Vít Archimedes chạy bằng dòng nước

The ancient but remarkable Archimedes screw, which operates in water lifting mode, is usually driven by an external energy source - muscle or engine. I designed a screw equipped with a special impeller located on the same shaft and integral with the screw. This design allows the water flow to rotate the Archimedes screw without expending additional energy to lift the water. Even in this form, the Archimedes screw is significantly more compact than another ancient mechanism—a water-lifting wheel.

 All parts, including the screw, are printed without supports. The screw shaft is an M4 stainless steel stud. The lower shaft support is an M5 bolt with a hexagonal hole. The recesses of these holes are typically conical, allowing the pointed end of the shaft to be precisely inserted into them. For the upper support, I used a 695z bearing, but any other bearing of suitable dimensions can be used. 5 M4 nuts and washers. 20 M6 nuts and M6 studs for the housing.
