Abstract:
A pulley mounted on a pulley axle and having load sensing capacity, comprising:a. a pulley having a hub opening and a rolling element part installed therein; b. a generally cylindrical shaped body adapted to be placed inside said rolling element part and having an interior bore with two opposite ends for insertion there-through said pulley axle; c. a pair of generally cylindrical sleeve shaped covers for protecting said generally cylindrical shaped body; d. said generally cylindrical shaped body having an exterior central section to be brought into contact with said rolling element part, and two interior flanges at said two opposite ends of said interior bore of said body respectively to be brought into contact with said pulley axle, forming a cantilever configuration which is deformable when counter-loads are applied to said central section and said interior flanges of said body from said rolling element part and said pulley axle respectively; e. two outside grooves each located between said central section and a respective one of said two opposite ends of said interior bore of said body; f. a plurality of strain gauges affixed to said outside grooves of said body for producing a load sensing signal in proportion to said counter-loads applied to said body; and g. at least one electronic circuitry element affixed to said central section of said body for processing and outputting said load sensing signal.
