[0036] When the oil-cooled motor is working, cold oil is injected into the oil supply pipe 3 through the cold oil supply mechanism in the prior art, and then diffused to each unit oil path in the oil delivery cavity layer 2. After the cold oil is transported along the C-shaped path, it is converged and discharged through the oil discharge pipe 4. The heat generated inside the motor is absorbed by the cold oil. In this way, the heat in the motor is taken away by the oil transportation. Fig. 9 It is understood that the oil is transported from left to right, and while being transported, the arc-shaped half panel 19 moves along the guide direction of the guide cross plate 21, so that the arc-shaped half panel 19 gives the oil fluid on the transport path a vertical impact, and at the same time Fig. 9 A space for oil reflux is reserved under the arc-shaped half panel 19, so that when the oil is transported from left to right, the upper and lower layers of oil are replaced. The lower layer of oil first absorbs the heat inside the motor at a close distance, and after the upper and lower layers of oil are replaced, the upper layer of oil also has the same opportunity to absorb heat at a close distance.

[0039] The impeller assembly 29 includes an L-shaped head frame 33 fixed on the motor housing 1, an impeller shaft 31 supported by one end of the L-shaped head frame 33, an impeller 32 fixed at one end of the impeller shaft 31, and a tail gear 30 fixed at the other end of the impeller shaft 31. The impeller 32 is distributed in the oil supply pipe 3, and the impeller shaft 31 is movably sleeved in a through hole opened on the L-shaped head frame 33.

[0040] The pressing device 28 includes a Y-shaped frame 38 fixed on the motor housing 1, a long worm 37 supported on one side of the Y-shaped frame 38, a short control shaft 39 vertically driven by one end of the long worm 37, a lap gear 40 fixed at one end of the short control shaft 39, a spring assembly 36 driven by the other end of the long worm 37, a surrounding rod 35 driven by the spring assembly 36, and a J-shaped spring 34 intercepting the surrounding rod 35.

The lap gear 40 is meshed with the tail gear 30, and one end of the J-shaped spring 34 is fixed to the Y-shaped frame 38.

[0041] The long worm 37 and the short control shaft 39 are respectively movably sleeved in two circular holes opened on the Y-shaped frame 38, and the long worm 37 is connected to the fixed bevel gear on the short control shaft 39 through meshing transmission.

[0042] The spring assembly 36 includes a center axis 43 vertically fixed on the end of the surrounding rod 35, a spring 42 fixed on the center axis 43, a ring plate gear 41 fixed outside the spring 42, and a Y-shaped binding plate 44 fixed on one side of the ring plate gear 41.

[0044] The specific transmission between the long horizontal frame 12 and the arc-shaped half panel 19 is: the long horizontal frame 12 moves to drive the side moving shaft 14 to rotate, and then the first ring tube 10 rotates to drive all the branch shafts 15, and the branch shafts 15 and the branch gears 17 rotate synchronously, and then a row of branch shafts 26 are transmitted through the long shaft gear 18, and then the free position shaft 24 and the free position gear 23 are controlled to rotate synchronously, and the free position gear 23 is meshed with the stationary guide cross plate 21 for transmission, so that while the free position gear 23 rotates, it moves along the length direction of the guide cross plate 21, and pulls the square flat slide cylinder 22 through the bracket 25, and the square flat slide cylinder 22 drives the arc-shaped half panel 19 to move, so that the arc-shaped half panel 19 travels between two adjacent C-shaped partition columns 6, stirring the oil fluid passing through, so that the oil layer close to the middle of the motor housing 1 and the oil layer far away in the oil fluid are replaced, so that the oil in the unit oil circuit can absorb heat more evenly.
