Abstract
The utility model discloses a connecting structure for a paddle of a submersible water impeller and a hub. The connecting structure comprises the paddle (1) and the hub (2), and is characterized in that the tail end of the paddle (1) is provided with a flanged fixedly connected with the paddle; the flange (3) is embedded in a groove (4) on the hub (2); and the flange (3) is fixedly connected with the bottom of the groove (4) through screws (5). The tail end of the paddle and the side face of the hub are respectively provided with the flange and the groove which are matched with each other, and the flange and the groove are fixed by the screws; the connecting mode is simple and quick; the cast structure and machining of the hub are simple; meanwhile, by rotating the paddle, through holes on the flange are aligned with different screw holes at the bottom of the groove, and the mounting angle of the paddle can be adjusted; and the connecting structure has the characteristics of simple structure and low cost and is suitable for promotion and use.
Description
Technical field
The utility model relates to mechanical equipment technical field, specifically a kind of connection structure of dive under water impeller blade and wheel hub.
Background technology
The general employing of the blade of at present domestic diving impeller is shaft-mounted, and promptly propeller shank stretches out a brachymemma axle, after minor axis stretches into wheel hub, with briquetting axle is blocked, and briquetting is screwed on wheel hub again.This kind mounting structure is regulated the blade angles with different briquettings, and working accuracy, the intensity of briquetting is all had high requirement, and the cast structure of wheel hub is also comparatively complicated simultaneously.
Summary of the invention
The purpose of the utility model is the defective to prior art, and a kind of diving impeller blade simple in structure, easy for installation and the connection structure of wheel hub are provided.
The purpose of the utility model solves through following technical scheme:
A kind of connection structure of dive under water impeller blade and wheel hub comprises blade and wheel hub, and the tail end of said blade is provided with the flange that is fixedly linked with it, and described flange is embedded in the groove that is provided with on the wheel hub, and flange is fixedly linked through the bottom land of screw and groove.
Described groove is along the side rectangular distribution of wheel hub.
Described screw is along the end face rectangular distribution of flange.
Described flange is welded on the tail end of blade.
The utility model is compared prior art has following advantage:
This practicality is newly through being provided with flange and the groove that cooperatively interacts at the tail end of blade and the side of wheel hub respectively, and adopts screw retention flange and groove, this kind connection mode simple and fast, and the cast structure of wheel hub and process all simple relatively; Making the different screws on the through-hole alignment groove bottom land on the flange through revolving vane simultaneously is the setting angle of scalable blade.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Wherein: 1-blade; 2-wheel hub; 3-flange; 4-groove; 5-screw.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: a kind of connection structure of dive under water impeller blade and wheel hub; Comprise blade 1 and wheel hub 2; Be welded with the flange 3 that the afterbody axle head with blade 1 is fixedly linked at the tail end of blade 1, this flange 3 is embedded in the groove 4 that is provided with on the wheel hub 2, and groove 4 is along the side rectangular distribution of wheel hub 2; Flange 3 is provided with the well-distributed through hole; And the bottom land of groove 4 is provided with and the corresponding screw of above-mentioned through hole; So flange 3 is fixedly linked through the bottom land of screw 5 with groove 4; Be that the screw that the front end of screw 5 passes behind the through hole on the flange 3 with groove 4 bottom land settings is fixedly linked, screw 5 is along the end face rectangular distribution of flange 3.
This practicality is newly through being provided with the flange 3 and groove 4 that cooperatively interacts at the tail end of blade 1 and the side of wheel hub 2 respectively, and adopts screw 5 attachment flanges 3 and grooves 4; This kind connection mode simple and fast, and the cast structure of wheel hub and processing all simple relatively; Making the different screws on the through-hole alignment groove bottom land on the flange through revolving vane simultaneously is the setting angle of scalable blade.
The technology that the utility model does not relate to all can realize through prior art.
