3.6 Assembly of gear unit with hollow shaft (Option: A, EA)
NOTICE
The gear unit may be damaged by axial forces.
Bearings, gearwheels, shafts and housings may be damaged by incorrect fitting.
• Check the hollow shaft and the machine shaft for damaged seats and edges and fix all possible
damage before assembly.
• Use a suitable pulling device.
• Do not hit the hub with a hammer.
• Before and after pulling, align the hollow shaft precisely with the machine shaft. The hollow shaft
must not be tilted.
The required length of the key of the machine solid shaft must be sufficiently designed in order to
ensure safe transmission of forces. If splines are used (Option EA), the splines on the solid shaft of
the machine must be of correct size and tolerances.
Assembly and subsequent dismantling is facilitated by applying an anti-corrosive lubricant to the shaft
before fitting (e.g. NORD Anti-Corrosion Part No. 089 00099). Excess lubricant may escape after
fitting and may drip off. Thoroughly clean these points on the output shaft after a running-in time of
approx. 24 hours.
