Measuring device for contactless measurement of a rotational angle of a rotating shaft using eddy currents |
摘要 |
A device for contactless measurement of a rotational angle of a rotating part that is rotatable via a rotating shaft. The device includes a cylindrical coil carrier with sensor coils and a tubular body of electrically conductive material that is firmly attached to the rotating shaft and which surrounds the coil carrier with radial play and has an electrically non-conductive zone extending circumferentially in the vicinity of the sensor coils. For the sake of an easy-to-assemble structure, the tubular body is slipped onto a face end of the rotating shaft in a form-fitting manner and the tubular body is surrounded with radial play by a housing cup, from the bottom of which the coil carrier, which is integral with it, coaxially protrudes. The housing cup is joined in a floating manner to a housing that receives the rotating part.
