| Data required for Coupling
Selection. |
| • |
Application
details (for service factor) |
| • |
Kilowatt and rpm of the
driver |
| • |
Shaft details of the driving
and driven equipment |
| (1) |
Determine the service factor
(SF) from the application and classification lists noted
below. |
| (2) |
Calculate the maximum Kw/1000
rpm rating:
Kw/1000 rpm =
(Kw x 1000 x SF) / rpm
Select the coupling which has a higher max rating. |
| (3) |
Check the Limiting Conditions: |
| a |
Check the hub bore capacity
is suitable |
| b |
Check the speed capability
and specify whether the coupling requires balancing. |
| c |
Check coupling dimensions
such as DBSE, Overall Length and Outside Diameter. |
|
Driver: Water Turbine
(75 Kw at 1500 rpm)
Driven equipment: Screw Compressor
Turbine Bore: 60 mm
Compressor Bore: 50 mm
Distance Between Shaft Ends: 140 mm |
| Service Factor for the Water Turbine
& Screw Compressor: SF=2 |
Kw/1000 rpm =
(75 Kw x 1000 x 2)/1500
Kw/1000 rpm = 100 |
|
Coupling selection based on the
maximum rating - ES130
Coupling Bore Capacity: 70 mm
Maximum speed for the ES130 is 5500 rpm Unbalanced
Minimum Allowable DBSE: 73mm (Solid Spacer) / 140 mm
(Bolted Spacer)
The ES130 HVII is acceptable
in this application
