Metallic block for detecting force operating on metallic V-belt and system for detection of operating force using same

摘要

The metallic V-belt includes endless belt-like supporting straps 15 and a multiplicity of metallic blocks 20 supported along the straps. The V-belt passes around a driving pulley and a driven pulley 2, 4. At least one of the multiplicity of metallic blocks comprises a notch formed in a part thereof, and a strain gauge attached to the notch. The strain gauge is intended to detect an external force applied to the metallic block. The force operating on the metallic V-belt is detected based on thus detected external force. The detected force is transmitted from a radio antenna 51 to a receiver 60 the belt also carrying a battery 52, a telemeter 53 and a Wheatstone bridge resister 54.
