Summary of the invention
The purpose of the present invention is contemplated to overcome the fixing trouble of existing screw mandrel, and fixing device cannot Or be difficult to adjust, insecure defect fixed by screw mandrel, devises a kind of screw mandrel axial securing means for impeller, The position of pressing nut is adjustable, screw mandrel convenient fixing, gland convenient fixing, reliable, pressing spiral shell Female easy to adjust, laborsaving.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
A kind of screw mandrel axial securing means for impeller, including base, screw mandrel, soket head cap screw, the described end Seat is fixed on bed piece with described soket head cap screw, and the centre of described base is machined with bearing Bore, described screw mandrel uses radial ball bearing to be supported in bearing saddle bore, also includes gland, pressure Closing nut, described gland is fixed on the leading flank of described base with described soket head cap screw, described Pressing nut screws in described gland, and the end of described screw mandrel is fixed by described pressing nut.
Being machined with circular hole in the middle of described gland, its inner surface is tapped, and described pressing nut is i.e. Screw in the screwed hole of described gland.
The described soket head cap screw being used for fixing described gland has four, is uniformly arranged on described On the endoporus of gland and the circumference of cylindrical intermediate symmetry.
The middle trailing flank of described pressing nut is machined with annular heavy stand.
It is machined with equally distributed gap slot on the excircle of described pressing nut.
Owing to have employed above technical scheme, present invention have the advantage that
Base, screw mandrel, soket head cap screw, gland, pressing nut is used to combine designed Screw mandrel axial securing means for impeller, screw mandrel axial securing means for impeller disclosed in this invention, add in the middle of gland Work has circular hole, and its inner surface is tapped, and pressing nut i.e. screws in the screwed hole of gland, Being used for screw mandrel is carried out axial restraint, the position of pressing nut can adjust, therefore solid to screw mandrel Fixed convenient, the soket head cap screw being used for fixing gland has four, is uniformly arranged on the interior of gland On the circumference of hole and cylindrical intermediate symmetry, convenient fixing, reliable, on rear side of the centre of pressing nut Face is machined with annular heavy stand, and the end of screw mandrel i.e. relies on annular heavy stand to carry out axial restraint, pressing Equally distributed gap slot it is machined with on the excircle of nut, when adjusting the position of pressing nut, The instruments such as spanner can snap in wherein easily, easy to adjust, laborsaving.
