Abstract
The utility model provides a support used for flow-channel-type frequency converter housing and mainly aims to solve technical problems that strength is small, stability is poor and concentricity is difficult to guarantee by adopting a prior supporting method. Key points of the technical scheme are that an inner arc ring (1) and an outer arc ring (3) with different diameters and arranged concentrically are supported by more than two flat steel spokes (2), so that the hollow fan-shaped arc-ring support is formed; the inner arc ring (1) contacts with the outer profile surface of the frequency converter housing (4) in a fitting manner and the outer arc ring (3) contacts with the inner surface of a flow-channel outer cylinder (5) in a fitting manner. The flow-channel-type support is mainly used for supporting the flow-channel-type frequency converter housing.
Description
Technical field
The utility model relates to a kind of flow channel type frequency converter shell support.
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 ensure 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.When 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.
Utility model content
The purpose of this utility model is to provide that a kind of intensity is high, good stability, flow channel type frequency converter shell support simple in structure, and this support also can be as some other functional part interior barrel body support frames such as axial flow blowers.
The utility model 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 beneficial effects of the utility model are:
1,, while adopting support to install, can effectively ensure 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 ensures.
