Description

Technical Field

[0001] The utility model relates to the field of wind power generation, in particular to a tool for measuring the assembly clearance of a tapered bearing. Background Art

[0002] The tapered bearings used in wind turbine gearboxes of different brands come in a variety of sizes. Differences in operating conditions also lead to different required clearance values ​​for the same tapered bearing model. Conventional bearing seat adjustment fixtures are too specialized to be suitable for the wind turbine operation and maintenance industry. Therefore, a universal fixture is needed to adjust bearing clearance.

[0003] The tapered bearings used in wind turbine gearboxes of different brands vary in specifications, including size, material, and load capacity. Wind turbine gearboxes operate in a complex and variable environment, where factors such as wind speed, temperature, and humidity affect the operating conditions of the bearings. This results in different clearance requirements for the same bearing model under different operating conditions. Due to the diversity of tapered bearings used in wind turbine gearboxes and the varying operating conditions, conventional tooling often cannot adapt to the requirements of different brands and operating conditions, resulting in poor or impossible adjustments.

[0004] In summary, given the complexity of adjusting the clearance of tapered bearings in wind turbine gearboxes, the development of a universal tool is essential. This tool should be versatile, adaptable, easy to operate, and highly precise to meet the needs of diverse brands and operating conditions. Furthermore, the tool's adaptability and adjustment efficiency can be further enhanced through modular design, adjustable mechanisms, high-precision measurement, and intelligent control.

A clamping device is provided on the upper end of the claw.

[0009] Furthermore, the clamping device includes an adjusting bolt and a pressing plate. The adjusting bolt passes through the protrusion on the upper end of the clamping claw, and the pressing plate is arranged between the adjusting bolt and the outer ring of the bearing.

[0010] Furthermore, the number of the grippers is 4, which are located on the same distribution circle.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Reference below Figures 1 to 2 , the utility model is further described:

[0024] The claws 1 are evenly distributed around the circumference to form a distribution circle. The upper and lower ends of the claws 1 protrude toward the center of the distribution circle and are used to hang on the bearing outer ring 2. A clamping device 11 is provided on the upper end of the claw 1.

[0025] The clamping device 11 includes an adjusting bolt 110 and a pressing plate 111 . The adjusting bolt 110 passes through the protrusion at the upper end of the clamping jaw 1 , and the pressing plate 111 is arranged between the adjusting bolt 110 and the bearing outer ring 2 .

[0026] In this embodiment, there are four grippers 1 located on the same distribution circle.

[0027] The material of the pressing plate 111 includes but is not limited to nylon.

[0028] The material of the adjusting bolt 110 includes but is not limited to high-strength alloy.

[0029] In one embodiment, the threaded portion of the adjusting bolt 110 is covered with a wear-resistant coating.

[0030] In this embodiment, three adjusting bolts 110 are provided on each claw 1 .

[0031] When in use, hang the four claws 1 on the bearing outer ring 2 with three adjusting bolts 110 respectively, for a total of 12 adjusting bolts 110. Place the pressure plate 111 on the upper end of the bearing outer ring 2 and press it down with the adjusting bolts 110. Use a micrometer to measure the total width of the two bearing outer rings 2 at four points in the circumferential direction and ensure that the height difference at the four points is within 0.02mm. Otherwise, increase or decrease the torque of the adjusting bolts 110 according to the height difference until the height difference is within 0.02mm. Figure 2 As shown, the total width a of the bearing is measured at this time, and then the widths b1 and b2 of the two bearing outer rings 2 are measured respectively. The actual width c of the spacer rings of the two bearing outer rings 2 is a-(b1+b2)+Ca (where Ca is the assembly clearance, which is determined according to the actual working conditions).

[0032] In one embodiment, an automatic adjustment system can be added to the tooling, and sensors, controllers, and actuators can be set on the jaws 1, so that the system can monitor the height difference of the four measuring points in real time and automatically adjust the tightening torque of the adjusting bolt 110 to keep the height difference within 0.02 mm.

[0033] After adding the automatic adjustment system, the tooling has the following advantages:

[0034] 1. Improve assembly accuracy and efficiency;

[0035] 2. Reduce human error and intervention;

[0036] 3. Suitable for large-scale automated production.

[0037] In one embodiment, in order to enhance the durability of the adjusting bolt, the adjusting bolt may be improved in terms of material and design, such as using high-strength alloy materials, adding a wear-resistant coating to the thread, or adopting a special thread design to reduce wear, thereby improving its durability and fatigue resistance.

[0038] This improved tooling has the following advantages:

[0039] 1. Extend the service life of the adjusting bolt;

[0040] 2. Reduce maintenance and replacement costs;

[0041] 3. Improve the overall reliability of the assembly structure.

[0042] In one embodiment, the pressure plate is optimized in design by optimizing its shape, size, and material, increasing its thickness and width, using higher-strength nylon material, or adding anti-slip texture to the surface of the pressure plate to improve its pressing effect and durability.

[0043] This improved tooling has the following advantages:

[0044] 1. Improve the clamping effect and ensure the stability of the bearing outer ring 2;

[0045] 1. Extend the service life of the pressing plate;

[0046] 2. Reduce assembly problems caused by insufficient clamping force.

[0047] In one embodiment, a data monitoring and recording function of the assembly process is added, and sensors and data acquisition systems are added to the claw 1 to monitor key parameters of the assembly process (such as height difference, tightening torque, etc.) in real time, and these data are recorded for subsequent analysis and improvement.

[0048] This improved tooling has the following advantages:

[0049] 1. Improve the traceability and controllability of the assembly process;

[0050] 2. Provide data support for continuous improvement and optimization;

[0051] 3. Helps identify and resolve potential assembly problems.

[0052] In one embodiment, the tapered bearing assembly clearance measuring tool provides a variety of assembly clearance options. In the actual production process, according to the actual application scenario and working conditions, by designing bearing spacer rings of different sizes or providing adjustable assembly clearance devices, a variety of assembly clearance (Ca) options are provided to meet the needs of different customers.

[0053] This improved tooling has the following advantages:

[0054] 1. Improve product flexibility and applicability;

[0055] 2. Meet a wider range of market demands;

[0056] 3. Enhance customer satisfaction and loyalty to the product.

[0057] In actual production, the measurement process can be optimized to improve measurement accuracy by adding more measurement points on the bearing outer ring 2, for example, increasing from four to eight or more. This provides a more comprehensive understanding of the bearing's width distribution and reduces the overall error caused by inaccuracies due to too few measurement points.
