Description
Technical Field
The utility model relates to the technical field of motors, concretely relates to air pump motor of anti-oxidant low noise.
Background
The electric air pump is an air pump taking electric power as power, air is continuously compressed through the electric power to generate air pressure, and the air pump motor can vibrate in the working process to cause noise pollution.
Air pump motor among prior art is generally direct to be connected through pressing seat direct fit with stone abrasive disc, aluminium at air pump motor rear end, and such setting lets the aluminium in the aluminium pressure seat, air, the graphite chemical composition mix easily, uses for a long time to cause the motor inside, aluminium pressure seat to go mildy easily, influences the life of air pump motor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough to above-mentioned prior art provides an air pump motor of anti-oxidant low noise, effectively reduces the noise that the air pump motor produced in the course of the work, prevents effectively that the inside moldy dead phenomenon of pivot card from appearing of air pump motor.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an air pump motor of anti-oxidant low noise, includes motor housing, rotor, end cover, the rotor sets up in motor housing, is connected with the output shaft on the rotor, the output shaft passes the end cover center, the end cover passes through bolted connection, its characterized in that with motor housing: the end cover is provided with an annular mounting groove, the mounting groove is in a step shape, the mounting groove is sequentially provided with a sealing ring, a bearing and a wear-resistant stainless steel gasket from inside to outside, an annular groove is formed in the motor shell, and a damping and noise-reducing ring is inserted into the annular groove.
The utility model has the characteristics as above: the stainless steel wear-resistant gasket is arranged at the outward end of the annular mounting groove and is arranged between the motor and the pump body which is externally connected, when the air pump motor is integrally assembled, the motor is prevented from being in direct contact with a graphite sheet, the wear resistance and the anti-oxidation effect of the motor can be improved, the sealing ring is arranged at the inward end of the annular mounting groove, impurities can be prevented from entering the motor, the inner part of the air pump motor is effectively prevented from mildewing, and the phenomenon that a rotating shaft is blocked is avoided, so that the service life of the motor is prolonged; set up vibration/noise reduction ring in motor housing, 360 absorbed noise of annular vibration/noise reduction ring, noise reduction effect doubles.
The utility model discloses further setting is: the vibration and noise reduction ring is an aluminum honeycomb perforated sound absorption plate.
