Description
Technical field
The utility model relates to a kind of hydraulic turbine model connectors, more specifically to a kind of 3D printing reversible water wheels
The assembling structure of machine model runner.
Background technique
The structure of existing reversible turbine model runner has following several:
It 1, include: blade, crown and lower ring using the model runner structure of machining.In processing model runner, lead to
Over mechanical processing means include: that the modes such as numerical control milling, turning process each section respectively, finally tight with pin positioning, screw
Solid mode blade, crown and lower ring are assembled into integral runner, pass through manual grinding knuckle after assembly and fill gap,
Wherein, blade is that band divides valve crown structure, and crown, lower ring are solid rotary structure.
2, using the model runner structure of 3D printing: a kind of " application number: 201620116919.1 3D printing reversible water wheels
It include the knot of model turbine runner and metal shaft coupling flange and the assembly of metal draft cone in machine model runner connection component "
Structure, by the way that threaded hole is arranged on runner baseplane, tapped through hole is arranged in corresponding position on metal shaft coupling flange, tight by screw
Connected acting flange and runner form entirety, and shaft coupling flange base and metal draft cone have interference fit.
The traditional processing mode of reversible turbine model runner are as follows: casting copper product blank is passed through into numerical control milling, vehicle

Integral runner is assembled, as shown in Figure 1.Wherein, blade is that band divides valve crown structure, and crown, lower ring are solid revolving body knot
Structure.
The appearance of 3D printing technique, make it possible quickly, high-precision entirety print model runner, wherein again divide
For metal material runner and nonmetallic materials runner.The production cost and period of metal material runner will be higher than non-metallic material
Material, surface roughness is then relatively poor, simultaneously because the size of model runner limits (maximum gauge 340mm or more), big portion
The molding range of parting category 3D printing equipment is also unable to reach, therefore 3D printing hydraulic turbine model runner more more options non-metallic material
Material.
By 3D printing nonmetallic materials runner, whole runner will be directly manufactured without original assembling structure.But
When model runner is applied to hydraulic test, then following problems are generated: (1) the driving motor main shaft and mould in hydraulic test device
Type runner matches, and is connected by key and realizes that torque is transmitted to drive runner to run at high speed, while bearing during the test
Water flow high pressure, therefore remove except the intensity of runner itself, it is still necessary to runner and the higher bonding strength guarantee of testing stand main shaft,
The keyway feature that non-metallic material is directly generated by 3D printing, since anti-twisting property is poor compared to metal material, by nothing
The transmitting of torque is completely secured in method, it is possible to key damage occurs and lead to the runner even entirely destruction of experimental rig；(2) 3D
The dimensional accuracy of printing is poor compared to being machined, and directly generates the hole characteristic matched with testing stand main shaft by 3D printing,
It will be unable to meet high-precision hole axle cooperation requirement, it is therefore desirable to secondary operation, but the cutting ability of plastic material is still not clear；
(3) cost of 3D printing is directly proportional to material, the higher cost of existing 3D printing.
