HIGH-SPEED ANGULAR DISPLACEMENT TRANSMITTER Russian patent published in 2003 - IPC

FIELD: measurement technology. SUBSTANCE: proposed device can be for checking angular position of steering shaft in automobile electromechanical booster of steering system. Transmitter comprises coaxially mounted rotor, stator and threaded movable element made in form of hollow cylinder. Said cylinder is manufactured of nonmagnetic conducting material. Threaded movable element is installed inside stator to form splined joint owing to splines made on inner side of stator and on outer side of threaded movable element. Threaded hole for rotor is made along axis of threaded movable element. With rotor rotating, threaded movable element displaces along stator axis, thus changing its position relative to measuring windings located on stator. This results in unbalancing of bridge measuring circuit in which measuring winding are included. EFFECT: provision of simple in design and adaptable-to-streamlined production transmitter for measuring angular displacement of shaft. 2 dwg
