Abstract

The utility model discloses a kind of motor noise-reducing cover boards, include a circular substrate, the center of the substrate is equipped with the axle sleeve of an annular, the lateral wall of the substrate is equipped with several flange connectors, a flange hole is respectively equipped on the flange connector, the second noise reduction groove array that the inner wall of the substrate is made of equipped with a first noise reduction groove array being made of the first noise reduction groove and one the second noise reduction groove, the first noise reduction groove array and the second noise reduction groove array is arranged in the circumferential direction of the axle sleeve, the first noise reduction groove and the second noise reduction groove is hexagonal, the distribution density of the second noise reduction groove is greater than the first noise reduction groove.The motor noise-reducing cover board of the utility model has the advantage that when rotor high-speed rotation, the air-flow of rotation is directly impinging on the first noise reduction groove and the second noise reduction groove, significantly the noise reduction rotation noise of motor, is particularly suitable for high-speed motor.

Description

Noise reduction cover plate of motor

Technical Field

The utility model relates to a motor, more precisely, be a motor noise reduction apron.

Background

When the motor runs, especially a high-speed permanent magnet motor, huge noise can be generated, and the use comfort is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve the technical problem that prior art exists to a apron of making an uproar falls in motor is provided.

The above technical problem of the present invention can be solved by the following technical solutions:

the utility model provides an apron of making an uproar falls in motor, its characterized in that, the apron of making an uproar falls in motor contain a circular shape base plate, the center of base plate be equipped with an annular axle sleeve, the lateral wall of base plate on be equipped with a plurality of connecting flanges, connecting flange on be equipped with a flange through-hole respectively, the inner wall of base plate on be equipped with one by the first recess array of making an uproar and fall the recess array of making an uproar by the second that the recess of making an uproar constitutes of making an uproar fall in the first recess array of making an uproar and the second of making an uproar fall the recess array of making an uproar and all set up in circumference of axle sleeve, the first recess of making an uproar and the second.

As the preferred embodiment of the present invention, the second noise reduction groove has a distribution density greater than that of the first noise reduction groove.

The utility model discloses an apron of making an uproar falls in motor has following advantage: when the motor rotor rotates at a high speed, the rotating airflow directly impacts the first noise reduction groove and the second noise reduction groove, so that the rotating noise of the motor is greatly reduced, and the motor rotor is particularly suitable for a high-speed motor. The noise reduction cover plate for the motor is simple in structure, obvious in effect, low in cost and high in practicability.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic perspective view of a noise reduction cover plate of a motor according to the present invention;

FIG. 2 is an enlarged detail view of the area A of the noise reduction cover plate of the motor in FIG. 1;

wherein,

1. a motor noise reduction cover plate; 2. a substrate; 3. a shaft sleeve; 4. a connecting flange; 5. a flange through hole; 6. a first noise reduction groove; 7. and a second noise reduction groove.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

As shown in fig. 1 to 2, the noise reduction cover plate 1 for a motor includes a circular base plate 2, an annular shaft sleeve 3 is disposed at the center of the base plate 2, a plurality of connecting flanges 4 are disposed on the outer side wall of the base plate 2, a flange through hole 5 is disposed on each of the connecting flanges 4, a first noise reduction groove array formed by first noise reduction grooves 6 and a second noise reduction groove array formed by second noise reduction grooves 7 are disposed on the inner wall of the base plate 2, the first noise reduction groove array and the second noise reduction groove array are both disposed in the circumferential direction of the shaft sleeve 3, and the first noise reduction grooves 6 and the second noise reduction grooves 7 are both hexagonal.

The distribution density of the second noise reduction grooves 7 is greater than that of the first noise reduction grooves 6.

When the motor rotor rotates at a high speed, the rotating airflow directly impacts the first noise reduction groove 6 and the second noise reduction groove 7, so that the rotating noise of the motor is greatly reduced, and the motor rotor is particularly suitable for a high-speed motor.

The noise reduction cover plate for the motor is simple in structure, obvious in effect, low in cost and high in practicability.

Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
