ECHT-FLEX Coupling NEH Series  (Disk Couplings )

Product photo
  • This large-size series can be used up to 176,000N・m{18,000kgf・m}.
  • The spacer unit in the modular spacer models can be disassembled and assembled without disassembling the disk coupling portion.
  • The adapter hub type allows for larger shaft bore diameters than standard hubs.
  • ・Applicable shaft diameter :Φ72mm~Φ289mm
  • ・Torque range :8820~176000N・m

Features

  • ・In addition to the standard hub (N hub), an adapter hub (A hub) that can have larger shaft bore diameter, and a unit spacer hub (U hub) that allows the spacer unit to be removed and assembled without disassembling the disc coupling unit, are also available.
  • ・Gear coupling replacement type can also be manufactured to replace gear couplings.
  • ・Long spacer type can be manufactured upon request.
  • ・It is also possible to manufacture electrically insulated type using split spacers and insulating bolt sets.
  • ※If you like to coupling other than the key, please contact us.

Construction

Various specifications (Special specifications )

  • ・Single-Side Adaptor Hub Type (A-Hub Type ) ・Modular spacer type (U Type )

    The adapter hub type allows for larger shaft bore diameters than standard hubs. With the unit spacer type, the spacer unit can be mounted or removed without the need to disassemble the disk connecting section.

  • A-Hub Type

    Single-Side Adaptor Hub Type

    U Type

    Modular spacer type
  • ・Gear coupling replacement type

    A type with a shorter distance between the hub faces (J dimension), and the same overall length and hub length as the gear coupling. Can be replaced as-is.

    Eliminates the cost and labor of gear coupling lubrication. (Please contact Tsubaki representatives. )

  • ・Electrically insulated type

    Insulation resistance of 1 MΩ or more. Spacers on all products are subjected to withstand voltage/insulation testing. (conforming to JIS C 8201-1 )

  • Electrically insulated type
