Description

Technical Field

[0001] The utility model relates to the technical field of motor equipment, in particular to a high-speed motor with a cooling structure. Background Art

[0002] High-speed motors usually refer to motors with speeds exceeding 10,000 r / min. Because of their high speed and much smaller size than ordinary power motors, they are connected to the prime mover and eliminate the traditional reduction mechanism. High-speed motors have small rotational inertia and other reasons. Therefore, they have the advantages of high motor power density, effective material saving, high transmission efficiency, low noise, and fast dynamic response.

[0003] The reason why the motor gets hot is that electrical energy is converted into thermal energy. The motor will generate a certain amount of heat when it is working. If it works at high load for a long time, the temperature inside the motor will continue to rise and cause it to get hot. Under the existing technology, the cooling mechanism for high-speed motors generally sets a fan inside the high-speed motor to achieve the purpose of cooling by accelerating the air flow rate inside the high-speed motor. However, the bearing plays a role in supporting the rotor and reducing friction in the motor, and is also a position that is prone to heat. The effect of using a fan for cooling under the existing technology is very limited for the problem of bearing heating. When the bearing is in a high temperature state for a long time, the working efficiency and service life of the high-speed motor will be greatly reduced. For this reason, we propose a high-speed motor with a cooling structure. Utility Model Content

[0004] A technical problem to be solved by the present application is: how to effectively solve the problem of bearing heating when a high-speed motor works for a long time.

[0018] 1.

The water in the storage box is circulated through the connecting mechanism through the transmission mechanism, and most of the heat energy on the rotating shaft is absorbed during circulation, which greatly reduces the heat generated by the rotating shaft and the motor bearings, maintains the working efficiency of the high-speed motor, and extends the service life of the high-speed motor.

[0019] 2. By setting a rotating roller and an impeller, the rotating roller is used to drive the impeller to rotate. When the impeller rotates, centrifugal force is generated, and the water in the box two flowing through the connecting pipe one is continuously transported to the box one. When the water in the box one increases, it will flow from the connecting pipe one, the connecting pipe two and the connecting pipe three to the box two. This cycle is repeated to continuously absorb the heat generated on the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the connecting tube 1 31 is connected to the interior of the box body 1 21, one end of the connecting tube 2 32 is connected to the interior of the box body 2 22, and the connecting tube 3 33 is connected to the other ends of the connecting tube 1 31 and the connecting tube 2 32.

[0031] Embodiment 2:

[0032] See also Figure 3-4 The utility model provides a technical solution for a high-speed motor with a cooling structure: a high-speed motor with a cooling structure, comprising a transmission belt 4 arranged on a rotating shaft 11, the transmission belt 4 can transmit rotational kinetic energy, which is a prior art and will not be described in detail here, and the material of the transmission belt 4 can withstand high temperatures and will not be affected by the temperature on the rotating shaft 11, a transmission mechanism 5 arranged between the storage boxes 2, and the kinetic energy is transmitted to the transmission mechanism 5 through the transmission belt 4 to realize the water circulation between the storage boxes 2; the upper end of the transmission belt 4 is sleeved on the outer side wall of the rotating shaft 11, and the lower end of the transmission belt 4 is provided with a rotating roller 41; the transmission mechanism 5 includes a protective bin 51, and the protective bin 51 A connecting pipe 1 52 is fixedly provided on one side, a connecting pipe 2 53 is fixedly provided on the other side of the protection bin 51, an impeller 54 is provided inside the protection bin 51, and the impeller 54 has a plurality of circular arc-shaped blades. When the impeller 54 rotates, a large centrifugal force is generated, so that the water entering the center of the protection bin 51 from the connecting pipe 1 52 continuously moves toward the periphery of the inner wall of the protection bin 51, the rotating roller 41 penetrates the side wall of the protection bin 51 and is fixedly connected to the impeller 54, the other end of the connecting pipe 1 52 is fixedly provided on the side wall of the box body 22 and communicates with the interior thereof, and the other end of the connecting pipe 2 53 is fixedly provided on the side wall of the box body 21 and communicates with the interior thereof.

[0033] A storage box 2, a connecting mechanism 3, a transmission belt 4 and a transmission mechanism 5 are provided. The transmission belt 4 is used to transfer the kinetic energy of the rotating shaft 11 to the transmission mechanism 5. The water in the storage box 2 is circulated through the connecting mechanism 3 by the transmission mechanism 5. Most of the heat energy on the rotating shaft 11 is absorbed during circulation, and the heat generated by the rotating shaft 11 and the motor bearings is greatly reduced, thereby maintaining the working efficiency of the high-speed motor and extending the service life of the high-speed motor. A rotating roller 41 and an impeller 54 are provided. The rotating roller 41 is used to drive the impeller 54 to rotate. When the impeller 54 rotates, centrifugal force is generated to continuously transport the water in the box 2 22 flowing from the connecting pipe 1 52 into the box 1 21. When the water in the box 1 21 increases, it will flow from the connecting pipe 1 31, the connecting pipe 2 32 and the connecting pipe 3 33 to the box 2 22, and this cycle is repeated to continuously absorb the heat generated on the rotating shaft 11.

[0034] When the high-speed motor starts to work, after long-term work, its internal temperature gradually increases, and the temperature of the bearing also rises. At this time, the synchronous transmission of the transmission belt 4 will drive the rotating roller 41 to rotate, and the rotation of the rotating roller 41 will drive the impeller 54 in the protection bin 51 to start rotating. One end of the connecting pipe 1 52 is connected to the box body 2 22, and the other end is connected to the center of the protection bin 51. As the impeller 54 continues to rotate, the water entering the center of the protection bin 51 from the connecting pipe 1 52 will enter the box body 1 21 from the connecting pipe 2 53 connected to the edge of the protection bin 51 due to the centrifugal force. The water in the box body 1 21 will flow from the connecting pipe 1 31 at the upper end into the connecting pipe 3 33 due to the increase in pressure, and then enter the connecting pipe 2 32 from the connecting pipe 3 33 and enter the box body 2 22, and the cycle is repeated. When the water flows through the connecting pipe 1 31, the connecting pipe 2 32 and the connecting pipe 3 33, it will absorb a large amount of heat energy emitted from the rotating shaft 11 during the continuous flow process, so that the motor body 1 and the rotating shaft 11 thereon can be cooled.

When the water temperature continues to rise, it means that the inside of the box body 1 21 and the box body 2 22 has absorbed enough heat. If the motor body 1 still needs to continue working, it is necessary to start replacing the water in the box body 1 21 and the box body 2 22 through the water exchange port 55, and the water temperature in the box body 1 21 and the box body 2 22 can be observed in real time through the thermometer 56.
