Description
Technical field
The present invention relates to magneto end cover structure, specifically a kind of full-enclosed structure electric motor end cap.
Background technology
At present, magneto has turned into an important development direction of energy-saving efficient motor.But practice have shown that, it is existing forever
Magneto is by its end cover structure is limited, and there are the following problems：First, existing magneto end cover structure lacks bearing cooling knot
Structure, causes bearing temperature rise higher, thus causes magneto design difficulty under specific temperature increase requirement big.Second, existing permanent magnetism
Motor end cap structure lacks the sealing structure between rotor fan, causes foreign matter to be easily accessible internal rotor, thus causes forever
Magneto operational reliability is poor.Third, being installed between existing magneto end cover structure and inside cap by bolt, lead
Cause installation difficulty big, thus cause the manufacturing process of magneto complicated.Based on this, it is necessary to invent a kind of brand-new Permanent Magnet and Electric
Machine end cover structure, to solve, existing magneto design difficulty under specific temperature increase requirement is big, operational reliability is poor, manufacturing process
The problem of complicated.
The content of the invention
Existing magneto design difficulty under specific temperature increase requirement is big, operational reliability is poor, system in order to solve by the present invention
A kind of the problem of making complex process, there is provided full-enclosed structure electric motor end cap.
The present invention adopts the following technical scheme that realization：
A kind of full-enclosed structure electric motor end cap, including end cap body, air duct；
Wherein, the medial surface of end cap body is anterior is provided with several preceding cylindrical bosses, and each preceding cylindrical boss edge
Circumferentially equidistant arrangement；The medial surface rear portion of end cap body is provided with several rear cylindrical bosses, and each rear cylindrical boss edge
Circumferentially equidistant arrangement；The front end face of end cap body is provided with first annular boss and the second annular boss；Second annular boss is located at
The inner side of first annular boss, and the front end face of the second annular boss is provided with labyrinth seal；The end face insertion of end cap body opens up
There are air inlet through hollow shaft hole and axial exhaust vent；Air inlet through hollow shaft hole position is in the inner side of the second annular boss；Axial exhaust vent is located at second
Between annular boss and air inlet through hollow shaft hole；The medial surface of end cap body is provided with circular orientation cotter way；
The front end face sealing of the rear end face of air duct and first annular boss is fixed, and seal bearing respectively with it is each after circle
The inner face of cylindrical end tangs is fixed；Inner face in the middle part of the lateral surface of air duct respectively with each preceding cylindrical boss is fixed；Air duct
Medial surface and end cap body lateral surface between insertion offer several counterbores；The number of counterbore and preceding cylindrical boss
Number is consistent, and each counterbore is corresponded through each preceding cylindrical boss；A fixed spiral shell has been screwed in each counterbore
Bolt.
During work, as shown in Fig. 2 the rear end face outer ring sealing of the support of the front end face outer ring of end cap body and magneto
It is fixed.The sealing of the rear end face inner ring of the front end face of air duct and the support of magneto is fixed.The front end face of second annular boss leads to
The rear end face outer ring sealing for crossing the rotor fan of labyrinth seal and magneto coordinates, while causes the rotor fan of magneto
Ventilation gap is left between end cap body.The medial surface of end cap body passes through circular orientation cotter way and the inner bearing of magneto
The lateral surface of lid is installed together.Specific work process is as follows：Under the turning effort of rotor fan, cooling wind is inhaled into axial direction
Fresh air inlet, and ventilation gap is flowed through, then discharged through axial exhaust vent.During ventilation gap is flowed through, cooling wind with forever
The bearing of magneto carries out heat exchange, thus takes away heat caused by bearing, so as to realize the circulating cooling to bearing.It is based on
Said process, compared with existing magneto end cover structure, a kind of new full-enclosed structure electric motor end cap of the present invention
By using brand new, possesses following advantage：First, the present invention is by setting up bearing cooling structure（That is air inlet through hollow shaft hole
With axial exhaust vent）, realize and circulating cooling is carried out to the bearing of magneto, thereby dramatically reduce bearing temperature rise, so as to
So that magneto design difficulty under specific temperature increase requirement greatly reduces.Second, the present invention by set up with rotor fan it
Between sealing structure（Carry the second annular boss of labyrinth seal）, realize complete between bearing cooling air duct and rotor
Isolation, thus effectively prevent foreign matter and is easily accessible internal rotor, so that magneto operational reliability is higher.Third,
No longer installed by bolt between the present invention and inside cap, but installed by circular orientation cotter way, thus shown
Work reduces installation difficulty, so that the manufacturing process of magneto is simpler.
The present invention is rational in infrastructure, ingenious in design, efficiently solves existing magneto and hardly possible is designed under specific temperature increase requirement
The problem of degree is big, operational reliability is poor, manufacturing process complexity, suitable for magneto.
