Abstract A thermally insulated coupling for either rotatably or axially connecting a driving shaft and a driven shaft. In either application, the coupling is designed to present a high impedance to thermal heat flow between the two shafts. The present invention is applied to a basic rotatable coupling wherein a plurality of axially extending pins protruding from a flange on one shaft are mated with apertures in a flange on a second shaft. The present invention concentrically positions a spirally wound coil of metallic material between each drive pin and the wall of the corresponding aperture in which each drive pin is engaged. For application to the axial transmission of force between two axially aligned shafts, a plurality of bosses axially protruding from a flange of one shaft about the exposed edges of a corresponding plurality of metallic spiral coils which are disposed in cavities in an end flange of the second shaft.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
95 words
A thermally insulated coupling for axially connecting a driving shaft and a driven shaft, comprising: a first flange member, at least one boss, said boss being affixed to and axially protruding from said first flange member; a second flange member, said second flange member defining a mounting aperture; said mounting aperture being correspondingly positioned in axial alignment with said boss; a metallic, spirally wound coil means, said coil means being disposed within said mounting aperture for axially abutting said boss whereby either of said flange members is capable of transmitting axial force to the other.
Claim 2
Dependent Claim
95 words
A thermally insulated coupling for axially connecting a driving shaft and a driven shaft, comprising: a first flange member, at least one boss, said boss being affixed to and axially protruding from said first flange member; a second flange member, said second flange member defining a mounting aperture; said mounting aperture being correspondingly positioned in axial alignment with said boss; a metallic, spirally wound coil means, said coil means being disposed within said mounting aperture for axially abutting said boss whereby either of said flange members is capable of transmitting axial force to the other.
Claim 3
Dependent Claim
