Example two

While realizing a compact and miniaturized design, the heat dissipation requirement of the stator 2 in the permanent magnet electric drum 100 needs to be satisfied, and for this purpose, a first cooling flow channel is provided on the main shaft 1, and the first cooling flow channel is used for supplying cooling liquid to flow and cooling the stator 2. In order to reduce the overall size to the maximum extent, the main shaft 1 is optimally designed in the following structure, the main shaft 1 includes a shaft body 10 and a heat conduction sleeve 15, a water inlet channel 12 and a water outlet channel 13 are arranged in the shaft body 10, a water tank 14 is arranged on the circumferential surface of the shaft body 10, the heat conduction sleeve 15 is arranged outside the main shaft 1 and covers the water tank 14 in a sealing manner, a water flow channel is formed between the water tank 14 and the heat conduction sleeve 15, and the water inlet channel 12 and the water outlet channel 13 are respectively communicated with the water flow channel to form a first cooling flow channel.

In the in-service use process, during outside coolant liquid enters into axis body 10 from inhalant canal 12, during the coolant liquid will flow into the basin 14 that forms on the axis body 10 outer peripheral face, the coolant liquid can absorb the heat that stator 2 produced through heat conduction cover 15, and then plays the effect to stator 2 rapid cooling that dispels the heat.

Since the water tank 14 is directly formed on the outer circumferential surface of the shaft body 10 to form the first cooling flow channel, it is not necessary to additionally add a frame to construct the cooling flow channel, on one hand, the outer diameter of the stator 2 is reduced to reduce the overall size of the permanent magnet electric drum 100, and on the other hand, the stator 2 is directly fixed on the shaft body 10 to dissipate heat, thereby reducing the manufacturing cost and simplifying the assembly process.

In this case, the heat conducting sleeve 15 may be a sleeve of an integral structure, which is sleeved outside the shaft 10 to cover the water tank 14, thereby forming a water flow channel. Typically, during assembly, the sleeve is heated and the shaft 10 is cooled, and the two are inserted together to form a closed water flow path.

Preferably, in order to minimize the radial size of the main shaft 1, the heat-conducting sleeve 15 of a split structure is adopted. That is, the heat-conducting sleeve 15 includes a plurality of sealing strips 151, and the sealing strips 151 are hermetically disposed in the water tank. Specifically, the plurality of sealing strips 151 are caught in the water tub 14 to shield the water tub 14.

Compared with the sleeve sleeved on the shaft body 10, the assembling difficulty is obviously lower, and the limitation of the length of the shaft body 10 is avoided, so that the assembling precision and quality are improved.

Wherein, for the stator 2, the stator 2 comprises a core (not labeled) and a winding (not labeled) disposed on the core; the iron core is a cylindrical structure, and the outer surface of the iron core is provided with a groove structure for placing windings, and the specific structural form of the stator 2 is not limited herein.

In order to meet the requirement of uniform heat dissipation, a plurality of water tanks are disposed on the circumferential surface of the shaft 10, and two adjacent water tanks 14 are communicated with each other to form the water tank 14. Specifically, the coolant inputted from the water inlet channel 12 sequentially flows through the water grooves 14 and is outputted from the water outlet channel 13, so that the coolant can comprehensively flow through the outer peripheral surface of the shaft body 10, and the iron core outside the heat conducting sleeve 15 is subjected to comprehensive and effective heat absorption and temperature reduction treatment.

In addition, a blocking rib 141 is formed between two adjacent water tanks 14; in the water flow direction, the end of the rib 141 is provided with a notch 142, and two adjacent water tanks 14 are communicated through the notch 142. Specifically, the rib 141 separates two adjacent water tanks 14, and during the flowing of the cooling liquid in the water tanks 14, the cooling liquid in the upstream water tank 14 enters the downstream water tank 14 through the notch 142. Thus, the coolant can flow through the water grooves 14 in sequence to flow over the entire circumference of the shaft 10, thereby achieving an overall and efficient endothermic cooling process.

The shaft body 10 is provided with a water inlet passage 12 and a water outlet passage 13 at one end portion of the shaft body 10, and a cable passage 11 at the other end portion of the shaft body 10.

Similarly, a first through hole 111 is provided in an end surface of the other end portion of the shaft body 10, and a second through hole 112 is provided in a circumferential surface of the shaft body 10.

Further, an annular baffle 16 is further arranged on the circumferential surface of the shaft body 10, the second threading hole is located on one side of the annular baffle 16, the water tank 14 is located on the other side of the baffle, and the end portion of the heat conduction sleeve 15 abuts against the annular baffle 16. Specifically, when the heat conductive sleeve 15 is assembled to the shaft body 10, the shaft body 10 is inserted into the heat conductive sleeve 15, and one end of the heat conductive sleeve 15 abuts against the annular baffle 16 to be positioned.

Through forming the cooling runner in the main shaft to make the direct cover of iron core of stator in the outside of main shaft, like this, the coolant liquid that flows through cooling runner in the main shaft directly cools down the stator, simultaneously, owing to need not additionally to increase the support and install the stator, make whole external diameter size reduce, make permanent magnet drum-type motor's structure compacter in order to reduce holistic volume.
