A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

Famous quotes containing the word coupling:

    The time of the seasons and the constellations
    The time of milking and the time of harvest
    The time of the coupling of man and woman
    And that of beasts. Feet rising and falling.
    Eating and drinking. Dung and death.
    —T.S. (Thomas Stearns)
