Kop-Flex<sup>®</sup> MAX-C<sup>®</sup> Resilient Coupling

The OEM specified coupling on the pinion drive of a rotary kiln was not able to withstand the shock loading, causing the coupling to fail prematurely.

Kop-Flex® Coupling Solution

Kop-Flex was able to provide a coupling solution that would meet the torque, size and misalignment requirements of the application as well as reduce any shock loading during normal kiln operation. Upon investigation of the operating data, it was determined that a size #9 Max -C WB flex rigid coupling with 3/16” limited end float would be needed to accommodate the 13” shaft and 630,250 lb-in torque requirement. The “WB” blocks reduced the shock loading during normal kiln operation.

APPLICATION

Motor to pinion coupling on rotary kiln.

SOLUTION TYPE

Performance efficiency.

K2

  • Urethane wedged blocks for greater service life
  • High torque ratings and large bore capacity
  • Appropriate for medium shock and general duty industrial applications
  • Can be used as a non-lubricated replacement for many gear couplings
  • Used on electric motor driving cranes, pumps, feed rolls, fans, conveyors, bow thrusters and manipulators
  • Sold from catalog, off-the-shelf with rework or finish bored to order

WB

  • Wedge-shaped natural, nitrile or SBR rubber blocks in various hardness – typically custom engineered per application 
  • Used on synchronous and variable frequency motors driving compressors, kiln drives, steel mill main drives, crushers, ID and FD fans 
  • Wide range of sizes and torque capacities

CB

  • Cylindrical-shaped natural, nitrile or SBR rubber blocks in various hardnesses – typically custom-engineered per application
