Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is simple to is well understood to this
Bright, but they do not constitute restriction to the present invention.
As shown in Figure 1 and Figure 2, the present invention includes rotating shaft 1, end cap disk 2, pole shoe 10, magnetic fat 11 and permanent magnet 12, described turn
Axle 1 is through end cap disk 2, and described pole shoe 10 is positioned at end cap disk 2 side and is circumferentially arranged at rotating shaft 1 surface, and magnetic fat 11 is arranged at
Between pole shoe 10 and rotating shaft 1 surface, it is internal that described permanent magnet 12 is arranged at pole shoe 10, and described end cap disk 2 side is fixed with annular
Shower 6, fill cooling medium 9 in shower 6, described shower 6 and pole shoe 10 are positioned at the same side of end cap disk 2, described
Shower 6 is arranged around described rotating shaft 1, is circumferentially interval with multiple spray with pole shoe correspondence position inside described shower 6
8, the outlet alignment pole shoe 10 of described spray head 8, cooling medium 9 uniformly spray by shower 6, spray head 8 and covers in pole
On boots 10, take away the heat that magnetic fat 11 is delivered on pole shoe 10 in time, and then reduce magnetic fat running temperature.
In such scheme, end cap disk 2 is interval with multiple bearings 4 along shaft circumference, a bearing 4 is installed clip 5,
Described shower 6 is fixed in end cap disk 2 by multiple clips 5, arranges fixing seat 7, in order to fixed showerhead inside shower 2
8。
In such scheme, one end of shower 6 is provided with cooling medium entrance 14, the other end passes through silently 13 plug for seal,
Shower 6 arranges one end of cooling medium entrance and is positioned at bottom rotating shaft 1, cooling medium spray can be made to produce in shower certain
Pressure, cooling medium ejects aerosol fan shape from spray head, take away in time magnetic fat produce heat,
In such scheme, cooling medium 9 is the liquid that boiling point is less than 50 DEG C at ambient pressure.Cooling medium 9 preferentially selects boiling
The liquid that point is relatively low, can take away the heat that magnetic fat produces in time, improves the radiating efficiency of pole shoe.
Rotating shaft 1 of the present invention, end cap disk 2, pole shoe 10, magnetic fat 11, permanent magnet 12 constitute magnetic fat sealing device, and end cap disk 2 is
Whole magnetic fat sealing device provides to install and supports, and permanent magnet 12 is between pole shoe 10, and magnetic fat 11 is inhaled under permanent magnet 12 acts on
It is attached between rotating shaft 1 and pole shoe 10, when, in rotating shaft 1 rotation process, between magnetic fat 11 and rotating shaft 1, pole shoe 10, friction can produce heat
Measure and be delivered on pole shoe 10.Propping up bearing 4 be positioned at outside pole shoe 10 and be fixed in end cap disk 2, shower 6 is arranged on support seat
On 4, and fastened by clip 5 and screw 3, prevent shower 6 from coming off.Cooling, with silently 13 blockings, is so worked as in shower one end
Medium 9 can produce certain pressure after the cooling medium entrance 14 of shower 6 other end enters in shower 6, is conducive to
Cooling medium 9 is ejected into pole shoe 10 from spray head 8 with aerosol fan shape, can improve pole shoe 10 radiating rate, and spray head 8 passes through
Fixing seat 7 is uniformly arranged on shower 6, can make cooling medium 9 by being rationally evenly arranged multiple spray head 8 at shower 6
Uniform fold, to outside pole shoe 10, can make uniformly to cool down on pole shoe 10.
These are only present pre-ferred embodiments, not in order to limit the present invention, all spirit in the present invention and former
Any amendment, equivalent and the improvement etc. made within then, should be included within the scope of the present invention.This specification
In the content that is not described in detail belong to prior art known to professional and technical personnel in the field.
