In order to solve the problems, the noise reduction fan cover for the motor provided by the utility model adopts the following technical scheme:
The noise-reducing fan cover for the motor comprises a cover body, wherein the cover body is in a cylindrical shape, the inside of the cover body is hollow, and a plurality of hollow exhaust holes are formed in the outer surface of the cover body and used for exhausting air flow brought by rotation of the motor; meanwhile, a mounting hole is formed between the exhaust holes and used for mounting a carbon brush assembly of the motor; the noise reduction flow channel is arranged in the cover body and is positioned on the inner wall of the cover body and distributed around the inner wall of the cover body.
Furthermore, the noise reduction flow passage is in a spiral structure and surrounds the inner wall of the cover body.
Further, the top of the cover body is provided with a shaft hole which is matched with a main shaft of the motor, and the main shaft of the motor penetrates through the shaft hole.
Further, the cover body below be provided with the installation boss, the inside sunken inside of installation boss be in the cover body, with the motor body matched with, the diameter is greater than the diameter of cover body top cylindricality.
Further, a plurality of clamping grooves are formed in the mounting boss, and the clamping grooves are distributed along the edge of the boss.
Further, a plurality of clamping grooves are annularly distributed at the inner circle of the installation boss, each clamping groove is in a semicircular shape, and the opening is inward.
Further, the cover body on still be provided with the winding displacement hole, the winding displacement hole be located the below of exhaust hole, run through the cover body for arrange the motor and use the electric wire.
Further, the wire arrangement holes are provided with even numbers and symmetrically distributed on two sides of the cover body.
The utility model has the beneficial effects that: according to the noise reduction fan cover for the motor, the flow direction of high-speed airflow in the sharp motor is damaged through the noise reduction flow channel, and the airflow in the traditional vortex flow direction is disturbed, so that sharp noise caused by the airflow is reduced, noise generated when the motor is used is further reduced, in addition, the assembly efficiency of the motor can be improved through improvement of the cover body structure, the clamping groove can be effectively arranged on the machine body shell, and the use of screws is reduced.
