Description
Technical field
The present invention relates to a kind of flow channel type frequency converter shell support and processing method thereof.
Background technology
At present, the inside cylindrical shell of some other functional part of axial flow blower, while being fixed in outside cylindrical shell, traditional supporting way, is to adopt many radially spokes, the inner surface of one end welding outer cylinder body, one end is welded on the outer surface of inner core.This fixed form, due to the error of processing and manufacturing aspect, is usually difficult to guarantee that inside and outside cylindrical shell is concentric.Flow channel type frequency converter shell is opened in subdivision position because of needs, and electric elements inside is safeguarded and overhauled, and should not adopt support bar that housing and outer cylinder body are welded.Therefore, designed a kind of support, this support is to be formed by three flat steel bar soldering group, and wherein two as supporting leg, and with contacting of outer tube inner surface, another root is that bearing-surface contacts with frequency converter shell.As the flat steel bar of supporting leg, with the cross section that outer tube inner surface contact portion is generous direction place, contact area is little, no matter be that intensity or stability are all very poor.The flat steel bar contacting with shell of frequency converter is support housing in the horizontal direction, and surface of shell is arc surface, can not directly contact, thereby, housing is sliced off at the arc surface of installation site, with the flat steel bar of support flat steel bar opposite position weldering of support.Like this, the structural strength of housing has larger impact.Even like this, the band steel supporting surface on support, still has the phenomenon misfitting.During machining support, need to adopt frock guarantee guarantee contour dimension basic identical.When mounted, because of many reasons,, often there is off-set phenomenon at the center of frequency converter shell and outer cylinder body.Thereby, must adopt the mode of joining weldering to be fixed.Interchangeability is also poor.
Summary of the invention
The object of this invention is to provide that a kind of intensity is high, good stability, flow channel type frequency converter shell support and processing method thereof simple in structure, this support also can be as some other functional part interior barrel body support frames such as axial flow blowers.
First the present invention provides a kind of flow channel type frequency converter shell support, solving the technical scheme that its technical problem adopts is: different-diameter with one heart in arc ring 1 and outer arc ring 3, under supporting, band steel spoke 2 more than 2 surrounds hollow fan-shaped arc annular support, interior arc ring 1 matches and contacts with the gabarit surface of frequency converter shell 4, and outer arc ring 3 matches and contacts with the inner surface of the outside cylindrical shell 5 of runner.
Interior arc ring 1 and outer arc ring 3 adopt band steel.
The central angle of interior arc ring 1 and outer arc ring 3 correspondences is 90 °, and in same direction.
On interior arc ring 1, there is 1 above through hole, position is identical with the through hole of the gabarit arc surface of frequency converter shell 4 with quantity, and the inner surface diameter of interior arc ring 1 is identical with frequency converter shell gabarit surface diameter, the exterior arc surface diameter of outer arc ring 3 is identical with the inner surface diameter of the outside cylindrical shell 5 of runner.
The radial distance of the inner surface of the outer surface of interior arc ring 1 and outer arc ring 3 equals radius poor on outside cylindrical shell 5 inner surfaces of runner and frequency converter shell 4 gabarit surfaces.
A frequency converter shell 4 of 1 common supporting of above support.
It also can be as the support of other inner circular cylindrical shell.
The present invention also provides a kind of flow channel type frequency converter shell support processing method, solving the technical scheme that its technical problem adopts is: two band steel annulus that diameter is different, under more than 8, band steel spoke 2 supports, form an open circles ring body, along the circumferential direction ring is divided into four fan-shaped arc rings, at position of halving, there are 2 adjacent band steel support bars 2, and there is certain gap apart, after band steel spoke 2 is connected by welding with interior annulus and outer toroid, internally the inner surface of annulus and the outer surface of outer toroid carry out school circle or processing respectively; Then, at the place, gap of two adjacent band steel spokes 2, cut off, be divided into four identical hollow fan-shaped arc rings.
The inner surface diameter of interior annulus is identical with frequency converter shell gabarit 4 surface diameters, and the exterior arc surface diameter of outer toroid is identical with the inner surface diameter of the outside cylindrical shell 5 of runner.
On the interior arc ring 1 of fan-shaped arc ring, process through hole.
The invention has the beneficial effects as follows:
While 1, adopting support to install, can effectively guarantee the concentricity of the inner cylindrical shell of other functional part of frequency converter shell and blower fan and outside cylindrical shell, and, substantially do not need to adjust.
2, interior outer bearing surface is all arc surface, and contact area is large, and bearing strength is large, the good stability of supporting.Support itself is closed structure.Its intensity is also much bigger than the open structure of three band steel welding.
3, after entirety processing, then, be divided into four identical independent racks.Cut lengths precision has consistency, and interchangeability is good.
4, adopt entirety processing, cut apart use, manufacture craft is simple, processes littlely, and dimensional accuracy also easily guarantees.
