Simple Construction – quick easy installation – No special tools required
1.
Type of driven machine and operating hours per day
Ω
Flexible insert caters for incidental angular, parallel and axial misalignment.
2.
Speed and power absorbed by driven machine ( if absorbed power is not known, calculate on power rating of prime mover)
Ω
Absorbs shock loads and damps small amplitude vibration
3.
Diameter of shafts to be connected.
Ω
Inset design presets correct distance between hubs, using raised pate on each leg of the insert.
4.
Distance between two shaft ends in case of spacer coupling
Ω
Available in a range of stock bore sizes. Can also be supplied with finished bore & keyway.
Ω
Unaffected by moisture,grease and oils-including non- aromatic and non- ketene solvents and temperatures within the range 40ºC to +100ºC.
Ω
Spacer coupling with spacer size depending upon the distance between two shaft end (DBSE)
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 tables. Power ratings 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.
