Abstract

The invention relates to a gas compressor impeller, which comprises a wheel disc, wherein the wheel disc is a circular disc, a shaft hole is formed in the center of the wheel disc, the center of one side of the wheel disc is provided with a shaft sleeve, the inner diameter of the shaft sleeve is identical to and corresponds to the diameter of the shaft hole formed in the wheel disc, the appearance of the shaft sleeve is in a horn shape, one end of a horn mouth of the shaft sleeve forms a whole with the wheel disc, and blades are uniformly distributed around the shaft sleeve. The gas compressor impeller is characterized in that the blades arranged on the end, far away from the wheel disc, of the shaft sleeve are arranged in a one-long-blade and one-short-blade alternate way, so that in the adjacent blades, one impeller is the long impeller, and the other impeller is the short impeller. When the gas compressor impeller is adopted, the fuel oil consumption can be reduced, and the occurrence of an overheat phenomenon of an engine is voided. The gas compressor impeller is applicable to an automobile engine supercharger.

Description

technical field

[0001] The invention relates to an impeller. Specifically, the compressor wheel on the turbocharger. Suitable for car engine. Background technique

[0002] It is known in the field of automobile manufacturing that installing a supercharger on the exhaust pipe of an automobile engine can improve automobile power, reduce fuel consumption, reduce automobile exhaust emissions and air pollution. Therefore, it is adopted by many car manufacturers. At present, the compressor impellers used in automobile superchargers are all traditional impellers. This traditional impeller contains a disc. The disc is a disc with a shaft hole processed in its center and a shaft sleeve in the center of one side. The inner diameter of the sleeve is equal to and corresponds to the shaft hole on the wheel disc. The shape of the shaft sleeve is trumpet-shaped, so that the diameter of one end thereof is larger than that of the other end. The big end of the shaft sleeve is integrated ...
