Description

Motor noise processing device

Technical Field

The utility model belongs to the technical field of the noise processing device, concretely relates to motor noise processing apparatus.

Background

Motor noise is mainly caused by the rotor and bearings. The bearing is a connection member of a rotor and a stator of a motor, which receives excitation of various forces in the motor and transmits the excitation force, thereby generating vibration and noise. Mechanical noise can also be generated by the brushes of the machine rubbing against the slip rings or commutator. For motors with higher rotational speeds or longer rotors, dynamic balance correction is performed. The bearing of the motor adopts a low-noise bearing special for the motor, when the motor runs, the inner ring and the outer ring of the bearing should not slide harmfully, but the bearing and the shaft or the bearing and the end cover bearing chamber should be prevented from being matched too tightly, so that the small radial play of the bearing and the deformation of the inner ring and the outer ring of the bearing are avoided, and the processing precision and the surface finish of the bearing baffle of the rotor shaft and the end cover bearing chamber are high. However, the noise processing device of the motor is mainly used for silencing the inside of the motor, the decibel value of the noise generated by the motor is still higher, and the noise of the motor can be reduced only by depending on frequent maintenance of the motor.
