Build your archimedean screws step by step

I don't know which screw I need

Step 1

Prepare your axes

Once you've received your modules, prepare the pins you need for your Archimedys™ screw assembly. Attach a pin to the end of the axle. Always provide a thread at the end of the axle to allow module locking.

The diameter of the support must always be at least equal to the diameter of the module core.

Step 2

Assemble your modules

Simply stack the modules on the axis, according to the screw profile you have defined. Start and end modules must have a flat contact face. TRH and FRH have a flat contact face as standard. It is possible to re-machine one side, or adjust the screw length.

Step 3

Lock your screw

Video explanation

Its modular polymer screw resists corrosion and abrasion, and can be assembled in just a few minutes.

Different end configurations are possible

Without machining the axis and using a standard hexagon socket.

Locking on the axle is achieved with a pin that is simply drilled when all modules are in position. This side can be used for mounting bearings.

The hexagonal pin is turned to the appropriate diameter. Next, a simple bushing is used to lock the modules in position with a pin.

The ends of the axle can be threaded to facilitate module locking. This side can be used for mounting bearings.

When the material flows in the direction of the screw, the modules can be locked in position with a conventional screw and steel washer.

The washer must have the same diameter as the module core.

Different motor configurations are also possible

Configuration 1 :

the hexagonal steel shaft is not machined. You can use a standard hexagon socket with a cylindrical zone to adapt the motor connection. The bushes are secured with two pins. The keyway can be made directly on the bushes.

Configuration 2 :

The hexagonal steel shaft is not machined. If hollow couplings are used, an additional pin can be fitted to the bushes.

Configuration 3 :

In this configuration, you need to machine the shaft and add bushes. Fixing is done with two pins on the shaft side.

Configuration 4 :

You can machine the end of the axle and add a steel bushing to lock the modules in position. The keyway is made on the axle.

Configuration 5 :

The hexagonal shaft is machined to match the shape of the end shaft. This configuration is mainly used when a drive extension is required.
