The Rotrex Supercharger:
Traction drives transmit power through friction forces between its rolling elements. Great speeds and low noise are just some of the advantages of traction drives over traditional gear transmissions.
The Rotrex Supercharger uses a patented traction drive system. The drive system is comprised of an annulus, three rollers, and a center shaft to the compressor. The patented "ramp effect" in the traction drive increases efficiency and reliability in the drive by regulating the torque transfer capability on demand through self-adjusting planetary rollers.
The Rotrex uses a unique traction fluid called Rotrex SX100. SX100 works by increasing viscosity under high surface pressure, enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system. The Rotrex supercharger pumps the SX100 fluid and does not tie into the engine oil at all, so there is no need to add an oil pump or tap your oil pan.
