Description

Technical Field

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

[0002] The motor is an important device for converting electrical energy into mechanical energy and is indispensable in modern society. It operates based on the principle of electromagnetic induction. When the stator winding is energized, a rotating magnetic field is generated, which acts on the rotor, causing the rotor to rotate due to electromagnetic force, thereby converting electrical energy into mechanical energy for output power. The application of motors is very extensive. Machine tools, fans, pumps and other equipment in industrial production, electric vehicles and electric trains in the field of transportation, and household appliances in daily life all rely on motors.

[0003] When the shaft rotates, the shaft can only rotate stably in the motor if the two ends of the shaft have a good auxiliary rotation effect. However, the auxiliary rotating component at the rear end of the shaft is located inside the hood, and there are many difficulties and inconveniences in adding lubrication to the internal auxiliary support mechanism. For this reason, after the shaft is used for a long time, the auxiliary rotating mechanism at the rear end will become unstable in its support for rotation due to lack of lubrication. Utility Model Content

[0004] In order to overcome the above defects of the prior art, a stable motor shaft is provided to solve the problems raised in the above background technology.

[0008] Through the above technical solution, when the shaft starts to rotate, the support roller in the slot can support the rotation of the rear end of the shaft, thereby keeping the rotation of the shaft stable. At the same time, by arranging the ball inside the shaft and using the limit groove in the sealing plate to support the rotation of the ball, the rotation of the front end of the shaft can be stabilized. When the shaft rotates at high speed, a small amount of lubricating oil will be thrown out through the flow limiting orifice plate to continuously lubricate the rotating part of the support roller.

[0012] Through the above technical solution, the rotation of the shaft drives the blades to rotate to blow away the dust that may float into the connection, which can effectively prevent the accumulation of dust at the connection between the shaft and the sealing plate. The sealing cover can prevent the remaining oil in the oil guide groove from being thrown out.

[0013] Furthermore, a dust cover is installed on one side of the sealing plate, and a dust net is fixedly arranged inside the dust cover;

[0014] Through the above technical solution, a dust cover with a dust net is arranged on the sealing plate, so that dust can only enter from the dust net, thereby reducing the amount of dust entering the connection.

[0016] Through the above technical solution, the stator is fixed, the rotor is located inside the stator, and an appropriate air gap is maintained between the two. Electromagnetically, the stator generates a rotating magnetic field, which interacts with the rotor to cause the rotor to rotate.

[0018] Through the above technical solution, a wire is provided to supply power to the device.

[0019] Furthermore, a plurality of first key slots are provided in the rotor, a plurality of second key slots are provided in the shaft, and a key is clamped in each of the second key slots;

[0020] Through the above technical solution, the key can be used to connect the first keyway and the second keyway, so that the power of the rotor is transmitted to the rotating shaft.

[0021] Technical effects and advantages of the utility model:

[0022] 1. The stable motor shaft proposed by the utility model, when the shaft starts to rotate, the support roller in the slot can support the rotation of the rear end of the shaft, so that the rotation of the shaft remains stable.

When the shaft rotates at high speed, a small amount of lubricating oil will be thrown out through the flow limiting orifice plate to continuously lubricate the rotating part of the support roller, thereby solving the problem of unstable support of the support roller due to the lack of good lubrication during long-term use.

[0023] 2. The utility model proposes a stable motor shaft, on which blades are arranged.

[0034] In some embodiments, according to Figure 1-6As shown, a hood 11 is fixedly provided on one side of the slot 6, and the hood 11 is fixedly connected to the sealing plate 9 by a plurality of bolts, and the bolts can conveniently connect the hood 11 and the sealing plate 9, a plurality of blades 12 are fixedly provided on the rotating shaft 1, and a sealing cover 13 is clamped on the oil guide groove 2, and the rotation of the rotating shaft 1 drives the blades 12 to rotate to blow away the dust that may float into the connection, which can effectively prevent the accumulation of dust at the connection between the rotating shaft 1 and the sealing plate 9, and the setting of the sealing cover 13 can prevent the remaining oil in the oil guide groove 2 from being thrown out, and a dust cover 14 is installed on one side of the sealing plate 9, and a dust net 15 is fixedly provided in the dust cover 14, and a dust cover 14 with a dust net 15 is provided on the sealing plate 9, so that the dust can only be blown out from the dust net 15. The hood 11 is provided with a rotor 16 for rotation, and two stators 17 are fixedly provided in the hood 11. The stator 17 is fixed, and the rotor 16 is located in the stator. The two maintain an appropriate air gap. Electromagnetically, the stator 17 generates a rotating magnetic field, which interacts with the rotor 16 to rotate the rotor 16. Two wires 18 are connected in the hood 11, and the wires 18 can be provided to power the device. A plurality of first key slots 19 are provided in the rotor 16, and a plurality of second key slots 20 are provided in the rotating shaft 1.

[0035] Working principle of the utility model: when using the utility model, it is only necessary to put the rotating shaft 1 into the machine cover 11, and then install the sealing plate 9 to use it. When the rotating shaft 1 rotates, the supporting roller 7 in the card slot 6 can support the rotation of the rear end of the rotating shaft 1, so that the rotation of the rotating shaft 1 is stable. By arranging the ball 8 in the rotating shaft 1 and making the limiting groove 10 in the sealing plate 9 support the rotation of the ball 8, the rotation of the front end of the rotating shaft 1 can be stabilized. Since the supporting roller 7 is inside the machine cover 11, it is inconvenient to lubricate the supporting roller 7, which causes the rotating shaft 1 to rotate unsteadily after long-term use. Therefore, an oil guide groove 2 is opened in the rotating shaft 1. By adding oil to the oil guide groove 2, the oil can flow through the one-way valve 3 and then enter the oil storage tank 4 for storage. When the shaft 1 rotates at high speed, a small amount of oil will be thrown out through the flow limiting orifice 5 and continue to lubricate the rotating part of the support roller 7, which solves the problem of unstable support of the support roller 7 due to lack of good lubrication after long-term use. When working in a dusty environment, dust will drill into the connection between the shaft 1 and the sealing plate 9. Therefore, a blade 12 is arranged on the shaft 1. The rotation of the shaft 1 can drive the blade 12 to rotate, and the dust that may float into the connection between the shaft 1 and the sealing plate 9 is blown away, and a dust cover 14 is arranged on the sealing plate 9, and a dust net 15 is arranged on the dust cover 14. This makes it possible for dust to enter only from the dust net 15, and the blowing of the blade 12 can well resist dust, thereby ensuring the smooth rotation of the shaft 1.
