Description
Technical Field
The utility model belongs to the technical field of the disk motor technique and specifically relates to a built-in radiating no iron core disk motor.
Background
The applicant discloses a built-in heat dissipation coreless disk type motor in the previously applied chinese utility model patent with publication number CN208209735U, but in practical application, because the circulating air circulates in the motor, when the temperature rises, the internal pressure of the motor increases, the pressure to the sealing ring increases, so that the sealing ring is often ejected or damaged, and the heat dissipation effect of the motor by the internal circulation mode is not obvious.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to the not enough among the prior art, provide a built-in radiating no iron core disk motor. In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the rotor part is arranged on the rotating shaft, a circulating air channel is arranged inside the casing, a first centrifugal blade for internal air circulation in the circulating air channel is arranged on the rotor part, the rotating shaft is a hollow shaft and comprises a rotor internal circulation hole and an external circulation hole, a second centrifugal blade is arranged on the shaft diameter of the external circulation hole and located in a second cavity inside the casing, an air outlet for air outlet is arranged on the side face of the second cavity, and a plug for sealing is arranged on a center hole of one end, close to the external circulation hole, of the rotating shaft.
The motor has the advantages that through the rotation of the second centrifugal blade, hot air circulating inside the motor enters the second cavity through the external circulation hole of the rotating shaft, and when the hot air is discharged through the air outlet, cold air outside enters the motor to dissipate heat of the motor.
In the above scheme, preferably, an air filter is arranged on a central hole at one end of the rotating shaft without the plug, and a protection piece is arranged on the air outlet.
In the above scheme, preferably, the air filter is an air filter screen, and a ventilation sand and sand protective cap is arranged outside.
The rotary shaft air filter has the beneficial effects that air entering the rotary shaft is filtered, and insects or silt are prevented from entering the rotary shaft.
In the above scheme, preferably, the protection piece is a ventilation sand protection cap and is provided with an insect prevention gauze.
Its beneficial effect lies in, prevents that worm or silt from entering into in the second chamber.
In the above scheme, preferably, the external circulation holes are provided with a plurality of holes, and the external circulation holes and the air inlet holes on the second centrifugal blades are arranged in a staggered manner.
The centrifugal fan has the advantages that hot air which is exhausted from the internal circulation air channel of the shell can enter the second cavity through the external circulation hole, and then the second centrifugal blade is driven by the rotating shaft to be exhausted to the outside of the motor.
The utility model has the advantages that: the utility model discloses the innovation has designed a built-in radiating no iron core disk motor, makes the motor at the in-process of operation, and there is outside air to enter into the motor inside continuous for the motor obtains better heat dissipation, and keeps the inside and outside pressure of motor the same always, makes the sealing member of motor be difficult to suffer destruction, promotes the stability of motor.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1-3, a built-in heat dissipation coreless disk motor includes a rotating shaft 1, a rotor portion 3 and a housing 2, the rotor portion 3 is disposed on the rotating shaft 1, the rotor portion 3 is disposed in the housing 2, a circulation air duct is disposed inside the housing 2, a first centrifugal blade 6 is disposed on the rotor portion 3, the rotating shaft 1 is a hollow shaft, the rotating shaft 1 includes a rotor internal circulation hole 11 and an external circulation hole 12, wherein air enters the rotating shaft 1 from the outside through a central hole, enters the circulation air duct from the internal circulation hole 11, flows in the circulation air duct through the first centrifugal blade 6 to take away heat inside the motor, and enters the central hole of the rotating shaft 1 through the internal circulation hole 11 after circulating for one turn.
The shaft diameter of the external circulation hole 12 is provided with a plurality of second centrifugal blades 7, and the second centrifugal blades are positioned in a second chamber 22 inside the casing 2, and the external circulation hole 12 is arranged in a staggered manner with the air inlet holes on the second centrifugal blades 7, so that when the rotating shaft 1 drives the second centrifugal blades 7 to rotate, the heated air which is completely circulated inside the central hole of the rotating shaft 1 can enter the second chamber 22 from the external circulation hole 12, and then is discharged from an air outlet 23 on the side surface of the second chamber 22.
A plug 4 for sealing is arranged on the central hole of one end of the rotating shaft 1 close to the external circulation hole 12, so that the hot air in the central hole of the rotating shaft 1 can only enter the second chamber 22 from the external circulation hole 12 and then is discharged.
Second centrifugal blade 7 is discharging hot-air to the outside back of motor, and the inside negative pressure that forms of motor for the air of outside does not have the one end of end cap 4 through pivot 1 and enters into in the pivot 1 centre bore, carries out next round and adsorbs heat energy then exhaust process again, and the motor rotates always, and this process moves always, makes the temperature of motor obtain effectual control, and inside and outside pressure is the same makes the sealing member can not destroyed or pop out.
The rotating shaft 1 is provided with an air filter 8 on the center hole of one end without the plug 4, the air filter is an air filter screen in the embodiment, and a ventilation silt protective cap is arranged outside the rotating shaft, so that sundries in the outside air can not enter the motor.
A guard 9, in this embodiment a sand guard with a gauze, is provided at the outlet 23 so that insects or sand cannot enter the second chamber through the outlet 23.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
