Description

Technical Field

[0001] This application relates to the field of bearing testing technology, specifically to an inner ring testing device for vertical wind turbine bearings. Background Technology

[0002] With the rapid development of the wind power industry, wind turbine bearings, as one of the key transmission components of the wind turbine main shaft system, directly affect the stability, safety, and service life of the entire machine through their manufacturing precision and testing level. Among these components, the inner ring of the wind turbine bearing, as a core load-bearing component, requires high geometric precision, excellent form and position tolerance control, and stable surface quality. Especially in large-scale wind power equipment, the measurement accuracy requirements for parameters such as the roundness, runout, and coaxiality of the inner ring are increasingly stringent.

[0003] Traditional methods for inspecting the inner rings of wind turbine bearings generally suffer from drawbacks such as simple structure, poor adaptability, and low automation. These methods cannot achieve rapid switching and efficient inspection of various bearing models, thus limiting quality control capabilities during wind turbine bearing manufacturing. Because wind turbine bearing inner ring diameters range widely, manual micrometer inspection is inefficient and prone to human error. Furthermore, the workpieces are often placed horizontally during inspection, and due to their large size, they occupy a significant amount of space, which is inconvenient for mass production and factory space.

[0018] 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 only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-3 This application provides a technical solution: an inner ring detection device for a vertical wind turbine bearing, including a base plate 7, on which an inner ring placement seat is slidably disposed.

[0020] The inner ring mounting seat is mounted on the bracket plate 8 on the linear guide rail 6. Its position can be freely adjusted to facilitate the testing of various types of bearings.

[0021] Furthermore, linear slide rails 6 are provided on both sides of the base plate 7, and a support plate 8 is provided on the linear slide rails 6, with an inner ring placement seat provided on the support plate 8.

[0022] Among them, the linear guide 6 adopts a heavy-duty roller linear guide and is equipped with a self-lubricating slider to extend its service life. The support plate 8 is made of QT600 ductile iron and is subjected to aging treatment to eliminate internal stress. It is also equipped with positioning and mounting holes to facilitate the positioning and installation of the inner ring placement seat.

[0023] A vertical support column 3 is provided in the middle of the base plate 7. Support mounting plates 2 are provided at the upper and lower ends of the vertical support column 3. A screw mechanism 1 is provided between the support mounting plates 2. The movable end of the screw mechanism 1 is connected to a bracket connecting seat 14. The bracket connecting seat 14 is connected to an intermediate mounting seat 12 by fasteners.

[0024] The vertical support column 3 and the support mounting plate 2 form the vertical frame of the device, supporting the lead screw mechanism 1 and the guide shaft 5, ensuring the rigidity and vertical movement accuracy of the detection mechanism. The upper and lower ends of both are fixed with high-strength bolts, with a reserved space in the middle for installing the lead screw mechanism 1 and the guide shaft 5. The lead screw mechanism 1 is a precision ball screw, and the guide shaft 5 is chrome-plated to reduce friction. Through the movement of the lead screw mechanism 1, the bracket connecting seat 14 located on its lead screw moves up and down, thereby adjusting the detection position to accommodate inner rings of different diameters.

[0025] The intermediate mounting base 12 is provided with a drive mechanism 13 inside. The output end of the drive mechanism 13 is provided with a detection base 15. The detection base 15 has a concave structure and a telescopic rod 10 is provided between it. An intermediate sleeve 9 is provided between the telescopic rods 10. A guide plate is provided on the intermediate sleeve 9. A striker probe 11 is provided at the end of the telescopic rod 10.

[0026] The drive mechanism 13 is driven by a servo electric cylinder with a rated thrust of 2000N and a repeatability of ±0.005mm. It adopts a three-point flange installation to eliminate installation stress and is equipped with shock-absorbing pads to reduce vibration transmission. The concave structure of the detection base 15 facilitates the installation of the intermediate sleeve 9 and the telescopic rod 10. The telescopic rod 10 can adjust its own length to adjust the position of the striker probe 11 and complete the inner ring detection. At the same time, the telescopic rod 10 also has a self-locking function to fix the position of the striker probe 11.

[0027] Furthermore, a guide shaft 5 is provided between the support mounting plates 2, and the guide shaft 5 passes through the bracket connecting seat 14.

[0028] There are two guide shafts 5, which are symmetrically arranged on the lower surface of the support mounting plate 2 to guide and ensure the stability of the bracket connecting seat 14 during movement.

[0029] Furthermore, the intermediate mounting base 12 is a concave structure, which is connected to the bracket connecting base 14 by fasteners, and the cavity of its concave structure is used to install the drive mechanism 13.

[0030] Furthermore, the inner ring placement seat is provided with an arc-shaped groove 4 for placing the workpiece.

[0031] The arc groove 4 adopts an involute curved surface design, which is suitable for diameters ranging from 50 to 5000 mm. The inner ring contact surface is a replaceable polyurethane gasket to prevent scratches when scraped.

[0032] Furthermore, the inner ring mounting base is provided with an anti-tipping support shaft.

[0033] The anti-tipping support is linearly set on the inner ring placement seat. The workpiece to be tested is located between the anti-tipping support and the arc groove 4. The anti-tipping support and the arc groove 4 form a support to prevent the workpiece from tipping over and improve the convenience of use.

[0034] Furthermore, the impact pin probe 11 is a detachable structure, with a highly wear-resistant probe head at its end and a spring reset structure.

[0035] Furthermore, the intermediate sleeve 9 is provided with a positioning pin for positioning the telescopic rod 10, and the positioning pin is provided on the intermediate sleeve 9.

[0036] In use: Place the inner ring of the wind turbine bearing to be tested on the inner ring placement seat, which is slidably mounted on the linear slide rails 6 on both sides of the base plate 7 via the bracket plate 8. The operator can freely slide the bracket plate 8 according to the size of the workpiece to be tested, aligning the center of the inner ring with the central axis of the testing mechanism. Adjust the length of the anti-tipping support shaft to position it on the side of the inner ring of the wind turbine bearing to prevent the workpiece from tipping or shifting during testing, thus improving testing safety and stability. Start the lead screw mechanism 1, driving the bracket connecting seat 14 to move up and down. Precisely adjust the height of the testing base 15 to move it to the center position of the inner ring to be tested. At this time, adjust the length of the telescopic rod 10 so that the striker probe 11 can contact the inner wall of the inner ring of the wind turbine bearing to be tested. The telescopic rod 10 is in a self-locking state. Ensure that the striker probe 11 does not move. The drive mechanism 13 drives the testing base 15 to rotate slowly, and the telescopic rod 10 pushes the striker probe 11 to contact various points on the inner wall of the workpiece in sequence, achieving continuous scanning and testing of multiple key parameters such as roundness, runout, and coaxiality.
