Description
Technical field
The utility model relates to adjust a centerbody, in particular to a kind of Petal type regulating gate centerbody.
Background technique
Petal type regulating gate is air duct, fan blade and centerbody for adjusting centrifugal blower air output size, main component.
Centerbody is fixed in air duct by support plate (bar).Centerbody and air duct it is circumferential uniformly open up reciprocal correspondence and with fan blade number
Equal circular hole, fan blade both ends shaft is located among the circular hole of centerbody and air duct, so that fan blade is only capable of rotating around blade shaft.
Existing centerbody is along center of circular hole point half.Due to centerbody and air duct be drilling after again by support plate (bar) will in
Heart body is fixed among air duct.In the production process since the factor of the ovality of welding deformation and air duct makes centerbody and wind
The corresponding a circular hole coaxial degree of cylinder is poor, in order to enable fan blade not hinder rotation, often increases the circular hole of centerbody, makes center
There are biggish gaps for the circular hole and fan blade spindle of body, and the shaking of fan blade or centerbody is caused not to work.
Utility model content
The utility model proposes a kind of Petal type regulating gate centerbody, solve centerbody in the prior art and air duct pair
A circular hole coaxial degree answered is poor, in order to enable fan blade not hinder rotation, often increases the circular hole of centerbody, makes centerbody
There are biggish gaps for circular hole and fan blade spindle, cause the shaking of fan blade or the inoperative defect of centerbody.
The technical solution of the utility model is achieved in that
A kind of Petal type regulating gate centerbody, including upper shell and lower shell, the outer diameter and inner diameter of upper shell and lower shell
All the same, the upper surface center of upper shell is provided with axial bolt hole, and the lower end surface of upper shell is open end, the circle of upper shell
Several radial installation through-holes are uniformly offered on all side walls, installation through-hole is communicated to the lower end surface of upper shell, lower shell
Both ends of the surface are open end, and fixed device is fixedly connected in lower shell, axial tapped through hole is provided on fixed device, screw thread is logical
Hole is correspondingly arranged with bolt hole, and tapped through hole is bolted with bolt hole, is provided between upper shell and lower shell
Adjusting gasket.
Further, the installation through-hole includes rectangle carry hole portion and semicircle hole portion.
Further, the fixed device fixed link or fixed plate.
Further, the lower surface of the upper shell upper end is provided with reinforcement boss.
The utility model has the beneficial effects that the utility model includes upper shell and lower shell, lower shell passes through branch when use
Fagging (bar) is fixed in air duct, and upper shell is connect by bolt with lower shell, can be on upper shell by rotating upper shell
Installation through-hole carry out circumferential position adjusting, by replace different-thickness adjusting gasket, can to installation through-hole carry out axis
Adjusting to position keeps the installation through-hole on upper shell corresponding with the hole on air duct, has good concentricity；In addition this reality
Simple with new structure, processing technology is simple, at low cost, and use is also simple, is very easy to promote, practical, scientific and technological achievement
Conversion is simple.
