This diaphragm coupling originally developed for helicopter drive shafts has been redesigned for general industrial purposes. The diaphragm part employs a special profile processing (characterized by high torsional rigidity, flexible against bending/compression) to achieve high torque transmission.
Characterized by the capacity to flexibly absorb misalignments (low bearing load), this diaphragm coupling has been increasingly recognized to be essential for turbines and compressors of ever higher speed/larger capacity, as well as other rotating equipment for commercial power generator, steelmaking machines, equipment for vessels, and aircraft, etc.
Feature Special diaphragm shape enables to transmit a large torque, low load on the bearing ・Simple structure ensures easy installation/removal, lightweight ・Optimum for high speeds (100,000 rpm max.) ・Applicable in a wide temperature range (standard material: -100 ºC to +320 ºC (-148 ⁰F to +608 ⁰F)) ・Having no movable/frictional parts, this coupling does not require lubrication nor have noise, vibration, backlash, change in dynamic balance.
