Abstract
The function that there is exciter for solution prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is comparatively single, does not play the problems such as thermolysis, the utility model proposes a kind of Excitation Mode of Medium and Small Hydraulic Generator machine rotor support.The utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support, it is characterized in that, this support comprises rotating shaft cover, arc connects gusset and outer shroud, the quantity that described arc connects gusset is three or more, its front shape is trapezoidal and surface, edge is curved, further, and rotating shaft overlap and be axially arranged between rotating shaft cover and outer shroud in skewed.The Advantageous Effects of the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is when ensureing that excitation rotor normally runs, and plays the effect of fan, drives air flowing, improves radiating efficiency.
Description
Technical field
The utility model relates to Excitation Mode of Medium and Small Hydraulic Generator machine rotor support technology, is related specifically to a kind of Excitation Mode of Medium and Small Hydraulic Generator machine rotor support.
Background technology
Excitation Mode of Medium and Small Hydraulic Generator machine is provided with rotor field spider, is mainly used in carrying field core and coil.Prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support comprises rotating shaft cover, connects gusset and outer shroud, described connection gusset front shape is trapezoidal, quantity is three or more, connects gusset and overlap the identical mode of axis with length direction and rotating shaft and to be distributed between rotating shaft cover and outer shroud thus to form rotor field spider.Field core and mounting coil in the outside of rotor field spider outer shroud, thus form exciter rotor.When motor runs, exciter rotor rotates with electric machine main shaft, and namely rotor field spider carries field core and coil and rotates together with main shaft.But in motor operation course, iron core and coil all can produce larger heat, need good radiating condition.And prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is comparatively single in the function of exciter, do not play the effect of heat radiation.In addition, due to Medium and Small Hydraulic Generator compact conformation, exciter end incoming air area reduces, and radiating effect reduces, and needs to strengthen heat radiation dynamics.Obviously, the function that prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support also exists exciter is comparatively single, does not play the problems such as thermolysis.
Summary of the invention
The function that there is exciter for solution prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is comparatively single, does not play the problems such as thermolysis, the utility model proposes a kind of Excitation Mode of Medium and Small Hydraulic Generator machine rotor support.The utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support, it is characterized in that, this support comprises rotating shaft cover, arc connects gusset and outer shroud, the quantity that described arc connects gusset is three or more, its front shape is trapezoidal and surface, edge is curved, further, and rotating shaft overlap and be axially arranged between rotating shaft cover and outer shroud in skewed.
The Advantageous Effects of the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is when ensureing that excitation rotor normally runs, and plays the effect of fan, drives air flowing, improves radiating efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support front elevational schematic;
Accompanying drawing 2 is prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support schematic side view;

Below in conjunction with the drawings and specific embodiments, the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is further described.
Embodiment
Accompanying drawing 1 is prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support front elevational schematic, and accompanying drawing 2 is prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support schematic side view, and in figure, 1 is rotating shaft cover, and 2 for connecting gusset, and 3 is outer shroud.As seen from the figure, prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support comprises rotating shaft cover 1, connects gusset 2 and outer shroud 3, described connection gusset 2 front shape is trapezoidal, quantity is three or more, connects gusset 2 and overlap the identical mode of 1 axis with length direction and rotating shaft and be distributed on rotating shaft and overlap between 1 and outer shroud 3 thus to form rotor field spider.Field core and mounting coil in the outside of rotor field spider outer shroud, thus form exciter rotor.When motor runs, exciter rotor rotates with electric machine main shaft, and namely rotor field spider carries field core and coil and rotates together with main shaft.But in motor operation course, various iron core and coil all can produce larger heat, need good radiating condition.And prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is comparatively single in the function of exciter, do not play the effect of heat radiation.Obviously, the function that prior art Excitation Mode of Medium and Small Hydraulic Generator machine rotor support also exists exciter is comparatively single, does not play the problems such as thermolysis.
Accompanying drawing 3 is the schematic three dimensional views of the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support, and in figure, 1 is rotating shaft cover, and 3 is outer shroud, and 4 is arc connection gusset.As seen from the figure, the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support, it is characterized in that, this support comprises rotating shaft cover 1, arc connects gusset 4 and outer shroud 3, the quantity that described arc connects gusset 4 is three or more, its front shape is trapezoidal and curved along surface, and, and rotating shaft overlap 1 be axially skewedly be arranged on rotating shaft and overlap between 1 and outer shroud 3.Be not difficult to find out, the connection gusset of the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is identical with mounting means with the shape of fan blade, when exciter rotor rotates with electric machine main shaft, its rotor field spider is equivalent to an aerofoil fan, drive ambient air flows, take away heat, improve radiating efficiency.
Obviously, the Advantageous Effects of the utility model Excitation Mode of Medium and Small Hydraulic Generator machine rotor support is when ensureing that excitation rotor normally runs, and plays the effect of fan, drives air flowing, improves radiating efficiency.
