<strong>Synchronous</strong> <strong>Generators</strong> <strong>BG</strong> <strong>132</strong> / <strong>BG</strong> <strong>160</strong><br />

Chapter 4: 4.6 Installation of two-bearing generators (<strong>BG</strong> <strong>132</strong>)<br />

Permissible load on the shaft:<br />

• St<strong>and</strong>ard end shield (shaft ø 28 mm):<br />

Fr max = 2000 N (measured at an axial<br />

distance of 50 mm from the shaft outlet<br />

in the end shield)<br />

Fa max = 200 N<br />

Fa max<br />

Fr max<br />

• Reinforced end shield (shaft ø 32 mm):<br />

Fr max = 3800 N (measured at an axial<br />

distance of 50 mm from the shaft outlet<br />

in the end shield)<br />

Fa max = 380 N<br />

No other parts may be mounted to the mounting<br />

profiles of the generator housing.<br />

CAUTION<br />

4.6.2 Minimum clearances <strong>and</strong> regulations for cooling (twobearing<br />

types, <strong>BG</strong> <strong>132</strong>)<br />

In order to provide sufficient cooling the generator needs adequate ventilation.<br />

The cooling air is sucked on the rear side by the fan impeller <strong>and</strong> then blown to<br />

the front side through the cooling profiles along the housing. If necessary,<br />

adequate openings for cooling air inlet <strong>and</strong> outlet have to be provided.<br />

It is absolutely important to observe the following regulations for minimum<br />

clearances <strong>and</strong> cooling.<br />
