Description

Technical Field

[0001] This utility model belongs to the field of bearing testing technology, and in particular relates to a performance testing mechanism for manufacturing self-lubricating low-friction bearings. Background Technology

[0002] Self-lubricating low-friction bearings are used in many mechanical devices, especially in environments where direct lubrication with oil or grease is not possible (such as high-temperature, vacuum, or corrosive environments).

[0003] According to a method for preparing high-precision self-lubricating bearings using transfer film technology (publication number: CN104279231A), a suitable self-lubricating material is selected according to different working environments, and a transfer film grinding wheel is made and applied to a grinding machine as the grinding wheel. Then, under a specific transfer film grinding wheel linear speed and grinding time, the inner spherical surface of the outer ring of the spherical bearing is ground by the transfer film grinding wheel, and a self-lubricating layer is obtained on the inner spherical surface of the outer ring of the spherical bearing.

[0004] In the aforementioned application, the interaction between components such as grinding wheels and bearings makes it difficult to solve the problem of unavoidable test errors caused by shaking, resulting in an unstable test process that needs improvement. Utility Model Content

[0005] The purpose of this invention is to provide a performance testing mechanism for manufacturing self-lubricating low-friction bearings. By detecting the interaction between components such as the clamping plate and hydraulic cylinder inside the anti-displacement assembly, repeated frictional contact between the grinding head and the bearing is achieved. This simulates the bearing's usage in a real working environment, testing its wear resistance, surface damage, and friction characteristics, thus helping to determine the bearing's service life and performance. Through the weight of the bearing itself and the precise anti-displacement assembly, the bearing can be effectively prevented from shaking during grinding. The simultaneous ejection of the clamping plate firmly clamps the bearing, reducing bearing displacement and ensuring stability during the testing process. This avoids testing errors caused by shaking and solves existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

One end of the shaped rod 41 is fixedly connected to the side of the piston rod 315. An actuating rod 42 is fixedly connected to the side of the shaped rod 41. A support rod 43 is fixedly connected to the top of the testing machine body 1. A rotating shaft 44 is rotatably connected to the top of the support rod 43.

By rotating the fan blade 46, air is blown onto the top of the placement plate 33 to remove dust from the top of the placement plate 33.

[0031] The inclined rod 47 is located on the displacement trajectory of the trigger rod 42. A torsion spring 45 is fixedly connected to the circumferential surface of the rotating shaft 44. The end of the torsion spring 45 away from the rotating shaft 44 is fixedly connected to the top of the support rod 43.

[0032] The fan blades 46 are located above the placement plate 33. Several fan blades 46 are arranged in a circumferential array on the circumferential surface of the rotating shaft 44. The top of the test machine body 1 is fixedly connected to a limit rod 34. The end of the limit rod 34 away from the test machine body 1 passes through the bottom of the placement plate 33.

[0033] A spring 314 is fixedly connected to the circumferential surface of piston rod 312. The end of spring 314 away from piston rod 312 is fixedly connected to one end of hydraulic cylinder 311. The design of spring 314 allows piston rod 312 to automatically reset when it is not compressed.

[0034] One specific application of this embodiment is as follows: In this application, by starting the motor 318, the rotation of the motor 318 drives the grinding head 319 to rotate, placing the bearing on top of the placement plate 33, and using the grinding head 319 to grind the bearing to test its wear resistance. The results of the grinding test are then displayed by a testing machine. During the test, the bearing and the grinding head 319 repeatedly come into contact and rub against each other, the amount of wear is recorded, and surface damage is monitored. To prevent the bearing from shaking during the grinding process, the bearing itself has a certain weight when placed on top of the placement plate 33. When the bearing is placed on top of the placement plate 33, it will cause the placement plate 33 to press down. The downward pressing of the placement plate 33 will cause the pressing rod 35 to move downward. The downward movement of the pressing rod 35 will press against the first triangular block 36. Due to the influence of the inclined plane, the first triangular block 36 will be pressed to the right. The rightward movement of the first triangular block 36 will cause the second triangular block 37 to move to the right. The rightward movement of the second triangular block 37 will press against the first piston rod 312. The bottom end of the first piston rod 312 is provided with a third triangular block. Due to the influence of the inclined plane of the third triangular block, the first piston rod 312 will be pressed and move to the right. As the piston rod 312 moves upward, it moves and compresses the liquid inside the hydraulic cylinder 311. This pushes the piston rod 315 at the other end of the hydraulic cylinder 311 outward. The outward movement of the piston rod 315 then pushes out the clamping plate 316. Two sets of anti-displacement components 3 are provided, located on both sides of the placement plate 33. When both clamping plates 316 are pushed out simultaneously, they clamp the bearing in the middle, reducing bearing displacement. Through repeated frictional contact between the grinding head 319 and the bearing, the bearing's usage in the actual working environment can be simulated, testing its wear resistance, surface damage, and friction characteristics. This precise test can provide true durability data of the bearing material, helping to determine the bearing's service life and performance. When the bearing is placed on the placement plate 33, its own weight and the precise anti-displacement components effectively prevent the bearing from shaking during grinding. The simultaneous push-out of the clamping plates 316 firmly clamps the bearing, reducing bearing displacement and ensuring stability during the test, avoiding test errors caused by shaking.

[0035] As described above, the piston rod 315 extends, which in turn moves the shaped rod 41 and the trigger rod 42. The movement of the trigger rod 42 compresses the inclined rod 47, causing the inclined rod 47 to rotate. The rotation of the shaft 44 then rotates the fan blade 46, which generates airflow. The fan blade 46 is located on top of the placement plate 33, and the airflow generated by the fan blade 46 blows the dust and debris generated during grinding away from the top of the placement plate 33. The design of the torsion spring 45 allows the shaft 44 to automatically reset when it is not being driven. The airflow generated by the rotating fan blade 46 effectively blows away the dust and debris generated during grinding or other operations on the top of the placement plate 33. Maintaining a clean testing environment is crucial, especially when testing self-lubricating low-friction bearings. Even small amounts of dust or debris can affect the accuracy of the test results, leading to errors in the coefficient of friction and lubrication performance. This automatic airflow cleaning system ensures the stability and accuracy of the testing environment.
