Description

Technical Field

[0002] With the development of modern industrial equipment towards higher speeds and heavier loads, high-speed heavy-duty bearings are increasingly widely used in key fields such as machinery manufacturing, aerospace, and energy transmission. Their sealing performance directly affects the bearing's service life, operational reliability, and overall equipment performance. Especially under complex operating conditions such as high speeds, heavy loads, and dusty or humid environments, seal failure can lead to bearing lubrication failure, impurity intrusion, and consequently, equipment malfunctions or even safety accidents. The high-speed heavy-duty bearing sealing performance test bench simulates actual operating conditions to test and evaluate the sealing effect, wear resistance, and stability of the bearing sealing structure under high-speed rotation and heavy load conditions. This provides crucial data support for bearing design optimization, manufacturing process improvement, and quality control, ensuring stable operation of bearings in harsh environments and meeting the high-performance and high-reliability requirements of high-end equipment for core components.

During the testing process, the bearing is easily subject to external forces, causing positional shifts or attitude changes. This makes it difficult for the testing equipment to accurately capture the true parameters of the bearing, thus affecting the accuracy and reliability of the measurement data. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a high-speed heavy-duty bearing sealing performance testing bench device, including a U-shaped base 1, a column 2 fixedly connected to the upper surface of the U-shaped base 1, a movable plate 3 slidably connected to the outer wall of the column 2, a top plate 4 fixedly connected to the top of the column 2, a cylinder 5 fixedly connected to the upper surface of the top plate 4, the output end of the cylinder 5 slidably connected to the inside of the top plate 4 and fixedly connected to the upper surface of the movable plate 3, a detection chamber seat 7 fixedly connected to the lower surface of the movable plate 3, an air pipe connector 8 provided on the outer wall of the detection chamber seat 7, a bottom sealing seat 6 fixedly connected to the upper surface of the U-shaped base 1, a fixing block 9 fixedly connected to the upper surface of the U-shaped base 1, a fixing block 10 fixedly connected to the upper surface of the U-shaped base 1, a motor 11 fixedly connected to the outer wall of the fixing block 10, the output end of the motor 11 rotatably connected to the inside of the fixing block 10 and fixedly connected to a disc 12, and a fixing component provided on the outer wall of the fixing block 9.

[0026] Specifically, when testing the bearing, the bearing is placed above the bottom sealing seat 6. Then, the cylinder 5 is activated to cause the movable plate 3 to move the test chamber seat 7 downward to perform an airtightness test on the bearing placed on the bottom sealing seat 6. The bottom sealing seat 6 is used to seal the bottom of the bearing, and the test chamber seat 7 is used to contact the upper side of the bearing and form a closed space to achieve airtightness testing. The fixing block 10 is used to support the motor 11. The motor 11 is used to rotate the disc 12 when it is started. The air pipe connector 8 is used to connect the airtightness testing equipment through the air pipe.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The fixing component includes a guide rod 13, the outer wall of the guide rod 13 is fixedly connected to the outer wall of the fixing block 9, the outer wall of the guide rod 13 is slidably connected to a moving block 14, the outer wall of the moving block 14 is fixedly connected to a clamping block 15, the outer wall of the moving block 14 is rotatably connected to a pull rod 16, and the outer wall of the pull rod 16 is rotatably connected to the end of the disc 12 away from the fixing block 10.

[0028] Specifically, the guide rod 13 guides the movement of the moving block 14, ensuring that the moving block 14 always moves horizontally along a straight line during the movement. The pull rod 16 connects the moving block 14 and the disk 12, and converts the rotational motion of the disk 12 into the horizontal movement of the moving block 14.

[0029] Reference Figure 3 and Figure 5 A stop block 17 is fixedly connected to the inner wall of the U-shaped base 1, and a slide rail 18 is fixedly connected to the outer wall of the stop block 17. A sliding block 19 is slidably connected to the outer wall of the slide rail 18, and a rack 20 is fixedly connected to the outer wall of the sliding block 19. A gear 21 is meshed with the tooth end of the rack 20, and a rotating column 22 is fixedly connected to the inner wall of the gear 21. The outer wall of the rotating column 22 is rotatably connected to the inside of the U-shaped base 1. A cylinder 25 is fixedly connected to the inner wall of the U-shaped base 1, and a connecting block 26 is fixedly connected to the output end of the cylinder 25. The outer wall of the connecting block 26 is fixedly connected to the outer wall of the sliding block 19. A sliding rod 23 is fixedly connected to the outer wall of the sliding block 19, and the outer wall of the sliding rod 23 is slidably connected to the inside of the stop block 17. A side support 24 is fixedly connected to the outer wall of the sliding rod 23, and the outer wall of the side support 24 is slidably connected to the inner wall of the U-shaped base 1.

[0030] Specifically, the abutment 17 is used to support the slide rail 18, and the slide rail 18 is used to limit and guide the sliding block 19, which can restrict the movement direction of the sliding block 19 and improve the smoothness of the sliding block 19 during movement. The second cylinder 25 is used to move the sliding block 19 through the connecting block 26. When the second cylinder 25 is started, the second cylinder 25 drives the connecting block 26 to move, and the moving connecting block 26 pushes the sliding block 19 to move and slide on the outer wall of the slide rail 18. The rack 20 is used to rotate the gear 21, thereby causing the rack 20 on the other side to move outward synchronously.

[0031] Working principle: When testing the bearing, the bearing is placed above the bottom sealing seat 6, and then the motor 11 is started. The start of the motor 11 causes the disc 12 to rotate. The rotation of the disc 12 causes the pull rod 16 to rotate at the end of the disc 12 away from the fixed block 10, and at the same time rotates on the outer wall of the moving block 14. During the process of the pull rod 16 rotating on the outer wall of the moving block 14, the pull rod 16 will pull the moving block 14 to move inward and slide on the outer wall of the guide rod 13. At the same time, it will drive the clamping block 15 to move inward to fix the bearing during the testing process. This ensures that the bearing maintains a fixed position and posture during the testing process, avoids displacement caused by external force or its own rotation, and enables the testing equipment to accurately measure various parameters of the bearing, thereby improving the accuracy and reliability of the test data.

[0032] During use, cylinder 25 is activated. Cylinder 25 causes connecting block 26 to move outward, which in turn moves sliding block 19 outward, sliding against the outer wall of slide rail 18. As sliding block 19 moves outward, it drives rack 20 to move. The movement of rack 20 causes gear 21 to rotate, which in turn causes rotating column 22 to rotate inside U-shaped base 1. The rotation of gear 21 causes rack 20 on the other side to move outward synchronously. As sliding block 19 moves outward, it drives sliding rod 23 to move outward, sliding against block 17. The outward movement of sliding rod 23 causes side support 24 to move outward, sliding against the inner wall of U-shaped base 1. The outward movement of side support 24 expands the support area of ​​U-shaped base 1, reducing displacement and swaying caused by vibration, ensuring the stability of the test process, and improving the accuracy of the test results.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
