The rotary advertisement 7 is driven by the rotary cylinder 7 by the rotary drive motor 5 of the rotary drive device, the contents of advertising or publicity is described on the outside of the rotary cylinder (7).

The most common example of a rotating advertisement 1 is a sign-ball which is widely used in this salon.

The above-described rotating advertisement 1 is described in detail with reference to FIG. 1.

The fixing cylinder 3 is fixed between the upper fixing bracket 2a and the lower fixing bracket 2b, and the fixing bracket 4 is fixed to the upper and lower sides of the fixing cylinder 3, respectively. Rotational drive motor 5 is mounted to one fixture 4.

The drive shaft of the rotary drive motor 5 described above is equipped with an electric machine element such as a gear, and is equipped with a rotary table 6 that rotates by the power of the electric machine element.

The rotating cylinder 7 is mounted to the rotating table 6 described above.

In addition, the above-described upper and lower fixing stand 4 is equipped with a central fixing stand 8, and one side of the central fixing stand 8 is provided with an illuminating means 9.

That is, when the rotary drive motor 5 is driven, it is transmitted to the rotary cylinder 7 through the electromechanical element, and eventually, the rotary cylinder 7 rotates and emits light by the lighting means 9 to obtain an advertising effect.

Hereinafter, the rotary drive motor 5 in contrast with the present invention will be described in detail with reference to the accompanying drawings.

The above-described rotary drive motor 5 is installed in the reduction gear box 10 for reducing the rotational speed of the drive motor, the stator 20 for generating the magnetic field and the stator 20, and rotated by the magnetic field as shown in FIG. Consisting of a rotor 15.

The above-described reduction gear box 10 has a motor shaft mounting hole 11 formed at one side of the bottom surface, and the other side of the reduction gear box 10 is rotated at a low speed by a gear combination in the reduction gear box 10. Is fitted.

The rotor 15 has the motor shaft 16 mounted at the center thereof, and the spline member 17 is formed at the upper end of the motor shaft 16.

The spline member 17 described above is inserted into and mounted in the motor shaft mounting hole 11 to transmit accurate rotational power of the motor without slipping.

In the stator 20, a coil is wound around the iron core, and one side of the iron core is provided with a mounting hole 21 through which the rotor 21 is inserted.

In addition, a first oil fence 13a is inserted into the reduction gear box 10 so that the rotor 15 rotates smoothly.

On the other hand, the motor shaft 16 and the lower end of the motor shaft 16a of the rotor 15 described above are made to prevent the oil from leaking or drying in the above-described first and second oil fences 13a and 13b. First and second sealing members 14a and 14b are provided.

However, the above-described conventional rotational drive motor 5 is pointed out the following problems.

Due to its characteristics, the rotating advertisement 1 is naturally operated during operation, and it is a common example to operate it even during non-operation hours, especially at midnight hours, and operates 24 hours with almost no time off.

It is the first and second oil fences 13a and 13b for the rotor 15 to smoothly rotate, but the heat in the rotary drive motor 5 in accordance with the continuous movement of the rotating advertisement 1 is maintained. This heat is generated and the gap causes the first and second sealing members 14a and 14b to expand.

That is, the oil in the first and second oil fences 13a and 13b is lost due to evaporation, leakage, or the like as the rotary type mineral material 1 is operated for a long time. The fences 13a and 13b easily reach the point where they cannot play a normal role.

In particular, due to the abnormal role of the first and second oil fences 13a and 13b described above, it is pointed out that the rotor 15 is prevented from smoothly rotating, noise starts to occur, and vibration occurs.

On the other hand, the first and second oil fences 13a and 13b are one of the consumables, but their lifespan is significantly shorter than other accessories, but only the first and second oil fences 13a and 13b are A.
