Groundbreaking advantages

 

At IMSystems, we believe that the Archimedes Drive is the first major transmission revolution in over half a century, improving the world of mechatronic applications forever. Due to its many advantages, the Archimedes Drive can enable the creation of innovations that are currently only being dreamed of.

Innovation

Uncomplicated design

The Archimedes Drive: based on the same configuration as a planetary transmission. However, it uses friction instead of gear teeth to transmit torque. A planetary transmission uses the sun wheel in the center as the input. This sun wheel is surrounded by planet wheels, which are rolling over the teeth of a grounded output annulus. The difference in the speed of the planets moving around the drive compared to the input rotational velocity results in the desired gear ratio. Furthermore, you will experience increased torque.

Problem solved

The Archimedes Drive is a robust solution and is suitable for an infinite amount of applications. However, the gear ratio of a single stage is limited relying on multiple drives in series. Our technology solves this by combining two other principles: the compound principle and tractional contact.

Best of all worlds

Combining the planetary configuration with traction torque transmission and the compound principle results in the drive having two annuli and each planet having two diameters. One fixed annulus and the other being the output. The sun wheel is used as input, driving the planet wheels. These planets are hollow and are compressed between the sun wheel and the annuli, generating the required force for tractional torque transfer.

Sky high ratio’s

The difference in diameter within the planets is mainly responsible for the gear ratio. This difference makes it possible to produce drives with extremely high single-stage ratios of up to 10,000:1, more than 25 times higher than what is available today. Additionally, the continues contact within the drive eliminates play within the system, largely removing back-lash.

Gears throughout history

1200

The traditional wooden gearbox used in Dutch windmills made it possible to improve the lives of many. They allowed the grain to be milled and made it possible to pump water, increasing food production and irrigation.

1900

The herringbone gear was an instrumental innovation; it allowed the transferring of torque without producing an additional axial load. This sparked an industrial revolution which allowed complex manufacturing processes to be simplified.

With almost no backlash, lightweight and high single stage gear ratios, the strain wave gear pushed the boundaries of transmissions even further. While it made it possible to communicate with people on the moon, it also formed the foundation of robotics.

Like its predecessors, the Archimedes Drive helps initiate the fourth industrial revolution, drastically altering the world we live in today. With its numerous advantages, it improves current technologies and enables new areas of innovation.
