[0025] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0026] In this disclosure, unless otherwise stated, directional words such as "upper, lower, high, low, top, bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. Figure 1 The directions of the drawings shown. "Inside" and "outside" refer to the inside and outside of the corresponding component outlines.

In addition, in the description with reference to the drawings, the same symbols in different drawings represent the same elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.
[0027] For ease of understanding, please refer to the attached Figures 1 to 4 , the specific structure and working principle of the yaw reducer disclosed in the present invention are explained in detail with reference to the embodiments.
[0028] The present disclosure relates to a yaw speed reducer that can effectively avoid the problem of drive gear 2 being deflected and damaged due to the uneven top surface of the mounting platform 3. Figure 1 The yaw reducer disclosed in the present invention includes a drive motor 1, a drive gear 2, a mounting platform 3 and a leveling gasket 4, wherein the mounting platform 3 is connected to the yaw unit to provide a mounting position for the drive motor 1 and the drive gear 2. The drive motor 1 is used to drive the drive gear 2 to rotate, and a mounting seat 11 is provided on the drive motor 1. The mounting seat 11 can be docked with the mounting platform 3 to complete the installation of the drive motor 1, and after the installation is completed, the drive gear 2 can mesh with the yaw large tooth in the yaw unit.
[0029] When the mounting platform 3 is manufactured, the top surface of the mounting platform 3 may be uneven due to problems with the manufacturing equipment or testing. The yaw reducer leveling gasket 4 disclosed in the present invention is located between the mounting seat 11 and the mounting platform 3, and includes a contact surface 41 located at the top and in contact with the bottom surface of the mounting seat 11, and an adjustment surface 42 located at the bottom and in contact with the top surface of the mounting platform 3. The contact surface 41 is a plane, which can ensure that the bottom surface of the mounting seat 11 in contact with it can remain flat, avoiding the drive gear 2 from being offset and damaged after the installation is completed. The adjustment surface 42 can fit with the uneven top surface of the mounting platform 3, ensuring that the contact surface 41 of the leveling gasket 4 in contact with the mounting seat 11 is horizontal after the installation is completed.
[0030] The yaw reducer disclosed in the present invention is provided with a leveling gasket 4 between the mounting seat 11 and the mounting platform 3. The uneven top surface of the mounting platform 3 caused by other reasons is leveled by the leveling gasket 4, and then contacts the mounting seat 11 through the horizontal contact surface 41, thereby ensuring the levelness of the mounting seat 11 and avoiding abnormal tooth clearance and damage caused by unbalanced load of the driving gear 2 after the installation is completed.
[0031] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The leveling gasket 4 has a non-uniform thickness to construct a non-planar structure of the leveling plane 42. Since the leveling gasket 4 is a sheet with a non-uniform thickness, when it contacts the top surface of the mounting platform 3, the leveling gasket 4 can be manufactured with appropriate thicknesses at different positions according to the unevenness of the top surface of the mounting platform 3 to ensure that the leveling gasket 4 can fit the top surface of the mounting platform 3 when placed on the mounting platform 3, so as to ensure that the contact surface 41 remains horizontal, and the yaw reducer in contact with the contact surface 41 can remain stable during operation and will not shake due to the unevenness of the top surface of the mounting platform 3, causing damage to the drive gear 2 or the yaw gear. Of course, in other embodiments, the leveling gasket 4 can also have other structures, such as protrusions of different lengths or other non-planar structures on the leveling plane 42 of the leveling gasket 4 to ensure that the contact surface 41 remains horizontal after the leveling gasket 4 is placed on the mounting platform 3 with an uneven top surface, and to ensure the stability of the yaw reducer.
[0032] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The leveling washer 4 is annular in shape, with a through hole 43 formed in the center to facilitate the passage of the drive shaft of the drive motor 1 and the drive gear 2 through the leveling washer 4. Furthermore, the annular leveling washer 4 is more convenient to manufacture. Of course, in other embodiments, the leveling washer 4 may also be of other shapes, depending on the actual situation, and this disclosure does not limit this.
[0033] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A plurality of mounting holes 44 distributed along the circumferential direction are provided on the leveling gasket 4. The mounting holes 44 pass through the leveling gasket 4 so that the mounting bolts on the mounting platform 3 can pass through the leveling gasket 4 and cooperate with the mounting seat 11 on the drive motor 1 to complete the installation of the leveling gasket 4 and the drive motor 1.
[0034] In one embodiment of the present disclosure, the leveling gasket 4 is made of a metal material, such as stainless steel or cast iron. Using a metal material to make the leveling gasket 4 provides good strength and prevents deformation under the pressure of the yaw reducer, thereby creating a gap between the leveling gasket 4 and the mounting seat 11 or the mounting platform 3. Furthermore, using a metal material can extend the service life of the leveling gasket 4. Of course, in other embodiments, the leveling gasket 4 can also be made of other materials as long as they can ensure strength. The specific material can be determined based on actual conditions and is not limited by the present disclosure.
[0035] In a second aspect of the present disclosure, a leveling assembly for a yaw reducer is provided, which can solve the problem of damage to the drive gear 2 caused by the uneven top surface of the mounting platform 3. Figure 4 The leveling assembly of the present disclosure includes a detection component 5 and the leveling gasket 4 described in the above embodiment. The detection component 5 can measure the flatness of the top surface of the mounting platform 3. Then, the leveling surface 42 of the leveling gasket 4 can be processed based on the flatness measured by the detection component 5, ensuring that the leveling surface 42 of the leveling gasket 4 can be affixed to the top surface of the mounting platform 3 after processing, and that the contact surface 41 can remain horizontal after affixation.
[0036] In one embodiment of the present disclosure, see Figure 4 The detection component 51 includes a test piece 51. The test piece 51 is annular and can be adapted to the shape of the leveling gasket 4, and the bottom surface of the test piece 51 is a planar structure. When it is necessary to measure the flatness of the top surface of the mounting platform 3, the test piece 51 can be placed on the top surface of the mounting platform 3 first. If the top surface of the mounting platform 3 is not a plane, when the bottom surface of the plane structure of the test piece 51 contacts the top surface of the mounting platform 3, a gap will be generated between the top surface of the mounting platform 3. After the gap is generated, the staff can measure the height of the gap and then manufacture the leveling gasket 4 based on the measured gap data to ensure that the manufactured leveling gasket 4 can fit on the top surface of the mounting platform 3 and the contact surface 41 can remain horizontal. If the top surface of the mounting platform 3 is a plane, no gap will be generated and the subsequent installation of the yaw reducer can be continued.
[0037] In one embodiment of the present disclosure, see Figure 4A handle 511 is provided on the top surface of the test piece 51. The handle 511 can facilitate the staff to move the position of the test piece 51 and switch between different installation platforms 3. In addition, multiple handles 511 can be provided to facilitate collaboration among multiple staff members.
[0038] In one embodiment of the present disclosure, see Figure 4 The detection assembly 5 also includes a measuring piece 52, which can be used to measure the height of the gap between the bottom surface of the test piece 51 and the top surface of the mounting platform 3, so that the staff can collect relevant data to manufacture the leveling gasket 4. In some embodiments of the present disclosure, the measuring piece 52 is a feeler gauge, the cross-section of the feeler gauge can be triangular, and it has a measuring slope 521 and scale lines. When measuring the height of the gap between the bottom surface of the test piece 51 and the top surface of the mounting platform 3, it is only necessary to insert the tip of the feeler gauge into the gap until the feeler gauge can no longer move. The height of the gap can then be determined by the scale on the feeler gauge or by the staff. Of course, in other embodiments, the measuring piece 52 can also be of other structures, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0039] When the leveling assembly disclosed in the present invention is used, it is first necessary to measure the flatness of the top surface of the mounting platform 3 using the test piece 51 in the detection assembly 5. During the flatness measurement process, a gap will be generated between the bottom surface of the test piece 51 and the top surface of the mounting platform 3. At this time, the height of the gap can be measured by the measuring piece 52 to obtain relevant data for manufacturing the leveling gasket 4, ensuring that the manufactured leveling gasket 4 can be attached to the top surface of the mounting platform 3 and that the contact surface 41 can remain horizontal. The leveling assembly disclosed in the present invention can detect the flatness of the mounting platform 3. If the flatness of the mounting platform 3 is unqualified, the leveling gasket 4 can be manufactured based on the measured data to ensure that after the yaw reducer is installed, the drive gear 2 will not be damaged due to abnormal tooth clearance and unbalanced load.
[0040] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0042] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
