ECHT-FLEX Coupling NEH Series (Disc Coupling)

製品写真
  • This is a large disc coupling that can be used with a maximum torque of 176,000 Nm.
  • The unit spacer type allows the spacer unit to be removed and assembled without disassembling the disc joint.
  • The adapter hub type allows for a larger shaft hole diameter than the standard hub.
  • ・Applicable shaft diameter: Φ72mm to Φ289mm
  • Torque range: 8820 to 176000 Nm

Features

  • In addition to the standard hub (N hub), there is also an adapter hub (A hub) that allows for a larger shaft hole diameter, and the disc connection part can be disassembled.
    We offer a range of unit spacer hubs (U-hubs) that allow for easy removal and assembly of spacer units without the need for additional spacers.
  • - Gear coupling compatible specifications can also be manufactured for replacing gear couplings.
  • -Long spacer types can also be manufactured.
  • - Electrically insulated specifications can also be manufactured using split spacers and insulating bolt sets.
  • *If you require fastening other than with a key, please contact us.

Structure

Various specifications (special specifications)

  • - One-side adapter hub type (A hub type) - Unit spacer type (U type)

    The adapter hub type allows for a larger bore diameter than the standard hub, and the unit spacer type allows for the removal and assembly of the spacer unit without disassembling the disc joint.

  • A hub type

    U-type

  • ・Gear coupling compatible specifications

    The hub face distance (J dimension) has been shortened to make the overall length and hub length the same as the gear coupling. It can be replaced as is.

    It eliminates the cost and labor required for oiling gear couplings, making it ideal for TPM. (Please contact us for details.)

  • - Electrical insulation specifications

    The insulation resistance is 1MΩ or more, and all spacers undergo withstand voltage and insulation tests after assembly (compliant with JIS C 8201-1).
