Description
Technical field
The utility model belongs to motor technology field, is related to a kind of threephase asynchronous, more particularly to a kind of stable
Type threephase asynchronous.
Background technology
Threephase motor, refers to, when the threephase stator winding of motor respectively differs 120 degree of electrical angles, be passed through three-phase alternating current
Afterwards, a rotating excitation field will be produced, the rotating excitation field cutting rotor winding, so as to produce induced-current in rotor windings, is made
The threephase asynchronous machine of motor running, the rotating speed of its rotor is less than the rotating speed of rotating excitation field, and rotor windings between magnetic field because depositing
Electromotive force and electric current are produced in relative motion, and electromagnetic torque is produced with magnetic field interaction, energy conversion is realized, with list
Phase asynchronous motor is compared, and threephase asynchronous runnability is good, and can save various materials.
Motor in life as a kind of engine convert electrical energy into mechanical energy its mainly by power transmission shaft by energy
It is transferred in working machine, both connections are typically completed by shaft coupling, the structure of current threephase asynchronous, which is mainly, determines
Rotor assembly is installed in casing, and two ends are fixed by end cap seal, and base is arranged at below casing, though this motor
Right structure is relatively easy, but operationally power transmission shaft easily trembles motor, causes the operation stability of motor poor.
The content of the invention
The purpose of this utility model is that there is provided a kind of stability is more preferable for the above-mentioned problems in the prior art
Threephase asynchronous.
The purpose of this utility model can be realized by following technical proposal：A kind of stable type threephase asynchronous, bag
Include fuselage and the power transmission shaft being arranged in fuselage, the fuselage is internally provided with rotor component, the rear end of the power transmission shaft
The fan blade of thermolysis is stretched out outside fuselage and has been fixed with, the rear end of the fuselage has been provided with protection fan blade by screw and acted on
Fan housing, it is characterised in that the front end of the fuselage is to external expansion formation and the terminal pad of its integrative-structure, before the fuselage
End, which is provided with head, described head, offers some screws, is connected between described head and fuselage by hex nut
In in terminal pad, bearing being provided with described head and power transmission shaft is passed outside head by bearing, the both sides of the head are set
The bottom for being equipped with reinforcement and reinforcement is fixed with the base of integrative-structure.
The technique effect of this stable type threephase asynchronous is：Head is fixed with the front end of fuselage, relative to tradition
Motor directly by end cap seal, can effectively reduce the vibration in the running of power transmission shaft, and head both sides are set
There is reinforcement, the base of motor is located at below head, makes head after motor installation more firm, further increase electricity
The ride comfort of motivation operation.
Further, screw is opened up on the head of this threephase asynchronous, hex nut is from the rear end of fuselage toward front end
Stretch into screw to fix head, because working machine is located in front of motor after motor installation, have impact on stretching for screwdriver
Enter, the structure can be effectively increased the space in front of nut, be more prone to the dismounting of head, the dimension in convenient motor later stage
Repair.
In above-mentioned stable type threephase asynchronous, the outer surface of the fuselage is horizontally disposed to have some rows mutually to put down
Capable radiation tooth.
In above-mentioned stable type threephase asynchronous, the side of the fuselage is provided with terminal box.
In above-mentioned stable type threephase asynchronous, mounting hole is offered on described base.
In above-mentioned stable type threephase asynchronous, the front end of the power transmission shaft is provided with flat key.
Compared with prior art, this threephase asynchronous makes it have operation more by being improved to its front-end architecture
Plus smooth-going and the more preferable advantage of stability.
