Abstract
The utility model relates to a centrifugal impeller, which comprises a wheel disc and an impeller, wherein the impeller is arranged on the wheel disc and is provided with blades, a sub wheel disc, a left end tooth, an end tooth ring and a wheel center left ring are arranged on the wheel disc, wherein the end tooth ring is provided with a right end tooth. The centrifugal impeller of the utility model adopts the structure of the wheel disc and the end teeth, a cavity is formed between the wheel disc and the sub wheel disc, the sub wheel disc, the end tooth and the wheel center left ring are in thin-wall structures, and the sub wheel disc, the left end teeth, the right end teeth, the wheel center left ring and the wheel disc are in arc connection. The centrifugal impeller of the utility model has the advantages of light weight, uniform stress distribution, good intensity and good rigidity, and improves the power-weight ratio of an engine.
Description
Technical field
The utility model relates to a kind of gas compressor, is specifically related to a kind of centrifugal impeller of gas compressor.
Background technique
Centrifugal compressor has simple and compact for structure, and size is little, the reliability height, and characteristics such as operating range is wide, and boosting capability is strong, thereby in turboshaft engine, be used widely.Centrifugal impeller is the important composition parts of centrifugal compressor, is made up of wheel disc and impeller.The wheel disc sectional shape of this centrifugal impeller is made of inner flow passage, endoporus, import end wall line, outlet end wall line, imports and exports the wall line parallel, and and axis normal.The wheel disc volume of the centrifugal impeller of this sectional shape is big, and Heavy Weight has reduced the power to weight ratio of motor.
Summary of the invention
The purpose of this utility model is to provide a kind of intensity good, lightweight centrifugal impeller.Centrifugal impeller of the present utility model comprises wheel disc and is located at the impeller of band blade on the wheel disc, it is characterized in that: described wheel disc is provided with accessory whorl dish, left end tooth, has the end tooth ring and the core wheel left side ring of right gear, and the accessory whorl dish is connected with the wheel disc circular arc with right gear.
Centrifugal impeller of the present utility model adopts wheel disc and end tooth structure, constitutes a cavity between wheel disc and the accessory whorl dish, and accessory whorl dish, end tooth and core wheel left side ring are thin walled structures, and accessory whorl dish, left end tooth, right gear, core wheel left side ring are connected with the wheel disc circular arc.Centrifugal impeller of the present utility model is in light weight, and stress distribution is even, and strength and stiffness are good, has improved the power to weight ratio of motor.
