Title: MAGNETIC COUPLING DEVICE
Abstract:
The present disclosure provides a system for transmitting rotational motion between a driving element and a driven element. The system comprises a driving element that is coupled to a torque input that causes the driving element to rotate about a drive axis. The driving element comprises a first magnetic element. A driven element is configured to rotate about a driven axis. The driven element comprises a second magnetic element. Both the first magnetic element and second magnetic element are susceptible to a magnetic field, and at least one of the first and second magnetic element produces a magnetic field. A magnetic interaction between the first magnetic element and the second magnetic element couples the rotational motion of the driving element and the rotational motion of the driven element. The driving and driven elements are coupled at a predetermined rotational orientation with respect to each other.
