Patent ID: 6883997

Claim:
A device for connecting a shaft ( 10 ), in particular, a worm shaft, with a ring magnet, wherein said ring magnet has an inside face ( 14 ) that is in contact with an outside face ( 16 ) of the shaft ( 10 ), wherein on the outside face ( 16 ) of the shaft ( 10 ), there are deformation regions ( 18 ), by means of which a force-locking engagement, rotationally fixed connection of the ring ( 12 ) to the shaft ( 10 ) is assured, wherein the deformation regions ( 18 ) are impressed by means of at least two impressed features by means of an impressing die into the outside face of the shaft that is to be brought into contact with the inside face of the ring before mounting of the ring, wherein the deformation regions ( 18 ) are arranged approximately centrally in an axial direction on the outer face of the shaft in a region of the inner face of the mounted ring, wherein axial dimensions of the deformation regions ( 18 ) are smaller than an axial dimension of the inner surface ( 14 ) of the ring magnet, and wherein a radius of the shaft increases at the edges of the at least two-impressed features.
