Description

Technical Field

[0001] This utility model relates to a bearing lubrication device, and more particularly to a wind turbine bearing lubrication device. Background Technology

[0002] Wind power generation is the process of using wind energy to drive a wind turbine generator to rotate, which in turn drives the generator to produce electrical energy. In wind power generation, the main shaft of the generator is an important component that connects the wind turbine and the generator. Its main function is to transmit the rotational motion of the wind turbine to the generator so that the generator can produce electrical energy.

[0003] Lubricating the bearings of the motor spindle is an important step in ensuring the normal operation of the wind turbine generator set. Through lubrication, the lubricating oil can cover the metal surface, forming a protective film, reducing direct contact between metals, thereby reducing friction and wear. In addition, the lubricating oil can carry away the heat generated by friction, lowering the temperature of the bearing and playing a role in cooling and heat dissipation.

[0004] When lubricating bearings, they need to be erected and fixed in place to prevent the lubricating oil from spilling. Existing wind turbines have different shapes and bearing sizes on the main shaft. Therefore, a lubrication device that can effectively fix bearings of various sizes is needed. Utility Model Content

Detailed Implementation

[0021] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 3 This utility model provides a lubrication device for a wind turbine bearing 12, including an upright fixed platform 1. The front end of the fixed platform 1 is provided with a plurality of drive wheels 2 along the circumferential direction. The drive wheels 2 are rotatably connected to the fixed platform 1. A sliding rod 3 is provided on one side of the drive wheel 2. The sliding rod 3 is slidably connected to the front wall of the fixed platform 1. The front end of the sliding rod 3 all points to the center of the circle formed by the drive wheels 2. A rectangular rack 4 is provided on one side of the sliding rod 3 to mesh with the drive wheel 2. A clamping head 5 is provided at the front end of the sliding rod 3. A drive assembly is provided on the fixed platform 1 to drive the drive wheels 2 to rotate synchronously.

[0023] The generator bearing 12 is hoisted to the front center of the fixed platform 1. The drive wheel 2 is driven to rotate synchronously through the drive assembly. During the rotation, the drive wheel 2 drives the sliding rod 3 to move towards the center of the fixed platform 1 through the rectangular rack 4 that meshes with it. The clamping head 5 at the front end of the sliding rod 3 clamps the outer wall of the bearing 12. The ring-shaped sliding rod 3 will firmly clamp the bearings 12 of different sizes in the center of the fixed platform 1, thereby effectively fixing the bearings 12 of different sizes and facilitating the addition of lubricating oil for lubrication.

[0024] The drive assembly includes a drive disk 6, which is located at the front end of the fixed platform 1. The drive disk 6 is concentric with the circle formed by the drive wheel 2. The outer circumference of the drive disk 6 is provided with an annular rack 7 that meshes with the drive wheel 2.

[0025] The drive assembly also includes a drive motor 8, which is mounted at the rear end of the fixed platform 1, and the drive disk 6 is coaxially connected to the output shaft of the drive motor 8.

[0026] The fixed platform 1 is provided with a plurality of slides 9 along the circumferential direction, and the sliding rod 3 is slidably connected to the slides 9.

[0027] The top surface of the slide table 9 is provided with a groove 10 with a convex cross-section. The bottom of the sliding rod 3 is connected to a slider 11 that matches the groove 10. The sliding rod 3 is slidably connected to the groove 10 through the slider 11.

[0028] The drive motor 8 is electrically connected to an external power supply. The drive motor 8 drives the drive disk 6 to rotate, and the drive disk 6 drives the drive wheel 2, which meshes with it, to rotate synchronously. The height of the drive wheel 2 is greater than the thickness of the drive disk 6, so that the lower part of the drive wheel 2 meshes with the drive disk 6, and the upper part of the drive wheel 2 meshes with the rectangular rack 4. A slide table 9 is set to raise the movement trajectory of the sliding rod 3, so that the movement trajectory of the sliding rod 3 is above the drive disk 6. The drive wheel 2 and the rectangular rack 4 drive the sliding rod 3 to slide back and forth, thereby expanding or shrinking the circular area enclosed by the clamping head 5 to accommodate bearings 12 of different sizes.

[0029] The drive wheel 2 and sliding rod 3 are not located directly above the center of the drive disc 6, thus leaving space for the hoisting rope directly above the drive disc 6, so that the bearing 12 can be hoisted to the center of gravity of the drive disc 6 by a hoisting machine or other lifting equipment.

[0030] The clamping head 5 is Y-shaped, which can better clamp the outer wall of bearings 12 of different sizes.
