Abstract
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:
The present invention relates to a kind of motor case and inlay 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.
Summary of the invention:
The purpose of this invention is to provide a kind of motor case and inlay 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 present invention 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 present invention 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 invention, 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.
