Unit oil circuits, each of which is provided with a plurality of flow stirrers 7 for stirring the oil, the oil delivery cavity layer 2 is also provided with a traverse device 8, an active device 9 connected to one end of the traverse device 8, a first ring cylinder 10 driven by the other end of the traverse device 8, and a plurality of evenly arranged long gear sets 11 vertically driven by the first ring cylinder 10, and each long gear set 11 drives a row of flow stirrers 7 on one side, the active device 9 is distributed at the joint of the oil delivery cavity layer 2 and the oil supply pipe 3, and the first ring cylinder 10 is movably stuck in the ring groove opened in the motor housing 1.

[0034] refer to Figure 4 It is understood that the traverse device 8 includes a limit rail seat 13 fixed on the motor housing 1, a side moving shaft 14 supported on the limit rail seat 13, and a long cross frame 12 sliding through a long groove opened on the limit rail seat 13. One end of the side moving shaft 14 is connected to a row of teeth meshing transmission arranged on the long cross frame 12 through a fixed gear, and the other end of the side moving shaft 14 is connected to a row of teeth meshing transmission arranged in an arc shape on the first ring cylinder 10 through a spiral tooth. The side moving shaft 14 is movably sleeved in a through hole opened on the limit rail seat 13.

[0035] refer to Figure 5 It is understood that the long gear set 11 includes a dividing block 16 fixed on the motor housing 1, a sub-shaft 15 supported on the dividing block 16, a sub-gear 17 fixed at one end of the sub-shaft 15, and a long shaft gear 18 meshingly connected to one side of the sub-gear 17, the other end of the sub-shaft 15 is meshingly connected to the arc-shaped rack fixed on the first ring cylinder 10 through a fixed gear, one end of the long shaft gear 18 is movably sleeved in the column hole opened on the dividing block 16 by setting an axis body, and the long shaft gear 18 passes through the through hole opened on the C-shaped partition column 6, and the sub-shaft 15 is movably sleeved in the through hole opened on the dividing block 16.

[0036] refer to Figure 6 It is understood that the agitator 7 includes a mobile control part 20 transmission-connected to the long shaft gear 18, an arc-shaped half panel 19 transported on the mobile control part 20, and a guide cross plate 21 guiding the mobile control part 20, the guide cross plate 21 is vertically fixed on the C-shaped partition column 6, and the arc-shaped half panel 19 and the C-shaped partition column 6 are parallel to each other.

[0037] 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. Figure 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 Figure 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. In this way, the present invention uses the arc-shaped half panel 19 to impact and stir the oil in the unit oil circuit on the vertical oil transport path to make the oil absorb heat more evenly.

[0039] refer to Figure 10 It is understood that the active device 9 includes an impeller group 29 for converting fluid power in the oil pipe 3, a pressure generating device 28 for collecting power from the impeller group 29, and a swing column 27 for establishing transmission between the long cross frame 12 and the pressure generating device 28.

[0040] 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.

[0041] The hair 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 at one end of the long worm 37, a lapping gear 40 fixed at one end of the short control shaft 39, a spring assembly 36 driven at the other end of the long worm 37, a surrounding rod 35 driven by the spring assembly 36, and a J-shaped elastic piece 34 that intercepts the surrounding rod 35. One end of the swing column 27 is hinged to the surrounding rod 35, and the other end is hinged to the long cross frame 12. The lapping gear 40 is meshed and connected with the tail gear 30. One end of the J-shaped elastic piece 34 is fixed on the Y-shaped frame 38.

[0042] 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 meshed and driven by a fixed bevel gear and a bevel gear fixed on the short control shaft 39.

[0043] The spring assembly 36 includes a middle shaft 43 vertically fixed at the end of the surrounding rod 35, a spring 42 fixedly sleeved on the middle shaft 43, an annular plate gear 41 fixedly sleeved outside the spring 42, and a Y-shaped binding plate 44 fixed on one side of the annular plate gear 41. The middle shaft 43 is movably sleeved in a through hole opened on the Y-shaped frame 38, and the middle shaft 43 is also movably sleeved in a through hole opened in the middle of the Y-shaped binding plate 44. The annular plate gear 41 is meshed with the spiral teeth on the long worm 37.

[0044] The cold oil conveyed in the oil supply pipe 3 impacts the impeller 32. The rotation of the impeller 32 drives the impeller shaft 31, and then drives the lapping gear 40 through the tail gear 30. Next, the long worm 37 is driven through the short control shaft 39. Furthermore, the continuous rotation of the annular plate gear 41 causes the spring 42 to contract and store energy. After the energy storage is saturated, the middle shaft 43 is pressured to rotate. Then, the surrounding rod 35 breaks through the interception of the J-shaped elastic piece 34, and the surrounding rod 35 rotates quickly for one circle. The swing column 27 is used to swing and control the long cross frame 12 to complete a periodic motion. The motion mode of the long cross frame 12 corresponds to Figure 6 the movement of the arc-shaped half panel 19 in Figure 6 Specifically, the arc-shaped half panel 19 in

[0045] The specific transmission between the long horizontal frame 12 and the arc-shaped half panel 19 is as follows: the movement of the long horizontal frame 12 drives the rotation of the side drive shaft 14, and then the rotation of the first ring cylinder 10 drives all the sub-shafts 15. The sub-shafts 15 and the sub-gears 17 rotate synchronously. Subsequently, a row of branch shafts 26 is driven through the long shaft gear 18, thereby controlling the synchronous rotation of the floating shaft 24 and the floating gear 23. The floating gear 23 meshes with the stationary guide horizontal plate 21 for transmission. In this way, while the floating gear 23 rotates, it moves along the length direction of the guide horizontal plate 21, pulls the square flat sliding cylinder 22 through the bracket 25, and the square flat sliding cylinder 22 drives the arc-shaped half panel 19 to move. Therefore, the arc-shaped half panel 19 travels between two adjacent C-shaped partition columns 6, agitating the passing oil fluid, so that the oil layers near and far from the middle of the motor housing 1 in the oil fluid are replaced, and the oil in the unit oil circuit can absorb heat more evenly.
