Flexible coupling with torque measuring and detecting device
First Claim
1. A torque monitoring apparatus comprising first and second annular members, each annular member having an outer peripheral surface, said apparatus including a common hub, each said first and second annular members being connected to said common hub by separate support members, a plurality of indicating members mounted on each peripheral surface with each indicating member having one portion mounted on one peripheral surface and another portion extending over the said peripheral surface of said second annular member, said plurality of indicating members being substantially evenly spaced on said respective peripheral surface, at least one sensing member located adjacent to said peripheral surfaces, said sensing member being capable of detecting the relative movement of the said consecutive indicating members alternatively mounted on said peripheral surface of said two annular members, said separate support members comprising spokes connecting said first and second annular members to said common hub and said spokes being made from the same material as said first and second annular members.

Abstract
A flexible coupling and torque monitoring device includes a hub having two sets of flexible spokes extending radially outwardly from a common hub to respective separate rims; the rims are each provided with fingers attached at one end to one rim and with the opposite end extending over the other rim with the fingers of one rim interspersed with the fingers of the other rim; the rims are each attachable respectively to the end of a drive and driven shaft; a sensing member is located radially outwardly of the rims to detect deviations in the spacing between the fingers.
