Measurement transducer for small torques in form of rim linked to hub by spokes with measurement instruments on spokes

摘要

The transducer (40) consists of an outer rim (44) and an inner hub (42) linked by spokes (46). Distortion measurement devices (48) are located on the spokes and linked by a cable (50) to external recording equipment. The spokes react to torque and axial pressure forces applied to the appliance. The measurement devices react to surface distortion induced by the applied torque.
