Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine bearing testing technology, and in particular to a wind turbine bearing testing device. Background Technology
[0002] Wind turbine bearings are core components of wind turbine generators. Due to their harsh working environment, complex loads, and difficult maintenance, they require highly reliable testing devices.
[0003] When inspecting the dimensions of wind turbine bearing rings, a depth gauge is typically used to measure the bearing width, while a micrometer or vernier caliper is used to measure the inner and outer diameters. This method of using two measuring tools is inefficient, and the micrometer or vernier caliper requires experience; different amounts of force applied to the vernier caliper can result in discrepancies (up to 0.05 mm) in the measured values, making it difficult to obtain accurate results.
[0004] To address this, we designed a wind turbine bearing testing device. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a wind turbine bearing testing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wind turbine bearing testing device, comprising:
[0008] The support has an inclined top surface. The top surface of the support is provided with an X-axis reference plate and a Y-axis reference plate. The reference surfaces of the X-axis reference plate and the Y-axis reference plate are both inclined upwards. The X-axis reference plate and the Y-axis reference plate form a positioning structure to limit the axial positioning of the workpiece being measured.
[0009] The first scale is vertically installed on the top surface of the support. The first scale is slidably connected to the first sliding block along its length direction, which is used to measure the width of the workpiece.
[0010] The second scale is mounted on the first sliding block and is set perpendicular to the first scale; the second scale is slidably connected to the second sliding block along its length direction and is used to measure the outer diameter of the workpiece;
[0011] The reference surfaces of the X-axis reference plate and the Y-axis reference plate are both inclined upwards at 30~60°.
[0012] Furthermore, the first scale is located at the intersection of the X-axis reference plate and the Y-axis reference plate, and the angle between the second scale and the X-axis reference plate and the Y-axis reference plate is 45°.
[0013] Furthermore, the second scale has unconventional graduations, and the ratio of the difference between two adjacent graduations of the unconventional graduations to the actual length is (1 + ... ):2.
[0014] Furthermore, the second scale is slidably connected to a third sliding block along its length, which cooperates with the second sliding block to detect the inner diameter of the workpiece.
[0015] Furthermore, the second scale has conventional graduations.
[0016] Furthermore, it also includes:
[0017] The screw is rotatably connected to the second sliding block, passes through the third sliding block, and is threadedly connected to it;
[0018] The torque handle, fixed to one end of the screw, is used to drive the screw to rotate in order to adjust the position of the third sliding block.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. Highly efficient integrated measurement, reducing tool changeover time: The vertical integration design of the first and second scales enables the measurement of workpiece thickness and outer diameter; combined with the unconventional scale of the second scale, the outer diameter value of the workpiece can be read directly; and combined with the third sliding block and conventional scale, the inner diameter of the workpiece can be measured, improving inspection efficiency.
[0021] 2. Precise positioning and self-locking structure to eliminate human error: The inclined top surface of the support and the reference plate, i.e. the sliding block, operate solely under the action of gravity, eliminating detection errors caused by human intervention and improving the accuracy of detection results;
[0022] 3. The screw fine-tuning mechanism improves the accuracy of inner diameter measurement: The adjustment mechanism, which consists of the third sliding block, screw, and torque handle, precisely controls the displacement of the third sliding block through threaded transmission, ensuring uniform contact force on both sides during inner diameter measurement. This eliminates the inner diameter measurement deviation caused by uneven manual force application in traditional calipers, and is especially suitable for the testing needs of high-precision wind turbine bearings.

[0029] Example 1, in conjunction with Appendix Figure 1-4 A wind turbine bearing testing device, comprising:
[0030] Support 1: Its top surface is an inclined surface, specifically, it is rectangular in shape; the inclination angle is 45°. The top surface of support 1 is fixedly mounted with an X-axis reference plate 2 and a Y-axis reference plate 3. Both reference surfaces are inclined upward at 45° and intersect at the center of the top surface of the support to form an L-shaped positioning structure, which is used to limit the axial positioning of the workpiece being measured.
[0031] The first scale 4 is vertically mounted on the top surface of the support 1, located at the intersection of the X-axis reference plate 2 and the Y-axis reference plate 3. The first scale 4 is slidably connected to a first sliding block 5 along its length. The first sliding block 5 can move up and down along the scale and is used to measure the width of the workpiece.
[0032] The second scale 6 is mounted on the first sliding block 5, perpendicular to the first scale 4, and forms a 45° angle with the X-axis reference plate 2 and the Y-axis reference plate 3. A second sliding block 7 is slidably connected to the second scale 6 along its length; the second sliding block 7 is used to measure the outer diameter of the workpiece.
[0033] The third sliding block 8 is slidably connected to the second scale 6 and cooperates with the second sliding block 7 to detect the inner diameter of the workpiece. The second scale 6 has two types of graduations: a standard graduation where the ratio of the difference between two adjacent graduations to the actual length is 1:1, used for measuring the inner diameter; and a non-standard graduation where the ratio of the difference between two adjacent graduations to the actual length is (1 + ...). ):2, used to directly read the outer diameter value.
[0034] Adjustment mechanism: includes a screw 9 and a torque handle 10. The screw 9 is rotatably connected to the second sliding block 7, passes through the third sliding block 8, and is threadedly connected to it. The torque handle 10 is fixed to one end of the screw 9, and rotating the handle drives the screw 9 to rotate, so as to precisely adjust the position of the third sliding block 8.
[0035] As needed, standard and non-standard scales are respectively located on both sides of the second scale 6. Preferably, the standard and non-standard scales can be distinguished by different colors or other markings to facilitate user identification and use of the correct scale.
[0036] Operating steps:
[0037] Positioning the workpiece: Place the workpiece on the inclined top surface of support 1. Under the action of gravity, the workpiece automatically conforms to the reference surfaces of the X-axis reference plate 2 and the Y-axis reference plate 3, thus completing the axial positioning.
[0038] Measuring width: Release the first sliding block 5 and let it slide along the first scale 4 to the upper surface of the workpiece. After releasing, the first sliding block 5 will press the second scale 6 against the workpiece under the action of gravity. Read the value on the first scale 4 directly to obtain the width of the workpiece.
[0039] Measuring the outer diameter: Using gravity, the second sliding block 7 moves along the second scale 6 to the outer wall of the workpiece, and the unconventional scale value of the second scale 6 is read to directly obtain the outer diameter dimension.
[0040] Measuring the inner diameter: Place the second sliding block 7 and the third sliding block 8 on both sides of the inner cavity of the workpiece. Rotate the torque handle 10 to drive the screw 9, so that the third sliding block 8 moves to contact the inner wall of the other side of the workpiece. Read the difference between the values of the two sliding blocks on the regular scale of the second scale 6, which is the inner diameter of the workpiece (inner ring inner diameter and outer ring inner diameter).
[0041] Example 2 differs from Example 1 in that the support tilt angle is adjusted to 30°, with the reference surfaces of the X-axis reference plate 2 and the Y-axis reference plate 3 tilting upwards. This is suitable for testing bearings with larger dimensions.
[0042] Example 3 differs from Example 1 in that the support tilt angle is adjusted to 60°, with the reference surfaces of the X-axis reference plate 2 and the Y-axis reference plate 3 tilting upwards. This is suitable for testing smaller bearings.
