Abstract
Abstract A flexible coupling for transmitting torque from an axially movable rotary driving member to a coaxially arranged rotary driven member. The coupling has an inner ring, an outer ring, and a plurality of generally S-shaped interconnecting resilient arms which permit axial flexibility while simultaneously providing reasonably stiff bi-directional torque transmission. The S-shaped arms automatically compensate for any radial lengthening of the coupling that occurs when the driving member moves axially relative to the driven member during torque transmission.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
A flexible coupling comprising in combination: bi-directional first torque transmitting means; bi-directional second torque transmitting means arranged coaxial to said first torque transmitting means and being free to move a predetermined axial distance toward and away from said first torque transmitting means; and bi-directional third torque transmitting means interconnecting said first and said second torque transmitting means, said third torque transmitting means including an inner member and an outer member, said inner and outer members being interconnected by a plurality of curved resilient arms, each of said arms adaptable to radially lengthen the amount necessary to compensate for axial movement of said second torque transmitting means.
Claim 2
Dependent Claim
106 words
A flexible coupling comprising in combination: bi-directional first torque transmitting means; bi-directional second torque transmitting means arranged coaxial to said first torque transmitting means and being free to move a predetermined axial distance toward and away from said first torque transmitting means; and bi-directional third torque transmitting means interconnecting said first and said second torque transmitting means, said third torque transmitting means including an inner member and an outer member, said inner and outer members being interconnected by a plurality of curved resilient arms, each of said arms adaptable to radially lengthen the amount necessary to compensate for axial movement of said second torque transmitting means.
Claim 3
Dependent Claim
118 words
A flexible coupling comprising in combination: first torque transmitting means; second torque transmitting means arranged coaxial to said first torque transmitting means, said second torque transmitting means being free to move axially relative to said first torque transmitting means; a torque transmitting diaphragm arranged coaxial to said first and said second torque transmitting means, said diaphragm including an inner ring, an outer ring, and a plurality of spaced S-shaped connecting arms, every other arm being inversely disposed, the terminal ends of said arms interconnecting said inner ring to said outer ring; first fastening means for connecting said diaphragm to said first torque transmitting means; and second fastening means for connecting said diaphragm to said second torque transmitting means.
Claim 4
Dependent Claim
118 words
A flexible coupling comprising in combination: first torque transmitting means; second torque transmitting means arranged coaxial to said first torque transmitting means, said second torque transmitting means being free to move axially relative to said first torque transmitting means; a torque transmitting diaphragm arranged coaxial to said first and said second torque transmitting means, said diaphragm including an inner ring, an outer ring, and a plurality of spaced S-shaped connecting arms, every other arm being inversely disposed, the terminal ends of said arms interconnecting said inner ring to said outer ring; first fastening means for connecting said diaphragm to said first torque transmitting means; and second fastening means for connecting said diaphragm to said second torque transmitting means.
Claim 5
Dependent Claim
19 words
The flexible coupling as claimed in claim 2 wherein said S-shaped connecting arms are each of substantially uniform width.
