PM Mili Motor Couplings |
|
Brakedrums may be used in conjunction with the whole range of PM couplings and may be bolted on either the driving flange or flexible half side of the coupling- ǾA - locating on the outside diameter or the coupling
Recommended brake drums for each size of coupling are show in the table, but ǾV is adjustable to suit "Non-standard" application |

1.1- Prediction of the System torsional vibration Characteristics---
An adequate prediction of the system torsional vibration characteristics can be made by the following method--
1.1.1-- Use the torsional stiffness as shown in the technical data, which is based upon data measured at 30o C ambient temperature ( C
1.1.2-- Repeat the calculation made as 1.1.1 but using the maximum temperature correction factor ST and dynamic magnifier correction factor M100 for the corrected rubber. Use tables below to adjust values for both torsional stiffness and dynamic magnifier i.e. CTdys = c X S |
| |
|
1.13- Review calculations 1.1.1 and 1.1.2 and if the speed range is clear of criticals which do not exceed the allowable heat dissipation value as published n the catalogue, then the coupling is considered suitable for the application with respect to the torsional vibration characteristics. If there is a criticalo in the speed range then actual temperature of the speed range then actual temperature of the coupling will need be calculated . |
| |
| 1.2-- PREDICTION OF THE ACTUAL COUPLING TEMPERATURE AND TORSIONAL STIFFNESS. |
1.2.1 Use the torsional stiffness as published in the catlogue this is based upon data at 30 C , and the dynamic magnifier at 30 C ( M 30 ) |
| 1.2.2 Compare the synthesis value of the calculated heat load in the coupling ( Pk ) at the speed of interest in the " Allowable heat dissipation " ( Pkw ) |
C = Temp = ( Pk / Pkw ) X 70
The coupling temperature is =O
then O = Temp + Ambient temp. |
| 1.2.3- Calulate the temperature correction factor St from 1.3 ( If the coupling temperature > 100 C , then use S Calculate the dynamic Magnifier as per 1.4. Repeat the calculation with the new value of coupling stiffness and dynamic magnifier. |
1.2.4- Calculate the coupling temperature as per 1.2. Repeat calculation until the temperature agrees with the correction factors for torsional stiffness and dynamic magnifier used in the calculation . |

1.4 Dynamic magnifier Correction Factor |
The Dynamic Magnifier of the rubber is subject to temperature variation in same way as the torsional stiffness |
