Technical Field
[0001] The invention relates to the technical field of bearing testing, in particular to a wind power bearing forging testing machine. Background Art
[0002] In recent years, the wind turbine market has developed rapidly, bringing about the development of the wind turbine main bearing industry. During the research and development process of wind turbine main bearings, it is necessary to test products of different types and specifications, and record their axial and radial loads, temperature rise, stress strain, speed torque and other parameters to provide a basis for theoretical calculation, reliability design and fatigue life prediction. At present, wind turbine bearings are the core components of wind turbines. With the development of science and technology, the demand for wind turbine bearings is also increasing day by day. The variable pitch bearings of wind turbines connect the hub and blades, so that the blades and the hub rotate relative to each other to achieve variable pitch. If the stiffness of the variable pitch bearing does not meet the standard after production, it will cause the variable pitch bearing to deform when operating under wind load. Excessive deformation will affect the safe operation of the bearing. In order to ensure the stable quality of the wind turbine variable pitch bearing during installation and use, the stiffness of the variable pitch bearing needs to be tested before leaving the factory. Wind turbine variable pitch bearing testing machines are now mostly used for testing.
[0003] In the prior art, a Chinese patent document with patent number CN116698409A proposes a wind turbine main shaft bearing tester, comprising a mounting assembly; a fixing assembly mounted on the mounting assembly; a wind turbine main shaft bearing body mounted on the outside of the fixing assembly; a total of four support assemblies, and the four support assemblies are mounted inside the fixing assembly; a pushing assembly is mounted on the fixing assembly; a test assembly is mounted on the mounting assembly; a fixing pin is inserted into a fixing bottom plate; a mounting rod is fixedly mounted on the top of the fixing bottom plate; when the staff pulls the test handle downward, the test plate drives the anti-slip pad B to move, and at this time the wind turbine main shaft bearing body is on the anti-slip pad B. The sliding pad B rotates under the action of the sliding pad B, which is convenient for the staff to test the main body of the wind turbine main shaft bearing; it solves the problem that most of the wind turbine main shaft bearings are tested by motors, and the wind turbine main shaft bearings are not tested quickly by manual methods. However, in the actual operation of the bearings, the wind force exerts pressure on the bearings from all directions. The test only exerts pressure on one side, and it cannot accurately simulate the pressure of the variable pitch bearing under the action of wind load during normal operation. At the same time, when testing the bearings, unqualified bearings may vibrate and cause the test machine to deviate, causing the test machine and the bearing to collide, causing damage to the test machine. Therefore, the present application discloses a wind turbine bearing forging test machine to meet the requirements of improving the accuracy and stability of wind turbine bearing forging detection experiments.

[0014] Preferably, both sides of the positioning plate are rotatably connected with a deflection rod, one end of the deflection rod is rotatably connected in a connecting seat, and the connecting seat is fixedly connected to the top of the extension plate.
[0015] Compared with the prior art, the present invention provides a wind turbine bearing forging testing machine, which has the following beneficial effects:
[0016] 1. When testing the wind turbine bearing forgings, the wind turbine bearing forging testing machine makes one end of the wind turbine bearing forging to be tested contact with the guide cone. The guide cone is a conical structure that opens to one side, so that the wind turbine bearing forging can contact with the limit rod under the guidance of the guide cone. After the wind turbine bearing forging to be tested contacts with the limit rod, it continues to move to one side along the axis of the driving rod. When the wind turbine bearing forging to be tested moves to the corresponding position, the limit rod is an arc structure that opens to one side and gradually lowers and bends, and the limit rod is made of elastic material, thereby achieving fixed limit of the wind turbine bearing forging to be tested, thereby improving the efficiency of fixing the wind turbine bearing forging during testing.
[0017] 2. When the wind turbine bearing forging tester needs to perform pressure test on the wind turbine bearing forging, the driving rod is moved by connecting the steel cable, so that the rotating ring rotates on the rotating wheel, and the driving rod drives the connecting arm to deflect to one side around the axis of the pressure rod. At the same time, when the pressure rod rotates, it can synchronously drive the synchronous disk to rotate. When the synchronous disk rotates, the lifting disk is synchronously rotated under the drive of multiple sets of sliding rods, and the lifting rod fixedly connected to the bottom of the lifting disk rotates simultaneously with the rotation of the lifting disk. Under normal conditions, the lifting cylinder is under the action of gravity, so that the limit column is located at the top of the guide groove on the lifting cylinder. When the lifting rod rotates, The limit column rotates along the guide groove on the lifting cylinder, and then the lifting cylinder moves up and down along the axis of the lifting rod under the guidance of the guide groove. As the lifting cylinder moves downward, the positioning plate is driven to move synchronously with the lifting cylinder. When the positioning plate moves downward, the lifting rod drives the clamping plate to approach the wind turbine bearing forging. Therefore, the greater the distance the lifting rod drives the clamping plate to move, the smaller the diameter of the wind turbine bearing forging. Therefore, when the lifting rod drives the clamping plate to contact the wind turbine bearing forging, the extension plate at one end of the deflection rod is separated from the clamping plate, thereby adapting to wind turbine bearing forgings of different sizes and effectively improving the scope of use.
[0018] 3. The wind turbine bearing forging testing machine can form a complete circle between multiple sets of clamping plates, thereby realizing the simultaneous application of pressure in multiple directions when testing wind turbine bearing forgings. When the size of the wind turbine bearing forging is large, the extension plate is moved in the clamping plate so that the contact block at the bottom of the extension plate is in close contact with the wind turbine bearing forging, thereby ensuring that the pressure at each position during the wind turbine bearing forging test is the same, further improving the accuracy and reliability of wind turbine bearing forging testing.
[0019] 4. The wind turbine bearing forging testing machine, when testing the wind turbine bearing forgings, the sizes of the wind turbine bearing forgings are different, and the test pressure required for the test is also different. By rotating the driving rod, the connecting rod is driven to rotate around the axis of the rotating rod, so that the limit plate enters the limit groove provided on the inner wall of the guide plate. Under the guidance of the guide rod, the limit plate and the limit groove are tightly fitted by the elastic force of the limit spring. At the same time, through the multiple groups of positioning blocks fixedly connected in the limit groove, the height of the positioning block in the limit groove gradually increases to one side, so that when the rotation of the driving rod is stopped, the driving rod can still maintain the current posture, thereby ensuring the stability of the pressure during the test of the wind turbine bearing forging, and by adjusting the position of the limit plate in the guide plate, the pressure on the wind turbine bearing forging can be changed, and the operation is more convenient.
[0020] 5. When the rotating rod of the wind turbine bearing forging tester rotates, it can drive the collection plate to rotate synchronously, so that the connecting steel cable can adjust the pressure component under the conversion of the pulley group, further improving the stability of the pressure during the inspection of wind turbine bearing forgings.
[0021] 6. When the wind turbine bearing forging testing machine is testing the wind turbine bearing forging, if the wind turbine bearing forging rotates eccentrically due to its own defects, it will collide with the clamping plate and the extension plate. When the clamping plate and the extension plate are hit by the eccentric rotation of the wind turbine bearing forging, the lifting rod drives the lifting plate to move. At the same time, under the elastic force of the reset spring, the impact strength caused by the eccentric rotation of the wind turbine bearing forging can be effectively reduced, thereby buying time for stopping the detection of the wind turbine bearing forging, avoiding damage to the wind turbine bearing forging testing machine due to the long-term eccentric rotation of the wind turbine bearing forging, further improving the safety during use, and at the same time increasing the service life of the wind turbine bearing forging testing machine.

[0038] As a preferred implementation in this embodiment, refer to the attached Figure 1The pressure assembly includes a positioning cylinder 25 fixedly connected to one end of the moving plate 6, and a plurality of supporting plates 26 are fixedly connected to the surface of the positioning cylinder 25. A rotating wheel 27 is rotatably connected to one side of the supporting plate 26, and a rotating ring 28 is rotatably connected to the rotating wheel 27. A driving rod 29 is fixedly connected to one end of the rotating ring 28. A connecting arm 30 is sleeved on the driving rod 29, and a pressure rod 31 is rotatably connected to one end of the connecting arm 30. A synchronous disk 32 is fixedly connected to one end of the synchronous disk 32. A sliding rod 35 is fixedly connected to one end of the sliding rod 35. One end of the sliding rod 35 passes through a lifting disk 36. One end of the sliding rod 35 is fixedly connected to a limited position head. A lifting rod 38 is fixedly connected to the bottom of the lifting disk 36. The bottom of the rod 38 is rotatably connected to multiple groups of clamping plates 39, and the clamping plates 39 are of a semicircular structure. A group of limit columns 43 are fixedly connected to the lifting rod 38, and one end of the limit column 43 is slidably connected in the guide groove. The guide groove is provided on the lifting cylinder 37, and a positioning plate 41 is fixedly connected to the bottom of the lifting cylinder 37. Extension plates 40 are slidably connected in both sides of the clamping plate 39, and a contact block 44 is fixedly connected to the bottom of the extension plate 40. The contact block 44 is consistent with the bottom height of the clamping plate 39, and a deflection rod 42 is rotatably connected to both sides of the positioning plate 41. One end of the deflection rod 42 is rotatably connected in the connecting seat, and the connecting seat is fixedly connected to the top of the extension plate 40; when it is necessary to perform pressure testing on the wind power bearing forgings, The driving rod 29 is driven to move by the connecting steel cable 12, so that the rotating ring 28 rotates on the rotating wheel 27, and the driving rod 29 drives the connecting arm 30 to deflect to one side around the axis of the pressure rod 31.

Under normal conditions, the lifting cylinder 37 is under the action of gravity, so that the limiting column 43 is located at the top of the guide groove on the lifting cylinder 37. When the lifting rod 38 rotates, the limiting column 43 moves along the lifting cylinder 37.

One end of the limit plate 21 contacts a guide plate 22. The guide plate 22 is an arc deflected to one side. The guide plate 22 is fixedly connected to one side of the fixed frame 1. The guide plate 22 is an arc bent to one side. A limit groove 23 is provided on the inner wall of the guide plate 22. A plurality of positioning blocks 24 are fixedly connected in the limit groove 23. The height of the limit groove 23 is suitable for the limit plate 21. The connecting block 18 is in contact with the positioning block 24, and the height of the positioning block 24 gradually increases to one side in the limiting groove 23. When the wind turbine bearing forgings are tested, the sizes of the wind turbine bearing forgings are different, and the test pressures required for the test are also different. By rotating the driving rod 16, the connecting rod 17 is driven to rotate around the axis of the rotating rod 14, so that the limiting plate 21 enters the limiting groove 23 provided on the inner wall of the guide plate 22. The limiting plate 21 is closely fitted with the limiting groove 23 through the elastic force of the limiting spring 20 under the guidance of the guide rod 19. At the same time, through the multiple groups of positioning blocks 24 fixedly connected in the limiting groove 23, the limiting plate 21 is fixed. The height of the positioning block 24 gradually increases toward one side in the limiting groove 23, so that when the rotation of the driving rod 16 is stopped, the driving rod 16 can still maintain the current posture, ensuring the stability of the pressure during the test of the wind turbine bearing forgings, and by adjusting the position of the limiting plate 21 in the guide plate 22, the pressure on the wind turbine bearing forgings can be changed, and the operation is more convenient; at the same time, when the rotating rod 14 rotates, it can drive the collecting plate 15 to rotate synchronously, and then the connecting steel cable 12 can realize the adjustment of the pressure component under the conversion of the pulley group 11, further improving the stability of the pressure during the inspection of the wind turbine bearing forgings.
