[0036] The pressure release device 9 also includes a unit frame 23 and a C-shaped spring clip 25. A plurality of unit frames 23 are evenly arranged between the outer gear ring 22 and the inner gear ring 27. One end of the unit frame 23 is fixed on the motor shaft 4. The unit frame 23 is provided with a first arc plate to be inserted into the annular groove opened on the inner wall of the outer gear ring 22, and the unit frame 23 is provided with a second arc plate to be inserted into the annular groove opened on the outer wall of the inner gear ring 27.

[0037] refer to Figure 8It is understood that the air ring group 10 includes a rotating ring plate 28, a rubber ring box 29 fixedly arranged inside the rotating ring plate 28, a plurality of uniformly arranged air ducts 30 connected to the inside of the rubber ring box 29, a fan 32 arranged in the air duct 30, and a fan shaft 31 fixed in the middle of the fan 32. The air duct 30 is fixed on a horizontal plate arranged on the unit frame 23, and the fan shaft 31 is movably sleeved in a through hole opened on the horizontal plate. One end of the fan shaft 31 is meshed and driven with a bevel gear fixed on the unit shaft 26 through a fixed bevel gear. The air diffuser box 11 is a ring shell with a concave cross section. The air diffuser box The rubber ring box 29 is a ring shell with a concave cross section. The rubber ring box 29 is provided with a plurality of through holes in a ring shape on the rotating ring plate 28 to connect the diffuser box 11 with the rubber ring box 29. The air cylinder 30 fixed on the rubber ring box 29 drives the rubber ring box 29 and the rotating ring plate 28 to rotate synchronously through a circular motion. The rubber ring box 29 can be slightly deformed at any time to buffer the radial vibration accidentally occurring during the rotation of the permanent magnet rotor 2, thereby ensuring the existence of a ventilation path among the air cylinder 30, the rubber ring box 29, the diffuser box 11 and the L-shaped flat tube 12.

[0038] When the motor shaft 4 is working and rotating, the driving device 13 moves in a circular motion along with the rotation of the motor shaft 4, and the circularly moving rubber wheel 21 contacts the inner wall of the thin tube of the stationary winding stator 3, so that the rubber wheel 21 continues to rotate, and then drives the neck shaft 19 through the roller shaft 20, and then drives the outer ring gear 22 to rotate through the overlapping worm 14, causing the annular spring 24 to contract and accumulate force.

After the inner ring gear 27 rotates a full circle, the protrusion on the inner ring gear 27 is intercepted by the C-shaped spring 25 again, and the annular spring 24 starts the next round of force accumulation.

The L-shaped flat tubes 12 blow air into the gap between two adjacent windings on the winding stator 3 to blow away the heat emitted by the winding. In summary, when the motor shaft 4 rotates, the rubber wheel 21 contacts and rotates to collect weak power, which is released in a concentrated manner through the annular spring 24, thereby providing strong power for the rotation of the fan 32. In this way, strong ventilation is achieved in the air ring group 10, and strong airflow is blown out from the L-shaped flat tube 12 at regular intervals to cool the winding stator 3. The air flowing through the air duct 30 can be the outside air of the motor, or it can be the low-temperature air pre-generated by the water cooling mechanism of the prior art.

The grease box 40 is a square groove shell for storing lubricant internally.

[0040] The reinforcement device 7 includes an integrated shaft 33, a row of non-rotating cylinders 35 fixed on the integrated shaft 33, a limiting short plate 34 supporting the integrated shaft 33, and a T-shaped flat mouth 36 coated with lubricant on one side of the non-rotating cylinder 35. One end of the T-shaped flat mouth 36 is fixedly connected to the oil delivery folding pipe 38, the limiting short plate 34 is fixed on the control cylinder 5, the integrated shaft 33 is movably sleeved in the through hole opened on the limiting short plate 34, and a through T-shaped plate hole is opened inside the T-shaped flat mouth 36.

[0041] The overlap group 37 includes an L-shaped fixed frame 44 with one end fixed on the grease box 40, a T-shaped brake plate 45 with one end sliding through a plate hole opened on the L-shaped fixed frame 44, a V-shaped block 43 fixed on the T-shaped brake plate 45, an inner slide rod 47 also supported by the T-shaped brake plate 45, a spring 49 sleeved on the inner slide rod 47, and a double-acting gear 50 fixed at one end of the inner slide rod 47, the inner slide rod 47 slides through the column hole opened on the T-shaped brake plate 45, the V-shaped block 43 is stuck in the V-shaped groove opened at one end of the integrated shaft 33, the screw rod 42 is movably sleeved in the column hole opened on the L-shaped fixed frame 44, the double-acting gear 50 contacts and meshes with the long shaft gear 51 fixed on the unit shaft 26 through axial movement, the spring 49 is supported between the double-acting gear 50 and the T-shaped brake plate 45, and an intercepting ring is also fixed on the inner slide rod 47 to limit the axial movement range of the double-acting gear 50.

[0043] The reinforcing device 7 is installed on the control cylinder 5. The rotation of the control cylinder 5 will drive the reinforcing device 7 to move in a circle, and the non-rotating cylinder 35 and the inner wall of the thin cylinder of the winding stator 3 will slide in an offset manner. The non-rotating cylinder 35 does not rotate because the V-block 43 is positioned in the integrated shaft 33, and then the integrated shaft 33 and the non-rotating cylinder 35 will not rotate. Grease is attached to the outer wall of the non-rotating cylinder 35, so that the inner wall of the thin cylinder of the winding stator 3 and the non-rotating cylinder 35 can slide in an offset manner smoothly. The reinforcing device 7 assists in limiting the control cylinder 5 by padding between the control cylinder 5 and the winding stator 3 to reduce the vibration probability of the rotating control cylinder 5. However, the grease on the outer wall of the non-rotating cylinder 35 is consumed by friction and needs to be replenished in time. The present invention automatically ensures the supply of grease through the lubrication mechanism 8. Specifically, the surface of the non-rotating cylinder 35 becomes dry, and the offset sliding between the thin cylinder of the winding stator 3 and the non-rotating cylinder 35 will cause the non-rotating cylinder 35 to slide in an offset manner. When the gear 35 rotates, the integrated shaft 33 will forcibly break through the V-block 43, and the V-block 43 will be pushed back and moved, and the V-block 43 drives the T-type brake plate 45 to move horizontally, and then pushes the double-acting gear 50 through the spring 49. The double-acting gear 50 moves axially to establish transmission with the long shaft gear 51, so that the power for conveying grease appears. Specifically, the unit shaft 26 rotates intermittently, and then the long shaft gear 51 drives the double-acting gear 50 to rotate, and then the travel gear 41 is driven by the guide shaft 48, causing the screw rod 42 to rotate slowly, and the push plate 39 screwed to the screw rod 42 is pushed into the grease box 40, and the grease in the grease box 40 is squeezed out, and then it is diffused into a row of T-shaped flat nozzles 36 through the oil delivery folding pipe 38, and the grease discharged from the T-shaped flat nozzles 36 is smeared on the rotating non-rotating cylinder 35, so that a layer of lubricating oil film is regenerated on the outer wall of the non-rotating cylinder 35.
