Precision or Accuracy? How the Archimedes Drive offers both
Discover how the Archimedes Drive ensures high accuracy with stiffness and precise movements with true zero backlash for optimal robot performance.
TECHNOLOGY
The Archimedes Drive is a patented traction-based speed reducer that revolutionizes the industry.
Offering true zero backlash, combined with high stiffness and efficiency.
It combines the compound planetary principle for efficient distribution, and transmission of rotational forces using traction rollers.
This innovative design offers unprecedented precision, and zero backlash, while maintaining efficiency and offering a unique overtorque protection.

True Zero Backlash
The key components are specially designed smooth hollow rollers. As the rollers moves, it transmits rotational motion from the input to the output, with continuous contact. This method eliminates the need for teeth and thus avoids the common issues of backlash and wear found in toothed gears.
Overtorque Protection
When subjected to excessive torque due to vibrations, shocks, or pressure exceeding nominal torque, these drives seamlessly transition into a sliding regime. This intelligent response prevents damage to the system by effectively managing unexpected overload conditions.
Low Noise Level
Whether in industrial settings or consumer applications, their low noise emission ensures smooth and unobtrusive presence. Furthermore the Archimedes Drive emits a low-frequency noise which is ideal for human-robot interaction. This characteristic makes it particularly suitable for environments where noise pollution needs to be minimized.
Easy Backdrivable
The Archimedes Drives exhibit exceptional backdrivability, facilitating smooth manual manipulation of the system as needed. This transparency in the mechanism aids in robots control system's performance, allowing for better overall operation and control. .
Unparalleled Efficiency
By utilizing a friction-based mechanism, minimal energy is lost due to the elimination of vibrations and heat within Archimedes Drives. This design prioritizes energy efficiency by minimizing losses, thereby maximizing the conversion of input power into useful output motion. The result is: reduced energy consumption and enhanced overall performance.
Fundamental principles:
The Archimedes Drive represents a breakthrough in traction-based drive technology, designed to surpass existing systems in efficiency and performance. This innovative drive combines two foundational principles:
Compound Planetary Principle - also known as Wolfrom drive, involves a layout where multiple planetary elements operate in a compact setup to achieve high reduction ratio's.
Traction - involves smooth cylinders that rely on frictional contact to transfer torque. Continuous contact leads to zero backlash, high stiffness, and high efficiency.
Compound Planetary Traction Drive
These two principles form the core of the Archimedes Drive, named the ‘Compound Planetary Traction Drive’. This design allows for compact and robust construction, capable of transmitting high torque loads while being less susceptible to mechanical wear and efficiency losses due to its minimalistic internal architecture.
