Torque Density
Key Innovations
Unique combined torque generation and anti-rotation mechanism dramatically reduces friction and part count.
Independent control of desired lash, including setting internal pre-load is possible through a single dimension adjustment.
Force is spread among many contact points allowing the use of plastic lobes while maintaining high torque capacity.
Reduces inertia, friction and distributes the load more evenly between lobes, improving load capacity and torque linearity.
Benefits
Increases efficiency
Proven to greatly improve power transfer efficiency in the range of 90% to 97% per stage.
Reduces costs
Substantially reduced part count, size & complexity simplifies and reduces manufacturing costs, and total cost of ownership.
Form meets function
The design increases torque per unit mass and volume, while enabling a smooth and quiet operation. The large hollow bore allows for cable routing and mechanical integration.
Applicable Markets
Wherever there’s a need for high efficiency rotary power conversion with a large speed ratio, compact form factor, hollow bore, high torque density or low mass.
