[0014] Figure 1 It is a structure schematic diagram for the anti - jamming device for the breathing valve of the speed reducer according to the utility model embodiment.

[0015] Referring to Figure 1 , according to the anti - jamming device for the breathing valve of the speed reducer according to the utility model embodiment, it is arranged above the box body of the speed reducer 1, and includes: a breather valve 2, a flange seat 3, a mounting column 4 and first backflow baffle 5 and second backflow baffle 6. One end of the breather valve 2 is fixedly arranged on the surface of the flange seat 3, and the other end of the breather valve 2 is connected with the outside, so as to provide a channel for the exhaust and heat dissipation of the speed reducer 1. The flange seat 3 is fixedly connected with the breather valve 2 and the mounting column 4, the mounting column 4 is fixedly arranged on the box body of the speed reducer 1, and the mounting column 4 is provided with a backflow cavity 41 connected with the gear box in the speed reducer 1, and the water vapor in the speed reducer 1 is condensed through the backflow cavity 41. The first backflow baffle 5 and the second backflow baffle 6 are respectively fixedly arranged in the backflow cavity 41, and the first backflow baffle 5 and the second backflow baffle 6 are oppositely arranged.

[0016] The first backflow baffle 5 and the second backflow baffle 6 are both flexible metal sheets, one end of the first backflow baffle 5 is fixed on the inner wall of the backflow cavity 41 by welding or other fixing methods, and one end of the second backflow baffle 6 is fixed on the inner wall of the backflow cavity 41 by welding or other fixing methods. Inside the backflow cavity 41, the first backflow baffle 5 is located above the second backflow baffle 6.
