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 />
