Description

Five-shaft impeller for supercharger

Technical Field

The utility model discloses be applied to machinery, specifically be a five-axis impeller for booster.

Background

The gasoline engine uses a turbocharger, which is popular. Nowadays, the supercharging of the gasoline engine is accepted by the industry, and the energy saving effect of the gasoline engine after the use of a turbocharger is remarkable. It is expressed in three aspects: one is the increased mechanical efficiency of the engine. Compared with a supercharged engine and a non-supercharged engine with the same displacement, the supercharged engine generates higher power, the mechanical efficiency and the fuel economy of the engine are obviously improved, and a chassis and blades are easy to deform or even break due to the fact that a supercharger rotates at a high speed in a common five-axis impeller, so that the normal work of the engine is influenced, and even the engine is damaged.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a five-axis impeller for booster to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a five-axis impeller for booster, includes the chassis, be equipped with a plurality of blades on the chassis, the blade surface is equipped with the dovetail, the dovetail is embedded to have forked tail ceramic blade, be equipped with the bearing in the middle of the chassis, the inside anti-reverse device that is equipped with of bearing, anti-reverse device includes the gear, be equipped with two stoppers on the gear tooth's socket, the stopper rotates to be connected on branch, fixed connection transmission shaft in the middle of the gear.

Preferably, the chassis is plated with a nickel plating protective layer.

Preferably, the blade is wrapped with a graphite fiber layer.

Preferably, the base plate and the blade material are liquid metal castings.

Compared with the prior art, the beneficial effects of the utility model are that: because the ceramic blades are embedded on the blades, the deformation of the blades caused by high temperature can be greatly reduced, and the anti-reverse device can prevent the supercharger from being damaged by the reverse rotation of the impeller.

FIG. 2 is a plan view of a five-axis impeller for a supercharger;

FIG. 3 is a view of a blade dovetail configuration.

Wherein; 1 chassis, 2 blades, 3 dovetail grooves, 4 dovetail ceramic blades, 5 bearings, 6 anti-reverse devices, 61 gears, 62 limiting blocks, 63 supporting rods, 7 transmission shafts, 8 nickel-plated protective layers and 9 graphite fiber layers.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a five-axis impeller for booster, includes chassis 1, be equipped with a plurality of blades 2 on the

chassis

1, 2 surfaces of blade are equipped with dovetail 3, dovetail 3 is embedded to have forked tail ceramic blade 4, be equipped with bearing 5 in the middle of the chassis 1, the inside anti-reverse device 6 that is equipped with of bearing 5, anti-reverse device 6 includes gear 61, be equipped with two stopper 62 on the gear 61 tooth's socket, stopper 62 rotates and connects on branch 63, fixed connection transmission shaft 7 in the middle of the gear 61.

Specifically, the chassis 1 is plated with a nickel plating protective layer 8.

Increasing the wear and corrosion resistance of the surface.

Specifically, the blade 2 is wrapped with a graphite fiber layer 9.

The graphite has good high temperature resistance, thermal conductivity and thermal shock resistance, and the addition of the graphite fiber layer can effectively improve the thermal shock resistance of the blade and avoid the thermal deformation or compression fracture of the blade.

Specifically, the base plate 1 and the blades 2 are made of liquid metal castings.

Liquid metal can produce the convection current under the difference in temperature effect, and the heat conductivity is greater than solid metal far away, makes whole temperature even, avoids local high temperature that produces, the control deformation volume of being heated.

Working principle; referring to fig. 1 to 3, a five-axis impeller for a supercharger comprises a chassis and blades, wherein ceramic dovetail blades are embedded in blade dovetail grooves, so that falling off during rotation can be effectively prevented, high temperature generated by rotation can be greatly reduced, and an anti-reverse device in a bearing can only rotate in a single direction through the five-axis impeller with a limiting block.
