Abstract:
1. A torque limiting device for limiting transmission of torque between driven and driving members connected to the device, the device comprising: a first coupling flange having a first portion dimensioned and configured to engage a first section of the driven member and a first central bore with a first longitudinal axis; a second coupling flange having a first portion dimensioned and configured to engage a second section of the driving member and a second central bore with a second longitudinal axis, wherein said second coupling flange confronts said first coupling flange and is positioned relative to said first coupling flange so that said first central bore is in communication with said second central bore and said first longitudinal axis is substantially coaxial with said second longitudinal axis; at least one mechanical fuse releasably connecting said first coupling flange to said second coupling flange, wherein said mechanical fuse is dimensioned and configured to fracture in response to application of torque thereto of a first magnitude; a spindle disposed within said first bore and said second bore, said spindle have a outside diameter D first and second bearing assemblies disposed between said spindle and at least one of said first coupling flange and said second coupling flange so as to permit said spindle to rotate relative to said at least one of said first coupling flange and said second coupling flange, wherein said first bearing assembly is spaced from said second bearing assembly a distance D
