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