In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 3(a) and 3(b), an embodiment of the present invention provides a motor bearing support assembly, including:

a ball bearing 100; and

a motor bracket 200 having a bracket bearing chamber 300 therein; and

and an elastic member 400 installed in the holder bearing chamber 300 and coupled to the ball bearing 100.

In this embodiment, the elastic member 400 is installed in the bracket bearing chamber 300, so that it can be directly matched with the ball bearing 100, thereby indirectly enabling the ball bearing 100 and the motor bracket 200 to still realize stable matching, in contrast, only the corresponding bracket bearing chamber 300 needs to be arranged in the motor bracket 200, and the matching between the ball bearing 100 and the bracket can be realized without additionally processing the bracket, therefore, compared with the conventional technology, the utility model discloses the processing precision requirement of the motor bracket 200 can be reduced, the process cost is saved, and the production is more facilitated; and, the friction noise caused by the direct matching of the ball bearing 100 and the motor bracket 200 is avoided, the noise reduction effect is achieved for the motor, and the motor is more environment-friendly and reliable. Therefore, the utility model relates to a rationally, the structure is simple and convenient, can reduce motor support 200's machining precision requirement, does benefit to production, has noise reduction effect to the motor simultaneously, makes the more environmental protection of motor reliable.

Further, the elastic member 400 is an elastic steel ring. Specifically, the steel ring can be well matched with the appearance structure of the ball bearing 100, and the steel ring is made of a steel material, so that the steel ring is good in toughness and has a good installation effect.

Further, referring to fig. 2, the elastic steel ring designed by the inventor is provided with a plurality of protrusions 410 on the inner ring, and the plurality of protrusions 410 are in matching abutment with the outer ring of the ball bearing 100.

In this embodiment, the plurality of protrusions 410 are just abutted against the outer ring of the ball bearing 100, so that the ball bearing 100 can be stably fixed, and the indirect connection between the ball bearing 100 and the motor bracket 200 is realized; moreover, the protrusion 410 increases the mass of the elastic steel ring itself, so that the stability of the elastic steel ring is improved when the elastic steel ring is connected with the ball bearing 100.

Further, referring to fig. 2, the protrusions 410 are arranged at equal intervals along the inner ring of the elastic steel ring. Specifically, according to the mechanical principle, the arrangement makes the elastic force provided by each protrusion 410 when being connected with the outer ring of the ball bearing 100 be substantially the same, so as to ensure that the stress at each position where the elastic steel ring is connected with the ball bearing 100 is uniform, and prevent the situation that the elastic steel ring or the ball bearing 100 is damaged due to the influence of overpressure or underpressure caused by unbalanced stress at one position.

Further, the elastic member 400 is coupled with the holder bearing housing 300 in an interference fit manner. Specifically, a stable elastic pressure is generated between the elastic member 400 and the bracket bearing chamber 300, so that the elastic member 400 and the bracket bearing chamber are stably connected, and the installation stability of the elastic member 400 is ensured, so that the elastic member has a better effect when being installed with the ball bearing 100.
