Abstract
A rotational driveshaft coupler that converts a rotating shaft motion into two orthogonal oscillations and at the opposite side of this coupler, a third oscillator converts the oscillations back to a rotational motion. At least one slip free seal can be constructed from the coupler to its housing to separate the space occupied by the output shaft from the space occupied by the input shaft. Each of the three oscillating motions can be guided by bearings, gears and tracks to reduce frictions and heat generation. Permanent magnet pairs are used to prevent bifurcation and force the output shaft to follow the rotation direction of the input shaft. Unlike in magnetic coupling, the torque transmission here is direct.

A coupling method for converting an input shaft rotation to orthogonal oscillations at a contacting and non-rotating mechanical coupler then to an output shaft rotation;
- said coupling method comprising:
- a) joining an input shaft with a non-rotating oscillator on an input end of said mechanical coupler;
- b) joining an output shaft with a symmetric oscillator on an output end of said mechanical coupler;
- and
- c) converting the rotational motion of said input shaft into orthogonal oscillations using a plurality of oscillators which includes said oscillators in a) and b) at said mechanical coupler
- wherein converting rotations to oscillations can allow for a bonded seal between said mechanical coupler and its housing.
