The purpose of this utility model is to provide a kind of stator support frame, can replace the stator disc using in prior art, and greatly reduces the manufacturing cost of retarder.
In order to realize above-mentioned utility model object, the utility model provides a kind of stator support frame for current vortex retarder, for fixed magnetic pole, it is characterized in that, this stator support frame is formed by metal casting.
The utility model provides this to comprise the circular configuration of a hollow for the stator support frame of current vortex retarder, and the outside of this circular configuration equidistantly distributes at least three outrigger shafts, and the length of this outrigger shaft is consistent, and this magnetic pole is positioned between two outrigger shafts.
Further, between these two outrigger shafts, place two magnetic poles.The outermost end of this each outrigger shaft also comprises vertical with this outrigger shaft and is positioned at conplane block, in order to prevent that this magnetic pole is subjected to displacement.This circular configuration comprises some projections that equidistantly distribute, and this protruding direction is vertical with the direction of this outrigger shaft, and the plane at this projection place is vertical with the plane at this outrigger shaft place.The outermost end of this each outrigger shaft also comprises vertical with this outrigger shaft and is positioned at conplane block, this circular configuration comprises some projections that equidistantly distribute, this protruding direction is vertical with the direction of this outrigger shaft, and the plane at this projection place is vertical with the plane at this outrigger shaft place, the two ends of this block respectively comprise a projection, and the direction of this block projection is consistent with the protruding direction of this circular configuration.The protruding quantity of this circular configuration is consistent with the quantity of this magnetic pole.The side of the protruding close magnetic pole of this circular configuration is a semi-circular shape.This stator support frame is made up of aluminum or aluminum alloy.
Compared with prior art, stator support frame provided by the utility model does not need to be stamped to form, and manufacturing process becomes casting from punching press, greatly reduces manufacturing cost.And this stator support frame can be made up of aluminium alloy, can further reduce costs, and can also reduce the weight of retarder.
Brief description of the drawings
Can describe in detail and appended graphic being further understood by following utility model about advantage of the present utility model and spirit.
Fig. 1 is the retarder that uses in prior art and the structural representation of stator disc;
Fig. 2 is the structural representation of the related stator support frame of the utility model.
Embodiment
Describe the stator support frame of a kind of specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.But, the utility model should be understood as and be not limited to this execution mode described below, and technical concept of the present utility model can be implemented with other known technologies or the combination of function other technologies identical with those known technologies.In the following description, for clear structure of the present utility model and the working method of showing, to be described by all multidirectional words, but should be by Word Understandings such as 'fornt', 'back', " left side ", " right side ", " outward ", " interior ", " outwards ", " inwardly ", " axially ", " radially " for convenience of term, and not should be understood to word of limitation.Wherein, " interior " is construed as the position near stator support Jia center, and " outward " is construed as the position away from the center of stator line bracing frame.
The structure of stator disc of the prior art is similar to plate-like, and magnetic pole is arranged on stator disc by certain position relation.The stator disc using in prior art is generally steel, and by large-scale stamping machine punching press and, because the hole needing on stator disc is very many, cause manufacturing process complexity, and cost is very high.
The utility model provides a kind of stator support frame to replace the stator disc using in prior art.As shown in Figure 2, Fig. 2 is the structural representation of stator support frame provided by the utility model.The structure of this stator support frame is a symmetrical structure, comprises the circular configuration 10 of a hollow.Equidistant or the equal angles in the outside of this circular configuration 10 some axles 20 that distribute.In Fig. 2, given schematic diagram is that four axles 20 distribute, and the angle between every two axles 20 is 90 degree.But those skilled in the art will be appreciated that, present embodiment has just been given a kind of signal of preferred embodiment, be applicable to the common retarder stator with eight magnetic poles, if but the magnetic pole of this retarder stator is six, ten or other even numbers, can reduce accordingly or increase the quantity of axle 20.
This axle 20 is positioned at same plane with circular configuration 10.The length of each axle 20 is all consistent, and magnetic pole (in figure depending on not going out) is just placed between two axles 20.In the present embodiment, between two axles 20, place two magnetic poles.Be subjected to displacement in order to place magnetic pole, the end of each axle 20 is provided with baffle plate.The bearing of trend of baffle plate is vertical with axle 20, and is positioned at same plane with axle 20, circular configuration 10.Be subjected to displacement in order to place better magnetic pole, on baffle plate and circular configuration 10, be provided with some projections.The direction that wherein this projection is extended and axle 20, baffle plate are vertical with the plane at circular configuration 10 places.The quantity of projection 11 and the quantity of magnetic pole on circular configuration 10 are consistent, and equidistantly distribute.Wherein the projection 11 of half is positioned at the part that is connected of circular configuration 10 and axle 20, and second half projection is between diaxon 20.Projection 21 distributions on baffle plate and the two ends of baffle plate.The projection 11 of circular configuration 10 is designed to semicircle in the side near magnetic pole, and the benefit of doing is like this in order to be close to magnetic pole better, places magnetic pole and is subjected to displacement.
