roller loading device further includes a first pressure plate and a second pressure plate. The first pressure plate is disposed at the bottom of the first pad, and the upper surface of the first pressure plate is in contact with the bottom surface of the first pad. The second pressure plate is disposed at the top of the second pad, and the lower surface of the second pressure plate is in contact with the top surface of the second pad.

[0021] Beneficial effects: The first pressure plate adheres to the bottom of the first pad, and the second pressure plate adheres to the top of the second pad, effectively limiting warping, deformation, or displacement of the first and second pads during loading. For the first pad, the first pressure plate provides upward support from the bottom, counteracting the downward bending tendency caused by the pressure of the tapered rollers; for the second pad, the second pressure plate applies constraint from the top, preventing the second pad from arching or shifting upwards during loading. The cooperation of the first and second pressure plates ensures that the first and second pads always maintain a preset tilt angle and flatness, providing a stable support reference for the tapered rollers.

[0022] In one alternative embodiment, the upper surface of the second pressure plate protrudes beyond the upper surface of the housing.

[0023] Beneficial effects: In tapered roller loading tests, it is usually necessary to apply the load to the second pressure plate through an external loading device, which then transfers the load to the second pad and the tapered roller. Since the upper surface of the second pressure plate protrudes from the housing, it can be directly exposed to the outside of the housing, providing a clear point of force application for the external loading mechanism and ensuring that the external loading device can directly apply the load to the second pressure plate.

[0024] In one optional embodiment, the tapered roller loading device further includes a first filling plate and a second filling plate, wherein the first filling plate is embedded between the first pad and the housing;

[0025] The second filling plate is embedded between the second pad and the box body.

[0026] Beneficial effects: By setting the first and second filler plates, it is easy to disassemble and install the first pressure plate, second pressure plate, first pad, and second pad inside the cavity. Before installing the tapered rollers, the remaining components can be easily removed from the cavity by removing the first and second filler plates, freeing up sufficient operating space for inserting the tapered rollers and simplifying the loading process.

[0027] In one alternative embodiment, the second filler plate has a bonding surface that is bonded to the sidewall of the second pad, and a lubricating layer is provided on the bonding surface.

[0028] Beneficial effects: In tapered roller loading tests, the second pad may experience slight relative sliding or rotation with the second filler plate due to minute changes in the loading force. By applying a lubricating layer to the mating surfaces, the friction coefficient between the two contact surfaces can be significantly reduced, resulting in smoother relative movement and preventing jamming caused by excessive friction.

[0029] In one alternative embodiment, the tapered roller loading device further includes a support plate disposed between the first filling plate and the second filling plate.

[0030] Beneficial effects: During the loading process, the first and second filling plates may be displaced or slide due to force. By placing the support plate between the first and second filling plates, the support plate supports the first and second filling plates, ensuring that the first and second filling plates always maintain the preset relative position.

[0031] In one alternative embodiment, the placement cavity is adapted to hold a plurality of tapered rollers.

[0032] Beneficial effects: During the loading process of tapered rollers, multiple tapered rollers can be placed in the placement cavity at the same time, and the loading test of multiple tapered rollers can be completed at one time, which greatly shortens the overall test cycle.

[0052] In related technologies, when loading tapered rollers, radial offset or axial movement is prone to occur during the loading process. Furthermore, the tapered rollers cannot be rotated during the loading process, making it difficult to guarantee the accuracy and reliability of the test data and affecting the comprehensive evaluation of the tapered roller performance.

[0053] During the development of this application, the team first conducted fundamental research to address the core issue of tapered rollers easily shifting during loading tests. The initial technical solution focused on solving the shifting problem through structural restraint: placing the tapered rollers directly in the placement cavity within the housing, while simultaneously configuring dedicated restraint components. The tight fit between these components and the outer circumference of the tapered rollers creates radial constraints, thereby preventing radial shifting or axial movement during loading. In practice, this solution effectively stabilizes the attitude of the tapered rollers under static loading conditions.

[0054] However, as research and development progressed, the team discovered significant limitations in this solution: Because the contact between the limiting component and the tapered roller is a rigid fit, when simulating the actual rotational conditions of the tapered roller (such as the rolling state of a bearing), the limiting component generates intense friction with the tapered roller surface. This not only hinders the normal rotation of the roller but may also damage the surface precision of the roller due to frictional wear, leading to distorted test data. Furthermore, if the tapered roller is forcibly driven to rotate, the friction between the limiting component and the tapered roller generates additional torque, interfering with the accurate transmission of the loading force and making dynamic loading tests impossible. Therefore, the design relying solely on the limiting component is only suitable for static loading scenarios and cannot meet the evaluation requirements for the dynamic stress performance of tapered rollers (such as wear resistance and fatigue life under rotation), making it difficult to comprehensively reflect their actual working performance.

[0055] Based on this, the inventors of this application have redesigned the tapered roller loading device. First, the tapered roller is placed in the placement cavity, so that the tapered roller is sandwiched between the first pad and the second pad, ensuring that the first inclined surface of the first pad abuts against the bottom of the tapered roller, and the second inclined surface of the second pad fits tightly against the top of the tapered roller. Then, the connecting end of the rotating component is inserted into the placement cavity through the through hole to complete the connection with the tapered roller. Finally, pressure is applied to the second pad by external equipment to transfer the load step by step, thereby starting the loading test.

[0056] The first inclined surface of the first pad abuts against the bottom of the tapered roller, and the second inclined surface of the second pad abuts against the top of the tapered roller. The first and second inclined surfaces form stable support and limit for the tapered roller, which can effectively prevent radial displacement or axial movement of the tapered roller during loading and ensure the stability of the loading posture.

[0057] Meanwhile, during the loading process of the tapered roller, an external force is applied to the driving end of the rotating component, causing the rotating component to rotate, which in turn drives the tapered roller to rotate synchronously. This simulates the rotational condition of the tapered roller in actual operation, making the test more closely resemble its real-world application scenario. This helps to comprehensively evaluate the performance of the tapered roller under dynamic stress, and the test results can more realistically and comprehensively reflect the key performance of the tapered roller, such as its load-bearing capacity, providing a reliable basis for its performance evaluation.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, but not all embodiments.

[0059] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0060] According to embodiments of the present invention, on the one hand, such as Figures 1 to 6 As shown, a tapered roller loading device is provided, including a housing 100, a first pad 300, a second pad 400, and a rotating component 500.

[0061] Specifically, such as Figure 1 and Figure 2 As shown, the housing 100 has a placement cavity 110 for placing the tapered roller 200. A through hole 120 is provided on the side wall of the housing 100, and the through hole 120 is connected to the placement cavity 110.

[0062] Specifically, such as Figures 1 to 3 As shown, the first pad 300 is disposed at the bottom of the placement cavity 110, wherein the upper surface of the first pad 300 is provided with a first inclined surface 310, and the first inclined surface 310 abuts against the bottom of the tapered roller 200.

[0063] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the second pad 400 is disposed on the top of the cavity 110, and the second pad 400 is disposed opposite to the first pad 300. The second pad 400 is provided with a second inclined surface 410, and the tapered roller 200 is disposed between the first pad 300 and the second pad 400, with the second inclined surface 410 abutting against the top of the tapered roller 200.

[0064] Specifically, such as Figure 2 and Figure 6 As shown, the rotating component 500 has a driving end 510 and a connecting end 520. The driving end 510 is located outside the housing 100, and the connecting end 520 passes through the through hole 120 into the placement cavity 110 and connects with the tapered roller 200.

[0065] This tapered roller loading device first places the tapered roller 200 into the placement cavity 110, clamping the tapered roller 200 between the first pad 300 and the second pad 400, ensuring that the first inclined surface 310 of the first pad 300 abuts against the bottom of the tapered roller 200, and the second inclined surface 410 of the second pad 400 is in close contact with the top of the tapered roller 200; then, the connecting end 520 of the rotating component 500 is inserted into the placement cavity 110 through the through hole 120 to complete the connection with the tapered roller 200; finally, pressure is applied to the second pad 400 by external equipment to transfer the load step by step, thereby starting the loading test.

[0066] The tapered roller 200 is supported and limited by the first inclined surface 310 of the first pad 300 abutting against the bottom of the tapered roller 200 and the second inclined surface 410 of the second pad 400 abutting against the top of the tapered roller 200. The first inclined surface 310 and the second inclined surface 410 form stable support and limit for the tapered roller 200, which can effectively prevent the tapered roller 200 from radially deviating or axially moving during loading, and ensure the stability of the loading posture.

[0067] Meanwhile, during the loading process of the tapered roller 200, an external force is applied to the drive end 510 of the rotating component 500, causing the rotating component 500 to rotate, which in turn drives the tapered roller 200 to rotate synchronously. This simulates the rotational condition of the tapered roller 200 during actual operation, making the test more closely resemble its real-world application scenario. This helps to comprehensively evaluate the performance of the tapered roller 200 under dynamic stress, enabling the test results to more realistically and comprehensively reflect the key performance characteristics of the tapered roller 200, such as its load-bearing capacity, and providing a reliable basis for its performance evaluation.

[0068] Specifically, the structural design of the through hole 120 and the placement cavity 110 can be adapted to the device function and the testing requirements of the tapered roller 200. In this embodiment, no specific restrictions are placed on the structure of the through hole 120 and the placement cavity 110.

[0069] For example, the through hole 120 can be set to any existing shape such as a circular hole or a square hole. Taking a circular hole as an example, the inner diameter of the through hole 120 is slightly larger than the outer diameter of the connecting end 520 of the rotating part 500, so as to ensure that the rotating part 500 can be smoothly inserted and rotated flexibly.

[0070] Specifically, the placement cavity 110 can be a cylindrical cavity that runs vertically through the body. The inner diameter of the placement cavity 110 needs to be larger than the maximum outer diameter of the tapered roller 200 to reserve sufficient space for the small deformations of the tapered roller 200 during placement, rotation and loading, and to avoid interference between the cavity wall and the tapered roller 200.

[0071] Specifically, the inclination angles of the first inclined surface 310 and the second inclined surface 410 can be matched with the cone angle of the tapered roller 200 to ensure that the first inclined surface 310, the second inclined surface 410 and the surface of the tapered roller 200 form a close surface contact, avoiding local stress concentration or unstable support due to angular deviation.

[0072] Specifically, the driving end 510 of the rotating component 500 can be connected to an external device to drive the rotating component 500 to rotate, or it can be driven manually. In this embodiment, no specific restrictions are placed on the driving method of the rotating component 500.

[0073] In one embodiment, such as Figure 2 and Figure 3 As shown, a limiting part 320 is provided on the first inclined surface 310. The limiting part 320 is provided at both ends of the first inclined surface 310. When the tapered roller 200 is provided on the first inclined surface 310, the limiting part 320 is respectively provided corresponding to the two ends of the tapered roller 200. The limiting part 320 is used to abut against the end of the tapered roller 200.

[0074] Based on the first inclined surface 310 adhering to the conical surface of the tapered roller 200, the axial movement of the tapered roller 200 is further restricted by the contact between the limiting part 320 and the end of the tapered roller 200. Especially during loading or rotation, it can effectively counteract the displacement trend caused by axial force and ensure that the tapered roller 200 is in the preset test position.

[0075] In addition, the corresponding contact between the limiting part 320 and the end of the tapered roller 200 can help calibrate the placement posture of the tapered roller 200 on the first inclined surface 310, avoid the tapered surface of the tapered roller 200 not fitting tightly with the first inclined surface 310 due to installation deviation, ensure that the load force is transmitted along the preset direction, and reduce the deviation of test data.

[0076] Specifically, the limiting part 320 can be a flange-type limiting structure, a stop-type limiting part 320, a stepped limiting part 320, etc. In this embodiment, the structure of the limiting part 320 is not specifically limited.

[0077] For example, flanges that protrude in a direction perpendicular to the inclined surface are integrally formed or fixedly connected to the two ends of the first inclined surface 310, and the inner sidewall of the flange is parallel to the end side of the tapered roller 200.

[0078] In one embodiment, such as Figure 2 and Figure 5As shown, the tapered roller loading device also includes a limiting member 600, wherein the limiting member 600 is installed between the first pad 300 and the second pad 400, and a limiting hole 610 is provided on the limiting member 600. When the limiting member 600 covers the tapered roller 200, the top of the tapered roller 200 at least partially passes through the limiting hole 610.

[0079] When the limiting member 600 is placed on the tapered roller 200, the limiting hole 610 and the outer peripheral surface of the tapered roller 200 are fitted together, which can form a circumferential constraint on the tapered roller 200 from the radial direction. With the axial support of the first inclined surface 310 and the second inclined surface 410, it can effectively prevent the tapered roller 200 from radially shifting due to uneven force during loading or rotation. In particular, it can limit the swaying of the tapered roller 200 during circumferential rotation, ensuring that the tapered roller 200 always moves stably along the preset axis.

[0080] In addition, the limiting hole 610 can accurately position the tapered roller 200, avoid the skewing that occurs during manual placement, ensure the fitting accuracy of the tapered roller 200 with the first inclined surface 310 and the second inclined surface 410, and reduce the problem of uneven load transmission caused by initial posture deviation.

[0081] Specifically, by replacing the limiting component 600 with different bore diameters, the testing requirements of tapered rollers 200 with different diameters can be adapted, improving the versatility of the device; at the same time, the edge of the limiting hole 610 can be rounded to avoid rigid friction with the outer peripheral surface of the tapered roller 200, reducing wear on the surface of the tapered roller 200.

[0082] In one embodiment, such as Figure 2 As shown, the connecting end 520 of the rotating member 500 is adapted to pass into the central hole of the tapered roller 200 and connect with the hole wall of the central hole of the tapered roller 200.

[0083] The connecting end 520 is directly connected to the wall of the center hole of the tapered roller 200, ensuring that their axes are completely aligned and avoiding radial runout caused by eccentricity during transmission. This is crucial for simulating the actual rotational state of the tapered roller 200 during operation, ensuring that parameters such as applied force and torque are stably transmitted along the preset axis, and improving the accuracy of test data.

[0084] Specifically, the connecting end 520 of the rotating component 500 can be connected to the wall of the central hole through interference fit, key connection or spline connection, etc. In this embodiment, no specific restrictions are placed on the connection method between the connecting end 520 and the hole wall.

[0085] Specifically, when the connecting end 520 is connected to the tapered roller 200 through the center hole, the center hole itself can serve as a natural positioning reference, and the installation and alignment can be quickly completed without additional adjustment of the circumferential or axial position of the tapered roller 200.

[0086] In one embodiment, such as Figure 2 As shown, the tapered roller loading device further includes a first pressure plate 700 and a second pressure plate 800. The first pressure plate 700 is disposed at the bottom of the first pad 300, and its upper surface is in contact with the bottom surface of the first pad 300. The second pressure plate 800 is disposed at the top of the second pad 400, and its lower surface is in contact with the top surface of the second pad 400.

[0087] The first pressure plate 700 adheres to the bottom of the first pad 300, and the second pressure plate 800 adheres to the top of the second pad 400. This effectively limits the warping, deformation, or displacement of the first pad 300 and the second pad 400 during loading due to forces (such as radial force and axial force transmitted by the tapered rollers 200). For the first pad 300, the first pressure plate 700 provides upward support from the bottom, counteracting the downward bending tendency of the first pad 300 caused by the pressure of the tapered rollers 200. For the second pad 400, the second pressure plate 800 applies constraint from the top, preventing the second pad 400 from arching upwards or shifting during loading. The cooperation of the first pressure plate 700 and the second pressure plate 800 ensures that the first pad 300 and the second pad 400 always maintain a preset tilt angle and flatness, providing a stable support reference for the tapered rollers 200.

[0088] In one embodiment, such as Figure 1 and Figure 2 As shown, the upper surface of the second pressure plate 800 protrudes from the upper surface of the housing 100.

[0089] In the tapered roller 200 loading test, an external loading device (such as a hydraulic cylinder, servo motor, or weight loading device) is typically used to apply a load to the second pressure plate 800, which then transmits the load to the second pad 400 and the tapered roller 200. Since the upper surface of the second pressure plate 800 protrudes from the housing 100, it is directly exposed to the outside of the housing 100, providing a clear point of force application for the external loading mechanism and ensuring that the external loading device can directly apply a load to the second pressure plate 800.

[0090] The protruding design of the second pressure plate 800 can avoid spatial interference between the top of the box 100 and the loading mechanism, which is especially suitable for large-volume loading equipment and ensures that the loading force can be stably transmitted along the preset direction.

[0091] Specifically, if the second pressure plate 800 is flush with or lower than the upper surface of the housing 100, the external loading force may first act on the housing 100 and then be indirectly transmitted to the second pressure plate 800, which may easily lead to load loss due to deformation of the housing 100 or contact gap.

[0092] In one embodiment, such as Figure 2 As shown, the tapered roller loading device also includes a first filling plate 900 and a second filling plate 1000, wherein the first filling plate 900 is embedded between the first pad 300 and the housing 100, and the second filling plate 1000 is embedded between the second pad 400 and the housing 100.

[0093] By setting the first filler plate 900 and the second filler plate 1000, it is easy to disassemble and install the first pressure plate 700, the second pressure plate 800, the first pad 300, and the second pad 400 inside the placement cavity 110. Before inserting the tapered roller 200, the remaining components can be easily removed from the placement cavity 110 by removing the first filler plate 900 and the second filler plate 1000, freeing up sufficient operating space for inserting the tapered roller 200 and simplifying the loading process.

[0094] After the tapered roller 200 is installed, the first filler plate 900 can accurately fill the gap between the first pad 300 and the housing 100, and the second filler plate 1000 can fill the gap between the second pad 400 and the housing 100, thereby installing the pad, pressure plate and other components in the preset position, avoiding displacement or shaking caused by loose components during loading test, and ensuring structural stability and test accuracy.

[0095] In one embodiment, such as Figure 2 As shown, the second filler plate 1000 has a bonding surface 1100, wherein the bonding surface 1100 is bonded to the side wall of the second pad 400, and a lubricating layer is provided on the bonding surface 1100.

[0096] During the tapered roller 200 loading test, the second pad 400 may experience slight relative sliding or rotation with the second filler plate 1000 due to minute changes in the loading force (such as dynamic load or angle adjustment). By providing a lubricating layer on the mating surface 1100, the lubricating layer can significantly reduce the coefficient of friction between the two contact surfaces, making the relative movement smoother and avoiding jamming caused by excessive friction.

[0097] Furthermore, when there is frictional resistance between the second pad 400 and the second filler plate 1000, the uneven friction during loading may cause a slight deviation in the direction of force transmission, affecting the accuracy of the test data. The lubrication layer can make the contact surface more uniformly stressed, reduce the load transmission error caused by friction fluctuations, and ensure that the loading force acts stably on the tapered roller 200 along the preset path.

[0098] Specifically, a lubricating layer can be formed by coating the bonding surface 1100 with lubricating oil or graphite, or a lubricating coating can be directly applied to the bonding surface 1100. In this embodiment, the type of lubricating layer is not specifically limited.

[0099] In one embodiment, such as Figure 2 As shown, the tapered roller loading device also includes a support plate 2000, which is installed between the first filling plate 900 and the second filling plate 1000.

[0100] During the loading process, the first filling plate 900 and the second filling plate 1000 may be displaced or slide due to force. By placing the support plate 2000 between the first filling plate 900 and the second filling plate 1000, the support plate 2000 supports the first filling plate 900 and the second filling plate 1000, ensuring that the first filling plate 900 and the second filling plate 1000 always maintain the preset relative position.

[0101] In one embodiment, the cavity 110 is adapted to accommodate a plurality of tapered rollers 200.

[0102] During the loading process of tapered roller 200, multiple tapered rollers 200 can be placed in the placement cavity 110 at the same time, and the loading test of multiple tapered rollers 200 can be completed at one time (such as simultaneously testing the load-bearing capacity, contact fatigue performance, etc. of the same batch of tapered rollers 200), which greatly shortens the overall test cycle.

[0103] The terms "upper" and "lower" are used to describe the relative positions of the various structures in the accompanying drawings. They are only for clarity of description and are not intended to limit the scope of implementation of this application. Any changes or adjustments to the relative positions without substantially altering the technical content shall also be considered within the scope of implementation of this application.

[0104] It should be noted that, in this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0105] Furthermore, in this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0106] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
