SHAFT ANGULAR POSITION TRANSMITTER Russian patent published in 2002 - IPC

FIELD: instrumentation. SUBSTANCE: invention can be used for checking angular position of shaft, for instance, vehicle steering column shaft. Proposed angular position transmitter has cylindrical housing with fitted- in electrically insulating frame with inductance windings. Fixed and movable cylindrical conducting screens with perforated windows are placed inside frame. Movable screen is coupled with shaft under control by transmission mechanism made in form of bushing with eccentric external surface connected with shaft, and gear cluster installed on bushing for rotation by means of bearing provided with two external gear rims of different diameter. Transmission mechanism has also internal gear rims. First rim of larger diameter is in meshing with internal third gear rim fixed relative to housing, and second rim of smaller diameter is in meshing with internal fourth gear rim secured on movable screen. EFFECT: enlarged operating capabilities at relatively simple design. 10 cl, 3 dwg
