Embodiment Construction
[0007] refer to Figure 1-2 , the specific embodiment adopts the following technical scheme: it is made up of casing 1, steel ball 2, bearing chamber 3 and hemispherical cavity 4, and the bottom of casing 1 is provided with bearing chamber 3, and the bottom of bearing chamber 3 is provided with hemispherical cavity 4. The steel ball 2 is tightly embedded in the hemispherical cavity 4 .
[0008] This specific embodiment can change the contact of the motor rotor shaft head from surface contact to point contact, avoiding the motor noise caused by the direct contact between the motor rotor shaft head and the casing when the motor is working, and effectively reducing the noise source of the motor. The service life of the motor is increased, and the electrical performance of the motor is improved.

The invention provides a casing embedding steel ball part structure for a motor, relating to a casing embedding steel ball part structure for a motor. The structure consists of a casing (1), a steel ball (2), a bearing chamber (3) and a semi-spherical cavity (4), wherein the bearing chamber (3) is arranged on the bottom of the casing (1); the semi-spherical cavity (4) is arranged on the bottom of the bearing chamber (3); and the steel ball (2) is closely embedded inside the semi-spherical cavity (4). The casing embedding steel ball part structure ensures that the rotor shaft head contact of the motor is changed from surface contact to point contact, so that motor noise generated by the large-area direct contact of the rotor shaft head of the motor and the casing when the motor runs can be avoided, the noise source of the motor is effectively reduced, the service life of the motor is improved, and the electrical performance of the motor is improved.
Description
Technical field: [0001] The invention relates to a steel ball component structure embedded in a motor case. Background technique: [0002] People's daily life and production are inseparable from electric motors. The contact of the motor rotor shaft head in the prior art is surface contact, so when the motor is working, the direct contact between the motor rotor shaft head and the casing will generate a lot of motor noise, which will affect the service life of the motor, and the motor with this structure Poor electrical performance. Invention content: [0003] The purpose of the present invention is to provide a motor casing inlaid steel ball component structure, which can change the contact of the motor rotor shaft head from surface contact to point contact, and avoid the large-area contact between the motor rotor shaft head and the casing when the motor is working. The generated motor noise effectively reduces the noise source of the motor, increases the service life of...
