Abstract

For hundreds of years gears, levers, cams, and other assorted mechanical devices have been used to establish and maintain relative motion between objects. Presented here is a mechanism, which relies on magnetic fluid to establish an interface and maintain relative motion between objects. This disclosure is not in regard to the magnetic fluid developed by Lord Corporation, but rather the application for this or similar fluids.

INVENTION DISCLOSURE

Subject: Use of magnetic fluids to accomplish infinitely variable speed and power from a constant velocity/power source "The Simplicity Drive"

Sketch and Description:

    For hundreds of years gears, levers, cams, and other assorted mechanical devices have been used to establish and maintain relative motion between objects. Presented here is a mechanism, which relies on magnetic fluid to establish an interface and maintain relative motion between objects. This disclosure is not in regard to the magnetic fluid developed by Lord Corporation, but rather the application for this or similar fluids.

    Below is depicted a mechanism consisting of a male and female shaft, an enclosure, two seals, a magnetic field source, and an ample amount of magnetic fluid. The male and female shafts do not make physical contact with each other. Between them lies a media composed of magnetic fluid. In the absence of a magnetic field, the fluid flows according to the viscosity of the carrier or base, i.e. oil, silicone, water... When exposed to a magnetic field the fluid viscosity is altered according to the interaction between the field strength and fluid particulate. The important thing to recognize is, when exposed to a strong magnetic field, this fluid can with stand a 30-pound shear force (it behaves as a solid). Therefore, by varying the magnetic field located in the center of the input shaft (male), the velocity of the output shaft (female) can be varied. This is accomplished by fluid viscosity control, which directly corresponds...
