| Selection Procedure |
| Selection based on Torque |
| SELECTION WHEN ACTUAL TORQUE REQUIRED FOR THE APPLICATION AND OUTPUT SPEED IS KNOWN. |
| A) |
Based on the input RPM, and required output RPM (N2), calculate ratio as described above. |
| B) |
Let the actual torque required for the application is T Kgm. |
| C) |
Depending on the duty cycle select the correct service factor (S.F.) from the table 8 given above. Multiply T by S.F. to get the design torque T1. |
| D) |
Stating from the lowest model, check the rated torque of the gearbox for the nearest ratio from our 'Selection Table Based on Torque' (Table 11 ). If the design torque is more than the rated torque, go to the upper model, till the calculated design torque is less than or equal to the rated torque. This is the Selected Model and selected ratio. |
| E) |
Using T & N2 and substituting the same in the above equation the Power required for the application can be found out. |
| F) |
Now, check the suitability of the selected model for Thermal Rating, Hollow Input Frame Size and the Overhang and Axial Load as described in Procedure 3.1 above |
