Info

the Flexible Disc Pack The Flexible Disc Pack is the heart of the Kop- Flex High Performance coupling and transmits torque while accommodating axial, offset and angular misalignment. The Flexible Disc Pack is a series of precision manufactured discs assembled with washers and bushings into a unitized pack. The disc material is special, high strength, 301 stainless steel and each disc is Koplon*-coated, to help prevent fretting corrosion. Alternate disc materials, such as Inconel, are available; consult Kop-Flex. The discs have a “waisted” or “scalloped” link design. This results in increased flexibility and subsequent lower reaction forces on the connected equipment bearings. Further, stress distribution is uniform, which allows for increased misalignment capability and lower fatigue stresses on the discs. The scalloping also reduces weight and inertia. The discs are designed for infinite life with a factor of safety. Under loading, the disc pack is exposed to constant stresses due to torque, centrifugal force, axial misalignment and pretension and to alternating stresses due to angular and offset misalignment. The combined effect of these stresses is plotted on a modified Goodman diagram, which gives the disc material endurance limit boundaries. Generally, at normal operating conditions, and at maximum angular misalignment and axial displacement ratings, the discs operate with a nominal safety factor of 2. *Koplon is a Teflon based (PTFE) material of proprietary formulation. *Koplon and Teflon are trademarks and/or trade names of E.
