Can a mechanical motor coupling affect the operation of the drive?
Last Updated: 05/23/2014

Yes, but more as a problem to the entire system including the drive. Here is a list of Do’s and Don’ts:

DO:

  • Determine power requirements using both HP and torque to choose the proper diameter core for the application.
  • Use the highest possible rpm to transmit power, thus lowering the torque load on the shaft.
  • Operate the shaft in the largest possible radius, avoiding sharp bends or kinks.
  • Install the shaft properly, letting the casing be straight for several inches beyond the ferrule, clamping it into position whenever possible and avoiding excessive lengths.
  • Always use a means of shaft alignment; misalignment causes heat and mechanical breakdown of the coupling.

DON'T:

  • Bend a core into a radius smaller than recommended, even during shipment (if you are an OEM.)
  • Overlook direction of rotation in choosing a core.
  • Use the flexible shaft to support anything - it was not designed to be a handhold or a footrest or a support!
  • Ignore routine maintenance. Speak with your motor or coupling distributor for more information.
