TECHNICAL AREA

The invention is related to the sound insulation of the electromagnetic elevator motor brake, which provides the prevention of noise pollution that will occur by reducing the mechanical metal impact sound that occurs during the operation of the electromagnetic motor brake used in elevator drive motors.

PRIOR ART

Especially the gearless system used in elevator systems, electromagnetic braking systems are used extensively today for the braking of gearless elevator drive motors. The brake system on the elevator drive motor consists of the coil body, which contains the coils that create a magnetic field, and the axial rotor, which is positioned between the body and the brake disc and brake pad. During the operation of the elevator drive motor, the axial rotor is pulled towards the coil body by the electromagnetic effect created by the electric current passing through the coils in the brake system, and the brake disc with the pad is discharged and the brake is released. By stopping the drive motor, the current passing through the coils is interrupted and the electromagnetic attraction on the axial rotor is eliminated. Thus, braking occurs when the springs between the coil body and the axial rotor are released and the axial rotor moves the lining on the motor.

In the current technique of the elevator motor brakes used, the electromagnetic effect is obtained through the coil windings, while the coil windings are carried out on circular bodies. When the previous GB2236623A and WO2006136246A1 documents are examined, it was understood that electromagnetic fields with single or multiple coil bodies are tried to be created. As can be seen in the documents, coil winding surfaces generally contain circular continuous-form surfaces, the bodies in which the coils are placed are selected to have circular or angular continuous edges. During the operation of the elevator drive motor brake, the metal crashing sound occurs with the contact of the rotor surface with the connection bushings during the movement of the axial rotor part, which is activated by the electromagnetic effect and spring pressure through the centering shaft to the elevator drive motor. This situation creates noise pollution during engine brake operation and causes deformation on the material with the impact effect.

BRIEF DESCRIPTION OF THE INVENTION

The electromagnetic elevator motor brake sound insulation, which is the subject of the invention, has been developed to both eliminate noise pollution and prevent material deformation by reducing the mechanical metal impact sound that occurs during the operation of the electromagnetic elevator motor brake used in elevator drive motors.

In the sound insulation of the developed electromagnetic elevator motor brake, the loud noise that will arise during braking from the contact of the rotor (4) with the connecting bush (5) during the movement of the axial rotor (4) on the centering shaft (7) between the coil body (3) and the cover plate (2) on the motor (1 ) is prevented by the insulation material (6) positioned between the axial rotor (4) and the connecting bush (5). Thus, while the high noise pollution that will occur during braking is eliminated, at the same time the material deformations are prevented.

DETAILED DESCRIPTION OF THE INVENTION

Electromagnetic elevator motor brake sound insulation was developed to eliminate the noise and material deformation caused during the braking of the elevator drive motor; during the electromagnetic braking of the elevator drive motor (1 ), the magnetic effect on the centering shaft (7) between the coil body (3) and the cover plate (2) which moves bi-directionally with the magnetic effect and spring pressure towards the cover plate (2) between the axial rotor (4) and the connecting bush (5) to reduce the noise that will arise during its movement, again on the centering shaft (7) and during its contact with the connecting bush (5) located between the cover plate (2) and the axial rotor (4) it is positioned at least one insulation material (6).

The subject of the invention is the insulation material (6) developed in the electromagnetic elevator motor brake sound insulation), preferably a part made of rubber, silicone, or plastic material.

The subject of the invention is the insulation material (6) developed in electromagnetic elevator motor brake sound insulation, preferably a part manufactured in circular or angular form.

In the electromagnetic elevator motor brake which is the subject of the invention, the movement of the axial rotor (4) from the coil body (3) to the cover plate (2) during electromagnetic braking takes place sharply with the elimination of the electromagnetic effect and spring pressure. Thanks to the developed insulation material (6), the contact of the axial rotor (4) to the connection bushing (5) during its movement towards the cover plate (2) are realized through the insulation material (6). Thus, the loud noise that may occur during the contact of the axial rotor (4) with the connecting bushing (5) is prevented and the deformation of the material based on the contact is prevented. In this way, both noise pollution is eliminated and the service life of the product is extended.
