SENSOR DEVICE FOR MEASURING A LINEAR OR ROTATIONAL MOVEMENT OF A MEASUREMENT OBJECT

摘要

A sensor for measuring a linear/rotating movement (LRM) of a measurement object (MO): one sensor element (SE) to detect the LRM of the MO and emit measuring signals (MS), the sensor element having encoder element (EE) and sensitive element (SeE), the SE detecting a relative movement between the EE and SeE; an electronic evaluator to evaluate the MS of the SE; a first shaft (FS) coupled to the EE by a bearing; a second shaft (SS) coupled to the MO by a bearing; the FS/SS, by a releasable connection, are mutually coupled for rotation coaxially; the bearing has central axis (CA) and cylindrical bearing face (CBF) in the axial direction (AD) parallel with the CA has an axial extent (AE), and in the radial direction (RD) perpendicular to the CA has a bearing face (BF) internal diameter (ID); the connection has a “first axial”/“radial toothing” (FT) on one FS end, and a “second axial”/“radial toothing” (ST) on one SS end, the FT/ST mutually engaging form-fittingly; the connection in the RD is within the BF ID, and in the AD is within the AE of the BF; and the FS by another end facing away from the FT, and the SS by another end facing way from the ST, protrude axially from the BF.
