Abstract
The invention provides a positioning part for an axial flow impeller. The positioning part is characterized in that a positioning part main body comprises a cock body arranged in a hub clamp slot and a cock body arranged in a vane clamp slot; the two cock bodies intersect in the same plane; the radial cross sections of the cock body in the hub clamp slot are centrosymmetric graphs; the symmetric center lines of the radial cross sections are parallel to the vertical line of the plane; and the point of intersection of the intersecting lines of all the radial cross sections of the cock body (1-1) and the plane in the center of the plane does not coincide with the point of intersection of the intersecting lines of all the radial cross sections of the cock body (1-2) and the plane in the center of the plane. The position of a vane relative to the disc is adjusted by adjusting the shape of the positioning part, namely changing the relative offset positions of the two cock bodies of the positioning part, thus realizing the adjustment of a plurality of angles on the basis of the existing angle.

Technical field
The present invention relates to a kind of ventilation equipment accessory field, particularly a kind of axial-flow blower locating piece.
Background technique
The impeller blade mounting structure kind of axial-flow blower is a lot, the normal at present rivet arrangement that adopts, welded structure or integral die-cast structure, but adopt this mode to install, there is the shortcoming that the blade installation location is inaccurate and impeller performance can not be regulated, can not utilize the problem that angle is regulated the size of impeller air quantity and blast of adjusting, in order to address this problem often to adopt at present a plurality of locating slots are set in the groove of wheel hub, thereby and blade pass is crossed locating piece be stuck in different locating slots and realize adjustment blade angle, but because employed locating piece adopts cylindrical locating piece 1 ' as shown in Figure 1 mostly, therefore the angle that can regulate is limited, DeGrain.
Summary of the invention
At above problem, the present invention is by improving with the locating piece structure existing a kind of axial-flow blower, thereby under the situation of not improving the axial-flow blower wheel hub structure, by exchanging the axial-flow blower locating piece, can adjust blade angle, for reaching this purpose, the invention provides the locating piece that a kind of axial-flow blower blade is used, described locating piece main body is made up of with the cock body that is positioned at the blade draw-in groove the cock body that lays respectively in the wheel hub draw-in groove, described cock body and cock body intersect at same plane, the radial cross-section of the cock body in the described wheel hub groove is a centrosymmetric image, the symmetrical center line of described radial cross-section is parallel with the vertical line on plane, and all radial cross-sections of cock body do not overlap with the set of intersection at the center on plane on plane in the set at the center on plane and all radial cross-sections of cock body with the intersection on plane.
As a further improvement on the present invention, the radial cross-section of described cock body is semicircle or triangle or trapezoidal or profile of tooth, the radial cross-section of this patent cock body can be different cross section, and producer can carry out the locating piece of production outer surfaces according to wheel hub and blade locating slot inner surface structure.
As a further improvement on the present invention, the radial cross-sectional shape of described 2 cock bodys is inequality, the cross-sectional sizes difference of the radial cross-section of 2 cock bodys, the radial cross-section of 2 cock bodys of this patent can be the same or different, cross-sectional sizes can be identical also can be inequality, producer can select corresponding radial cross section to produce according to actual conditions.
The present invention is the shape by the adjustment locating piece, promptly changes the relativity shift position of two cock bodys of locating piece, adjusts the position of blade with respect to dish to reach, thereby obtains numerous angular adjustment on the basis of existing angle.
