Coupling : AC Series

Disk spring coupling --- AC Series (ACD,ACS,Taper attachment)

Disk spring coupling with a brand-new slit shape
ISEL originally designed inside clamp system!
Controls installation runout to the minimum & achieves highly precise centering!

Disadvantages of side clamp system : Disk fixing section gross deviation at shaft clamping --- ISEL originally designed inside clamp system --- Inside clamp system reduces disk fixing section deviation and increases shaft centering accuracy.


Low inertia & High rigidity
Easy installation
Cost reduction

Correspondent to TES Standards(*)
(*)TES Standards: organization standard in Japan Machine Accessory Association (TES1401)

Use examples

  • Connection between ball screw of feed shaft unit and servo motor on machine tools
  • Connection between driven ball screw and servo motor on precision stages
  • Connection between ball screw and servo motor on work unloading robots

Specification

  • Outer diameter : φ19 - φ56
  • Shaft diameter : φ3 - φ25
  • Transmission torque : 1N·m - 25N·m

Effect

Compared to the side clamp system, the inside clamp system reduces the load to the motor and support bearing by relieving stress to the shaft.
