Embodiment 1
[0098] Such as figure 1 As shown, the gearbox of the present application includes a gearbox housing 100 , a transmission mechanism 200 , a rotating impeller 300 , an oil pumping assembly 400 and a blowing assembly 500 .
[0099] The gearbox casing 100 is the casing of the gearbox, which supports the internal components of the gearbox; the transmission mechanism 200 is a functional part of the gearbox, positioned inside the gearbox casing 100, which includes gear shaft 210 .
[0100] The rotating impeller 300 is rotatably and fixedly connected to the gearbox casing 100, and rotates under the blowing of the blowing assembly 500; further, the rotating impeller 300 includes an impeller main body 310, a center Rotary body 320, heat dissipation oil pipe 330 and oil liquid inlet and outlet pipe 340; the impeller main body 310 is fixed on the top of the central rotating body 320 for supporting and positioning the heat dissipation oil pipe 330; the central rotating body 320 For oil d...
Embodiment 2
[0113] In order to further improve the heat dissipation effect, the embodiment of the present application adds an air cooling assembly 700 on the basis of the above embodiments, and adds an air deflector 110 on the gearbox housing 100;
[0114] Further, the wind deflector 110 plays a role in guiding the flow direction of the gas blown out by the blowing assembly 500, and the wind deflector 110 includes a U-shaped wind deflector 111 and a straight plate 112; the U-shaped wind deflector 111 as figure 1 and figure 2 As shown, it is fixed on the gearbox casing 100, and the axial direction is the same as the axial direction of the impeller main body 310; the wind deflector 110 includes a straight part and a curved part; The number is two; the straight plate 112 is positioned between the two straight plate parts and fixed on the gearbox housing 100 for supporting and positioning the air cooling assembly 700; the blowing assembly 500 is positioned between the straight plate 112 an...
Embodiment 3
[0118] Considering that the effective filtering time of the filter sponge 610 in the first embodiment is limited, the filtering effect is often lost due to the accumulation of impurities, and regular replacement is cumbersome.
[0119] preferred, such as Figure 10 As shown, the filter sponge 610 includes a ring-shaped sponge body 611, and the ring-shaped sponge body 611 is in the shape of a ring (shaped like a ring with a gap); the number of the sponge placement openings 421 is two, respectively positioned on the On both sides of the pumping assembly housing 420, the sponge placement opening 421 is located on the side wall of the pumping assembly housing 420 close to the oil inlet 460 and the oil outlet 470; cancel the placement opening The setting of the cover plate 422; the filter sponge 610 passes through the two sponge placement openings 421;
[0120] The oil pumping assembly 400 also includes a casing closure assembly 490; the casing closure assembly 490 is used to bloc...
