Abstract
The utility model discloses a fastening mechanism for the impeller of a waterwheel-type automatic aerator and mainly comprises a vane, an impeller seat, a drive shaft and a metal sleeve, or the like. The technical project of the utility model is that the outer rim of a plastic impeller axle hole is provided with a pocket to locate a cap nut and a hole for a holding screw to get through. The outer rim of the axle hole is provided with the metal sleeve, and the holding screw gets through the metal sleeve and the cap nut to fix the impeller to the drive shaft. The pocket for the cap nut and the hole for the holding screw are made into gaps. The diameter of the holding screw on the outer rim of the axle hole is slightly smaller than the external thread diameter of the holding screw. The holding screw acts a force on the shaft and is supported by the metal sleeve, which saves the trouble of producing a hexagonal axle hole and a copper insert to reduce costs.
Description
Technical field
The utility model relates to the impeller of oxygenating machine, particularly relates to the retention mechanism of waterwheel aerator impeller.
Background technology
Oxygenating machine is the equipment that in the aquaculture fishes and shrimps is had lifesaving and growth encourage.The prior mechanical oxygenating machine mainly contains water wheel type, vane type and water jet three major types type, and wherein waterwheel aerator uses wider.Waterwheel aerator impeller commonly used is to be made of plastics, and endoporus is made sexangle, square, also corresponding sexangle and square will be arranged on the axle, also has at the impeller endoporus to be shaped on copper insert.Screw is arranged on the copper insert, be fixed on the transmission shaft, complex process, cost height with holding screw.
Summary of the invention
The purpose of this utility model is the retention mechanism of a kind of waterwheel aerator impeller of design, solves the deficiency of the retention mechanism of existing waterwheel aerator impeller.A kind of retention mechanism of novel waterwheel aerator impeller impeller is provided, the technical solution of the utility model is, the impeller axis hole outer rim that plastics are made is shaped on the depression of placing nut, with hole by holding screw, the axis hole outer rim has metallic sheath, holding screw is fastened on impeller on the transmission shaft by metallic sheath and nut.
Metallic sheath described in the utility model is to have stainless plate stretching to make, and flange is arranged outward, and the anti-limit of endoporus becomes cylindrical hole.
The nut depression and the screw hole of the axis hole outer rim of waterwheel aerator impeller described in the utility model, screw hole can be made into breach.
The screw aperture of the axis hole outer rim of waterwheel aerator impeller described in the utility model is slightly less than the thread root diameter of holding screw, and holding screw passes through, and anti-loosening effect is arranged.
The utility model holding screw by the metallic sheath supporting, has saved the trouble of making sexangle axis hole and copper insert to the axle reactive force, reduces cost.
