1.  The Invention

 

Title:

Roller Gearing and Transmission Mechanism

The problem the inventor(s) wanted to solve:

Improve the performance of mechanical gearing and transmission devices such as higher power efficiency, higher contact factor and no back-lash

Description:

Rollers are introduced between the driving and driven wheels that when transmitting torque roll along the grooves machined onto the surfaces of the two wheels. The special shape and curve of the grooves ensure that the rollers carry out pure rolling motion with theoretically zero sliding friction.

 

Presentation:  

There are two wheels (they can also be linear racks) with grooves on their surfaces and there are a number of rollers (e.g. balls) between the wheels rolling along the grooves. There is also a roller re-circulating mechanism that guides the rollers from the exit point on the grooves back to the entrance point.


Fields of application:

Applicable in all industries where mechanical gearing and power transmission is necessary including vehicles such as cars, trucks, trains, ships and aircrafts, but also cranes, lifts, conveyors and escalators, machines tools, pumps, mills, windfarms etc. 


Advantages:

Close to 100% power transmission efficiency, contact factor up to 20 or more, no back-lash. The implications of these include low operating costs, long lifetime, small size, high reliability, low noise and also smooth and precise movement. Also the design is very flexible and universally applicable for any geometry and applications. 


Stage of development:

Several prototypes ready and tested, just started pre-production phase
