Abstract:
1. A device for a synchronized transfer of a torque from a driving shaft to a driven shaft, comprising: N driving eccentrics, rigidly attached to the driving shaft and N driven eccentrics rigidly attached to the driven shaft, wherein N≧3; the eccentrics each comprising a corresponding eccentric hole containing the driving and the driven shaft respectively; wherein a totality of said eccentrics of the driving shaft have an eccentricity offset of 2π/N between each other; wherein a totality of said eccentrics of the driven shaft have an eccentricity offset of 2π/N between each other; wherein said device is further comprised of bearings being coupled to each of the eccentrics; wherein said bearings eliminate a vertical component of the torque, where the vertical component is perpendicular to a plane formed by both the driving shaft and the driven shaft; wherein said device is further comprised of non-rigid cables, and said cables constantly operate in tension; wherein said cables serve as flexible connecting elements, wherein each of the said flexible connecting elements interconnects one of a single eccentric located at the driving shaft with a respective eccentric located at the driven shaft via the bearings; wherein said non-rigid cables and the bearings operate simultaneously, preserve a constant distance between the driving shaft and the driven shaft and perform an automatic synchronization of the driving shaft and the driven shaft; wherein at least one pair of the eccentrics of the driving shaft has a relative non-zero eccentricity offset of less than 50 degrees between each other to eliminate a vibrational resonance with the device itself; wherein said bearings surround an outermost periphery of the eccentrics.
