DEVICE FOR CONTACTLESS MEASUREMENT OF SHAFT TORQUE Russian patent published in 2000 - IPC

FIELD: motor industry, in particular, steering gears with servomechanisms used for contactless measurement of steering shaft torque in the steer amplitude. SUBSTANCE: device has a torsion shaft, housing accommodating the induction coil frame with windings, and screens with perforated windows, as a rule, of a square section. The screens are installed near the shaft ends facing each other. The first screen with two rows of windows is enveloped by the other screen with one row of windows. The windows in the rows of the first screen are made with a shift. The windows of the other row. The row of windows of the second screen covers in width both rows of windows of the first screen. The screens are made of current - conducting material, mainly of copper, copper alloys, aluminium, or aluminium alloys. EFFECT: enhanced sensitivity, accuracy of measurement and simplified design. 8 cl, 3 dwg
