Abstract
A magnetic coupling device (1) is provided for coupling a first member (10) and a second member (11), coaxial with each other, so that they can jointly rotate about a common axis and/or translate along such axis or can perform relative rotary and/or translatory movements depending on the intensity of a torque or an axial force applied to one of the members. At least one of the members (10) has axially extending magnetized areas (12) each consisting of a row of axially aligned magnets (12′), the magnets (12′) in one area (12i) being axially offset relative to the magnets of an adjacent area (12j).
Claims9
A magnetic coupling device (1) for coupling at least a first and a second member (10, 11), coaxial with one another, so that the members can at least perform a joint rotary movement about a common axis (A) or a relative rotary movement, depending on the intensity of a torque applied to one of said members, wherein at least one of said members (10, 11) has axially extending magnetized areas each consisting of a row of axially aligned magnets (12′, 13′), wherein, for coupling said first and second members (10, 11) so that the members can perform, in addition to said rotary movements, also a joint translatory movement along said common axis (A) or a relative translatory movement, depending on the intensity of an axial force applied to one of said members, the magnets in the different rows are magnets of the same polarity arranged adjacent to each other in the respective row and the magnets in adjacent rows are of opposite polarity, and wherein the magnets (12′, 13′) in each row are offset relative to the magnets of an adjacent row so that ends of the magnets of adjacent rows are not aligned to form a circumference perpendicular to the axis (A) of the first and second members (10, 11).
