[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0019] Embodiment one:

[0020] Please refer to Figures 1-3 The sealing structure of the output flange of primary speed reducer of converter tilting device, comprising:

[0021] Primary speed reducer box body 1;

[0022] Flange seat 2, the flange seat 2 is welded on the outside of primary speed reducer box body 1;

[0023] Gear shaft 3, the gear shaft 3 is arranged in the inside of primary speed reducer box body 1, the bearing 4 is installed on the gear shaft 3, the outside of the flange seat 2 is equipped with a plurality of put together screw post 5, and the put together screw post 5 is installed on the outside wall of the flange seat 2.

[0024] Specifically, the primary speed reducer box flange adopts overall sealing surface, and the machining precision of the primary speed reducer box flange face is sufficient to ensure the reliability of sealing, which is simpler than the traditional structure and reduces the processing difficulty.

[0025] From the above, the flange side bearing hole adopts the structure mode of blind hole, cancels the combined machining link of the flange and the end cover, reduces three machining parts (one end cover and two rubber plugs), cancels two positioning pins and connecting bolts for the end cover, no oil leakage accident occurs in actual use, and the utility model has the characteristics of reasonable structure, reduced machining difficulty, reduced assembly time, and reliable sealing of the overall sealing surface of the flange.
