Star Jaw Couplings (Series ASJC)

Gear Couplings
Nylon Gear Couplings

SALIENT FEATURES

  • Simple construction - quick easy installation - No special tools required. 
  • Flexible insert caters for incidental angular, parallel and axial misalignment. 
  • Absorbs shock loads and damps small amplitude vibration. 
  • Insert design presets correct distance between hubs, using raised pads on each leg of the insert. 
  • Available in a range of stock bore sizes. Can also be supplied with finished bore & keyway. 
  • Unaffected by moisture, grease and oils-including non-aromatic and non-ketone solvents and temperatures with in range 40C to +100 C. 
  • Spacer coupling with spacer size depending upon the distance between two shaft ends (DBSE).

    SELECTION

    Details required for couplings selection
     
    1. Type of driven machine and operating hours per day.
        Speed and power absorbed by driven machine (if absorbed power is not known, calculate on power rating of
        prime mover).
    3. Diameter of shafts to be connected.
    4. Distance between two shaft ends in case of spacer coupling.
      
    PROCEDURE
     
    a) Service Factor
    Determine the required service factor from table.
     
    b) Design Power
    Multiply the normal running power by the service factor. This gives the Design Power which is used as a basis for selecting the coupling.
     
    c) Coupling size
    Depending upon the type of coupling required, refer to respective power rating table. Power rating can be interpolated in relation to speed parameters.
     
    d) Bore Size
    Check from the dimension table to see if bore capacity of the coupling is adequate. Otherwise select next higher size coupling.
