HOLLOW MAGNETIC BODY FOR DETECTING THE ROTATION OF A SHAFT

摘要

A hollow magnet body with an annular auxiliary body and produces them as a combined component using an injection molding process. In this connection, an inner diameter of the annular auxiliary body is embodied as greater than a diameter of the associated shaft so that a tubular section extends out from the material of the hollow magnet body between this shaft and the annular auxiliary body and is suited for the production of a press fit. As a result, the annular auxiliary body made of metal supplies the main component of the pressing forces, thus counteracting the danger of the hollow magnet body splitting.
