Air motor based on free-floating piston design

Huco Dynatork product story

Huco Dynatork's air motor is based on a free-floating piston design that is capable of precise position control.
Maximum torque is transmitted on start-up and this can be adjusted to fine limits by standard air-flow valves.
Unlike other makes that operate with a system of metal pistons and connecting rods, the Huco Dynatork motor is suitable for stop/start load speed applications under load.
Unlike its vane counterpart, the Huco Dynatork air motor is also easier to seal, and is therefore more cost-efficient as most of the energy stored up in the compressed air is converted into motion.
In fact, it consumes up to 80 per cent less air than a vane motor providing cost savings even at maximum torque.
The clean motor is available with non-lube air supply and in a corrosion resistant or acetyl housing.
Aluminium foil tray manufacturer, Coppice Alupack, has replaced all its electric drives on rewind systems that handle the surplus foil after the aluminium coil has been stamped.
Inclusion of Huco Dynatork air motors has simplified the design and made it more controllable and safer.
Their clean, non-lube running has also ensured hygienic production.
The Huco Dynatork motors run from 0-220rpm for 24h a day in a cycle that goes from stall to start in the order of 60 times per minute.
James Lamin, engineering manager at Coppice Alupack, said: 'The piston air motor has allowed us to adjust most of the tension out of the system to eliminate lacing breakage.
'It has also made the process inherently safer by reducing torque and negating the need for any electrical cables.' A further benefit is that maintenance of the motors can now be carried out by a shop-floor technician instead of a skilled electrician, saving cost and minimising downtime.
The suitability of the Huco Dynatork motor for stop/start applications under load has also been proven by Greydon, a manufacturer of printing equipment for form, fill and seal packaging machinery.
Its Bagaire taped bag loader ensures bags are presented quickly and in exactly the same position to the operator, time after time.
This accuracy makes the system ideal for the inclusion of inkjet coding.
The operating principle is simple but effective.
A leader tape is wound around two drive pulleys.
When powered up, the system advances the bags by winding up the tape and pulling them up from underneath the load table.
The Huco Dynatork air motor is responsible for this operation and again provides a clean solution that is also suitable for washdown.
