Abstract
An improved axial-flow impeller with a hub comprises a blade and the hub, and is characterized in that the hub consists of a round base and a cylinder, wherein the cylinder is extended by the round base and expanded gradually, is shaped like a frustum and provided with a long shaft and a short shaft; the front edge of the blade is fixedly connected with the short shaft of the cylinder which is adjacent to the round base, shaped like the frustum, and provided with the long shaft and the short shaft; the rear edge of the impeller is fixedly connected with the long shaft at other end of the cylinder which is shaped like the frustum and provided with the long shaft and the short shaft; and a shaft in the round base is concentric with the center of the cylinder which is shaped like the frustum and provided with the long shaft and the short shaft. As the structure is adopted, the angle between the blade and the hub is large, and the twist angle is small, thus effectively solving the problems of air flow dropping at the tail part of the blade, high noise and power consumption, and low efficiency.
Description
Technical field
The utility model relates to a kind of axial-flow blower.
Background technique
Present prior art, a kind of axial-flow blower comprises wheel hub, blade, long one-body molded the making of wheel hub and leaf, described wheel hub is cylindrical.Existing problems are: wheel hub blade twist angle is big, and the air-flow of blade afterbody is easy to generate the border layering, and causes air-flow from leaf abscission, blade efficiency is reduced and the noise rising.
Summary of the invention
The purpose of this utility model is: a kind of axial-flow blower that improves wheel hub is provided, and it can overcome deficiency of the prior art effectively, has the advantage that noise is little, efficient is high.
The utility model is achieved in that a kind of axial-flow blower that improves wheel hub, comprise blade, wheel hub, it is characterized in that: described wheel hub is by round base, with extend by round base gradually launch, cylindrical shell taper type, major and minor axis constitutes, blade inlet edge is fixedlyed connected with the minor axis place of the cylindrical shell of the round base adjacent, taper type, major and minor axis, vane trailing edge is fixedlyed connected with major axis place taper type, the major and minor axis cylindrical shell the other end, and the round base upper shaft hole is coaxial with the center of cylindrical shell taper type, major and minor axis.
Described a kind of axial-flow blower that improves wheel hub is characterized in that: cylindrical shell taper type, major and minor axis is the oval cylindrical shell of class with major and minor axis.
Described a kind of axial-flow blower that improves wheel hub is characterized in that: stiffening rib in the class elliptical cylinder of described taper type, and stiffening rib is fixedlyed connected with round base, the oval cylindrical shell of class; Stiffening rib along short-axis direction be symmetrical arranged, stiffening rib is also in the setting of major semi axis bilateral symmetry.
Described a kind of axial-flow blower that improves wheel hub is characterized in that: cylindrical shell taper type, major and minor axis is the rhombus cylindrical shell with major and minor axis.The incline place rounding of the rhombus cylindrical shell of described major and minor axis.
A kind of axial-flow blower that improves wheel hub of the utility model, owing to adopt such structure, the angle of blade and wheel hub is big, distortion angle is little, has solved effectively that the blade tail wind comes off, bath pitch, power consumption height, inefficient problem.
