Description

Technical Field

[0001] The utility model relates to the technical field of motors, and more specifically, to a motor shaft with a forced cooling device. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, and the shaft is a necessary component for outputting its power. A motor is generally composed of a rotor, a stator, a shaft, a cooling fan and a casing. The rotor will generate a lot of heat during rotation, and the heat generated is mainly dissipated through the cooling fan and the casing. This heat dissipation method has a better heat dissipation effect on the surface of the motor, but it is difficult to dissipate the heat generated by the high-heat generating components inside the motor, such as the rotor and the shaft.

[0003] The utility model patent with patent announcement number CN219018623U discloses a motor shaft with a forced cooling device, including a motor body, an output shaft connected to the right side of the motor body, a cooling member arranged on the outer surface of the output shaft, sealed bearings fixed to both ends of the cooling member, a fixing plate arranged on the lower surface of the motor body, a mounting box arranged on the lower surface of the fixing plate, a liquid extraction pipe connected to the right side of the mounting box, a pump blade fixed to the outer wall of the output shaft, a heat absorbing member arranged on the left side of the pump blade, a plurality of heat conducting holes arranged equidistantly inside the heat absorbing member, and a liquid filling port arranged on the left side of the mounting box. The utility model uses the liquid extraction pipe to drive the pump blade to rotate when the output shaft rotates, thereby drawing the coolant in the mounting box into the cooling member. With the cooperation of the heat absorbing member, the output shaft can be forced to cool, which can effectively reduce the situation where the output shaft is overheated.

[0004] However, in actual use, this structure can only cool a portion of the shaft, but cannot cool the entire shaft, resulting in a low cooling effect. Therefore, a motor shaft with a forced cooling device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

A first filter plate 9, a first fan blade 10 is installed on the rotating shaft body 4 outside the first filter plate 9, a second filter plate 11 is installed inside the rear end of the motor body 3, a second fan blade 12 is installed on the rotating shaft body 4 outside the second filter plate 11, a mounting groove is opened at one end of the rotating shaft body 4, the shaft seal and the connecting block 13 are both arranged in the mounting groove, a partition plate 14 is arranged inside the rotating shaft body 4, a first channel 15 and a second channel 16 are arranged on both sides of the partition plate 14, and the first channel 15 and the second channel 16 are connected.

[0024] In a specific implementation, cold water is introduced from the water inlet pipe 6 into the first channel 15 or the second channel 16 separated and connected by the partition plate 14 inside the shaft body 4, so that the cold water can be transported from one end of the shaft body 4 to the other end of the shaft body 4, and when the motor body 3 is running, the cold water is stirred in the shaft body 4, so that forced cooling can be performed and the uniformity of cooling can be improved. The cold water after absorbing heat is continuously discharged from the drain pipe 7 under the action of water pressure, so that cold water can be continuously transported to the inside of the shaft body 4 for forced cooling, thereby improving the cooling effect. In the process of transporting the cold water, During the process, the temperature around one end of the rotating shaft body 4 connected to the water inlet pipe 6 is relatively low.

Two brackets are provided on the bracket 805. The drain pipe 7 and the water inlet pipe 6 are respectively crimped in the corresponding brackets.

[0026] During specific implementation, by loosening the locking sleeve 804, the extension rod 803 can be extended and retracted in the sleeve 802, so that the height of the bracket 805 can be adjusted, so that the bracket 805 can support the water inlet pipe 6 and the drain pipe 7 at the same time, thereby avoiding twisting of the hose connecting the water inlet pipe 6 and the drain pipe 7, thereby improving the stability of water delivery.
