The above definitions are only used to explain and illustrate the present disclosure and should not be construed as a limitation to the present disclosure.

[0027] For ease of understanding, hereinafter, reference is made to the appended Figures 1 to 2 drawings, and the specific structure and working principle of the seal ring installation tool of the present disclosure are described in detail in conjunction with the embodiments.

[0028] The present disclosure relates to a seal ring installation tool, which can ensure uniform force on the seal ring during seal ring installation, and avoid problems such as position deviation or damage of the seal ring after installation. Refer to Figure 1 and Figure 2 , the seal ring installation tool of the present disclosure includes a support base 1 and an installation ring 2. The support base 1 serves to support the seal ring and the installation ring 2, and can be made of a metal material, and is circular or rectangular for easy adaptation to the seal ring, so that the support base 1 has good strength. The bottom surface of the installation ring 2 is fixedly connected to the support base 1, and the outer diameter of the installation ring 2 is set to be adapted to the inner diameter of the seal ring to be installed, so that the seal ring to be installed can be sleeved on the installation ring 2 during installation. A pick-and-place hole 21 is also formed at the center position of the installation ring 2, and the pick-and-place hole 21 penetrates the support base 1. After the seal ring is installed by the seal ring installation tool, the operator can insert his hand or a tool into the pick-and-place hole to remove the seal ring installation tool.

[0029] Specifically, during the installation of the seal ring, first, the seal ring needs to be sleeved on the installation ring 2, so that the inner wall of the seal ring fits on the outer wall of the installation ring 2, and the bottom surface of the seal ring also fits on the top surface of the support base 1. Then, the support base 1 is moved to the position where the seal ring is to be installed, and the support base 1 is inverted so that the seal ring is located in the position to be installed. Finally, the operator taps the support base 1 with a tool to complete the installation of the seal ring. After the seal ring is installed, the operator can also remove the seal ring installation tool through the pick-and-place hole 21 for the next use.

[0030] For the seal ring installation tool of the present disclosure, when installing the seal ring, the seal ring is sleeved on the installation ring 2, and then the installation of the seal ring is completed by knocking the support seat 1. Since the bottom surface of the seal ring fits on the top surface of the support seat 1, after the support seat 1 is stressed, it can be evenly transmitted to the seal ring, ensuring uniform stress on the seal ring and avoiding position deviation or damage caused by uneven stress after the installation of the seal ring, thereby improving the installation efficiency and quality of the seal ring.

[0031] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , a chamfer 22 is provided at the edge of the top surface of the installation ring 2. By providing the chamfer 22, it can play a role of transition and guidance when the seal ring is sleeved on the installation ring 2, making the sleeving process of the seal ring more convenient and fast, and reducing the occurrence of the situation where the seal ring is stuck on the installation ring 2. In other embodiments of the present disclosure, refer to Figure 1 and Figure 2 , the installation ring 2 is conical, and the diameter of the bottom surface is larger than that of the top surface. Such a setting can make the inner wall of the seal ring fit more tightly on the inner wall of the installation ring 2 after the seal ring is installed on the installation ring 2, ensuring the stability of the seal ring during the installation process and the movement process of the support seat 1, and avoiding the seal ring falling off the installation ring 2. Of course, in other embodiments, other structures can also be provided on the installation ring 2 to ensure the stability of the seal ring and the convenience of installation, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0032] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , the height of the installation ring 2 is set to be at most the same as that of the seal ring to be installed. When the seal ring is installed on the installation ring 2, if the height of the installation ring 2 is higher than that of the seal ring, it will cause the seal ring to be difficult to fall off the installation ring 2 during installation, resulting in the failure of the installation of the seal ring. And setting the height of the installation ring 2 to be at most the same as that of the seal ring to be installed can ensure that the bottom surface of the seal ring can definitely contact the position to be installed, thus facilitating the installation of the seal ring.

[0033] During the actual use process, the size of the seal ring often needs to be changed according to the equipment. To improve the applicability of the seal ring installation tool of the present disclosure, in an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , the installation ring 2 is detachably connected to the support seat 1. In this embodiment, a plurality of threaded holes 3 are provided on the installation ring 2 and the support seat 1. When it is necessary to fixedly connect the installation ring 2 to the support seat 1, it is necessary to connect through a connecting member 4, and the connecting member 4 can be a bolt.

[0034] The connection process is as follows: The end of the connecting member 4 passes through the mounting ring 2 and the threaded hole 3 on the support base 1 at one time, so that the threads on the connecting member 4 are matched with the threads on the inner wall of the threaded hole 3 to complete the fixation. After the fixation is completed, the tip of the connecting member 4 should not be higher than the top surface of the mounting ring 2 to prevent the connecting member 4 from interfering with or scratching the equipment where the sealing ring needs to be installed during the installation of the sealing ring. Of course, in other embodiments, the mounting ring 2 can also be detachably connected to the support base 1 in other ways, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0035] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , a flexible pad 23 is provided on the top of the mounting ring 2. The flexible pad 23 can be made of materials such as rubber and resin and has a certain buffering effect. By providing the flexible pad 23, when the top surface of the mounting ring 2 abuts against the position where the sealing ring is to be installed, it can play a certain buffering role. On the one hand, it can buffer the impact force on the equipment when the staff knocks on the support base 1, and on the other hand, it can also buffer the impact force on the equipment when the mounting ring 2 is placed. And, in order to facilitate the sealing ring to be sleeved on the mounting ring 2, a chamfer 22 can also be provided at the outer edge of the top surface of the flexible pad 23.

[0036] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , anti-slip lines 211 are provided on the inner wall of the access hole 21. By providing the anti-slip lines 211, when the staff takes out the support base 1 through the access hole 21, it can increase the friction between the fingers or tools of the staff and the inner wall of the access hole 21, and prevent the support base 1 from being difficult to take out. Refer to Figure 1 , in this embodiment, the anti-slip lines 211 are annular grooves provided on the inner wall of the access hole 21 for the fingers or tools of the staff to grab to increase the friction. Of course, in other embodiments, the anti-slip lines 211 can also be of other types, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0037] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , a holding part 11 is provided on the support base 1. By providing the holding part 11, when the staff needs to move the support base 1, a position is provided for the staff to hold and move. In this embodiment, the support base 1 is circular, and the holding part 11 includes a plurality of grooves 111. The grooves 111 are arc-shaped grooves, which are convenient for cooperating with the fingers or tools of the staff. And the plurality of grooves 111 are evenly distributed in the circumferential direction of the support base 1, and can also enable the staff to cooperate with one or more grooves 111 on the support base 1 when at different positions of the support base 1 to move the support base 1.

[0038] In an embodiment of the present disclosure, a sealing ring installation tool is used for installing a sealing ring in a pitch reducer of a wind turbine generator.
