Abstract
The utility model relates to a structure of a steel ball part embedded in a motor casing, which 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 at the bottom part of the casing (1), the semi-spherical cavity (4) is formed at the bottom part of the bearing chamber (3), and the steel ball (2) is tightly embedded in the semi-spherical cavity (4). The structure can change the contact of a shaft head of a motor rotor to point contact from surface contact, thereby avoiding the noise of the motor produced by large-area direct contact between the shaft head of the motor rotor and the casing when a motor works, effectively reducing a noise source of the motor, prolonging the service life of the motor and improving the electrical performance of the motor.
Description
Technical field:
The utility model relates to a kind of motor case and inlays the steel ball modular construction.
Background technology:
Daily life, production all be unable to do without motor.The contact of the rotor spindle nose of prior art is the face contact, so directly contact the very big noise of motor of meeting generation with the casing large tracts of land because of the rotor spindle nose during machine operation, influences the useful life of motor, and adopts the motor electric property of this structure poor.
The utility model content:
The purpose of this utility model provides a kind of motor case and inlays the steel ball modular construction, it can make the contact of rotor spindle nose by face contact changing into a contact, directly contact the noise of motor that produces because of the rotor spindle nose when having avoided machine operation with the casing large tracts of land, effectively reduced the noise source of motor, improve the useful life of motor, improved the electric property of motor.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of casing 1, steel ball 2, bearing chamber 3 and hemisphere die cavity 4, casing 1 bottom is provided with bearing chamber 3, bearing chamber 3 bottoms are provided with hemisphere die cavity 4, and steel ball 2 is embedded in hemisphere die cavity 4 inside closely.
The utility model can make the contact of rotor spindle nose by face contact changing into a contact, directly contact the noise of motor that produces because of the rotor spindle nose when having avoided machine operation with the casing large tracts of land, effectively reduced the noise source of motor, improve the useful life of motor, improved the electric property of motor.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment:
With reference to Fig. 1-2, this embodiment is by the following technical solutions: it is made up of casing 1, steel ball 2, bearing chamber 3 and hemisphere die cavity 4, casing 1 bottom is provided with bearing chamber 3, and bearing chamber 3 bottoms are provided with hemisphere die cavity 4, and steel ball 2 is embedded in hemisphere die cavity 4 inside closely.
This embodiment can make the contact of rotor spindle nose by face contact changing into a contact, directly contact the noise of motor that produces because of the rotor spindle nose when having avoided machine operation with the casing large tracts of land, effectively reduced the noise source of motor, improve the useful life of motor, improved the electric property of motor.
