Description
Technical field
The present invention relates to the manufacturing technology of machinery, and in particular to a kind of Wind-cooling type magnetic powder brake.
Background technology
Although conventional Wind-cooling type magnetic powder brake can improve the surface temperature of magnetic powder brake to a certain extent, to it
The improvement of magnetic working face temperature is less notable inside magnetic powder brake, still result in magnetic powder brake internal temperature compared with
Height, the parts that are, which receive high temperature, influences deformation or scaling loss, and bearing most easily burns, oil starvation, particularly working media --- magnetic by
High-temperature oxydation, scab failure, so as to shorten magnetic powder brake service life.
For the magnetic powder brake of natural cooling type, due to the magnetic system of its nominal torque and the relative water-cooling type of slip power
Dynamic device is smaller, and market has wide range of applications, value refer in itself it is smaller, do not apply to using water cooling structure type, and
For slip power often beyond permissible value, conventional method is to be directly blown onto magnetic powder brake surface using fan during actual use
Cooling, although the temperature of this cool-down method brake surfaces has declined, the production warm spot of magnetic powder brake is in its work
Make at surface, its internal temperature also when it is higher, the service life of magnetic receives the influence of high temperature and reduced.
The cooling means of magnetic powder brake substantially has following three kinds at present：1. the magnetic powder brake condition of larger slip power
Allow the lower cool-down method cooled down using cooling water circulation；2. effected by environmental factors only directly cool down magnetic using fan
The cool-down method of powder brake surfaces；3. other are not used to force the direct natural cooling of the type of cooling.Wherein, second and third kind
Market is using more, because magnetic powder brake under thermal capacity as defined at present no more than using, during using natural cooling, due to
Influenceed by factors such as environment temperature, natural situations, during magnetic powder brake real work, magnetic powder brake surface temperature often compared with
Height, performance is caused to decline.The method used at present is that fan blows drop method, due to only dropping magnetic powder brake surface temperature, temperature
Rise and make moderate progress, but cooling effect is still less obvious.
To solve above-mentioned drawback, spy of the present invention devises a kind of Wind-cooling type magnetic powder brake, by changing magnetic powder brake
The structure of stator interior so that cooling wind is directly blown onto at its working surface, so as to effectively reduce its operating temperature, reaches expected
Effect.
The content of the invention
It is an object of the invention to provide a kind of Wind-cooling type magnetic powder brake, solve one in above-mentioned prior art problem or
Person is multiple.
According to an aspect of the present invention, including rotating shaft and be sheathed on the rotating shaft brake rotors, braking stator, it is described
Stator sleeve is braked outside the brake rotors, the brake rotors and the braking stator can be around the axis of rotation, institutes
State and be provided with work magnetic between brake rotors and the braking stator；Also include the brake line for being located on the braking stator exterior
Box is enclosed, magnet exciting coil is provided with the restraining coil box；The braking stator shaft orientation offers some cooling air holes；Fan,
Air outlet communicates with the cooling air holes.
The design is by changing the structure of magnetic powder brake stator interior so that cooling wind is directly blown onto its working surface
Place, so as to effectively reduce its operating temperature, produce a desired effect.
In some embodiments, the brake rotors outer wall ring is provided with some grooves, adjacent two groove phases
Mutually separation.The fitting area of braking stator and brake rotors is further reduced, further improves air cooling effect.

Turn 200 and the braking stator 300 can rotate around the rotating shaft 100, the brake rotors 200 and the braking stator
Work magnetic is provided between 300；Also include being located on the restraining coil box 400 outside the braking stator 300, the brake line
Magnet exciting coil 500 is provided with circle box 400；The braking stator 300 axially offers some cooling air holes 310；Fan 600,
Air outlet communicates with the cooling air holes 310.
The design is by changing the structure of magnetic powder brake stator interior so that cooling wind is directly blown onto its working surface
Place, so as to effectively reduce its operating temperature, produce a desired effect.
According to Fig. 1, the outer wall ring of brake rotors 200 is provided with some grooves 700, adjacent two grooves
700 are separated from each other.The fitting area of braking stator 300 and brake rotors 200 is further reduced, further improves air cooling effect.
Presented above is only the preferred embodiment of the present invention, it is noted that to those skilled in the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these also should be regarded as the protection of the present invention
