초록 ▼

A magnet assembly, having a disk-shaped magnet, which is made predominantly of metal material and has a through-hole and, by the through-hole, can be placed onto a region of a shaft made of plastic by a press fit. In the region of the magnet placed onto the shaft, the shaft has a diameter that is smaller than the diameter of the through-hole. The shaft has a plurality of radially protruding projections in the region of the magnet placed onto the shaft. The projections are distributed evenly on the circumference of the shaft and, with respect to the longitudinal axis of the shaft, having a radius, the double of which is oversized relative to the diameter of the through-hole before the magnet is placed onto the projections of the shaft.

대표청구항 ▼

1. A magnet assembly comprising: a shaft having a longitudinal axis; anda disk-shaped magnet of a metallic material having a through-hole by which the disk-shaped magnet is placed on the shaft by a press fit in an applied region of the shaft,wherein in the applied region, the shaft has a diameter smaller than a diameter of the through-hole, andwherein in the applied region of the shaft, the shaft has a plurality of radially projecting protrusions that are arranged evenly distributed on a circumference of the shaft with respect to the longitudinal axis of the shaft, each radially projecting protrusion runs out in a ramp to a cylindrical surface of the shaft towards a longitudinal end of the shaft, each protrusion having a radius, twice the radius of each protrusion being oversized with respect to a diameter of the through-hole before application of the disk-shaped magnet on the plurality of radially projecting protrusions of the shaft,wherein cavities between the radially projecting protrusions are at least partially filled with material of the protrusions during assembly of the magnet on the shaft. 2. The magnet assembly as claimed in claim 1, wherein each radially projecting protrusion is a web that extends parallel to the longitudinal axis of the shaft. 3. The magnet assembly as claimed in claim 2, wherein the webs extend axially out of the through-hole of the disk-shaped magnet at least one side. 4. The magnet assembly as claimed in claim 3, wherein the shaft is formed with an odd number of webs. 5. The magnet assembly as claimed in claim 2, wherein the shaft has an odd number of webs. 6. The magnet assembly as claimed in claim 5, wherein the shaft has three webs that extend between 20° and 60° in a circumferential direction of the shaft. 7. The magnet assembly as claimed in claim 5, wherein the webs extend over 40° in a circumferential direction of the shaft. 8. The magnet assembly as claimed in claim 2, wherein the shaft has a radially protruding stop shoulder at one axial end of the applied region formed with the plurality of radially projecting protrusions, and the disk-shaped magnet is configured to be pressed onto the shaft until it rests on the radially protruding stop shoulder. 9. The magnet assembly as claimed in claim 1, wherein the shaft is formed as a worm screw shaft in a region axially spaced from the region of the plurality of radially projecting protrusions.
