Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and bearing industry technology, and in particular to a sliding bearing friction and wear test device. Background Technology

[0002] The sliding bearing friction and wear experimental apparatus is a specialized device used to simulate the actual working environment of sliding bearings and quantitatively study the friction characteristics, wear patterns, and failure mechanisms of friction pairs such as shafts and bearing bushes. Its core function is to reproduce the bearing working scenario through controllable operating parameters (such as load, speed, and lubrication conditions) and acquire friction and wear data through a precision measurement system, providing technical support for material research and development, structural optimization, and operating condition design.

[0003] Friction and wear testing devices simulate actual friction conditions to achieve quantitative analysis of material wear behavior, providing crucial data for materials research and development, engineering design, and tribological research. They are an important tool bridging theory and practical application. Their principles are based on motion control, load application, and data monitoring, and their functions encompass multiple levels, including material performance evaluation, wear mechanism analysis, and engineering optimization. Common motions include sliding, rolling, reciprocating motion, or combined motions such as sliding plus rolling. Through motor drive or hydraulic devices, the motion speed and contact pressure are precisely controlled to simulate different working conditions.

[0004] In existing technologies, sliding bearing experiments involve different materials such as metals, ceramics, and composite materials; different structures such as radial bearings and thrust bearings; and different operating conditions such as dry friction and lubrication. Adjustable fixing devices can adapt to various experimental scenarios by changing the installation method or parameters. However, without such devices, the equipment can only be used for a single type of experiment, limiting the scope of research. For example, it is difficult to simulate wear under different load conditions by adjusting the contact area. Therefore, a sliding bearing friction and wear experimental device is proposed to solve the above problems. Utility Model Content

[0033] Multiple fixed blocks 7 have connecting plates 8 rotatably connected to their inner walls.

The inner wall of the fixing block 3 14 is rotatably connected to a cylinder 2 15, which provides stability for the cylinder 2 15, preventing shaking and displacement during operation, which would affect the operation of the subsequent components. The drive end of the cylinder 2 15 is fixedly connected to a fixing block 4 16, which moves the fixing block 4 16 when the cylinder 2 15 is in operation, providing power for the subsequent components.

[0035] Both sides of the fixed block 4 16 are fixedly connected to the transmission rods 17. When the fixed block 4 16 moves, it drives the transmission rods 17 to move, transmitting power to the subsequent components. The other end of the transmission rods 17 is fixedly connected to the fixed plate 2 18. The transmission rods 17 provide the operation of the fixed block 4 16 to drive the fixed plate 2 18 to move.

[0036] Reference Figure 1 , Figure 2 and Figure 4The inner wall of the worktable 1 is slidably connected to a slider 20. The top of the worktable 1 is provided with a groove.

The outer wall of the multiple support rods 21 is slidably connected to a bearing 22. The support rods 21 provide guidance to the bearing 22 and cooperate with the spring 23 to ensure the stability of the bearing 22 during operation.

[0037] Multiple fixed plates 11 are fixedly connected to the outer walls of sliding bushings 24. The fixed plates 11 provide the components for fixing the sliding bushings 24. The outer wall of the connecting rod 4 is rotatably connected to the inner wall of the support plate 12.

The other end of the connecting plate 8 is rotatably connected to the outer wall of the fixed plates 11. The connecting plate 8 provides the components for moving the fixed plates 11, fixing or disassembling the sliding bushings. The inner wall of the moving ring 6 is slidably connected to the outer wall of the connecting rod 4. The outer wall of the fixed plate 18 is rotatably connected to the outer wall of the fixed rod 19 to provide stability and guidance for the moving ring 6 and prevent deviation during operation.

The outer wall of the fixed plate 18 is slidably connected to the inner wall of the square box 13 to provide stability for the square box 13 and prevent shaking during operation, thus ensuring stability when fixing the slider 20.

[0038] Working principle: When the sliding bushing 24 needs to be disassembled, the cylinder 5 on the outer wall of the connecting rod 4 is activated, pushing the moving ring 6 to move linearly on the outer wall of the connecting rod 4. When the moving ring 6 moves, it drives the connecting plate 8 connected to the inner wall of the fixing block 7 to move. Through the movement of the fixing block 7, the fixing plate 11 connected to the other end moves. When the fixing plate 11 moves, it drives the fixing block 9 and the connecting plate 10 at the bottom of the connecting rod 4 to move, thus achieving the effect of disassembling the sliding bushing 24. When it needs to be fixed, the cylinder 5 retracts, driving the moving ring 6 to move. When the moving ring 6 moves, it drives the fixing block 7 to move. The connecting plate 8 rotatably connected to the inner wall of the fixing block 7 drives the fixing plate 11 to fix the sliding bushing 24. When the fixing plate 11 moves, it drives the fixing block 9 and the connecting plate 10 at the rear end of the connecting rod 4 to move, ensuring the stability of the sliding bearing 24.

[0039] When the bearing bush 22 needs to be disassembled or replaced, the cylinder 2 15 in the square box 2 13 is activated, which drives the fixed block 4 16 at the drive end to move. The fixed block 4 16 drives the transmission rods 17 at both ends to rotate. The transmission rods 17 transmit power to the fixed plate 2 18 through the fixed block 4 16. The fixed plate 2 18 rotates through the fixed rod 19. The two ends of the fixed rod 19 are fixed to the two ends of the inner wall of the square box 2 13, providing stability when the fixed plate 2 18 rotates, so as to fix and disassemble the slider 20. The support rod 21 and the spring 23 at the top of the slider 20 play a buffering and guiding role when the bearing bush 22 is subjected to friction and wear test, ensuring stability during the test.
